3 Foolproof Tips for Healthy Crops This Summer

WP Law - Wednesday, June 23, 2021

Summertime can be a challenging season to keep your crops healthy. During the dry and hot season, it may take a lot of water and money to yield the crops you have in mind. Check out these three foolproof tips to help you achieve the best, healthiest crops with less money and hassle.

  1. Healthy Soil Yields Healthy Crops
  2. A healthy crop begins with healthy soil. In fact, you may always struggle with your crops unless you give the soil the TLC it needs. Sandy soil will not retain moisture long enough to give your crops the necessary moisture. Adding plenty of compost to the soil each growing season will ensure it is nutrient-rich to promote healthy crop growth.

  3. Manage Weeds from the Start
  4. Dealing with weeds is one of the biggest challenges that farmers and gardeners face. Pesky weeds can outcompete or smother your crops, which leaves them difficult to harvest or negatively impacts crop growth. For best results, start dealing with weeds immediately with proper garden cultivation practices. Weeds are easiest to manage before they grow out of control.

  5. Use the Proper Irrigation System
  6. The number one way to ensure your crops receive the water they need to be healthy is to install a drip irrigation system. You will be able to deliver water to the crops' roots which is the most effective way to irrigate. With a drip irrigation system, you can also save money on watering costs because you are watering the roots only, instead of wasting water spraying the crops' leaves.

2 Agricultural Water Pumping Systems Built to Withstand Any Task

WP Law - Thursday, January 21, 2021

Crops can’t grow without the right irrigation, and irrigation isn’t successful without the right water pumping systems. From watering plant roots to frost protection, without the right systems in place, you risk the welfare of your crops. With that in mind, take a look at two agricultural water pumping systems built to withstand any task.

#1: Overhead Systems

In traditional agriculture, overhead irrigation simply means the water comes down onto the plants through the use of sprinklers. With reliable pumping systems, the water comes through nozzles to provide adjustable amounts of irrigation to your particular plants. Overhead systems include:

  • Impact sprinklers
  • Movable aluminum piping
  • Traveling systems
  • Effluent spray fields
  • Frost protection applications
  • Wet log storage

#2: Drip Irrigation

Unlike overhead applications, drip irrigation puts water right at the roots through pump systems that deliver water either right above or right below the soil surface. The benefits of a drip system include losing less water to evaporation and maintaining nutrients in the soil. The primary applications for drip irrigation include:

  • Orchards
  • Vineyards
  • Truck crops such as berries, corn, tomatoes, and watermelon
  • Sub-surface drip systems

For any irrigation to be effective, it has to have a pumping system built to meet the task. Sometimes, conventional equipment fits the bill for your needs. Other times, you want and need a custom design to make sure your crops are getting the water they need when they need it. The good news is there’s a team of experts that can handle both. With over 100 years of experience, they’re your go-to for all of your agricultural water pumping needs. Contact W.P. Law, Incorporated today to get started.

A Quick Guide to Frost Protection

WP Law - Thursday, December 10, 2020

Are you using your irrigation system to help protect your crops this winter? When the temperature drops and there’s a frost or freeze warning, instead of worrying about the losses, take a look at how you can prevent damage. Here’s our quick guide to frost protection.

How Water Protects Crops from Frost

It might sound counterintuitive, but watering when the temperature drops to freezing or below can actually protect your crops from frost and freeze damage. Heat fusion is the key and occurs when the air temperature drops below 32°, and the freezing water coats the plants. The process of water freezing is what produces the heat.

Here’s how it works:

  • The irrigation system runs as temperatures drop
  • Water on the plants freezes, creating a reaction that releases heat under the ice, creating a 2° to 5° buffer
  • The heat given off as water turns to ice and protects the plant from the freezing air.

What You Need

When using irrigation to protect plants and crops from frost, the ice must be clear and drip from the plants. If the ice solidifies and turns milky-colored, there isn’t enough water to protect from frost. You’ll need to boost water application. The ice and dripping water should be uniform across the plants, and the irrigation should be continuous. Increase the amount of water as the temperature drops and continue irrigation until the air temperature rises above 32° and the ice melts.

Frost protection during the winter months is critical to your crops’ survival. The experts at W.P. Law, Inc. can guide you in your agricultural irrigation throughout the year, including the freezing months. Contact their team today for more information.

2 Spooky Things That Can Damage Your Irrigation System

WP Law - Thursday, October 15, 2020

Do you rely on your agricultural irrigation system to keep your farm afloat? Some downright frightening issues can impact that system. Take a look at two spooky things to look out for and avoid.

1: Rodent Damage

Drip irrigation systems have many components that are above ground including drip tubing, emitters, and micro-sprinklers. These items are easy targets for rodents looking for a cool drink. Larger exposed pipes that are left open can also make a nice nesting site during the cold winter months. Unfortunately, many growers don’t realize these problems until it is time to start things up in the Spring.

2: Frozen Lines

It’s vital to take advantage of any automatic drains in your irrigation system in the winter months. Check them regularly to be sure they’re functioning properly and that they remain open and not plugged. Be sure to drain the lines in all of your systems in the fall before any winter freezing to avoid cracks in the equipment and to prevent broken pipes and lines.

Poor preparation for the winter months and crazy weather can cost you big time when it comes to your watering system. For help with prep or repair recommendations should damage occur, trust your agricultural irrigation to the experts at W.P. Law, Inc. With the experience and know-how to get the job done right, they’ll help keep spooky damage far away from your system.

WP Law - Thursday, April 23, 2020

What do you know about water conservation technology? Proper irrigation is vital for crops, landscaping, athletic fields, parks, and more. But all that water can cost a whole lot of money, breaking your budget and putting a strain on your bottom line. The good news is, we can help. Here’s how you can save money with smart controller technology.

What is Smart Controller Technology?

You want to get optimum performance from your irrigation system, which means watering the right amount at the right time. Sometimes you can get it right, and sometimes it’s a crapshoot.

Smart controllers utilize an on-site weather station to adjust irrigation run times on an as needed basis. Smart controllers also take into account the soil type, plant material, and historical climate data. Because smart controllers can “think” they can make irrigation run-time adjustments. They will allow the irrigation system to run more frequently during dry periods and less frequently on cloudy or rainy days.

Benefits of Smart Controller Technology

Saving money is at the top of everyone’s priority list, but so is using less water. Good thing those two go hand in hand. Using industry standards to install this state-of-the-art irrigation controller, you can take advantage of some of these benefits:

  • Uses reliable data from your soil to provide the proper amount of irrigation
  • Save money by using less water
  • Enhance the quality of your crops and the appearance of your landscaping with proper watering
  • Reduce landscape loss due to over or under watering
  • Protect the water supply in your region

  • Do you want to save 20-50% on your water usage? You can with the right conservation tools for your landscaping or agricultural needs. Contact WP Law today for more information on how smart controller technology can change the way you irrigate.

    Surprising Ways Irrigation Can Protect Your Crops This Winter

    WP Law - Thursday, January 16, 2020
    Surprising Ways Irrigation Can Protect Your Crops This Winter

    Do you need to run your agricultural irrigation system during the winter? While you know the value of winterizing your sprinklers before a freeze, you may not know that your crops still need water during the cold months. Here’s how proper winter irrigation will protect your plants.

    1. Water Traps Heat in the Soil

    Moist soil retains more heat than dry soil, which is vital for your crops if the temperatures drop below freezing. Watering your crops the day before an expected freeze will reduce the risk of frost. Damp soil insulates the roots and helps to keep your plants stronger in cold weather.

    Utilizing frost protection sprinklers during the winter is a proven way to prevent frost injury. These sprinklers not only keep the soil moist, but they also keep the leaves and roots of your crops warm.

    2. Roots Grow All Year Long

    Even though your crops may appear completely dormant during the winter, you can’t see the activity happening below the surface. Many people assume their plants won’t need any water until the spring. But that’s not the case. Roots grow all year long. If you want your crops to thrive, you need to provide the roots with enough moist soil to survive the cold, dry season.

    If it doesn’t rain enough, the soil will dry out. Even evergreens and shrubs lose a lot of water when the temperatures drop. The roots may become weak or brittle, and your crops won’t be as healthy during the spring. You can prevent this from happening by watering your plants at least once a month during the winter.

    Moist soil will benefit your crops all year long, and you shouldn’t overlook the importance of irrigation during the winter. W.P. Law, Inc. wants to make sure your plants survive the next freeze. We offer a range of products and services designed to help your crops. Connect with us online to get your agricultural irrigation system ready for winter.

    How to Check for Irrigation Leaks

    WP Law - Thursday, August 22, 2019
    Irrigation Leaks

    How do you find a leak in your agricultural irrigation system? Built-in safeguards make it easy.

    Agricultural irrigation is a life-giver. There’s no doubt about the positive impact watering systems have made on modern-day farming. Unfortunately, when your irrigation system springs a leak, you might wish for simpler days. Problems in your system can be hard to find. Here’s how to identify them:

    Keep an Eye on Your Water Bill

    One of the main draws of modern irrigation systems is their ability to save water and keep expenses low. Leaks rob you of the benefits, so it’s important to stay on top of monitoring your bills. If you see unexpected spikes in usage, it’s time to look for leaks.

    Put Your Isolation Valves to Work

    Hopefully, upon installation, you added isolation valves between sections of your irrigation system. These might seem like a waste of money at the time, but they’re more than worth the expense when it comes to containing a leak. Isolating sections will allow you to check each one to see where the culprit lies. If you haven’t installed isolation valves, prepare to do some digging!

    Check for Lumpy, Wet Soil

    An especially nasty problem occurs when your irrigation is on an incline. There’s no telling where your leak might be as any water will flow downhill. It can help to mark down where you bury the major joints for your irrigation line. Otherwise, you’ll have to keep an eye out for saturated soft spots or lumps in the soil.

    Top Four Winter Pond Care Tips  

    WP Law - Thursday, January 24, 2019
    winter lawn care

    A well-designed pond requires very little winter maintenance to keep aquatic life alive. However, a few simple steps taken before and during months with freezing temperatures can ensure your pond will remain looking beautiful for years to come.

    Maintaining Plants

    Prune off any yellowing plant leaves in the fall. Leaves should be removed from the skimmer daily during the fall too. Dispose of any dead organic debris from the surface and surrounding area of pond to prevent the water from turning dark brown.

    Pump Care

    Pumps can remain running during the winter in most parts of the southern US. If you choose to remove your pump it should be stored in a room that will remain above freezing. If the weather in your area is typically warm year-round, turning off the pump isn’t necessary.

    Keeping Fish Alive

    As part of winter pond maintenance, you want to protect any fish you have living inside the outdoor water feature. New pond owners worry that freezing temperatures mean a pond full of dead fish. The good news is fish can survive the winter months as long as the pond doesn’t freeze completely and an air hole is provided. Ponds at least two feet deep typically will not freeze. In addition to providing an air hole, a pond aerator is useful for supplying fish with the oxygen they need to survive.

    Removing Snow from Surface

    Snow that accumulates on the surface of a frozen pond can block sunlight from penetrating the surface of the water. Lack of sunlight is detrimental to both plants and fish you have inside the pond. Removal of snow from part or all of a pond is critical during the winter months. Installing a de-icer in a shallow area of the pond prevents snow and ice buildup in a section of the pond.

    Am I Maximizing the Efficiency of my Pump

    WP Law - Thursday, January 24, 2019
    winter lawn care

    Pumps are usually one of the more overlooked parts within a lawn irrigation system, but they are incredibly important. You may need professional assistance when you are changing out pumps or restructuring your lawn irrigation, but it is always good to know the basics.

    The Different Types of Pumps

    Maximizing your pump means picking the right kind of pump. The two major types of pumps used in lawn irrigation systems are submersible and centrifugal. The type of pump you used is based primarily on your irrigation water source. Submersible pumps are typically used in well applications and centrifugal pumps are used on surface water applications.

    Measuring Performance

    Optimizing the use of your pump means understanding exactly what key performance metrics to look for. All pumps operate along a curve that is unique to that manufacturers pump model. This pump curve plots pressure versus flow rate. As pressure decreases, rate of flow generally increases. It is critical to know the required flow rate and pressure for an application in order to make the proper pump selection. Also, make sure to winterize your pump system if you live in a place where the temperature drops to below freezing.

    How do I Protect my Plants this Winter 

    WP Law - Thursday, January 24, 2019
    winter lawn care

    If you want great looking plants during the warm season, protect them during the cold seasons. Proper handling of your plants during autumn and winter prevents frozen roots and foliar damage. Take a look at some best practices that you can implement today.


    Using an organic material to mulch will not only protect the plant’s roots from freezing temperatures but will also create better soil. As the mulch breaks down, it will put much needed nutrients into the soil. Use a new layer of mulch every autumn. Keep it around three inches deep, and leave a 0.5 inch space around the stem of the plant for air circulation.

    Frost Fabric

    Plants can use blankets as well! If you have small trees or large shrubs, you can use a burlap swath to protect them from freezing weather. Remove any cover during the daytime, and make sure that they reach all the way down to the roots of the plant. Do not bind any cover to the plant - make sure that you stake them away from the stem to keep the stem from becoming injured.

    Water Correctly

    The right watering tactics can be used to protect plants during a night frost. The soil should be thoroughly watered during the day. The wetter soil will hold the heat better than the dry soil, which will protect the plant’s roots and keep the surface temperature from dropping too low. The appropriate irrigation system can help you water more easily based on the predicted night time temperature.

    Winterization Guide for your Irrigation System  

    WP Law - Tuesday, November 13, 2018

    With the growing season coming to a close and winter just around the corner, now is the time to turn our attention to winterizing our irrigation system. The old adage of an ounce of prevention is worth a pound of cure certainly holds true when it comes to preparing our irrigation system for the winter. A little bit of time now will save a lot of time and expense when spring rolls around and it is time to get things running again.

    Protecting Your Irrigation System

  • Any exposed piping is susceptible to damage from freezing weather. To help minimize damage due to freezing, drain all water from your system. Valve and sprinkler risers should be equipped with drain valves that are below ground. These drain valves should be opened and left open during the winter months. If above ground piping cannot be drained, it should be well insulated.
  • Drain all pumps and filters. Most pumps have a drain plug located at the base of the volute (or pump casing). This plug should be removed and left out over the winter. If the plug is reinstalled, condensation can accumulate in the casing and cause freeze damage. Power should also be switched off to prevent the pumps from being accidentally turned on, as running them dry can cause severe damage.
  • Shut down the controller for automatic systems. This prevents accidental activation of the pumps, which could be damaged by running dry if they have been properly winterized.
  • Backflow preventers and valves above the ground should be protected. Insulation tape can be used. Drain outlets on backflow preventers and air vents should not be blocked in the process.

  • Winter weather can be a source of severe damage to your irrigation system if it is not properly protected. W.P. Law has economical solutions to fit your needs. Contact your irrigation specialist today for a safe transition into winter.

    Best Applications for Sub-Surface Drip Irrigation  

    WP Law - Wednesday, October 17, 2018

    Sub-surface drip irrigation is an irrigation technique that varies from the conventional practices which most individuals are used to. Unlike surface irrigation or traditional drip irrigation, this method uses drip tubes buried under the soil surface to supply water to plant roots. The depths at which the drip tubes are buried depend on the crop being watered and the farming practices employed. It is a costly watering system because it requires expert design and maintenance, but the fact that it delivers water directly to plants roots makes it very effective.

    Sub-surface irrigation eliminates many of the effects of conventional irrigation methods such as ponding, surface infiltration, surface water runoff (leading to erosion), and excessive water losses through evaporation. Water moves out of the drip tubes in all directions and wets the soil around roots. With a well-managed sub-surface irrigation system, it possible to maintain a high degree of uniform water application throughout your fields. Plus, water is only applied underground instead of to the soil surface where weeds could easily germinate. This reduces weed growth and makes it possible for crops to enjoy more nutrients from the soil.

    Best Applications

    In arid, semi-arid, hot and windy areas – The system is best for such areas with low rainfall and limited water supply because of its low evaporation rates compared to conventional irrigation methods. Countries such as Israel heavily rely on this technique in their farming.

    For weed control – The system can help reduce weed growth substantially.

    Growing crops that require dry surface conditions – Some crops benefit from a drier soil surface and foliage because of reduced potential for fungal diseases.

    Medium and large-scale production – The system is relatively complex and in most cases automated, so it’s not best for small-scale farming.

    If you are considering sub-surface irrigation, contact W.P. Law, Inc. today for more information!

    Beginners Guide: Water Well Basics  

    WP Law - Wednesday, October 03, 2018

    If you are planning on having a well drilled or you are a new well owner, it is essential to know well basics.

