Connecting Pressure, Flow and Your Overall Efficiency | by Nicole Alvarez

This piece was written for and published by Senninger Irrigation, and reprinted with permission.

Our team has traveled all over the USA and across the globe and noticed two strange things when it comes to pressure regulation: some growers will tell you that pressure regulation is the best way to save water and energy, while others will claim pressure regulation is nothing but a waste of time and money unless you have sloped fields.

We’ve been highlighting the importance of pressure regulation for years but regulation has never been as important as it is now with drought conditions in numerous areas and diminishing aquifer levels. That’s why we’ve created a quick pressure regulation FAQ list to help explain not just how a regulator works, but why they’re needed and how you can tell if yours is working.

How does a pressure regulator work? 

The basic function of a pressure regulator is to limit excessive and varying inlet pressures to a constant outlet pressure. This is done to maintain the desired performance of a sprinkling device.

Pressure regulators accomplish this by automatically modulating their area of opening. By changing the area of opening as upstream pressures fluctuate, pressure loss through the regulator changes proportionally. This allows them to maintain the downstream pressure at a relative constant.

Why do I need pressure regulators?

No matter what type of irrigation machine you have, correct pressure is essential for optimum distribution uniformity and proper flow through emitters. Crops need the right amount of water at the right time and pressure regulators ensure this need is met.

Sprinklers are made to operate within a specific range of flows and pressures. They’ll maintain their application pattern and adequate droplet size as long as they can operate under normal conditions. If these conditions are altered, their application pattern will be affected and you could easily run into uniformity issues, over or under watering, and irregular crop growth.

What causes pressure deviations?

Every irrigation machine will experience some sort of pressure fluctuation. The most common reasons for pressure fluctuations include:

• Elevation changes in a field 
• Pressure loss through pipe fittings 
• End guns cycling on and off 
• Cycling of various irrigation zones and valves 

Do I need a pressure regulator with flat land?

Yes! Your system pressure can change due to the various causes listed above and more. Elevation is just one of the many things that cause pressure fluctuations.

No matter what degree of elevation you have, controlling flow and pressure is essential for machines operating at lower pressures. For example, if a system operating at 30 psi (2.07 bar) experiences a 10 percent flow variation, that will result in a 6 PSI (0.41 bar) pressure variation. That flow variation can adversely impact sprinkler performance and ultimately yields.

How does pressure affect my flow rate?

The operating pressure of an irrigation machine always affects the flow rate. Higher pressures increase flow along any pipe. As that flow increases, water velocity increases as well. This results in pressure decreasing downstream due to friction loss. When water is rushing through a pipe at high velocities, the interior walls of the pipe create friction against it, which causes pressure loss.

How long does a pressure regulator last?

Senninger pressure regulators are built using high-impact engineering grade thermoplastics and are 100 percent water-tested at our facilities. However, like sprinklers, they do not last forever. Irrigators are encouraged to check their pressure regulators at least every three years. Factors that can shorten a pressure regulator’s lifespan include:

• Unflushed chemicals in the pipeline 
• Suspended abrasive materials in the water 
• Long operating hours 

How can I tell if a pressure regulator is bad?

Issues such as dry spots near the head, overwatering in a doughnut shaped pattern, uneven crop growth and streaking in the field and misting are all common signs of pressure regulator malfunctions. Using yield maps and even aerial imaging may prove helpful in identifying issues.

End-of-Season Checklist | by Nicole Alvarez

This piece was written for and published by Senninger Irrigation, and reprinted with permission.

This year’s irrigation season is ending for many farmers across the western hemisphere. Several are already working in their combines and reaping the fruits of their labor.

It’s tempting to forget about pivots and just focus on getting crops out of the field and into a bin during harvest. Yet this is one of the best times to evaluate sprinkler packages to make sure your pivots are in top shape and ready for another growing season. This check helps prevent unwanted surprises and helps ensure crops will be irrigated according to schedule. 