    Types of wells

    • Driven wells - They are made by driving a pipe with a well point into shallow water-bearing gravel or sand.

    • Dug wells – They are wells excavated by hand using a shovel to a level that is below the water table. They are usually lined with tiles, stones or bricks. They are shallow and easily get contaminated.

    • Drilled wells – they are constructed using a rotary drilling machine. They are usually more than 100 feet deep.

    Well contamination

    It is easy to contaminate a well especially if it was not well constructed. Contaminants can easily slip into the well if toxic materials are dumped close to the well and leach into the aquifer contaminating the groundwater. Consumption of water from a contaminated well can be dangerous. It is essential to have your well tested on a regular basis for pathogens, contaminants and other chemicals.

    Potential sources of contamination include;

    • Microorganisms such as bacteria, parasites, and viruses

    • Nitrate and nitrite present in human waste and chemical fertilizers

    • Heavy metals

    • Fluoride

    • Radionuclides

    Protecting your well from contamination

    Proper well maintenance which includes an inspection every ten years is important. You should also install a well cap to prevent hazardous materials from falling into the well. Use caution around the well and do not put any dangerous substances close to it.

    If you are planning to own a well in the future, talk to the experts at W.P. Law Incorporated.

    The Modern Way to Conserve Water with Agricultural Irrigation

    WP Law - Thursday, August 16, 2018

    In many regions of the country, water is becoming an increasingly precious resource; and sustainable, profitable agriculture depends more and more upon the effective management and conservation of resources.

    Fortunately, modern irrigation technology has provided a number of ways in which the consumption of water can be minimized

    Drip (Micro) Irrigation Systems

    In a drip irrigation system the water is delivered close to the roots of the plants minimizing losses due to runoff and evaporation that typically occur when a traditional sprinkler or spray system is used.

    Drip irrigation also allows for water to be delivered during the cooler hours of the day, further reducing evaporation losses. Water can also be directed to the correct root depth to inhibit take up by weeds.

    It’s estimate that a well-designed and monitored drip system can reduce water consumption by as much as 70-80%.

    Proper Scheduling

    Effective scheduling depends knowing the water requirements of the crop you are growing and having the ability to accurately measure the amount of moisture in the soil.

    Proper scheduling can not only save you money in pumping costs, but can also reduce the potential for certain diseases and save you money on your spray bill.

    Smart Irrigation Systems

    The most advanced irrigation systems now include sensors which can monitor the levels of moisture in the soil and make any necessary adjustments to the amount of water being delivered.

    These systems therefore precisely optimize the amount of water being used, eliminating waste while also ensuring adequate hydration.

    A number of smartphone apps are also now available which allow farmers to control and adjust their irrigation systems remotely.

    The Difference between Overhead Irrigation Vs. Drip Irrigation

    WP Law - Thursday, July 12, 2018

    Farmers and growers often have preferences about the best way to water their crops. Whether you have a large area to irrigate or are planning a system for a smaller patch of land, knowing the difference between drip and overhead irrigation will allow you to make the best selection for your needs.

    Enhancements in sprinklers and water lines have made newer systems incredibly water efficient compared to older practices. When measuring efficiency, we must consider more than the amount of water used.

    Advantages of Drip Irrigation

    • Slower distribution of water prevents excessive runoff and possible soil erosion.
    • Offers much better water efficiency than sprinklers
    • Waters only those plants or crops alongside the lines, not weeds and unwanted plants that may be on the grounds
    • Avoids potential water waste that may occur with sprinkler systems due to evaporation and winds
    • Excellent for chemigation and fetigation of crops

    Advantages of Overhead Irrigation

    • Ability to cover a larger area as sprinklers imitate rainfall
    • Excellent for frost protection if designed properly
    • Requires less filtration unlike the frequent flushes necessary to keep drip systems from experiencing plugged lines
    • Generally has lower maintenance costs and a longer lifespan of use

    7 Irrigation Tips Guaranteed to Make Your Farm Expansion Easier

    WP Law - Thursday, March 22, 2018

    Expanding a farming operation often involves more than just planting more acres. Many farmers know they will need to improve and expand their current irrigation systems to account for the increased acreage. There is a lot to consider when updating or expanding an irrigation system. Here are several things that need to be considered.

    • There is no universal answer for the best irrigation system to install. This decision usually comes down to the cost per acre to install and operate the system and the monetary value of the crop being grown. High value crops such as vegetable and orchard crops are usually irrigated using drip or micro irrigation. In addition to high uniformity and high efficiency, another plus is that the irrigation will not interfere with other field operations such as cultivating, spraying and harvesting.
    • It is easier to increase energy efficiency to reduce costs and waste than in the past. Variable frequency drives (VFD's) can greatly improve the performance and efficiency of electric irrigation pumps. Ask an expert for help in making the right choice for your farm.
    • Buried pipelines cost more to install, but they rarely leak when properly installed and maintained. Above ground pipelines are less expensive to install, but they are more susceptible to damage from equipment and rodents causing multiple leaks. In some cases up to 30% of the water is wasted before it reaches the crops. Keep this in mind when deciding which system you need.
    • Don't forget to speak with your electric company about different charges that probably exist for electrical usage during off-peak hours. Keep in mind that not all crops thrive with off-peak watering.

    The Definitive Checklist for Healthy Crops This Spring

    WP Law - Thursday, March 15, 2018

    Farmers and home gardeners share many of the same tasks when it comes to planting their crops. Although there is a difference in scale and because of that, practices. Here is a look at some of the things that successful farmers know that home gardeners can apply to their summer gardens.

    Things All Producers of Crops Can Do in the Spring to Increase Production

    1. Prepare the soil prior to planting. This begins with a soil test. It is important to know what nutrients need to added to the soil for it to produce the optimum yield for the crop you are growing. In addition to adding nutrients, the soil needs to be tilled to reduce weeds and improve water infiltration and aeration. In some cases deep tillage is required to break up hard pan.

    2. Understand your crop's normal cycles. By understanding what your crop is supposed to do and when will help you identify potential problems early. Things such as how long after planting should you expect the seeds to germinate and how long after germination should you expect flowering are good to know. Also knowing the number of days it takes to produce a crop can help you schedule planting dates.

    3. Know the nutrient and water requirements at different stages of growth. This can help you adjust fertilizer and irrigation schedules. Also know if you crop is susceptible to insects or disease a various stages of growth. This can help you develop a spray program to minimize disease and insect damage.

    4. Keep in mind that you will improve your harvest if you alternate how you do things from year to year. Farmers learned many years ago the importance of crop rotation. This same principle applies to home gardeners as well, just on a smaller scale. For the home gardener, simply plant your crops in different places in your garden each year.

    The Art of Irrigating Your Orchard this Spring

    WP Law - Thursday, February 15, 2018
    Crop Irrigation

    Adequate irrigation is essential for the healthy development of the trees and fruit in any orchard.

    But care is needed because relatively small changes in irrigation patterns can lead to significant variations in the amount and quality of fruit produced.

    A number of variable factors can make it difficult to gauge just how much irrigation trees are likely to need, particularly at the beginning of the annual growing season each spring.

    The Danger of Excessive Irrigation

    Trees require less water than many people assume during this time of year, and the appearance of dryness on the top of the surrounding soil, or in surface plants and grass, is not necessarily an accurate indication of moisture levels at tree root depth.

    So it is easy to over-water at this time, which can retard the growth of the trees developing feeder roots or even lead to them rotting. It may also leach vital nutrients from the soil.

    The Three Key Metrics You Need to Know

    There are three measurements of which you need to be aware to ensure that your trees get enough, but not too much, water --

    • the amount of water your system is delivering
    • the amount of that moisture which is retained by the soil
    • the rate at which the trees are using water

    The water delivered by your system should be relatively simple to control. But the amount of moisture retained in the ground may vary considerably; sandy and rocky soils absorbing much less than heavier loams and clays.

    The rate of water usage by trees depends mainly on their size and can be roughly calculated according to height, width and amount of leaf cover.

    But water uptake also varies according to regional and climatic differences in hours of daylight and sunshine, temperature, humidity and wind.

    Trees also use water more slowly in spring than in the later growing months. As a rule of thumb, an amount of water which lasts a tree for 14 days in April will last for six days in May and just three in July.

    Accurate Moisture Measurement

    There are a variety of moisture sensors available on the market today. Accurate moisture measurement is critical to determining the best irrigation schedule for your orchard crops. By knowing what the moisture level in the soil actually is, you can adjust your irrigation schedule to have the right amount of water available to the tree when it is needed the most.

    3 Reasons to Consider a Custom Fabricated Pump Station

    WP Law - Thursday, January 18, 2018
    Crop Irrigation

    Pump applications will always vary depending on where the pump systems are to be used, material to be pumped, and type of project at hand. If you are about to undertake a certain project and are not sure whether to use standard pump systems or custom fabricated pump systems, go through these few reasons why the latter is a better option:

    1. Fits your specific operation perfectly

    One of the greatest benefits of customization in any industry is the development/creation of systems that meet the specifications of the owner. With a custom fabricated pump station, your pumping system will be tailor made to perform operations that are specifically targeted to your project’s goals. All you need is to consult a professional and experienced pump fabrication expert to develop a pump station for you according to your specifications.

    2. Saves you money in the long-run

    A custom fabricated pump station leaves room for expansion in case your operations grow in the future. This saves you money in the long-run as upgrading the system will be easy and swift. It also saves you money by ensuring that your operations are streamlined from the word go.

    3. Maintenance on such systems is easy

    It’s easy to maintain a custom fabricated pump station especially when it’s the fabricator or installer offering the required routine maintenance services. The fabricator understands the system inside out, making it easy for them to identify where an emergency problem is and how to solve it fast. Most manufacturers also offer maintenance services at a reduced price for a certain period to guarantee the quality of their work.

    A custom fabricated pump station is definitely the better option in many projects. However, it’s always smart to consider professional advice on the best option depending on the type of project at hand.

    2 Reasons Why Traveler Irrigation Systems Are Your Secret Weapon  

    WP Law - Thursday, January 11, 2018
    Crop Irrigation

    There are many different types of irrigation systems, each intended for different purposes. One popular type is the traveler irrigation system, which utilizes a large sprinkler mounted to a cart with wheels. This sprinkler is commonly referred to as a "big gun." The sprinkler sprays water in a radius of up to 250 feet. The sprinkler must be moved to irrigate the field. Here are two reasons why traveler irrigation systems are your secret weapon.

    1. Traveler Irrigation Systems Get the Job Done Fast

    The main advantage of traveler irrigation systems is that they can get the job done quickly and efficiently. The sprinkler of a traveler irrigation system typically can spray water in a radius of 80 feet to 250 feet. This makes the traveler irrigation system ideal for fields that are very large and need to be irrigated frequently.

    2. Traveler Irrigation Systems Are Versatile

    Another reason traveler irrigation systems may be your secret weapon is that these systems are very versatile. If you own a property that is rectangular in shape, such as an athletic field, traveling irrigators are a great option. Traveler irrigation systems can also be ideal if you need to apply a small amount of water in a relatively short period of time. Depending on the type of traveler irrigation system, they can be relatively easy to shift around a property, making them ideal for properties that are oddly shaped.

    If you need an effective and versatile irrigation system, you should consider a traveler irrigation system. For more information about the many advantages of traveler irrigation systems, don't hesitate to contact us here at WP Law.

    More Reasons to Irrigate Your Lawn During the Winter

    WP Law - Thursday, January 04, 2018
    Crop Irrigation

    Just like any other season when precipitation is sufficient, whether it’s in the form of rain, snow or ice, dormant warm season grasses will continue root growth and water and nutrient uptake although at a reduced rate caused by slowed metabolic activity. Cool season lawns and winter plantings of annuals to provide color have to have sufficient levels of moisture because they are actively growing. How do we accommodate these needs while preventing problems such as winterkill in turf or dead pansies due to lack of water?

    Drought conditions: It is not uncommon to have long stretches of time between rain events during the winter months. After several weeks have passed without rain, applying water once a week will be enough to keep your sod hydrated until natural precipitation occurs. If using an irrigation system be sure the watering cycle starts later in the day to prevent dangerous ice buildup on hard surfaces such as roads and walkways.

    Extreme cold fronts: During the winter months it is not uncommon to have cold, dry, and windy fronts move through. This, accompanied by rapid temperature drops during the day (or night) will cause the bark layer of shrubs and trees to split in effect girdling the plant. The same thing happens to the dormant turf. The soil will give up its moisture quickly in these conditions causing the grass to become “freeze dried.” The water that is in the grass plant at the cellular level freezes and expands destroying the tissues. This causes winterkill which shows up as what looks like large burned patches in the lawn during spring green up. Paying close attention to weather reports and irrigating before the arrival of the front, may help prevent or decrease the amount of winterkill observed later.

    Plants that provide color: Annuals planted to provide color in the landscape this time of year are actively growing and require moisture. Isolating these areas of color with drip irrigation will apply water as needed for growing healthy plants while preventing over watering nearby dormant turf.

    4 Ways a Drip Irrigation System Can Help You and Your Crops  

    WP Law - Thursday, November 16, 2017
    Crop Irrigation

    Fall can bring extreme temperatures, with blazing heat one day and chilly mornings on other days. This can be difficult on crops, especially those with shallow roots. Fall is prime season for plants to establish roots. The best way to promote root growth is with a good irrigation system.

    Why Use a Drip Irrigation System in the Fall?

    • Promote root growth: Especially with new plants such as winter vegetables and cover crops, root growth is essential for surviving the winter's cold. Use the drip irrigation system to boost your crop for the fall.
    • Save water: In the fall you don't have to worry as much about water evaporation. With regular intervals of watering, you can maximize water usage on your land, keeping your crop growing well into the cold season.
    • Adjust to the changing weather: On cooler days you can use less water and use more water on warmer days. Use a little mulch to help the water stay in the soil so you can have more time between water applications.
    • Save money: When you use less water in the fall, not only are you conserving an important natural resource, but you are also saving on your water bill and increasing your overall profits.

    A drip irrigation system can save you time and money. If you would like to know more how you can improve the water usage on your farm or small-scale garden, call us today.

    3 Savvy Ways to Conserve Water With an Agricultural Irrigation System

    Marketing W. P. Law, Inc. - Thursday, October 19, 2017

    Technology in irrigation is now helping farmers achieve more in the area of water conservation.

    Here are 3 savvy ways to conserve water with an agricultural irrigation system.

    Use of Sensors

    The use of soil moisture sensors and local weather monitoring stations allow farmers to obtain real time data on plant growing conditions. This information allows farmers to implement irrigation scheduling programs that allow them to apply precisely the right amount of water at the right time to provide ideal growing conditions for their crop. As a result, farmers have realized a reduction in the consumption of water and fertilizer through this concept.

    Precision Irrigation

    Precision irrigation involves placing the water closer to the plant’s root zone. Using methods such as low pressure drops on center pivots or drip/micro irrigation are examples of this technology. Precision irrigation improves system efficiency by reducing water losses from wind drift and evaporation. There are additional benefits with drip irrigation such as reduced disease problems.

    Irrigation Scheduling

    Irrigation scheduling is the process of determining the best time to run an irrigation system and the duration. Several factors need to be considered when determining the best irrigation schedule. Most notably is the weekly water requirement of the crop that you are growing. The water requirement can change as the crop maturity changes. Crops that are in the early developmental stage typically do not require as much water as crops that are in the fruit production stage. Another factor to consider when developing an irrigation schedule is the current weather conditions. Has it rained recently or has soil moisture been depleted by a long dry spell? Other factors such as soil type and slope should also be considered. An effective irrigation schedule will take into account all of these factors and allow the farmer to determine how much water to apply and when to make the application.

    3 Benefits of Custom Fabrication  

    WP Law - Thursday, September 28, 2017
    3 Benefits of Custom Fabrication

    Every agricultural and landscaping terrain has its own unique characteristics. Drainage, varying terrain, access to water sources, distribution to each field, and providing a means to regulate and measure the flow can provide challenges which off-the-shelf solutions are not available. Here are three benefits of custom fabricated solutions to bring water wherever it is needed:

    1. Innovative design solutions for equipment and components, whether you need to conserve water or have a unique landscape. Our designers use AutoCAD and other engineering technologies to design a system that gets water where you need it.

    2. Advanced fabricating, assembly, and finishing of equipment specifically designed to maximize your irrigation efforts and help your landscape grow. The right irrigation equipment is specifically designed to enhance your soil conditions, grading and location.