We suggest you take a look at this end-of-season checklist for a quick overview of the things you should take care of:

1. Get Your Sprinkler Package Chart
Find a copy of the sprinkler package chart. This contains the location of all sprinklers and pressure regulators along the center pivot. It will also include detailed information for each sprinkler’s nozzle size or flow rate. You’ll need it a little later when you’re walking along your pivot verifying sprinkler location and noting potential issues.

2. Flush Your System
Check the main pipe running from the well to the pivot itself for any potential leaks. Next, remove the sand trap on your pivot and flush the entire system for several minutes. (Make sure the system is not under pressure when you remove the sand trap!) This will flush out any debris or foreign materials that may plug the sprinkler heads or pressure regulators.

Sprinklers on the first few spans are particularly prone to plugging due to their smaller nozzles size so we recommend a good system flush at least once a year.

3. Check System Pressures
Using a pressure gauge, verify your pressure at the pump, pivot point, and at the end of the pivot. Make sure you operate the center pivot  at the design pressure.

Pressure should be at least 5 PSI above the pressure regulator rating. If you have a 10 PSI pressure regulator, your pressure gauge should read a minimum of 15 PSI. Compare the numbers to the design pressure in your sprinkler package chart to make sure everything matches.

Note: It’s best to check pressure with the pivot parked in the same location!

4. Check System Flows 
Sometimes farmers discover that the nozzles along each span do not correspond with what the printout indicates. This is why it’s important to keep your chart on hand

Check the system flow rates by comparing each sprinkler to the corresponding outlet on the chart. Each sprinkler’s nozzle and flow rate should match the number on the sprinkler package chart. If the nozzles are wrong, you may be over or under watering.

If you have a flow meter, verify that it’s taking the correct measurements. Solving issues like a flow meter not receiving a signal or unstable flow rates might require a little detective work on your part using your flow meter installation and troubleshooting guide.

5. Evaluate Sprinkler’s Wetted Patterns
Visually inspect all sprinklers for potential damage, lost parts, and for consistency and uniformity in their distribution patterns. Assure that sprinkler overlap is sufficient.

Disassemble any sprinklers with poor distribution patterns or overlap and check for plugging or defective parts. Sprinklers can wear out and will stop rotating – or rotate out of control. Check sprinkler deflector pads to ensure they do not have a build-up of materials that could affect the distribution pattern or flow rate. You might also notice kinked or damaged drop hoses that need fixing.

Sprinkler issues can result in extra water being applied is some areas and insufficient water being applied in others. This affects water application uniformity and can reduce yields.

According to the University of Nebraska-Lincoln, depending on the location of the problem along the pivot pipeline, the economic impact of a single sprinkler problem can be significant in the amount of yield reduction it causes. This is especially true for sprinklers on the outer 30 percent of the center pivot.

If You Notice Something’s Off….
Hopefully, you won’t notice any runoff or a lack of uniformity while inspecting your sprinklers, but if you do:

• Go back to your sprinkler package chart and check the nozzle sizes and placement of sprinklers that are showing problems – they may be incorrectly installed.
• Consider evaluating your tillage practices to enhance infiltration and decrease runoff.
• Evaluate your system and consider whether a new sprinkler package would be beneficial. Select a sprinkler device that irrigates with low application intensity over a large diameter, and creates relatively large droplets that can combat wind-drift and evaporation.
• If you want to renozzle your system, check with your local power company for possible incentives when you switch to lower pressure systems.

Crop Insurance Approved for Pivot-Irrigated Rice | by Kelly Downing

It has taken a lot of time and work (mostly by other people), but last week we finally got some good news in the pivot rice world. The USDA’s Risk Management Agency board of directors approved the application to provide crop insurance coverage for producers who want to grow rice with pivots. This means that by as early as next spring producers will be able to insure their pivot-irrigated rice crop. This decision comes at an opportune time, as weakening corn and soybean prices and decent rice price trends are increasing the interest in rice among farmers.