    3. Specialty welding of unusual piping configurations or to enhance current equipment. Custom irrigation systems for managed landscapes recognizes the fact that each landscape has different features from environmental conditions to water pressure and available flow. A customized solution for hard to irrigate landscapes often require one-of-a-kind solutions.

    Spring Maintenance: Is it Time to Upgrade Your Irrigation System?

    Marketing W. P. Law, Inc. - Tuesday, April 11, 2017
    Duo Pro dual-contained piping system

    Irrigation is essential for crop or garden growth, but if performed incorrectly, it does more harm than good. Thus make sure to avoid common irrigation blunders, such as:

    One of the most common drip irrigation mistakes is to use one emitter per plant. Though not necessarily a problem for small plants, this can be fatal to large ones. Not only do multiple emitters provide more water, but they ensure that if one emitter gets clogged, the others will still work.

    Incomplete Coverage

    Home and business owners looking to save money on rotor or spray irrigation may try to space the nozzles as far apart as possible, but this will create dry gaps. Instead, space the sprinkler heads at 50% of their diameter of throw. This spacing gives you head to head coverage insuring that you eliminate those dry spots.

    Pressure Problems

    Make sure that the water pressure is high enough for your system to work effectively. Although most irrigation systems can work with pressure as low as 20 PSI, the sprinkler heads will be operating at their minimum acceptable performance. Keep the pressure above the minimum level so that the system can work under all conditions.

    Timing Troubles

    Running your irrigation system during the day causes the water to evaporate before it soaks in, while nighttime irrigation encourages the growth of mold. Instead, run it during early dawn.

    What is Malathion and Can it be Used to Get Rid of Nuisance Insects?

    WP Law - Monday, March 27, 2017
    Nuisance Insects

    Farmers and landscapers are in a constant battle with nuisance insects, always looking for ways to eradicate them without having to coat their plants in undue amounts of harmful insecticides. Fortunately, there is an extremely low-risk way to get rid of nuisance insects called Malathion. 

    What is Malathion?

    Malathion is an insecticide that has become widely used thanks to both its effectiveness and its extremely low toxicity to human beings. Farmers use it to keep their crops from being devoured while landscapers spray it on their lawns, golf courses, and sports fields to kill off mosquitoes, ticks, chiggers, and other nuisance insects. It is the most common organophosphate insecticide used in the U.S. today.

    How to Eradicate Nuisance Insects with Malathion 

    The best forms of Malathion are formulated for landscaping professionals and are not readily available for general use. However, W.P. Law, Inc carries special formulations of Malathion that can be safely used by the general public. It is one of many insecticides that we carry.

    Be sure to contact us today to learn more and to see how we can put Malathion to work for you. 

    Three Signs it’s Time to Upgrade Your Pump

    Having the properly maintained irrigation equipment in place can take a lot of the headache out of irrigating your fields and make the entire process much more efficient. If you are wondering whether it is time for an upgrade, check out these three signs that it's time to replace your pump:

    1. Visible Leaks

    When your pump is operating be on the lookout for excessive leaks around the pump shaft and seal (or packing) area. Excessive leaks can be indicative of a seal failure or a damaged pump shaft.  If the latter is the case you may be a candidate for a new pump as pump shaft repairs can be costly.

    2. Reduced Performance (It just doesn't pump like it used to)

    Like any mechanical device, a pump will gradually lose some performance as wearable parts age. In many cases these parts can be replaced and pump performance restored to almost new. As a pump gets older and more problems begin to arise, you will eventually come to a point where it's more cost effective to replace the older pump with a new one instead of continuing to repair the older pump. It is important to note reduced pump performance can also be a symptom of other system components failing and it might be a good idea to have an expert evaluate your entire pumping system before any decisions on repairs are made.

    3. Parts for it can no Longer be Easily Attained

    Often times finding parts for older pumps can be almost impossible. This means that even if your pump requires a minor repair at some point, it could lead to serious delays and days or weeks of down time. Search for the availability of parts ahead of time, and if they are no longer readily available you are likely better off upgrading to a newer pump.

    How Your Irrigation’s Water Source Can Affect Your Crops

    WP Law - Monday, March 13, 2017
    Water Flowing from Faucet

    Nothing is more essential to a crop's growth than proper irrigation. Yet many people often overlook the importance of the water source they for their agricultural irrigation. With more and more significance being placed on growing crops with fresh, pure water, now is a better time than ever to reexamine how your irrigation's water source is affecting your crops.

    Water Contamination and Health Concerns

    Crops that are irrigated with contaminated water are one of the leading agricultural health concerns today. The most difficult part of this problem is determining the quality of your water. Livestock farms upstream of your water source may be leaching deadly bacteria in the water, and even water from an isolated pond or well can become contaminated. Not only can contaminated water stunt the growth of your plants, it can also lead to some serious health concerns for anyone that consumes the crops.

    Choosing the Right Water Source for Your Irrigation

    At W.P. Law, one of the services we offer farmers is helping them identify a proper irrigation water source. Along with designing the right irrigation system for your farm and installing the necessary equipment, part of the process of setting up an irrigation system is to locate a clean water source and ensure that it will provide continual contamination-free water.

    What are the Benefits of a Submersible Pump?

    WP Law - Monday, February 20, 2017
    Sump Pump

    If you've found yourself recently in the market for a new submersible, or other pump for your house or farm, you may be overwhelmed by all the available options. From submersible pumps to centrifugal pumps, the choices can seem endless. However, submersible pumps can hold a few unique advantages over other varieties and may be just what you're looking for.


    Submersible well pumps usually operate in a very narrow flow range.  To accommodate for a wide range of well depths, they are always multistage pumps.  The deeper the well (which means for static head) the more stages (greater pressure) are required.  The ability to match the number of stages with a reasonable small flow range allows pump manufacturers to create very efficient pump designs.  The key to getting the most efficient pump for your application is to have the well performance accurately measured by a competent well driller and to have the pump properly sized for your application based in the well information provided

    No Priming Necessary

    Submersible pumps are also used in applications where priming a standard end-suction centrifugal pump would be difficult.  Since the suction intake of a submersible pump is submerged, priming is not required.  It is important to remember that if you are using a submersible well pump in an application other than a well (such as a pond, wet well, stream, etc) that you must use a flow induction sleeve to force water to flow by the motor in order to keep it from overheating.

    Built To Handle Solids

    Most submersible sump pumps are designed to handle both solids and liquids without locking up during operation. This can be ideal for pumping out a flooded basement or emptying an old well, and choosing a submersible pump that specifically advertises itself as solids-capable can ensure you've made a durable purchase.

    For more information on some of the benefits of a submersible pump, contact the experts at W.P. Law. We're always happy to answer any questions you may have about your fluid handling services.

    How Irrigation Can Protect Your Crops from Frost

    WP Law - Monday, February 13, 2017
    frosty crop

    Everyone who has worked with plants knows that the winter months present an incredible danger for the health of crops due to frost injury. In fact, frost injury could potentially wipe out an entire crop if not protected properly. Many people have heard about using irrigation to protect crops from frost injury but don't understand why or how this works. Read below to learn more about how irrigation can protect crops from frost injury.

    The Water Protects the Plants from Injury

    While most people think that the layer of ice provides the protection with irrigation systems, it is actually the process of the water turning into ice that protects the plant from injury. As the sprinklers apply water to the plants and it begins to freeze, heat is released.  The scientific term for this is called the latent heat of fusion.  In other words, for water to turn into ice it must give up (or lose) heat. It is the heat that is lost during the freezing process that keeps the plants from being damaged.

    The Water Freezing Keeps Temperatures above a Critical Point

    In order for this process to protect the plants, water must be continually changing from a liquid state into a solid state.  Therefor frost protection sprinklers must be continually operated while air temperatures remain below freezing.  Frost protection sprinklers must not be turned off until the air temperature is well above freezing and the ice that has formed on the plants begins to melt.

    People looking at using an irrigation system to protect their crops from frost injury should contact W.P. Law for information. Make sure those crops receive the protection that they deserve.


    How to Choose the Best Irrigation for Your Farm

    WP Law - Friday, January 13, 2017
    building irrigation system

    Everyone knows that a proper irrigation system is vital to the success of a farm. Crops need quality water to survive and farmers depend on the yield and quality of these crops to support their family and the community. Therefore, everyone should consider these important factors before deciding on an irrigation system.

    What are the Needs of the Farm?

    This first factor is determining what the needs of the farm actually are because different irrigation systems serve different needs. What kind of crops are on the farm and how much water do they need? How often do they need this water? How much land is there to irrigate? The answers to these questions are important when deciding on the irrigation system for you.

    Drip Irrigation: This method is often used on high value crops such as vegetables, small fruits, and orchard crops. This irrigation method utilizes low volume, low pressure, emission devices to apply water directly to the root zone thereby reducing losses due to evaporation and runoff.

    Traveler Irrigation: In this form, a giant sprinkler head is moved through the field on wheels watering every crop. This is best used for farms on flat land conducive to this movement.

    Solid Set Irrigation:
    In this system, crops are fed by sprinklers attached to pipes placed underground. This is a common form of irrigation and makes sure that every plant is fed.

    What Kind of Water Source is Required?

    Farmers will need to consider the amount of water that is required to meet the needs of the farm. Some irrigation systems (traveler and solid set) require a tremendous amount of water over the growing season compared to drip irrigation. The water source (pond, well, stream) needs to be considered and could be a major factor in determining the type of irrigation system the farm requires.

    Choosing an irrigation system for a farm is a big decision with multiple factors. Anyone with questions or concerns should contact WP Law for more information today.

    What Impact Does Soil Have on My Irrigation?

    WP Law - Monday, December 26, 2016
    What Impact Does Soil Have on My Irrigation?

    Soil type is a crucial factor when considering irrigation applications. Soil is broadly classified based on three types of weathered rock described as sandy, loamy or clay. There are six different soil types that are most often identified. All six are simply a different combination of the three types of weathered rock and are as follows:

    • Sand
    • Silt
    • Clay
    • Peat
    • Chalk
    • Loam

    Each particular type of soil that makes up your agricultural land has its own unique behavioral characteristics. When comparing samples, three properties are considered important in understanding how soil will react. The particular composition of a soil is what determines to what degree it represents each of these three factors.

    Water Retention

    Water retention refers to the amount of water that can be absorbed and retained within the soil itself, much like calculating how much water a sponge can hold.

    Intake Rate

    The intake rate refers to how quickly your soil absorbs water. This would impact, for instance, how quickly water could be applied by an irrigation system. Some soil types require a slow trickle, while others can be quickly watered.

    Drainage Erosion

    Applying water faster than the soil can absorb it results in the wash off of soil. This is what is termed drainage erosion.

    Differences in soil structure affect liquid applications; everything from the type of fertilizer you use to the features of your new irrigation system. Knowing how your land will react based on your soil composition brings accuracy and efficiency to soil applications and equipment. Working with professionals like those at WP Law, Inc., can show just how valuable this knowledge can be for industrial, commercial, and residential applications.

    3 Tips for Preserving Your Submersible Well Pump

    WP Law - Monday, December 19, 2016
    3 Tips for Preserving Your Submersible Well Pump

    Water is necessary for all living things; however, it can have a damaging impact on mechanical equipment.  Below, we have listed three tips for preserving your submersible well pump to ensure it runs efficiently for the lifetime of the pump.

    1. Prevent multiple starts- You can extend the life of your well pump by preventing the number of multiple start-ups, also called short cycling.  It is better to allow the pump to turn on and stay running continuously instead of having the pump turn on and off frequently.  Frequent starting and shopping can cause the windings in the motor to overheat causing the motor will wear out faster than it should.

    2. Pressure Switch - Frequently check and clean the pressure switch.  The switch can become easily corroded and packed with small ants and bugs.  Regular maintenance performed on the switch will prevent replacement.  A good water pressure to adjust the switch to should be between 40-60 psi.

    3. Bladder Tank - Checking the air pressure in the bladder tank is something that is frequently overlooked by well owners, mostly because people simply do not know to include this as a part of their regular maintenance.  The air pressure in the bladder tank should be checked every year.  To perform the check, fist turn off all power to the submersible well pump.  Allow the water to drain by running the faucet.  Then, by using a tire gauge, check the air pressure at the top of the bladder tank located by the air nipple.  A good air pressure should be about 38 psi (or 2 psi below the cut-in pressure).  

    Above we have detailed three easy ways to prolong the life of your submersible well pump through regular preventative maintenance and inspection.  If ever you have a question or need an option on your submersible well pump, the experts at W. P. Law, Inc will be sure to help. 

    How Can Irrigation Help Protect My Crops From Frost?

    WP Law - Thursday, December 15, 2016
    Crops in the frost

    Temperatures are dropping here in South Carolina, which means one of the biggest dangers to our precious crops is frost. The freezing cold conditions that create frost cause ice to form inside plant tissues. As we all know, water expands as it freezes into ice, so this expansion within a plant can cause its cell membranes to burst. This is physically damaging to a plant and can result in its death.

    Clearly, frost is not good when it comes to keeping your crops alive and healthy. Irrigation methods, such as sprinkler systems, can help prevent frost from hurting your crops.

    The Science Behind Frost Prevention

    The method by which irrigation saves crops from frost is actually quite simple. Water is sprayed on the plants, covering the exterior of the crops. The water freezes in the cold weather, and in the process the heat inside the water is released and transfers to the plant, keeping its temperature from dropping below 32°F.
    However, the ice that forms on the outside of the plant has to remain wet in order for the plant to stay at the freezing point. This is because if no more water is added to the ice, its temperature will drop below freezing and no more heat will be transferred to the plant, allowing its internal temperature to drop below freezing, as well. As long as water is added to the ice, the mixture of ice and water will remain at 32°F and will keep the plant’s temperature from dropping any further.

    3 Benefits to PVC Tubing

    WP Law - Monday, December 12, 2016
    PVC Pipes

    PVC piping provides reliable service for contractors and farmers in a variety of industries. With many advantages, it is easy to see why PVC pipe has replaced traditional materials for many projects.

    Convenient Design

    PVC pipes are generally much lighter than other materials used to create pipes. A lightweight design is easier to maneuver, preventing injury and reducing the number of people it takes to move equipment. PVC pipes are also highly flexible, which makes them resistant to breakage and generally more durable than other materials.


    Because PVC pipes are made of non-toxic materials, they are generally safer to use. A significant amount of research has gone into testing PVC pipe materials for overall safety and quality.


    PVC pipes are durable and offer more options when it comes to design and use. Many farmers and contractors use PVC to refurbish existing systems for even greater versatility.

    W.P. Law, Inc. is an industry leader in the Southeast when it comes to supplying irrigation equipment to farmers and contractors. Contact the experts at W.P. Law today for the answers to any additional questions you may have about the benefits of PVC tubing.

    Learn more about the USDA, NRCS, EQIP, and TSP

    WP Law - Thursday, November 10, 2016

    The Role of the USDA:
    The U.S. Department of Agriculture (USDA) is a cabinet-level agency that oversees the American farming industry. USDA duties range from helping farmers with price support subsidies, to inspecting food to ensure the safety of the American public.

    The Role of the NRCS:

    The Natural Resources Conservation Service (NRCS), formerly known as the Soil Conservation Service (SCS), is an agency of the United States Department of Agriculture (USDA) that provides technical assistance to farmers and other private landowners and managers.

    The Role of the Technical Service Provider or TSP:

    Technical Service Providers (TSPs) are individuals or businesses that have technical expertise in conservation planning and design for a variety of conservation activities. TSPs are hired by farmers, ranchers, private businesses, nonprofit organizations, or public agencies to provide these services on behalf of the Natural Resources Conservation Service (NRCS).  Each certified TSP is listed on the NRCS TSP online registry, TechReg.  The TSP registration and approval process involves required training and verification of essential education, knowledge, skills and abilities.

    What is the Purpose of the EQIP Programs?

    EQIP is an acronym for Environmental Quality Improvement Program. Via these programs agricultural producers are provided financial and technical assistance to in order to address natural resource concerns and deliver environmental benefits such as improved water and air quality, conserved ground and surface water, reduced soil erosion and sedimentation or improved or created wildlife habitat.

    Relationship of TSP and Irrigation Water Management Plan portion of EQIP:

    In 2013, the South Carolina NRCS mandated that Irrigators that were applying for EQIP Funds must also provide NRCS an Irrigation Water Management Plan (IWMP) prepared by a TSP to qualify for funding. Prior to 2013 and with just a few documents, irrigation plans and water management plans could be generated by a Professional Engineer (PE) or an Irrigation Association (IA) Certified Irrigation Designer (CID). Today’s IWMP is a much more comprehensive document including examining many facets of the irrigation design and water management process.

    A partial list of elements to be included in the plan is as follows:

    1. Identify the Resource to be Managed and Conservation Practice to be applied using good Economic Practices and Management Schemes.
    2. Crop Type & Rotation
    3. Maps of Field & Water Delivery System including Emission Devices.
    4. Documentation of Past and expected Future withdrawals of Water.
    5. Volumes of water to be applied over the growing Season
    6. Soil Test for nutrient Levels, Soil Type and description of Soil Horizons
    7. Test water for Irrigation Suitability including P, K, Ca, Mg, Na, Fe, Cu, B, Cl, EC, Sulfate, Nitrate-Nitrogen, pH, Carbonate, TDS and SAR.
    8. Estimates of Distribution Uniformity of irrigation System
    9. Develop an Irrigation Schedule – When to Irrigate & how much to Irrigate based on existing level of soil moisture.
    10. Develop an Operation & Maintenance Manual for the Irrigation System.

    What Can I Learn from A Pipe Stress Test?

    WP Law - Thursday, November 03, 2016
    pipe leak

    Periodically industries and municipalities will conduct pipe stress tests.  The purpose of these tests is to make certain that the piping system, which includes gaskets, valves, and fittings do not leak and maintain an acceptable level of safety.  These tests are often required by law: both the timing of the tests and the stresses the pipes are put under.  When laws do not set parameters for pipe stress tests, there should be policies that determine when and at what level the tests should occur.
    As any piping system is used, and as it ages, leaks or other mechanical problems can arise which left unnoticed can eventually cause bigger problems.  A pipe stress test is a way to ensure leaks do not exist, and to fix them if the tests indicate leaks are present.  Similarly, when pipes are placed under additional and unusual pressure, they may move which can likewise lead to leakage.  Testing the pipes under unusual pressure can help detect where movement is likely to occur and limit the danger from this occurring. 

    What Can Cause Pipe Stresses?

    Stresses can come from:
    • Additional weight
    • Temperature changes
    • Changes in pressure in the pipe
    • Changes in external pressure
    • Vibration
    • Wind, seismic shifts, and other acts

    Stresses can be caused by sustained loads such as pressure and weight and they are in existence throughout the life of the pipe.  Pipe stress tests are looking for places in the piping system that might fail when the pipes are put in unusual situations—greater pressure than normal, sudden wind sheers, earthquakes—to determine if repairs need to be made before leakage occurs during the course of operation.

    Common Examples

    Gas and oil pipelines are tested by increasing the pressure to a minimum of 125% of the maximum allowed working pressure.  Often the amount of pressure to be used in a pipe stress test is determined by law.  The test pressure is higher than the pressure used during common operation.  The pipes are often filled with dyed water or oil so leaks can be easily spotted.  The pipes are then pressurized for 30 seconds or more, and the expansion of the pipes is measured. 
    If a leak does happen, testers will determine if the problem was due to a failure of the pipe itself or due to a poor seal of the test equipment.  Leaks are not the only way to determine if a pipe is inclined to fail.  Changes in length or diameter also indicate a pipe may not be safe.

    If you suspect your pipe system is in need of replacement or repair parts, contact WP Law today.

    Why doesn't my traveling irrigation system maintain consistent pressure as it moves?

    WP Law - Thursday, October 13, 2016
    sprinkler system

    A traveling irrigation system can be the easiest way to evenly irrigate crops, sports fields or other large, flat areas. Often, however, the system fails to maintain the same water pressure as it moves, and does not distribute water evenly. Why is this?


    A sprinkler system that is operating loses pressure through friction - a loss which has to be calculated when the system is designed. Because the primary loss of pressure is due to friction, the further the water has to travel, the more pressure is lost. Selecting the proper pipe size based on the flow rate of the system is an important design element.


    If you are operating a sprinkler system on uneven ground, then any change in elevation is going to make the distribution of water pressure uneven. Pipes should be, as much as possible, laid across the slope rather than up and down it.

    Compensating for these factors

    A well designed system will compensate for this and ensure that you get the design pressure needed at heads furthest from the source or when the traveling system is furthest away.
    To get even irrigation requires a certain expertise in system design. W.P. Law, Inc. is experienced in irrigation systems of all sizes, from small residential applications to farms and sports facilities. Contact them to find out what how to get even irrigation and no brown spots.

    Know These 10 Benefits of Using Effluent Spray Systems On Your Farm

    WP Law - Thursday, September 08, 2016
    effluent sprayer in a field

    Good effluent management is made up of a mix of having a good system in place, the best processes to use that system, and assurance that the effluence is being applied at the right time in the right place. Here are 10 key benefits of using effluent spray system on your farm.

    1. Savings on Fertilizer

    When you use an effluent spray system, you save on fertilizer expense. An effluent spray system enables you to utilize the inherent nutrients in the effluent rather than lose that nutrient value to waste.

    2. Application Control

    Effluent spray systems provide built-in capabilities to control application saturation. Farmers can mathematically calculate the intensity of the application according to variances such as soil moisture, condition, and topography.

    3. Environmental Compliance

    With an effluent spray system, farm owners can provide proof of environmental compliance with data such as application region, usage, and output.

    4. Better Ground Coverage

    Effluent spray systems allow operators to cover more ground faster than other methods of effluent application.

    5. Measurable Results

    Effluent spray systems should have flow meters so that farm owners know exactly how much effluent is being sprayed, at what pressure, and for how long.

    6. More Efficient Labor

    Time is always in short supply on a farm. Automated effluent spray systems free up man power so they can take care of other tasks on the farm.

    7. Less Storage Needed

    With a properly designed and operated effluent spray system less lagoon storage may be required.

    8. Fewer Moving Parts

    Effluent spray systems are very simple and have few components to give trouble. Effluent sprinklers are designed for the rough service that they face. The same is true with the valves and pumps used in these systems.

    9. Easy to Add-on to the System

    Effluent spray systems can be broken up into zones to allow flexibility in application rates. Adding additional zones as your operation grows is very easy to do.

    10. Easy To Manage In Rough Or Rolling Terrain

    Effluent spray systems can easily apply waste to uneven terrain. Tanker trucks and spray wagons do not perform well on difficult terrain. Tip-over can be a concern in the most extreme cases. Not this is an issue with a solid-set effluent spray system.

    What are you waiting for? If you are seeking an effluent solution, contact the experts in fluid handling equipment at W.P. Law. Whether you need more information about effluent spray systems, or any other fluid handling system, chances are we’ve got the solution for you!

    What Are the Advantages of Using Subsurface Irrigation (SDI) on Crops?

    WP Law - Thursday, August 11, 2016
    Rows of crops in a field

    Both indoor and outdoor farming can benefit from the use of subsurface irrigation systems. These systems are highly customizable to nearly any need. They are on average less expensive and offer an outstanding level of reliability when properly installed compared to more traditional overhead irrigation methods. But, why should a commercial farmer make the switch to this form of irrigation over other methods?

    Key Advantages Are Hard to Overlook

    Subsurface irrigation is growing in importance today. It provides numerous opportunities for large scale and small growers alike. Take a look at some of the reported benefits of subirrigation systems:

    • There is an immediate reduction in costs simply because there is no need for a worker to water plants since the subirrigation waters automatically. 

    • It costs less to water plants more fully. Less water is lost in the process and there’s no run-off.

    • Subsurface irrigation systems can free up aboveground space. This can increase the amount of crops produced and less equipment required. 

    • Crops grown in these conditions may grow more uniformly. The water is evenly distributed across all plants, improving overall growth level. More so, there is less of a need for fertilizer use, which is both good for the environment and for budgeting.

    • With less water remaining on the leaves, there is a lowered risk of excessive moisture damage.

    In addition to these benefits, subsurface irrigation can be an eco-friendly move. It allows growers to better manage resources and reduces overall mechanical use. Additionally, the use of these systems can help to reduce the need for fertilizer. Used within a greenhouse or outdoors, subsurface irrigation is not complex but it does require a properly designed system for the unique aspects of the project. Overall, subsurface irrigation provides a clear opportunity for most applications.

    5 Best Applications for Drip Irrigation Systems

    WP Law - Thursday, July 14, 2016

    Do you have tree or vine crops? Do you own agricultural land in an area with large amounts of sunshine? If you answered "yes" to either of these questions, then you should consider using a drip irrigation system to more effectively water your crops.

    The Benefits Of Drip Irrigation Systems

    Recent studies show that a properly designed drip system can use between 30 - 50 percent less water than traditional watering methods, such as sprinklers. The reason that a drip irrigation system is so effective is that it delivers water directly to the plant's root zone. This slow delivery allows the plants to absorb the water one drop at a time, which reduces runoff and evaporation. In addition to the roots absorbing the precious water, the soil surrounding the roots is gradually soaked, so that the plants can acquire more water as they need it throughout the day.

    One of the final benefits of a drip irrigation system is that leafy plants are not at risk for burning. The sun is more likely to burn crops when traditional watering methods are used on leafy plants. For example, if a sprinkler is used to water grape vines, then the water could sit on the leaves during the hottest part of the day. If that occurs, then the fragile grape leaves can shrivel and turn brown in the scorching sun. A drip irrigation system avoids burning the leaves by dispensing water directly into the root zone and away from the plant's leaves.

    5 Uses For Drip Irrigation Systems

    Drip irrigation systems can be used on a wide variety of plants, including:

    1. Low-growing crops, such as: bell peppers, lettuce, beans, and squash;
    2. Grape vines, olive trees, and orchards on irregular landscapes;
    3. Fruits, including: blackberries, strawberries, and blueberries;
    4. Staple crops, such as cotton;
    5. Crops that grow just below the surface in the soil, such as: potatoes, onions, and carrots.

    It's easy to see that not only do drip irrigation systems have a multitude of benefits, but they also have a wide number of agricultural applications.

    7 Ways To Reuse Wastewater In Your Facility

    WP Law - Friday, July 08, 2016

    As the demand for clean water rises with growing populations, industrial facilities are seeking new ways to use this valuable resource. Did you know that recycling wastewater is an innovative resource with financial savings? Reclaimed water offers a number of benefits and costs less to produce than treating water for drinking. See how your facility can experience these benefits below.

    1. Industrial Use

    Reclaimed wastewater can directly benefit industrial plants in several ways, such as reuse for cooling, boiler feed, and industrial processes. 

    2. Toilet Flushing

    Though odd sounding at first, reclaimed wastewater for toilets is a growing trend in public restrooms and high-rise buildings across the United States. Evidence shows that reclaimed toilet water offers significant financial savings. Industrial plants may also benefit from this in their own restrooms.

    3. Landscape and Agricultural Irrigation

    The nutrient content in recycled wastewater can be very beneficial for landscaping and agriculture. You may not even need to use as many fertilizer treatments. Consider using this valuable resource to irrigate any landscaping around your industrial plant or commercial development. This simple method of wastewater use cuts costs and helps the environment.

    4. Revenue

    Recycled wastewater can also be used to generate revenue. Industrial plants can transform sewage into a commodity that can be used or sold to other facilities, such as public parks and agricultural institutions.

    5. Create and Enhance Wetlands

    Did you know that recycled wastewater can reinforce sensitive wetland ecosystems? It's true! Supplementing wetlands with recycled water is an excellent way to manage wastewater effluent without harming the environment. Several towns in the United States, such as Incline Village, Nevada, have done this with success. This creative use of wastewater also aids wildlife and educates communities.

    6. Golf Course Irrigation

    Providing recycled wastewater to golf courses solves common environmental problems in the golfing industry, such as drought. This practice has been used for decades and some golf courses use recycled water for all of their irrigation.

    7. Artificial Lakes

    Industrial plants can recycle excess wastewater and use it to create artificial lakes. Several existing artificial lakes benefit the environment and have become homes for thousands of wildlife species. Recycled wastewater can also replenish groundwater reservoirs and prevent saltwater intrusion.

    Curious to learn how recycled wastewater can benefit your industrial plant? W.P. Law can help. Our skilled fluid handling professionals specialize in saving energy and reducing costs for your success.

    How Can I Effectively Irrigate Many Different Crops At Once?

    WP Law - Thursday, June 09, 2016
    Agricultural Irrigation

    Whether your farming operation is large or small, it is important to make sure all the plants in your field have adequate water regardless of what’s going on with the weather. That is why an effective irrigation system is so important.

    The ability to get water to many different crops at the same time will save you a great deal of time – and your farm a great deal of money and frustration. But, how you do so effectively without placing some or all of your crops at risk?

    Irrigation Pumping

    When it comes to agricultural irrigation there is one phrase you need to know: variable speed drives. This refers to the pumps that move the water used in irrigation. Traditionally, pumping water for irrigation is a costly endeavor – costing the U.S. approximately 15.5 billion dollars in energy alone per year according to the USDA Natural Resources Conservation Service.

    Variable speed pumps are more energy efficient because they don’t operate continuously at the highest possible pump speed.

    How do Variable Speed Pumps Benefit Farmers Who are Irrigating their Crops?

    Crop irrigation is important for South Carolina farmers. These are a few benefits variable speed pumps introduce into the picture.

    1. It saves a great deal of money on energy bills. According to NSW Farmers, reducing the pump motor speed by as little as 20 percent can net energy savings of up to 50 percent. Over a farming season that can be a substantial amount of money for small farms. Larger farms stand to save even more.
    2. A Variable speed drive allows for a pump to be used for multiple applications.
    3. The grower has increased flexibility in their irrigation scheduling.

    Irrigation can be a tricky matter. Go to the experts at W.P. Law, Inc. whenever you have questions or concerns about your current irrigation methods or equipment. They’ll answer your questions and help you solve your irrigation problems.

    What can cause a pump shaft to break?

    WP Law - Thursday, May 19, 2016
    pump systems

    The pump shaft is the central piece that connects the pump’s impeller to the driver (electric motor, engine, etc.) A broken or cracked pump shaft is a catastrophic failure that is often the result (or cause) of significant pump damage.

    Troubleshooting Your Pump Shaft

    A number of things can go wrong and cause your pump shaft to crack or break. Three of the most common of these include:

    1. Damage to the pump’s impeller. A damaged pump impeller can cause imbalance and vibration that puts more stress on the pump shaft. This imbalance can cause excessive wear on the pump bearings allowing the shaft to move laterally causing the shaft to flex and eventually fail.
    2. Worn Bearings. As mentioned above, bearing failure can lead to pump shaft failure if not addressed early. The pump shaft should be checked periodically for any lateral movement in the pump shaft. Bearings that are worn usually cause the pump to run louder than normal and can also cause the pump to draw more current that normal.
    3. Misalignment. Pumps that are belt driven or use a flexible coupling can become misaligned. Misalignment puts additional stress on the pump’s bearings and shaft. Belts that are over tensioned can also cause excessive stress on the pump shaft leading to failure.

    To learn more about how to keep your pump well maintained and running smoothly, contact W.P. Law, Inc. today. We've been helping North and South Carolina farmers and homeowners with their irrigation needs since 1970.

    Best irrigation systems for irregularly shaped fields

    WP Law - Thursday, May 12, 2016
    agricultural irrigation systems

    In most cases, the most popular overhead irrigation system is the center pivot system. This consists of a pivot, often serviced by a well in the middle of the field, with several sprinklers rotating from it. Ideal for covering large evenly dimensioned fields. However, they are not perfect for small or irregular fields. Luckily, there are other options:

    The Traveler (Traveling Gun)

    Traveling gun sprinkler systems typically feature a large “big gun” sprinkler on a movable cart. Water is supplied to the cart by a HDPE hose. As water is pumped through the hose to the sprinkler the hose is wound around a large hose reel. As the hose winds around the reel it moves the cart across the field. Travelers are ideal for irregularly shaped fields and areas that only need intermittent irrigation. Traveling guns can also be moved from field to field as irrigation needs change throughout the growing season.

    Drip & Micro Irrigation Systems

    Drip and micro irrigation systems irrigation can be an extremely effective way to water an odd shaped field. Pressure compensating emitters allow for varying row lengths and slight elevation changes. Drip irrigation systems allow for water to be placed near the root zone greatly lowering losses to evaporation and improving system efficiency.

    Ultimately, the right choice depends on the shape of your field, the type of crops you are growing, your access to labor and several other factors. Want to learn more about which irrigation strategy is best for your needs? Contact W.P. Law today to chat with one of our company's specialists.

    Beware of these 3 things that can cause failure in your piping system

    WP Law - Thursday, May 05, 2016
    irrigation piping system and root

    If you use an underground irrigation system for your lawn, garden, farm or nursery, you know how invaluable such a system can be in getting the right amount of water to the plants at just the right times. However, like any mechanical system, irrigation systems are occasionally subject to break-downs and pipes getting broken or clogged. The good news is that you can help prevent such problems if you know the things to look out for.