The real winners, in my opinion, are growers who want the flexibility to incorporate rice into their other crop rotations. This will make it more feasible to grow rice in non-traditional locations like upland, sloping, and sandy soils. It is particularly significant now that the new Farm Bill places increased emphasis on crop insurance as the backbone of its programs. More and more lenders are insisting on crop insurance as a prerequisite for funding operating loans, and this helps make that happen.

John Taylor’s rice field in Arkansas.

The best news is that this gives farmers another tool to increase their efficiency, sustainability, and profitability. The reduction in water use, pumping requirements, and greenhouse gas emissions will not only make their operations more profitable, but also more ecologically sound and sustainable — “green,” in today’s parlance.

The initial rollout of this program will be in Missouri, Arkansas, and Texas, places where there has been interest and research, as well as areas where water is, or will become, a limiting factor in production. I am hopeful that, as the program grows and matures, other areas will be added.

Our participation in this effort has been very interesting. It was never about selling pivots; rather, the effort has always been to define and offer to farmers the tools to increase efficiency and profit, while maintaining their ability to keep farming in a sustainable manner. Adding rice to a corn/soybean/cotton rotation (or some variation) can also help manage the problem of herbicide-resistant weeds that is rapidly growing throughout the country.

I just looked at the blog post I wrote back in April. Wow, have things changed since then! At that time, our local soil conditions were exceptionally dry, after a long, cold, dry winter. I was worried that there would be real problems getting a crop out of the ground. Of course now, at the beginning of July, many people are begging for the rain (and associated violent storms) to stop. It has turned into a relatively cool, very wet spring; so much so that some growers in my area have had to replant twice—once due to frost and a second time due to flood.

For those who have escaped the disasters, however, growing conditions have been quite good, and many of the crops I see in my travels around the Midwest and upper Delta look excellent.

Weather is one of the vagaries of farming that we try to manage, but cannot control. I hope that things go well for you this summer, and I look forward to checking in again with further updates.

Be safe, enjoy the summer, and stay in touch. Let us know how things are going where you are.

Striving to Help Africa’s Small Farmers | by Shannon Peterson

It’s hard to deny that the effects of center pivot irrigation have been revolutionary. Nowhere is that more visible than in the United States where widespread conversion to center pivot irrigation has transformed agriculture and the landscape.  By using mechanized irrigation equipment, U.S. growers increased their revenue and their crop yields. Farmers grow more food with less water while being released from the drudgery of conventional irrigation methods and putting their labor to better use.

On a global scale, aggressive investments in irrigation, hybrid seeds, and fertilizer during the past 50 years have brought famine and poverty under control in Latin America, China, and South Asia. Yet most of Sub-Saharan Africa has made little progress during this same time period.  Limited investment in technology and infrastructure resulted in limited commercial farming in the region. 

Throughout Sub-Saharan Africa, more than 90 percent of the farmers are subsistence farmers. They spend half their annual incomes on food, leaving little money for education, health, and housing needs. (In contrast, only 6 percent of U.S. annual household income is spent on food). 

An exception is South Africa where Valley_® introduced center pivots in the 1970s. In South Africa, pivots are used primarily by medium and large commercial farmers, who have experienced tremendous success. The same drivers of this success can serve as a model for small growers, and Valley Irrigation is working to develop a model of shared pivots for smallholder farmers.

Many African smallholder farmers remain poor because they depend on unreliable rainfall, making them vulnerable to drought and climate change. Although these disadvantages could be completely eliminated by irrigation, center pivots are often cited as too expensive for Africa’s farmers. 

However, if small farmers share a center pivot, the cost drops dramatically. Figures 1 and 2 demonstrate the dramatic reduction in cost of a center pivot once the radius of the field exceeds 300 meters.