    Things To Watch Out For With Your Irrigation System

    1. Tree roots. If one of more of your irrigation heads is not functioning well or at all, it likely is being hampered or crushed by growing tree roots. This is a particular problem during the spring growing season as tree roots seek the largest source of water. You can help prevent this from happening by not locating your sprinkler heads between large trees and water mains.
    2. Poor installation. Another common reason for pipe failure is that the system was not installed correctly. While you can save some money by installing the system yourself, this may not save you money in the long run.
    3. Too much water pressure. Too much water pressure can cause valves and sprinkler heads to wear out faster than normal. It's important to set the water pressure at the correct pounds per square inch (psi) as recommended by the manufacturer.

    Don't wait for your irrigation system to fail. Watch out for tree roots, make sure that your system is property installed and that the water pressure is set correctly. To learn more about keeping your irrigation and sprinkler systems running smoothly all season, contact W.P. Law, Inc. today.

    4 Tips To Find An Energy Efficient Pump

    WP Law - Thursday, April 21, 2016

    When selecting a pump for your agricultural, industrial, or residential irrigation needs the details matter. Today, it is more important than ever to focus on an energy efficient solution to your pumping needs. There are solutions available to fit just about any application. So before you head out to buy a new pump take these tips into consideration.

    #1: Get the fitting just right

    A common mistake when it comes to pump installation is choosing one that will “probably do the job." Instead, invest the time to ensure you have a pump that fits your specific application. It sounds simplistic, but choosing a pump that is properly selected and sized for your application, will help to naturally reduce the amount of energy required to operate it.

    #2: Consider other system components

    The pump might be the heart of the system, but other components in the piping system have an effect on the pump size and operation. Improperly sized components such as piping, control valves, and suction strainers can create high friction loss values that require a larger pump. Of course a larger pump means higher energy costs. Having properly sized system components can mean big savings over the life of the system.

    #3: Compare features

    One common misconception is that all pumps are created equal. Many customers mistakenly assume that one 5 horsepower pump is as good as any other 5 horsepower pump. Not true. There can be a wide range of pumping efficiencies between pump models and manufacturers. The type of pump you select can also have an impact on the pumping efficiencies.

    #4: Don't over buy

    Bigger is not always better. A pump that is properly sized for your application is always best. However, if you know your system will be expanding in the near future this can be taken into account in the initial sizing process. Control accessories such as a variable frequency drive (VFD) can be used to run the pump at a more efficient operating point on the pump curve. VFD’s are also useful at controlling energy costs when the system has a wide range of flow and pressure requirements.

    The good news is you don't have to go it alone. With the help of the team at W. P. Law, Inc. you can find an energy efficient pump designed just for your application. Let us help you today.

    5 Factors to Consider When Choosing an Irrigation System

    WP Law - Thursday, April 14, 2016
    Designing an irrigation system

    Human society as we know it could not exist without irrigated land. For more than 2,000 years farmers have used irrigation to grow food for hungry populations. This does not mean that all irrigation methods are equally useful, however. Knowing which approach will work best in your situation requires knowing something about the options available, including the advantages and disadvantages of each. With that in mind, here is a look at five things to consider in getting water to your crops:

    1. Soil type. The type of soil in an area can affect not only the type irrigation method used but also the irrigation run times. Sandy soils typically require frequent applications of water at a high rate to keep moisture in the root zone. Tighter clay soils can hold moisture longer that sandy soils, but may require frequent applications at a lower rate to prevent runoff.
    2. Land topography. In particular, hilly or sloping land can be a challenge. Drip irrigation works well if the laterals can be run along topographic lines. System run times may need to be adjusted to prevent runoff. Travelers and center pivot systems are usually out of the question on hilly and severely sloping land.
    3. Local weather patterns. For example, sprinklers are less desirable in areas where high winds are common and in arid areas with a low humidity since water losses due to evaporation can be extremely high. Drip irrigation works well in both of these situations.
    4. Type of crops grown. Sprinkler and drip systems can require high levels of investment. For this reason, it’s better to reserve their use for high-value crops like vegetables, small fruits and orchard crops rather than applying them to commodity crops like wheat and soybeans.
    5. Water quality. All drip irrigation systems require some type of filtration. Overhead systems such as sprinklers seldom require filtration. Irrigation water should be tested for water borne pathogens. Depending on the crop grown and irrigation method used chlorine injection may be required. Other water quality issues that may be of a concern include levels of soluble iron and other dissolved minerals.

    We hope this article has given you some useful insights into selecting the right irrigation method for your operation. Contact us today to find out more.

    Where should I use drip irrigation systems?

    WP Law - Thursday, March 24, 2016
    Drip Irrigation Pipes

    What Is Drip Irrigation?

    Drip irrigation waters plants literally one drop at a time. Sometimes the delivery mechanism runs across the open ground. Other times it’s buried underneath the soil. In either case, all drip irrigation systems contain three essential features:

    1. A pressurized source that maintains consistent water delivery. This can be a pump or simply a gravity-fed, graded layout.
    2. Tubing or pipe with small emission devices to control the release of water.
    3. Some type of filtration mechanism to keep dirt and debris out of the system.

    This last feature points out one of the primary challenges of using drip irrigation: the need for effective filtration. Even a small amount of dirt or other contaminant can clog up the works, starving plants of needed nourishment.

    Distributing fertilizer is another challenge when using drip irrigation. Traditional granular fertilizing agents can be applied prior to planting. Drip grade liquid fertilizers are available for injection into the drip irrigation system and can be used as supplements to the granular fertilizer.

    So, should you use drip irrigation or not? The answer to this question depends on multiple factors. Here are six pros and cons of the method to help you make an informed decision.


    1. Drip irrigation is far more efficient than traditional methods. This makes it ideal for locations in which limited water is available for agricultural use.
    2. Drip irrigation can use partially treated wastewater, removing the need to make it potable first.
    3. Drip irrigation allows growers to fine-tune their watering methods to the unique characteristics of their soil, growing season, and other variables.


    1. Depending on the field layout, size, and elevation changes, drip irrigation systems can be complex and expensive to install.
    2. As mentioned before, effective filtration is essential to prevent drip irrigation systems from clogging.
    3. Because the grower never sees the water being delivered to the root systems, he or she must monitor plant health and growth carefully to ensure adequate hydration.

    How Will an Irrigation System Help Me Conserve Water?

    WP Law - Thursday, February 25, 2016
    Agricultural Irrigation System

    It is a simple fact of life: every living organism requires water for survival. As professional landscape contractors and farmers, you want your plants to do more than merely survive; you do everything you can to encourage them to thrive! Hand-watering plants is a labor and water intensive endeavor. An automated irrigation system actually conserves water and saves money on labor costs.

    Tips For Conserving Water With Irrigation System Automation

    1. Concentrate watering efforts where you need them the most. With an automated irrigation system, your property will be divided into zones with different water requirements. Ornamental plants, trees, turf, hillsides, sunny areas and shady areas all have different water requirements. With an automated system, your property is divided into zones and irrigation is scheduled according to need. For example, your sunny zones will get more water than your shaded ones.
    2. Water plants at the optimal time of day. Evaporation is the enemy of efficient watering. While it is more convenient to water plants in the daytime, you are guaranteed to lose some of that valuable water to evaporation. With an automated system, you can water your plants in the early morning hours before either you or the sun is out of bed.
    3. Automatic shutoffs will prevent over watering during a rain event. Ever see a sprinkler system running on an especially soggy, rainy day? You should not. All irrigation systems should have an automatic rain shut-off device installed. In some states is required by law to a have rain sensor installed on your irrigation system. These sensors should detect when a specific amount of rain has fallen and override the automated schedule to conserve water, alleviating any concern you might have about over watering your plants.

    Take These 4 Things Into Account When Choosing Your Farm Irrigation System

    WP Law - Thursday, February 11, 2016
    Farm Irrigation Sprayer

    If you're in the market for a new farm irrigation system, it can be overwhelming trying to decide what system is the best match for your land, your crops and your budget. Even seasoned farmers can be confused by all of the new irrigation technology. Before you go shopping or meet with an irrigation contractor, it's good to consider a few basic questions.

    What to consider when choosing a farm irrigation system

    1. What type of system is best for your land, your crops and your budget? There are two basic types of farm irrigation systems--overhead irrigation and drip/micro irrigation. Overhead irrigation systems apply water above the crop using sprinklers, big guns, travelers (traveling guns) or center pivots. Drip/Micro-irrigation systems release water at ground or below ground level, directly to the plants. Drip/Micro-irrigation systems are a good choice for very hot climates where the water will evaporate quickly and for plants that are prone to fungi and diseases aided by water on the leaves.
    2. Your water source. Do you have an adequate water source to supply your irrigation system? Water sources include wells, ponds, lakes, streams, and canals.
    3. The lay of the land. The shape of the field and the topography are also considerations when choosing the type of irrigation system you will purchase.
    4. Manpower. Do you have the workers necessary to maintain and operate your irrigation system? Irrigation systems can be automated in a number of ways to make the operation and management of your system easy.

    3 Benefits of Variable Speed Pumps in Agricultural Irrigation

    WP Law - Monday, January 18, 2016
    Agricultural Irrigation Design

    When it comes to agriculture there are about a million different products and items that are used from day to day and one is an agricultural irrigation pump. There are many types of pump but one that is gaining in popularity it the variable speed agricultural irrigation pump. There are plenty of reasons that this pump is easy to use and great for many different purposes. Here are three benefits of this type of pump.

    1. Irrigation System Flexibility- Agricultural irrigation systems are typically zoned by field size, crop type and/or crop maturation date. In many cases this type of zoning can lead to zones of widely different flow rates, especially when a grower may have several small or irregularly shaped fields. In the past the solution to this problem is to size the pump for the worst possible case and then try to come up with some combination of valves to get the pump to operate at the best efficiency point. Invariably there is always a zone or two where the pump is way oversized for the application. This can cause unnecessary wear and tear on the irrigation system and cause higher energy consumption and costs. The Variable Frequency Drive (VFD) allows the pump to be run at a lower speed thus reducing the pump’s performance. The advantage of the VFD is that you can customize the way your irrigation systems runs by changing the pump’s speed of rotation. This means a smaller zone can be run and the system will slow the pump down thus reducing the flow and pressure to deliver exactly what is needed to operate the smaller zone. This can provide a huge energy savings over the course of the growing season.
    2. Water Conservation- Variable Frequency Drives (VFD’s) also help in conserving our planets most valuable resource. VFD’s conserve water by operating irrigation sprinklers at the optimum pressure. Over pressurized sprinklers tend to “fog” or mist as the higher pressure creates smaller water droplets through the sprinkler’s nozzle. These smaller droplets are more susceptible to movement by wind and are more easily evaporated into the atmosphere. Water that evaporates before it hits the ground is obviously of no use to the plant.
    3. Several Pumps In One- It used to be that irrigation pump stations consisted of a small “jockey” or pressure maintenance pump and one or more main pumps. The pump station control system turned pumps on and off depending on the flow rate required by the system at the time. The VFD essentially eliminates the need for the small jockey or PM pump. With a VFD now one of the larger pumps can serve as the jockey or PM pump to provide water to the system when the pressure and flow rate requirements are, but it can also step up and deliver higher flows and higher pressure when the system demand dictates

    These are all great reasons to think about investing in a variable speed agricultural irrigation pump. If you need more help on the subject, you can always contact the experts at W.P. Law, Inc.

    What Steps can I Take to Protect my Crops from Frost?

    WP Law - Thursday, December 10, 2015

    As the temperatures begin to dip throughout most of the country, and "chilly" instead of "balmy" is used to describe the night air, you need to start thinking about protecting your crops from frost. Frost can easily injure plants by causing ice crystals to form within the plant cells. When these crystals form, water becomes unavailable to the plant tissues, which causes the leaves to appear to be water-soaked, shriveled, brown, or black. To help you protect your crops from frost during the late fall season, we have gathered together a few helpful tips.

    4 Tips To Protect Crops From Frost

    1. Covering your crops. -- Small acreage, low-growing commercial crops can easily be covered with straw mulch, plastic, tar paper, or reemay cloth to protect them from frost. These coverings work to reduce the heat loss from the ground and plant's surface, and, in doing so, protect the crops from the drop in nightly temperatures. Covers should be removed during the day when the sun is out.
    2. Fog clouds. -- Using fog clouds can help farmers protect their crops from frost. The fog reduces the amount of radiative heat loss from the surface. However, it is difficult to maintain the correct fog coverage across all crops; as such, this is an effective but less reliable method to protect crops from the harsh effects of frost.
    3. Water correctly. -- The right watering tactics can be used to protect crops during a night frost. The soil should be thoroughly watered during the day. The wetter soil will hold the heat better than the dry soil, which will protect the crops' roots and keep the surface temperature from dropping too low. The appropriate irrigation system can help you to more easily water your crops based on the predicted nightly temperature.
    4. Use heat lamps. -- On small acreage farms, 100-watt lamps can be used to emit warmth and reduce frost damage. If possible, cluster container plants together underneath the lamp. If the plants or crops cannot be transplanted, then hang the heat lamps, so that their rays cover a larger area.

    With these tips at the ready, you will be able to actively protect your crops from frost. Do you need help finding the right tools to protect your crops? Do you want to learn additional tips? If so, contact an expert at W.P. Law, Inc. Since 1979, W.P. Law has been helping farmers protect their crops throughout all seasons and temperature changes.

    What Are Signs That My Actuator Valve Is Not Working Correctly?

    WP Law - Wednesday, November 25, 2015
    Actuator Valve

    With the proper prevention and maintenance techniques, irrigation valves are highly reliable and can last for years. With this in mind, valves can become difficult to troubleshoot, due to the numerous amount of parts that might be causing the problem or malfunction. By learning how the irrigation valve works, you can be better prepared to troubleshoot almost any problem.

    Understanding The Importance Of An Actuator Valve

    An actuator valve is often powered by a motor. The motor is used to convert electrical energy into a mechanical torque. Once the desired level of torque is acquired, the valve is then opened or closed. When used within an irrigation system, the actuator valve is often one of the highest operating valves. With this structure in mind, troubleshooting an actuator valve malfunction often starts with one of the following symptoms.

    • Water is not running from one end of the irrigation system to the other.
    • Flooding is occurring due to built-up pressure.
    • Water pressure is not at the correct levels.
    • Debris or other contaminants are showing-up in the water.
    • Loud noises, such as hissing or clanking sounds, are being emitted from the valve.
    • The actuator valve is not opening or closing completely.

    If you have noticed any of the above symptoms, then your actuator valve might not be functioning properly. To help you further troubleshoot the malfunction, we have gathered together a few potential causes and solutions.

    • Check the electrical signal to the valve. -- If the electrical signal (voltage) is too low, then the actuator valve will have difficulty opening and closing. A volt-ohm meter can be used to check the voltage between the irrigation controller station terminal and the ground. Review your manual to determine what the appropriate voltage reading; and carefully make adjustments as needed.
    • Check for valve contamination. -- A valve's direct connection to the main water line can make it more susceptible to contamination from debris, dirt, or contents within non-potable water. To help reduce the risks of contamination, install a filter to keep contaminants away from the valve.
    • Clean the screen or filter. -- If you have installed a filter to protect your valve from contaminants, then you need to clean it on a regular basis. Failing to clean the protective filter or screen can result in a malfunctioning valve.
    • Thoroughly inspect the valve for damage. -- Check for loose parts, dents in the valve, and other signs of wear-and-tear. If your valve is damaged, then it won't be able to properly function. Carefully replace all damaged parts or the entire valve to resolve the issue.

    With these helpful tips in mind, you will be able to properly troubleshoot your actuator valve malfunction. For further help, contact a member of W.P. Law. The entire team is dedicated to providing valuable insights and products to help companies achieve their irrigation goals.

    How Do I Prepare My Farm Irrigation System For Winter?

    WP Law - Thursday, November 12, 2015
    Agricultural Irrigation System

    Once the growing season is over and the harvest has been completed, it will be time for the winter winds to come howling onto your farm. Don't be caught unprepared; make sure that your farm irrigation system is properly prepared for the winter. From insulating assets to protecting your valves, we have four crucial tips to help you winterize your large-scale irrigation system.

    4 Tips To Successfully Prepare Farm Irrigation Systems For Winter

    Before the first frost and well before the snow begins to fall, you should take the time to properly winterize your farm's irrigation system. Failing to winterize your irrigation system can result in frozen pipes and broken equipment.

    Tip #1. Insulate Your Assets

    The farm irrigation winterization process starts by shutting off the outdoor water supply. Next, you should protect the main shut off valve from the soon-to-be below freezing temperatures. One of the easiest ways to protect the main shut off valve is through insulation. In addition to insulating the main shut off valve, you will need to insulate any above ground piping. Before you apply the insulating tubes of self-sticking foam insulating tape, make sure that all of the water has been drained from the pipes. If water is left in the pipes, then they might freeze or burst during freezing temperatures.

    Tip #2. Drain Any Pipes

    As mentioned in the preceding tip, make sure that you drain any and all outdoor pipes that will not be used during the winter. Water can easily expand and freeze during extreme temperatures. If the water is left in your pipes, then regardless of insulation, they could freeze and burst. To drain your pipes use an automatic or manual drain valve. Take the extra time needed to drain any long, industrial watering hoses before storing them for the winter.

    Tip #3. Protect Valves and Backflow Preventers

    Make sure that your backflow preventers and all above ground valves have been properly insulated. The air vents and rain outlets on the backflow preventers should not be blocked by insulation. Insulation foam or tape can and should be used on these parts.

    Tip #4. Store Any Large Pieces of Equipment Indoors

    Whenever possible, your large pieces of farm irrigation equipment should be safely moved indoors. Subjecting your irrigation equipment to the cold winter temperatures can reduce longevity and cause unwanted damage.

    With these easy-to-complete winterization tips in mind, you and your farm irrigation system will be well prepared for Old Man Winter. For additional farm irrigation tips, contact one of the irrigation experts at W.P. Law.

    What applications are traveler irrigation systems best for?

    WP Law - Thursday, October 08, 2015
    WP Law

    Traveler irrigation systems use a large sprinkler, also known as a "big gun," that is mounted to a wheeled cart. The sprinkler is then moved across the field, so that it can spray water in a radius of 80 - 250 feet. There are two types of traveler irrigation systems, cable-tow travelers and hose-pull travelers, which can be used for a multitude of agricultural purposes.

    Cable-Tow Traveler Irrigation System

    A cable-tow traveler uses a large sprinkler that is securely mounted on wheeled car. A large, flexible hose is connected to the cart, while the other end of the pipe is connected to the water source. The machine is propelled through the field via the use of a steel cable that is wound around a drum or pulley system that is mounted to the cart. A water motor, turbine, or piston can be used to propel the cable winch. The cable used to propel the machine must be attached to an immovable object located at the edge of the field.

    Using this type of irrigation system will require farmers to make an alleyway through the field. The alley or travel lane will need to be between 6 - 16 feet wide (depending on the size of the machine). Rocks and other abrasive materials should be cleared from the alley. Given the potential difficulties of sloping terrain, the cable-tow traveler irrigation system is best used on flat cropland. It can be used on a variety of agricultural products, such as peanuts, soybeans, corn, sunflowers, and other crops that are grown on flat land.

    Hose-Pull Traveler Irrigation System

    The hose-pull traveler features a large reel that is mounted on a wheeled cart, a large volume gun-type sprinkler that is also mounted on the wheeled cart, and a large semi-rigid polyethylene hose. The trailer mounted hose reel should be parked at the end of a travel lane; water is then fed through the hose to the sprinkler cart. The sprinkler cart is pulled along by the hose, and the hose is then wound onto the trailer-mounted hose reel. Water billows, a turbine, water piston, or auxiliary engine can be used to drive the hose.

    The hose-pull traveler irrigation system can be used on a wide-array of terrain types. A travel lane doesn't need to be used, except for low-growing crops, which makes the hose-pull traveler irrigation system more versatile than its cable-tow counterpart. It can be used for a number of plants, including: soybeans, peanuts, corn, turf, and other crops that can withstand the higher water pressures.

    To learn more about the differences between cable-tow and hose-pull irrigation systems, contact the experts at W. P. Law, Inc. Since 1970, W. P. Law has been providing professional advice and helping members of the agricultural industry choose the best irrigation systems for their crops.

    What should I consider before choosing an irrigation system for my farm?

    WP Law - Thursday, September 10, 2015
    An agricultural field with sprinklers watering the crops

    Choosing an irrigation system is important for the growing success of your farm's produce. However, not all irrigation systems are created equally. From sprinkler irrigation to micro-irrigation, there are a number of factors that you should consider before you can successfully choose an irrigation system.

    Choosing a Farm Irrigation System

    The first tip for choosing your farm's irrigation system is to remember that no one system will be best for every application. With this in mind, keep the following factors in mind:

  • Crops -- What type of crops will you be planting?
  • Size and shape of field -- How will the size and shape of your field affect drainage and water flow?
  • Water source -- Do you have the appropriate water source for your intended irrigation system?
  • Elevation changes -- What are the elevation changes within the field an from the water source to the field?
  • Labor requirements -- Is your chosen irrigation system labor intensive, and do you have the manpower needed to properly operate the system?

  • With these factors in mind, you are ready to explore a variety of irrigation systems. Many farmers and gardeners use drip irrigation. It helps you water the plants that you actually want to have watered, rather than spreading the water far and wide. Through the drip irrigation system, you are less likely to accidentally feed your weed population. Drip irrigation systems are energy and water efficient, since drip irrigation operates at lower pressures pump and pipe sizes can be kept smaller. 

    A center pivot irrigation system is a self-propelled watering system that rotates around a central pivot point. Generally speaking, there are three types of center pivot irrigation systems: Low Energy Precision Application (LEPA), medium pressure sprinklers, and high pressure sprinklers. LEPA discharges water directly to the furrow, which is great when you are trying to grow taller plants, such as corn. A medium pressure sprinkler can be used when water needs to cover a wider area, while a high-pressure sprinkler is the ideal choice for fields with fine textured soils or sharp slopes.

    To learn more about which irrigation system is best for your farm, contact the experts at W.P. Law. W.P. Law offers quality advice on irrigation systems and products. With their guidance you can choose the irrigation system that best meets your specific requirements, including budget, size of field, and type of crop being grown.

    Why won’t the sprinklers on my irrigation system rotate?

    WP Law - Thursday, August 13, 2015

    How to Solve Common Irrigation Issues

    Agricultural Irrigation Systems

    If the sprinklers on your irrigation system fail to properly rotate, then you might find yourself with dead patches of grass, shrubs, crops, or plants. To help you resolve your agricultural irrigation system woes, the experts at W.P. Law Inc. have gathered together a few helpful tips.

    Tips to Resolving Sprinkler Rotation Issues

    If your sprinkler heads aren't rotating, then you might need to look at more than one component of your agricultural irrigation system. The following tips will help you resolve the issues, so that you can go back to growing a healthy crop of plants, shrubs, or crops.

    • Find any and all broken sprinkler heads. -- A broken sprinkler head is often the top culprit for causing rotation issues. A broken sprinkler head can easily be identified by looking for cracked casings, heads that remain buried in the ground, or broken plastic pieces near the sprinkler head. Once you have found a broken sprinkler head, you will need to either repair it or replace it with a new model.
    • Check the water pressure. -- Low water pressure will not only keep parts of your lawn from being properly watered, but it can also contribute to an array of sprinkler head rotation issues. In fact, low water pressure can keep your sprinkler heads from rotating all together. To resolve this irrigation issue, make sure that your valves are fully open. A fully open valve will create the highest water pressure, which will provide sensitive sprinkler heads with the proper amount of pressure.
    • Check for water line leaks and crushed pipes. -- A crushed pipe won't deliver water to the sprinkler heads. When water isn't delivered to the sprinkler head it can't properly rise out of the ground, which can cause it to remain stuck in one position. Alternatively, a leak in the water line can cause low water pressure. As discussed in the previous tip, if the water pressure is too low, then the sprinkler head won't properly rotate. In fact, low water pressure from a leaking pipe might cause the sprinkler head to remain buried in the ground.

    If you have tried all of the above tips and you're still having trouble making your sprinklers rotate, then we invite you to contact our team of experts at W. P. Law, Inc. We would be happy to help you further troubleshoot the sprinkler rotation issue or revitalize your irrigation system to more easily meet your watering needs.

    How do I keep my crops healthy in summer without running a huge water bill?

    WP Law - Thursday, July 09, 2015

    Top Tips to Healthy Summer Crops and Low Water Bills

    Agricultural Irrigation

    During the summer, it can take a lot of water to keep your crops healthy. To avoid excessive water use and to reduce your crop-watering bill, we have gathered together a few helpful tips. From using the correct type of soil to installing an automated irrigation system, we will help you keep your crops healthy and your water bills low.

    Growing healthy crops without breaking the bank on your water bill starts with a few smart gardening tips.

    Add organic matter to your soil.

    The type of soil that you need to grow healthy crops will depend on your local growing conditions, as well as the type of plant that you are trying to grow. If the soil is too sandy, then water will pass through too quickly. If the soil has a large component of clay, then the water will penetrate the soil more slowly. However, if your soil has a healthy amount of compost added to it each growing season, then it will become rich with nutrients, which will promote the health of your crops.

    Use the right watering tools.

    Implementing a cost and water effective solution will depend on your type of crop. For example, many garden crops such as tomatoes, squash, and peppers grow well when water is provided via a drip irrigation system. Grape vines and shrubs also do well with drip irrigation. No matter the type of crop, make sure that you are delivering the water to the root zone. You can save money and water by gently soaking the roots, instead of spraying water over the leafy portions of the crops.

    Whenever possible use "free" water.

    While this tip can't be applied to large growing areas, it is possible to use "free" water on household gardens and homegrown crops. But, what exactly is "free" water? We're talking about rainwater of course! Using a rain barrel or cistern to collect rainwater from your downspouts can be a huge cost saver. Did you know that on average, a 1,000 square foot roof will yield approximately 625 gallons of water from one inch of rain? That's a lot of "free" water that can be put to good use keeping your crops healthy and happy.

    Next time you head out to your garden or check on your crops, keep these tips in mind so that you can reduce your water usage. To learn more about which water efficient watering system will work best for your summer crops, we invite you to contact a member of the W.P. Law team today!

    How do I know what pressure to set the irrigation system in my vineyard?

    WP Law - Thursday, June 11, 2015

    Create and maintain the correct pressure on your vineyard irrigation system to ensure that water distributes evenly.

    Vineyard Irrigation

    Setting the pressure for your vineyard's irrigation system will depend on several factors including the type of irrigation system used, topography, and water requirements. One of the best watering and irrigation tactics for vineyards has been to use drip irrigation. It is important to note that drip irrigation methods should be installed so that they can uniformly apply water. Drip irrigation will use a wire for support and either in-line or punch-in emitters to distribute the water. Whether you choose to install a drip irrigation system, or prefer to use another watering method, it is important that you maintain the correct pressure.

    Pressure Control Considerations

    The proper pressure setting for the irrigation equipment that you choose will vary somewhat by the manufacturer. Always consult the manufacturer’s design information when making this decision.

    • Pressure compensating vs. non-pressure compensating emitters—Since most vineyards are grown in mountainous regions or on other undulating terrain, pressure compensating emitters are a must. Most pressure compensating emitters will compensate between 25 to 50 psi. Pressure compensating emitters allow for the change in pressure caused by change in elevation and friction loss along the lateral drip tubing.
    • Pressure control valves vs. pre-set pressure regulators – Pressure control valves allow for the adjustment of the outgoing pressure and they can also serve as an on-off valve as well. Pre-set pressure regulators usually do not allow for any pressure adjustment and usually have a limited flow range. Pre-set regulators can also be inaccurate at the low or high end of their flow range.
    • Set pressure for system uniformity – The primary goal for proper pressure regulation is system uniformity. The objective is for a plant at the end of a row to receive the same amount of water as the plant at the beginning of the row. Uniformities of 90 to 95% are not uncommon when the system is designed and installed properly.

    Trouble Shooting Pressure Issues

    If maintaining the proper pressure continues to be a problem, here are some things to consider.

    • Check the manufacturer’s design guide to determine the optimum pressure setting.
    • Check for clogged emitters. Clogged emitters lower the system flow rate which will cause the system pressure to increase.
    • Check for clogged filter system. A filter that is not cleaned or backwashing properly can cause low system pressure.
    • Check for leaks. Large leaks or a lot of small leaks can cause low system pressure.

    How can I be cost-efficient in irrigating my crops?

    WP Law - Thursday, May 14, 2015

    Find out how to save money and water irrigating your crops.

    Crop Irrigation

    Irrigation water is an essential tool for the successful growth of vegetables, fruits, and grains throughout the world's various regions. In fact, almost 60 percent of the world's entire freshwater withdrawals are used in irrigation practices. Knowing a few smart irrigation water tips can greatly improve your irrigation efficiencies, while also enhancing your crop yield.

    The Top Five Efficient Irrigation Tips for Crops

    1. Before the start of each new growing season, check your irrigation system. A professional irrigation expert can help you to determine if there are any problem areas within your system or if any of the sprinklers are clogged or otherwise damaged.
    2. An irrigation system is only as good as the points of contact, i.e. the places where the sprinkler heads connect with hoses or pipes. Did you know that a leak the size of a ballpoint pen can waste up to 6,300 gallons of water per month? To be more cost-efficient, while irrigating crops, make sure that your water lines don't have any leaks.
    3. To be the most cost-efficient in your crop irrigation needs, the water needs to be directed only at the areas where the crops are planted. Every drop of water wasted on an area that doesn't need it, is like throwing money down the drain.
    4. Improperly scheduling your irrigation controller can waste both water and money. At the start of each new growing and planting season, be sure to update your system's watering schedule so that it can properly align with the needs of your latest crops, as well as the seasonal output of natural rain water.
    5. Consider using VFD controls on pump stations. If your irrigation system requires a wide range of flow rates, a VFD can lower your pumping costs.

    How Much Area Can I Irrigate with an Impact Sprinkler System?

    WP Law - Thursday, April 09, 2015

    Here’s how to determine the area you can irrigate with your sprinkler system.

    Impact Sprinkler System

    With the droughts we've had in the US the past few years, farmers in areas of the country that haven't needed irrigation in the past now find themselves having to evaluate and install irrigation in their pastures and fields. But working out how much area can be covered by an impact sprinkler system can be confusing at times.

    Proper Irrigation System Design

    At its most basic, an irrigation system needs to be designed to apply enough water to your grow your crop without causing runoff and erosion. You want your system to provide uniform water delivery to the entire area and to do so in an efficient manner to help prevent water loss. You need to decide whether the system should be permanent, movable, or self-moving, depending on your needs.

    When you're designing a new irrigation system, there are a few things to consider. One thing you must consider is topography. Land that is flat usually has more options for overhead irrigation than just impact sprinklers. Sloped land usually is confined to solid set or hand move systems. Crop type and row spacing are other considerations. Will your impact sprinkler system be used only for irrigation or will it also be used for frost protection? These are just a few things that need to be considered when designing an irrigation system using impact sprinklers

    Irrigation scheduling

    The simple definition of an irrigation schedule is answering the questions "How much water does my crop require?" and "How much time do I have to apply this amount of water?" Of course there are several factors that need to be considered when determining an irrigation schedule. Factors such as soil type, topography, prevailing weather conditions, and system efficiency are considerations when determining an irrigation schedule. Many parts of the country require that growers have a Water Management Plan for all of their crop irrigation systems.

    Now that you've had a chance to think about some of the consideration for an impact sprinkler irrigation system, you can contact the professionals at W. P. Law, Inc. for design assistance an as a source for all of your irrigation needs. Contact us today for details.

    How can I conserve water when irrigating my fields?

    WP Law - Thursday, March 12, 2015

    Water conservation when irrigating the fields doesn’t have to be difficult.

    Agricultural Irrigation

    Working in the agriculture industry, you know that conservation is important--not only from a monetary perspective, but also because you want to take care of the world around you. In some cases, you may need to completely change up your irrigation system, if that is the case, call W.P. Law for some suggestions on how to proceed. However, it may be possible to make improvements on your own—here are a few tips to get started.

    • Run your system during the morning hours – Less water is lost due to evaporation if the temperature is cooler like it is in the morning.
    • Fix leaks – Check your sprinklers and other aspects of the irrigation system for small leaks. These may be small but they can add up and cost you water over time.
    • Consider drip irrigation – Many studies show that drip irrigation is more effective and less costly than sprinkler irrigation.
    • Winterize your system – Winterizing your system before the frost hits can save you money and prevent your system from freezing and becoming damaged due to cold weather.
    • Replace sprinkler heads – Even if you aren’t experiencing leaks or other issues, newer sprinkler heads are more efficient today than they were even a few years ago. Investing in new heads (which are often very affordable), can save a lot of water over time.