Figure 1

Figure 2

An association of smallholder farmers, or a large commercial producer serving as an irrigation and crop marketing provider, can own and operate the center pivot in cooperation with the smallholder farmers. This approach puts precise, efficient irrigation technology into the hands of small farmers, and the impact on farm production is dramatic because water is available where and when the crop requires it.  

Widespread use of this model could turn subsistence farmers into profitable commercial farmers by increasing yield and empowering farm workers. That's Valley, leading the way and feeding the world!

Smart Irrigation Month | by Kelly Downing

July has been Smart Irrigation Month. I don’t know about you, but I completely missed all of the parades, fireworks displays, and benefit concerts in its honor. I didn’t even see the telethon. Like most of you, I was too busy trying to irrigate efficiently! 

No, this observation gets lost in everything else going on in our busy world. There is value in thinking about the concept, however. Often we get so wrapped up in keeping up with the day-to-day challenges of our operations that we get a little tunnel vision. It is easy to focus so intently on the critical, immediate issues in front of us that we temporarily forget about larger, more general topics. 

The current drought conditions faced by farmers in many areas of the U.S. provide a constant reminder that “smart irrigation” is not just a catchy phrase or a “cause of the day.” It is becoming increasingly obvious that this is, and will be, a critical concept for the future of agriculture. Not just in western states, where the climate is arid, and not just in “traditional” irrigation areas. 

Competition for water continues to increase. Not just competition between farmers; not just competition between states; not just competition between agriculture and industry; not just competition between agriculture and domestic or urban users (irrigating vs. drinking water). We increasingly see competition between agriculture and environmental interests, in the interest of protecting wildlife habitat, endangered or at-risk animal and plant populations. There is also increasing interest in how farm practices hundreds of miles away influence coastal and marine environments, like Chesapeake Bay and the Gulf of Mexico. 

This competition is not limited to volume of water used, either. Protecting and improving water quality is more important now than ever. Water quality will continue to be a hot topic in our cultural, political, regulatory and economic discussions. Let us not forget that quality is a broad term. It can include physical (temperature, particle transport) as well as chemical (nutrient content, pesticides in solution) components. 

All of these issues, especially combined with the constant pressure to increase food production and maintain profitability, make it imperative to find and implement the “smartest” irrigation practices possible. We need to work to increase both effectiveness and efficiency of irrigation. To me, “effectiveness” means that we apply every ounce of water the crop needs to achieve our goals, in the correct amounts and at the correct times. “Efficiency” means we apply not an ounce more than that, with the minimum possible energy, labor and cost. 

I mention all these things not to create alarm, but to spur thought and discussion. I think the great majority of producers are conscientious about all these issues, and good managers include them in their systems as a matter of course. I also think we would all be better served if we keep the discussions among stakeholders (ag, municipal, industrial, environmental) to a reasoned, rational tone, with everyone committed to working together. Sometimes we forget this part. 

Jeremy Baltz's rice field

Of course you knew this would come up eventually, but here it is: one way we are trying to “increase our irrigation IQ” is with our Circles for Rice project. Last week, I had the chance to stop by Jeremy Baltz’s field in Arkansas. His pivot rice looks quite good so far, while he has applied just about half of the water used on a nearby flood field. It will be exciting to see how the rest of the season goes, as we continue to study this “smart irrigation” practice. 

You probably remember the old joke: “It’s hard to remember that your original goal was to drain the swamp when you are up to your {rear end} in alligators.” That is analogous to the situation we often find ourselves in: our goal is to increase efficiency, effectiveness, and profit, but our immediate concern is keeping the crop going and meeting the day-to-day pressures of farming. So, as you fight off the daily “alligators,” try to grab an occasional bucket of swamp water and throw it over your shoulder! 

I will be at the field days hosted by RiceTec, in Harrisonburg, and the University of Arkansas, in Stuttgart, next week. I hope to see you there. Stay safe!