    Do not feel like you have to work through your irrigation issues alone--W.P. Law is here for you. We carry many top brands of irrigation products and offer irrigation design services that can help you save water, and in turn money, as you water your fields. Give us a call to set up a consultation, so we can show you what a big difference we can make with your irrigation system.

    Why Is Drip Irrigation Recommended for Growing Fruits?

    WP Law - Thursday, February 12, 2015

    Installing a drip irrigation system for your fruit operation is a great way to produce healthier fruit with less maintenance overhead.

    Fruit Drip Irrigation

    Keeping fruit plants adequately watered is an important part of agriculture. Why is drip irrigation so highly recommended for irrigation within this industry? Here are some great details to consider when you're thinking about adding an irrigation system to your agricultural production system.

    Drip irrigation basically provides a small amount of water on a continuous basis to a very small, concentrated area of soil. It often uses very small tubes, micro misting heads, micro sprinkling heads, or soaker hoses. Drip irrigation using small tubes is the most popular option for fruit growing for the following reasons:

    Controlling Where the Water Goes

    In most irrigation systems, the water you're irrigating with sprays across a wider area instead of only where you want it. By using drip irrigation, the water is focused where it's needed - on the plant that's producing the fruit. This helps prevent erosion and allows you to use less water.

    Because drip irrigation allows you to only water the plant you intend, you use much less water in drip irrigation than you do in other irrigation forms. You don't end up watering the ground, grass, pathways, or unwanted plants. The water trickles down to the roots of the plants you want it to and does not gather or provide nutrients to additional areas that might harbor weeds or pests.

    Lower Weed Competition

    Weeds grow well because they can compete with your plants for the same resources - sunlight, soil nutrients, and water. Drip irrigation takes out one part of that equation by minimizing water available to weed plants. In turn, this means that fewer weeds are grown and even fewer become problematic. They can't establish a good foothold in your production areas.

    Fewer Mold and Mildew Issues

    Mold and mildew issues are the bane of any fruit grower's operation. When you use drip irrigation, you're able to keep the water in the soil instead of on the fruit. Water is not spraying or running anywhere other than directly into the soil and the roots. By not providing extra moisture for mold and mildew to grow, you're helping break the life cycle of many common mold and mildew organisms. This turns into lower overhead, as you don't need additional manpower to spray the plants as often with expensive chemicals. Furthermore, you will likely experience higher profits as you're producing more sellable fruit per plant.

    Drip irrigation makes great sense for the average fruit grower, but it can be difficult to determine exactly what your farm's needs are just by looking at the land. Contact us today for a comprehensive consultation on getting your farm set up with efficient, environmentally-friendly drip irrigation.

    Why Am I Losing Pressure in my Riser Pipe?

    WP Law - Thursday, February 05, 2015

    Loss of pressure in your riser pipes can be frustrating and perplexing because pressure loss could be due to a number of factors.

    Loss of Pressure in Riser Pipe

    To find the right solution to your pressure loss, you need to figure out the cause of your sudden or chronic loss of pressure. A few possible causes:

    Problems in the Local Area

    The issue may not be in your facility, but in the water supply that leads to it. There may be planned work that could interrupt pressure at your facility. You should also look for emergency updates in your area that could explain the pressure loss.

    Clogs or Deposits in Pipes

    A clog can keep water from flowing freely, resulting in a loss in pressure. Check the main water supply and water taps throughout your facility. If you have good pressure in one area but not another, this can help you identify where the problem is occurring.

    Rust, algae, and mineral deposits can build up in pipes. This is particularly common in older iron piping systems. These can be physically or chemically removed to expand the volume of the pipe and improve water flow and pressure.

    Broken Valves

    Often, it is not the riser pipe itself that is the issue. The problem can lie with valves that connect pipes to one another. Check all valves to ensure that they are working properly. One that is frozen or not moving correctly can keep water from flowing freely.

    Frozen Pipes

    During cold weather, water can freeze in pipes, causing them to expand and crack. The resulting leaks can cause the water pressure inside your building to fall. To prevent frozen pipes, make sure that they are always well insulated. Keep bay doors closed to keep warmth inside your buildings. If your pipes are exposed to the elements, allowing cold water to drip from faucets can keep it moving and prevent freezing.

    Improperly Installed Pipe Risers

    If you have just installed your system and are not getting the water pressure you need, installation errors could be to blame. When pipe risers are being fabricated and installed, you need to account for the friction and elevation. A qualified installer can help make sure that your system is adequate for your environment and needs.

    WP Law has been assisting businesses with their pipe repair and fabrication needs since 1970. Contact us today to help with your pipe repair project.

    What are some tips for winterizing my pumps?

    WP Law - Wednesday, January 14, 2015

    Avoid the headache of frozen pipes and pumps this winter.

    Frozen Residential Pipes

    Freezing pipes and pumps is a concern of every home and building owner as temperatures fall. Sub-freezing winter temperatures can mean damage to pumps that are not properly winterized. To make sure your water and sump pumps come through winter freezes intact and doing their jobs, do this seasonal maintenance:

    Safety First

    Before doing any winterizing on your pumps, disconnect the power to the unit. This ensures that the pumps are not accidentally turned on while they are being worked on.

    Protect Against Rust

    Clean off any dirt or grime that could accumulate moisture. If there is any raw metal, paint it as it could otherwise rust. Use paint that is lead and chromate-free. Make sure that any pump numbers and motor identification tags are left unpainted and legible.

    Prevent Blockages

    When picking discharge hoses for your sump pump, remember that bigger is better. When water has a wider avenue to escape, there is a lower chance of freezes blocking the pipes. A longer hose can also lead water farther from the building.

    Make Gravity Work for You

    If you have the option, have pipes run downhill from the pump. When the water is flowing away easily, it can prevent back-ups and freezes. Gravity can also keep water pumped from sump pumps from pooling near buildings.

    Keeping Pipes Warm

    Maintaining heat is another way to ensure that the pump's pipes do not freeze and break. Make sure that the end of the discharge pipe is buried in the ground before you insulate; the end will need to go beneath any surface ground that is frozen. Then cover exposed sections of piping in heavy duty tape or lagging straw. If insulation does not seem to provide enough warmth to protect against freezes, additional heat may be needed. Keep basement rooms with sump and water pumps warm enough to keep water from freezing.

    Seasonal Storage

    If you have water pumps that are only used seasonally, they will need to be prepared for storage during the winter months. Make sure that they are thoroughly drained and flushed before storage. If you are storing a pump dry, check that all ducts and pipes are sealed to prevent rodents from getting inside. If wrapping in plastic, ensure that air can get in and out. Otherwise, accumulated condensation can cause rust.

    By inspecting and maintaining pipes and pumps, you can keep your system in working order and prevent costly repairs. Are your pumps due for repair or annual maintenance? Contact WP Law for a consultation.

    DIY: Installing Drip Irrigation From a Water Faucet

    WP Law - Thursday, June 19, 2014

    How to Install Drip Irrigation From a Water Faucet.

    DIY: Installing Drip Irrigation From a Water Faucet
    Homeowners are turning to drip irrigation systems to help them manage their water usage, as well as to save money. By taking a do-it-yourself approach, you can reduce your water use and your drip irrigation system installation costs by over 50 percent! Drip irrigation can be very simple to install when just dealing with a central located water faucet outside your home. You will first want to make a simple plan or design and then make a list of materials you will need to buy.

    Here at W.P. Law, we provide drip irrigation products including drip tubing and drip fittings, drip emitters, irrigation controllers, drip filters, timers, valves and drip irrigation accessories. Also with our great customer service, we can tell you how to install drip irrigation at your house or job, with suggested layouts and design, tips on selecting the right emitters and other useful information. We offer customized drip kits ranging from greenhouse to vegetable gardens.

    When installing a simple drip irrigation system outside your home, off of a water faucet, here are the supplies you will need. You will first start need a hose end timer, this is what you will hook up to your faucet. We provide a dual port timer so it won’t tie up your faucet. If you don’t buy a dual port, you will need to buy a “Y” faucet adapter and install it before the timer. Next thing you will need is a Y filter and pressure regulator. These are the items you will install right after your timer. Next you will need to buy a roll of solid drip tubing; the length of tubing will be determined by an estimated measurement throughout the bed or beds you are irrigating. Once you hook up the drip tubing, with an adaptor to the pressure regulator, you will need to curve the drip tubing in and out of your plants getting the tubing close to the stem and under the drip line of the plants by using landscape staples. By using drip T’s and 90’s you can branch off into different directions to get good coverage in your plant beds. After the tubing is installed and the line ends are pinched off with end clamps, you will need to install emitters into the tubing at every plant. Best way is to put ½ gal or 1 gal emitters on either side of the stems of the plants, 2 gal emitters on either side of trees. Once you have all the tubing and emitters down, it’s good to place mulching material down onto the tubing to cover it up. This allows protection for the tubing and is aesthetically pleasing. Program your timer considering the plant materials, time of year, and location.

    The 3 Most Surprising Benefits of Irrigation Valve Boxes

    WP Law - Monday, June 09, 2014

    How can irrigation valve boxes help you?

    The 3 Most Surprising Benefits of Irrigation Valve Boxes
    Irrigation valve boxes are an important part of irrigation systems, and they are also one of the most overlooked aspects of system design. Valve boxes provide easy access to buried irrigation control valves. Irrigation control valves and backflow preventers require access from time-to-time to perform maintenance and testing. Valve boxes also provide protection for these essential components of your irrigation system. Here are three things to consider when selecting and installing a valve box:

    1. Size Matters – Using a valve box that is too small can be a common mistake. Many installers try to put too many valves in one valve box or use a smaller size valve box than is necessary. Smaller valve boxes are less expensive, but keep in mind you will want plenty of room to access the control valve if you ever have to come back and perform any maintenance or repairs. Make sure the valve box you select allows for plenty of room to work.

    2. Allow For Drainage – No one like to put their hands in a standing pool of muddy water in a valve box. By installing 3 to 4 inches of pea gravel in the bottom of the valve box will allow water to drain away from the valve box more easily.

    3. Keep The Box Off Of The Pipe – When installing a valve box, make sure that the base of the valve box is not resting directly on top of the pipe. The base of the box should ideally rest on undisturbed or compacted soil. If the valve box is resting directly on the pipeline it could cause a pipe to break if someone were to drive a heavy vehicle across the top of the valve box.

    Piping Systems Key in Irrigation Design

    The Best Ways to Utilize Piping Systems

    Piping systems can be a pivotal part of your irrigation system. Design should always be a key focus. In order to get the most out of your system, you must build one designed to offer peak efficiency through all four seasons.

    Key Design Components

    Systems should be designed to work independently of each other. This means installing shut off or control valves so fluid can be directed to designated zones. The zone system allows your system to address problems, such as pests or dry soil, right where the problem exists, saving you money in the long run.

    Control systems should also be designed to work efficiently by decreasing the amount of labor involved in your project. A good example of this is remote access, which allows faster and easier adjustment of your watering system. As you inspect your crops or drainage system, you can access the controller via a smart device and make changes to correct issues you find while you are in the field.

    Integrated pest management is also important. Being able to apply liquid pest control measures by zone allows you to target pest problems where they occur. This cuts back on the amount of chemicals used and adds major savings to your wallet. For agriculture applications this can be a critical design element.

    Water conservation is another integral design element. The cost of water will increase as areas are affected by drought. Monitors, such as soil moisture probes, can work with your system to deliver water when soil humidity drops to a specified range.

    Figure out the best design for your irrigation today. Consult us at WP Law, Inc. for a system that meets all of your needs.

    2 Facts About Agriculture Irrigation Systems That Will Change the Way You Irrigate

    WP Law - Thursday, April 03, 2014

    Irrigation systems help farmers feed America.

    2 Facts About Agriculture Irrigation Systems That Will Change the Way You Irrigate

    As the cost of water goes up, the design of irrigation systems is changing to help reduce overhead. Right now is the time for home agriculture and commercial agriculture operations to invest in water-saving agriculture irrigation systems. In 2013, 18 states were listed as abnormally dry, 10 were listed as having extreme droughts, and 4 were listed as being in a state of exceptionally severe drought. (Check out the Drought Map for detailed information.)

    The cost of water is going to continue to rise. In areas like California there is already extreme pressure between agriculture and cities. It’s only going to increase as drought conditions continue to worsen. Investing in water-saving agriculture irrigation systems will help your operation meet its production goals without adding to the burden of water costs.

    Water Saving Features are Becoming Crucial

    Using California as an example again, a small area of farmers invested in special design features for saving water over 20 years ago. Those farmers are able to buy water for $8 an acre where others are paying over $1300 for an acre of water. This dramatic increase in the price of doing business is also reflected at the market level. How farmers utilize irrigation is a crucial step in farming and in the cost of many different goods. The cost of water is going to continue to rise. How farmers invest in that process now can make or break their business.

    The Most Common Problems with Farm Irrigation Systems

    WP Law - Thursday, November 07, 2013

    Farm Irrigation Systems Need Dedicated Care

    The Most Common Problems with Farm Irrigation Systems

    Two of the most common problems with farm irrigation systems have to do with irrigation scheduling. Irrigation scheduling is simply answering the questions of “When do I water?” and “How long do I water?”. Starting an irrigation cycle too early and/or running an irrigation cycle too long is considered over watering. At the very least this practice wastes water and money. However, overwatering can cause crop damage if done on a prolonged basis. Likewise, starting an irrigation cycle too late or not running the system for a long enough period of time is considered under watering and can cause reduced yields and poor crop quality which can affect price. Looking at these problems in depth is the key to minimizing their financial and practical impact on crops.

    The two most common methods for dealing with these problems are ET based control systems and soil moisture based control systems. Evapotranspiration (ET) is the combined process through which soil moisture is lost directly to the atmosphere through evaporation and plants taking water out of the soil and transpiring it to the atmosphere. ET is typically a calculated value that takes into account factors such as recent rainfall, relative humidity, solar radiation, and a crop coefficient that accounts for the plant size and stage of growth. The calculated ET will give the grower an estimate as to how much water the soil is losing due to ET. Once he knows how much soil moisture he is losing he can determine how long he needs to irrigation to replace the lost soil moisture.

    Soil moisture based control systems use soil moisture sensors to measure the actual soil moisture. This method is typically more accurate the ET calculations because it is actually measuring the moisture level in the soil instead of calculating what should be there. Soil moisture control systems tell the grower when to begin an irrigation cycle and also tell him when the soil moisture level reaches field capacity.

    Occasionally ET based control systems are used with some type of soil moisture sensor such as a tensiometer to provide some feedback as to the accuracy of the ET calculations. Whichever method you use, ET or soil moisture based controls provide a much more consistent and reliable method of controlling your irrigation system than the “It looks kind of dry, so I guess I’ll water” method.

    2 Ideas You Can Steal From Pump Stations

    WP Law - Monday, August 19, 2013

    You might not ever have thought about drawing inspiration from pump stations.

    Ideas You Can Steal From Pump Stations

    You can look to pump stations for some excellent water conservation and sump fertilization techniques.

    1: Water Conservation:
    All that rain water that falls in the winter and spring can be collected using creative drainage and collection ponds. We see the use of rain barrels, which attach to a gutter to collect rain water off of roofs. The same principle applies to collecting rainwater from surrounding land. With a large enough storage facility, farmers in arid communities would increase their available water supply without having the legal hassle of fighting for more water rights.

    2: Sump fertilization system:
    In areas where there are dairies and a sump situation where manure can be stored in an open pit, or lagoon, water can be added when needed and that excess water pumped into the irrigation system of supporting the growth of fields for hay, alfalfa, and even corn.

    It would be the ultimate form of recycling and likely save the farmer a bundle in the cost of fertilizer. They way this could work would be to set up a pit with a steel grate over the top. Manure is placed on top of the grate and allowed to decompose like compost.

    When it is time to fertilize crops, water can be sprayed over the manure and would collect into the pit beneath the steel grate. When the water reached a certain level, it could be pumped out either into a truck, or directly into the irrigation system. It can also be pumped to empty fields prior to planting or to fallow fields as a means of kick starting soil building during the winter.

    Just some thoughts to ponder...

    3 Best-Kept Secrets about Farm Irrigation Systems

    WP Law - Thursday, August 01, 2013

    Learn how farm irrigation systems save precious resources.

    Farm Irrigation Systems

    Farm irrigation systems are vitally important to managing crop yield and control the cost of water. The scientific community, the business community, and the farming community have been discussing water shortage on a global basis with government agencies.