Valley - The Best Value

Originally published in PivotPoint Spring 2011.

Growers are famous for being shrewd consumers. With every dollar hard earned from real, physical labor, they’re not going to waste it. The bottom line is value. Growers find that value in a variety of ways when they invest in Valley_® equipment. That’s made Valley the leader in center pivot and linear irrigation, and their products the first choice of growers all across the country.

According to Brad Johnson, owner of BRJ Farms near Holdrege, Nebraska, the durability and reliability of a Valley is what gives him peace of mind. With a large number of soybean, corn, and seed corn acres, Johnson knows the vital role reliable irrigation equipment plays. “I’ve been around pivots for a long time, and I’ve chosen Valley center pivots for almost all of my ground. My father and I both trust Valley because we just don’t have breakdowns. We just don’t. These are long-lasting pivots and they’re made well,” he shared.

Johnson understands value. Valley center pivots are engineered, constructed, and field-tested to handle growers’ varying and challenging operating conditions. They are known to have the most durable structure in the market place and have a longer life span than other product brands proven by independent tests. Finally, they command the highest resale value.

Brad’s Valley dealer, Central Valley Irrigation in Holdrege, Nebraska, likes to show growers in his area that the value of Valley machines starts from the ground up. “I like to take growers out to the manufacturing facility about an hour away from us. They see that these structures are made in an environment that is clean and professional. They see the steel when it comes out on a trailer. This is where it starts. Valley is committed to building things right, and that’s where durability begins.” He also shows growers who visit his dealership the stress tests that Valley has published on their structures. “When we talk about the durability of our structures, it’s important that they see the stress tests that have been done to prove the value of this. Valmont Irrigation really invests in these structures.”

Chuck Messersmith of Western Valley Irrigation in Alliance, Nebraska, believes the structural integrity of Valley machines is key. “The overall structure and the strength in engineering in the physical structure of Valley machines are a big part of the value for growers,” he explained.

Messersmith also pointed out that the clean lines and integrity of the span design is also an important detail he points out to growers. “The shape of the pipeline itself, the crown, shows a superior design. The structure is supported uniformly and the stress is more evenly distributed. When customers want to know why Valley machines have a longer life than other machines, I tell them that this is part of the reason behind that long life span.”

Custom-designed pipes and trussing, along with forged truss rods with a larger root radius and head diameter add to this strength – and to the long term value of Valley machines. Welded sprinkler outlets provide the most durable option when compared to other methods and also protect against a loss of water pressure, vital to precision water applications.

Well-made tower control boxes are another feature that adds value to Valley equipment. The main base component of the control box is made of steel rather than plastic. Other machine brands use plastic. All switches and control mechanisms are mounted on steel in Valley tower control boxes., and that increases the tolerance for clearance in the moving parts. The steel helps keep the alignment where it should be and is more durable.

The Valley gearbox is the pinnacle of the Valley drive train and yet another feature that proves industry leadership. It is designed and manufactured at Valmont Irrigation’s manufacturing facility in Valley, Nebraska, so that quality can be ensured. Messersmith, of Western Valley Irrigation, says “The truth about the gearbox is that you don’t have to sell it to growers – they already know that Valley gearboxes are better. They already know the difference!”

Finally, legendary Valley service is a big part of the overall value of a Valley machine to growers, according to Johnson of BRJ Farms. “Service is a huge one for me. The response time from my Valley dealer, Central Valley Irrigation, is amazing. They are there within an hour. It is fixed correctly the first time. The winter program is also awesome. They went through each pivot of mine last year and I went without any service calls during the irrigation season. They are just dependable – the machines and the company.”

Valley dealers are known to have a true caring for their customers. “Our customers are not just somebody we hope will buy something from us, but someone we can work with hand in hand to make irrigation work,” added Messersmith of Western Valley Irrigation.

Sprinkler Models for Center Pivots and Linears

Originally posted January 2011.

There are two types of sprinkler models used for center pivot and linear equipment: fixed spray and rotating spray. Both sprinkler types have a wear plate mounted directly below the nozzle (orifice), which discharges the water and creates a 360° water pattern. Fixed sprays have no moving parts because the wear plate is fixed. A rotating spray wear plate rotates either fast or slow, depending on the sprinkler model.

Water Patterns and Runoff

Rotating sprays produce a large wetted diameter (50' to 70') that creates a low-intensity water pattern; this is a major advantage of rotating sprays. This type of sprinkler works very well on medium to heavy soil types and reduces water runoff. Fixed sprays have a wetted diameter of 15' to 40'. This type of sprinkler works well on light soils where runoff may not be a big issue.

Plate Design

There are a variety of plate designs available to you that can very the droplet size of the water pattern; various designs are available for both rotating and fixed sprinkler types. By selecting a plate that produces smaller water droplets, you can also reduce the water pattern intensity. Smaller water droplets can easily lead to lower application efficiencies from evaporation and wind drift losses. Please note that climate conditions must be considered in the plate selection.

Fixed spray and rotating spray sprinklers are designed to operate at a low pressure in order to minimize energy (pumping) costs. Design operating pressure for fixed sprays is 6 to 30 PSI and pressure for rotating sprays is 10 to 30 PSI.

Circles of Green in the Toasty Northwest | by Jill Zwiener

A couple weeks ago, I had the chance to visit Washington state and Oregon. The toasty 105° temps kept me warm and the green circles from the Valley_® center pivots that were seen in almost every direction kept me smiling! It made me think of our billboard on Highway 275 just outside Valley, NE, which reads, “This is Valley Country.” There were Valley machines everywhere! These growers in the Northwest sure know what they’re doing!

Valley pivot with Precision Corner arm

We met with over 15 growers, and there was one thing they all had in common – their love for Valley. There were two products in particular that they raved about….VRI (Variable Rate Irrigation) and BaseStation (remote monitoring and control of center pivots). When discussing BaseStation, we heard the same message over and over….“Now that I have it, I’ll never go back!”

Grower using Valley BaseStation 

We saw a variety of crops – potatoes, wheat, corn, alfalfa, beans, onions, rhubarb, asparagus, radish, and grass seed. The variety of crops and the varying landscape were fun to see.

If you’re ever in the Pasco, WA, area, you need to stop by the Country Mercantile for a little pit stop. It’s definitely my kind of place! They have homemade ice cream, chocolates, fresh fruit and canned/jarred goodies. And, my favorite part had to be the free salsa samples! If only I wasn’t getting on a plane the next day I would have bought a few tubs of it to enjoy! But don’t worry…I didn’t leave hungry. I had a monster ice cream shake which I couldn’t even finish…now, if you know me, that’s a rarity!

The best chocolate shake EVER!

Fun fact: 
Workers in the area harvest asparagus by hand. They use a knife, cut the spear, and fill their buckets with the superfood. They often work in the dark hours of the early morning to beat the heat.

On Location: Grower Trip to Washington | by Michelle Stolte

Greetings from lovely, steamy Pasco, WA. Last week, my co-worker, Jill, and I were fortunate enough to have the opportunity to visit the Pasco area to check out various fields, talk with growers, and see the different irrigation equipment in use in the Northwest. I am happy to say that many growers in this part of the country have realized the value and potential of center pivot irrigation and are using this equipment to make their operations as profitable as possible. As for our Valley_® customers, besides being amazingly hospitable, they are very progressive, adopting the use of Variable Rate Irrigation (VRI) and the BaseStation remote management tool. 

I periodically get to travel to farm fields in different parts of the USA (even to fields in a select few countries), but I have never seen anything like what I saw on this trip. The diversity of crops is extremely impressive, with crops varying from onions to mint to asparagus to lavender. I don’t remember the last time I had to constantly ask “And what is that crop?” Coming from Nebraska, you learn to recognize corn and soybeans pretty quickly, but not a whole lot more. 