    The general public may not understand the importance of freshwater and how the availability and control of water is changing. For instance, some corporations want to control water, and you can research that searching for peak freshwater. This fact makes farm irrigation extremely important to American farmers.

    As water conservation efforts continue to advance, farmers can do a few things to help themselves out. Here are three well-kept secrets that can help any farmer when it comes to their irrigation system:

    1. One of the best-kept secrets about farm irrigation is the fact that these systems come in various styles and levels of efficiency. When you have the option, upgrade to more efficient systems or emitters.

    2. The second best kept secret is the use of soil moisture monitoring devices. These devices help to alert the farmer to the best time to irrigate. These sorts of devices are going to become more critical as water becomes more in-demand.

    3. The third best kept secret is found in systems that allow you to adjust for wind. Windy conditions blow water all over the place, and outside of the optimum root zones. Being able to adjust an irrigation system to accommodate windy conditions saves water, reduces weeds, and allows your plants to receive better watering.

    The Happy Farmer's Guide to Drip Irrigation Products

    WP Law - Monday, May 20, 2013

    Happy farmers know drip irrigation products provide an efficient way to keep crops watered.

    The Happy Farmer's Guide to Drip Irrigation Products

    Drip irrigation products are a water saving addition to any irrigation system, taking care of plants while showing kindness to the overall environment. This method of watering works with water moving at low pressure through plastic pipes. Small emission devices in these pipes distribute the water in a slow even drip giving the perfect measure of water to plants when placed at a proper distance.

    Drip irrigation works well in a wide variety of soil types. Because water is applied at a slow rate it has time to soak into the soil before running off. Since water runoff is almost completely eliminated, drip irrigation is ideal for irrigating crops grown on hillsides.

    Since drip irrigation uses small orifices to control the flow of water, clogging can be a problem. But with the proper selection and use of a quality filtration system, clogging is rarely a problem.

    Water quality can also be an issue with drip irrigation products, but economical water treatment solutions can solve most water quality issues.

    The Victory Garden School of Automated Plant Watering Systems

    WP Law - Monday, May 13, 2013

    What type of automatic plant watering system is right for your garden, business, or lawn?

    The Victory Garden School of Automated Plant Watering Systems

    Victory gardens are making a comeback. No wonder they’re popular; they yield whole, fresh, and local produce, they’re a morale boost to those who tend them, and they provide built-in exercise from planting to weeding.

    Not only do gardens require the sweat of your brow, they also need regular watering, no matter what Mother Nature provides. That’s where automated plant watering systems come in handy. A system that is installed properly helps owners water the garden on a set schedule. Most systems are metered and help save on your water bills too.

    Determining the water pressure and the amount of water (flow rate) that you have available in your location will be an important step. Each system has different requirements so it’s important to know this information before installing.

    • Micro-spray systems work well with orchard crops such as apple and peaches where the root zones are spread over a large area. Micro-spray systems also work well in loose porous soils such as those found in planting containers and annual beds. Micro-spray systems operate at low pressure (typically 30 psi) and a typical micro sprinkler will have a flow rate of between 10-30 gallons per hour.

    • Drip systems use emitters to apply water in drops to the plant’s root zone. Drip systems also operate at low pressure (typically 30 psi) and a drip typical drip emitter will have a flow rate of 0.5, 1, or 2 gallons per hour. Drip emitters can either be externally installed by punching them into the drip tubing, or they can come pre-installed in the tubing at a regular spaced interval (typically 12”, 18”, 24”, and 36”).

    • In ground pop-up sprinkler systems are the best automatic plant watering system for the lawn. The sprinkler heads pop up when water is turned on and retract back when water is turned off. This allows you to mow without hitting the sprinklers. Pop-up sprinklers consist of two types, rotary sprinklers and fixed patter spray heads. Rotary lawn sprinklers typically have a radius of 15 to 40 feet. Spray heads usually have a radius of 8 to 18 feet.

    Two Water Pump Purchasing Tips for the Home Gardener

    WP Law - Thursday, May 02, 2013

    Every gardener wants to be able to water easily. Read on for two water pump features you’ll love.

    Two Water Pump Purchasing Tips for the Home Gardener

    Having your own garden is a great way to produce your own food. However, if you live in a drought-prone area, you know water is at a premium and you may have to get creative to keep your garden green and growing.

    Part of getting creative means understanding which features to look for as you invest in a water pump station. Make sure you check out these two tips before purchasing a water pump for your irrigation system.

    • Look at the pump’s performance curve and compare it to your system requirements. A pump’s performance curve will show you the relationship between flow-rate (GPM) and pressure (PSI). For most centrifugal pumps, the higher the pressure the lower the flow-rate, and the lower the pressure the higher the flow-rate. Many homeowners purchase pumps at the big box stores based on horsepower alone and do not consider the pumps performance. For example, stores will advertise a pump “delivers up to 75 GPM” or “delivers 60 PSI”. This can be somewhat misleading. While the pump in question will indeed deliver 75 GPM, it does so at a very low pressure (not 60 PSI), and yes this pump will deliver 60 PSI, but it will do so at a very low flow-rate (not at 75 GPM). The lesson to learn here is, look at the pump’s entire performance curve (or chart) to determine if it meets your system’s requirements.

    • Consider using a self-priming centrifugal pump if you are pumping out of any body of surface water (pond, lake, or stream). Self-priming centrifugal pumps are commonly used for irrigating average-sized lawns and gardens. These ease of operation make them ideal for many DIYers. The pump casing on self-priming centrifugal pumps does need to be primed (the process of filling the pump casing with water before turning the pump on) before system start-up. However, self-primers can usually tolerate small suction leaks that would cause straight centrifugal pumps to lose prime.

    That bumper crop you’re dreaming of is only a few months away. With a water pump system in place, you don’t have to worry about irregular rainfall. Just pump your own, and keep your garden growing!

    How to prevent frost damage using agriculture irrigation systems

    The damage that is done to crops every year during late periods of cold weather is a big concern for growers. Late spring freezes and cold temperatures can severely damage crops. As a result, growers suffer the loss of crops and consumers suffer at the checkout by having to pay higher prices.

    In many cases, damage from frost can be prevented by using overhead agriculture irrigation systems during the frost period.

    As the water freezes on the crops, latent heat gets released and keeps the plant’s temperature from dropping below freezing, and protects it from damage. You should continue to irrigate the crops until the sun rises and warms the ground. When the temperatures go above freezing, and the ice begins to melt, you can stop irrigation.

    It’s important to note that if the wind is blowing over 15 mph, then irrigation will not fully protect the crops. There are many methods for growers to protect their crops during frost, irrigation is one of the best.

    Three types of greenhouse irrigation systems.

    Greenhouse irrigation is important to produce healthy plants and vegetables. There are several different types of irrigation systems that can easily be installed in greenhouses. Choosing the right system for your greenhouse is vital to the productivity of your crop. Here are three popular types of greenhouse irrigation systems:

    Overhead Irrigation: Overhead irrigation is a popular form of irrigation for greenhouses. It is relatively inexpensive to install and maintain. There are different types of spray heads that include both fixed and rotating heads.

    Drip Irrigation: Drip irrigation is also inexpensive to install and maintain. Drip irrigation works by dripping water directly into each individual pot. There is no worry about overspray, or wasting water. It is one of the most efficient methods for watering plants.

    Misting Watering System: A misting watering system is used for propagating plants from small seeds or cuttings. The ultrafine mist keeps the soil moist but does not dislodge the soil. These micro-sprinklers spray a very fine mist onto the plants.

    With the country experiencing some of the worst drought conditions in history, irrigating your crops is vital to ensuring a healthy and successful crop. Choosing the right irrigation system that fits your needs and budget can seem confusing and frustrating.

    Here are two irrigation systems farmers are finding success with.

    1. Drip Irrigation: Drip irrigation systems are perfect for high value vegetable and orchard crops. They make efficient use of water and can also be used with fertilizer injection systems to apply fertilizer along with water directly to the root zone. Since drip irrigation systems are typically below ground, farmers can still perform other task on the farm such as spraying and cultivating while the irrigation system is running.

    2. Traveling Gun Irrigation: Traveling gun irrigation systems are versatile and can be used on a variety of crops. They are a great alternative for oddly shaped fields and for farmers with multiple fields to irrigate. They easily moved from field to field and there are different sizes available to fit your needs. There are fuel powered and water powered models available.

    Tips on how to choose the right greenhouse irrigation system for your needs.

    Choosing the right greenhouse irrigation is important to ensure the health and growth of your greenhouse plants. Greenhouses come in a variety of sizes and styles and provide an optimal growing environment for your vegetables, plants, and flowers. Irrigating a greenhouse is different from irrigating a backyard garden or landscape.

    Depending on your specific needs, the following two systems are great options for greenhouse irrigation:

    • Drip irrigation system: A drip irrigation system consists of a series of overhead hoses attached to smaller distribution tubes. At the end of each tube is an emission device (emitter or spray stake). Theses emission devices are placed into each pot or container. Water drip or sprays directly into each container. This system works well for larger containers and hanging baskets.

    • Misting watering system: A misting system is an effective watering system for greenhouses especially if you use your greenhouse for plant propagation. This system is similar to a drip system with the exception that small micro-sprinklers are used. These micro-sprinklers deliver a very fine mist. This type of system is ideal for plant propagation and seed germination since the very small droplets do not disturb the soil in containers and flats.

    greenhouse irrigationUsing the proper greenhouse irrigation will greatly improve the growth of your vegetables and flowers and create healthier plants. Here are some options to consider:

    • Automated watering system: An automated watering system can help save you time and money keeping your greenhouse plants watered. With the system set to water automatically for a specified period of time, you no longer need to worry about remembering to water. The system does the watering for you so you can spend your time doing other things.

    • Drip or micro-sprinkler watering system: A drip or micro-sprinkler system is the most eco-friendly watering system for your greenhouse. These low pressure, low volume systems apply water efficiently and effectively thus conserving water and energy.

    • Combination of systems: Depending on the types of plants you are growing and the size of your greenhouse, a combination of systems may be your best option to effectively water your greenhouse.

    Check with an irrigation expert before making your final decision about which irrigation system to use. They can help you create an effective irrigation system to ensure a healthier garden this season.

    Farm Irrigation Systems: Top 3 Questions

    Flip Law - Thursday, March 22, 2012

    Farm irrigation systems play an important role in bringing the farmer’s crops to your table.

    farm irrigation systemFarmers can’t always rely on the rain to bring water to their crops. It is too unpredictable for them to rely on. Therefore they need to install irrigation systems to ensure healthy and plentiful crops. There are many different types of irrigation that farmers use.

    Here are the top three questions people ask about farm irrigation systems.
    1. What is the difference between drip irrigation and micro sprinkler irrigation? Both systems are considered low volume and low pressure systems. Drip irrigation supplies water to the crop at or near the root zone through the use of emitters. Water “drips” from these emitters at a very low rate, typically 1, or 2 gallons per hour. Micro sprinkler irrigation also applies water near the root zone by using small stake mounted sprinklers or jets. These micro-sprinklers apply water with a small spray or fan shaped pattern, usually at a rate of 10-15 gallons per hour. The spray pattern covers a larger area than drip emitters and is usually used to irrigate fruit trees such as peaches and citrus. Because these micro sprinklers are located beneath the tree canopy and are located only a few inches above the ground they offer many of the same benefits as drip irrigation (less evaporation, less runoff, higher efficiency, etc.).
    2. Why do farmers turn sprinklers on during frost warnings? Many early spring fruit crops such as strawberries require some type of frost protection system. Many farmers utilize an overhead sprinkler frost protection system. Sprinkler frost protection systems work because of the thermodynamic properties of water. When water changes from a liquid to a frozen state it loses heat (latent heat of fusion). The heat that the water loses keeps the plant tissue just above freezing. Farmers must continually run the sprinkler system during freezing temperatures because water must be constantly changing from a liquid to a frozen state. For this reason farmers will turn on the frost protection system before the air temperature drops below freezing and will run their system continually until the air temperature is well above freezing.
    3. How do you determine what type of irrigation to use? The type of irrigation system used usually depends on the crops you are growing. Vegetable or other truck crops usually use drip irrigation. Peaches and other tree-fruit crops are also well suited for drip irrigation and/or micro sprinklers but many growers also use overhead sprinklers such as “big guns” and traveling guns. Row crops typically use center pivot systems or traveling guns.

    Agriculture Irrigation Systems - 3 frequently asked questions

    Flip Law - Monday, March 05, 2012

    Agriculture irrigation systems are a necessity to deliver healthy and abundant crops.

    agriculture irrigation systemAgriculture irrigation systems play a major role in farming and in ensuring healthy and bountiful crops. There are many questions about irrigation and why it is important in the farming industry. Here are 3 frequently asked questions.

    • 1) What are the different types of irrigation?
      • Sprinkler Irrigation: Sprinkler irrigation is where the water is delivered through on overhead sprinkler system. There are different types of sprinkler irrigation that the farming industry uses.
      • Drip Irrigation: Drip irrigation is where the water is delivered by low volume, low pressure emitters or micro sprinklers directly to the root zone of the crop. Drip irrigation is primarily used on high-value crops such as fruits and vegetables.
      • Subsurface Drip Irrigation: Subsurface drip irrigation is essentially the same as drip irrigation except the emitter lines are buried underground. Subsurface drip irrigation is primarily used on high-value row crops such as corn and cotton.
    • 2) Where does the water come from? There are many sources for water used in farming irrigation. The most common are ponds, wells, lakes, rivers, collected rainwater and treated wastewater.
    • 3) What are the benefits of an irrigation system? Crops cannot grow without water. Rainfall is too unpredictable and sometimes scarce.

    An irrigation system will ensure that the crops get the required amount of water needed to grow healthy and abundantly. If you’re looking to install new agriculture irrigation systems on your farm, ask WP Law’s irrigation experts for a system that meets your land’s particular needs.

    Garden Drip Irrigation Made Easy

    - Monday, March 21, 2011
    Drip irrigation on home vegetable gardens has gained in popularity over the years because of the many benefits it provides.  By supplying water directly to the root zone of your crop, drip irrigation helps reduce disease pressure often associated with over-head watering by keeping the leaves of the crop dry.  Drip irrigation in vegetable gardens also helps limit the amount of weeds by keeping area between rows dry as well.

    The irrigation professionals at W.P. Law Inc. have developed a garden drip irrigation kit that helps take the guess work out of supplying water to your garden.  Our garden drip irrigation kits can be customized based on the size and number of rows in you garden.   These kits use a 5/8" drip tape with built in drip emitters every 12 inches that drip water slowly to the root zone of your garden.  The drip tape is available in a 1,000 foot roll and requires only a 1/2 gallon of water per minute for every 100 feet of drip tape or row.  Many growers that have a limited amount of water available are able to utilize our garden drip tape kits to irrigate their garden. 

    The drip tape attaches to  5/8" polyethylene solid drip tubing that is connected to a water supply such as a faucet.  At the faucet, simply screw on the drip filter and pressure reducer and connect the solid drip tubing that will supply the drip tape.  Assembly is simple and does not require any advanced plumbing skills to install.

    Many growers prefer to add a hose faucet timer in order to automate their garden drip irrigation system.  These timers can be programmed to turn the drip irrigation on automatically each day with multiple start times.  Another common device used to help take the work out of your home garden is the addition of a fertilizer injector.  These fertilizer injectors can be used to inject soluble fertilizer into the drip tape system.

    Designing Irrigation Systems…Planning Ahead

    Designing Irrigation Systems…Planning Ahead

    When the decision is made to add an irrigation system to your landscape or farm, there is no doubt that it pays to have an irrigation design done.  Having a complete irrigation design will maximize the effectiveness of the irrigation system, providing cost savings over the “buy-it-and-try-it” method, which usually leads to malfunctions and re-workings. While most would-be irrigation system owners would admit the need for an irrigation design, it is surprising how few take the time to plan-ahead.  When the design process is delayed until the last minute, the procrastination could lead to inflated costs when compared to the same irrigation system planned in advance.

    By planning ahead, you are able to take advantage of several money saving opportunities.  We can make sure that all necessary parts for the irrigation system are in stock for the complete job, often eliminating freight charges that show up when trying to obtain parts at the last-minute.  Additionally, we can pair jobs together, allowing us to obtain better pricing for you on the larger quantities.  You can see additional cost-savings if an estimate is obtained ahead of time, as we can avoid some price increases by having a prior quote honored.  

    In addition to the cost-savings, we will all obtain a greater peace of mind by having more time to work out the details of a particular job.  Just like fingerprints, no two systems are identical.  As more information is taken into consideration, we can fine-tune and personalize any given irrigation design to meet your specific needs.