I have also come to realize that maybe I am becoming a bit of an agriculture geek, because I think the scenery out here is absolutely beautiful. This area of Washington is very dry, averaging 5-7 inches (130-180 mm) of rain a year, but when you look out at the hills and see green circles in a sea of dry, brown land, it is a beautiful sight (pictured above). And unlike the majority of Nebraska, these circles are NOT on flat ground. The terrain is rolling, so you may only see half of the circles coming down the front side of the hill while the other half is on the back side. If you have ever see Salvador Dali’s painting “The Persistence of Memory,” which features melting clocks, that is exactly what the center pivot circles out here reminded me of. This picture isn’t the best as the triple digit temperatures created a bit of a haze, but hopefully you can at least get the idea. 

Many thanks to our tour guides, Shane Shiplet and Jonah Lindeman, as well as to our local dealer, Valmont Northwest. This has been a great, educational experience for me!

Off We Go! | by Kelly Downing

Summer is finally here! Almost to the exact day, temperatures around the old homestead have warmed up into the summertime range (90°+, or 32°+ for our metric friends). All of us who worked through the significant drought last year are a little skittish about what the summer might bring. This spring has been relatively cool and wet around my house, but I can’t help thinking back to last year and how quickly (and thoroughly) things deteriorated in July and August. The latest drought index map (see below) shows that the drought is “officially” over in the eastern part of the country, but is still very real to my West and South. Being right on the border, I am certainly not getting cocky!



Last week I got to visit SE Missouri and NE Arkansas. Our cooperator near Pocahontas, Arkansas, has some nice-looking rice (photo below), so we will see what this summer brings. We have begun to shift our focus a little in the Circles for Rice program. We really seem to have shown that this system works, so we now work to simply support people who want to try growing rice with pivots, as opposed to creating and promoting demonstration plots.

With the current economic issues at work, there still seems to be pressure for growers to shift acreage to other crops, at least here in the U.S. and in Brazil. In other areas, especially Africa, the situation is a bit different, and we have been working with several growers developing rice projects using pivots as the source of irrigation. These are, generally, relatively large projects, so they take quite a bit of time to get up and running. However, we will bring you news and progress reports as they develop.

A couple nights ago, I watched a television special on the Discovery Channel: Nik Walenda walked across the Grand Canyon on a cable, suspended 1500’ above the river below, with no tether or safety harness. He kind of reminded me of a farmer. He did a tremendous job of preparing, so that it really did look easy. Not easy enough for me to try it, though!

How many of you find yourselves in similar circumstances — balancing a lot of factors both known (crop production costs, machinery issues) and unknown (the vagaries of summer weather like severe storms or drought, crop price fluctuations)? It sometimes seems like the best approach is just what he did — prepare as well as we can, then just keep putting one foot in front of the other, until we get through the current season.

The good news is, we ARE into another summer, firmly seated in the rhythm of the crop growing season. Somehow, I think that helps farmers cope with some of the other peripheral issues that pop up. There is something neat about growing a crop, and it brings us back to earth in a lot of ways. We might not know how the future is going to work out, but we do know how to recognize what is happening in our fields, and what to do about it. That process gives keeps us in our comfort zone; it allows us to focus on what we enjoy doing, and doing well. So, I encourage you to stay safe and have a great growing season. Keep putting one foot in front of the other. Stay in touch, and let us know how things are going in your neck of the woods (or prairies!).

Simple vs. Easy | by Kelly Downing

I (and I am sure many others) often blur the meanings of the terms “simple” and “easy.” We are all familiar with the adage “the best plan is a simple plan." I think most people inherently find this principle sound. Where it falls apart is the reality that simple does not equate with easy. There are many activities that are relatively complex, but we view as being easy. To use a couple of extreme examples, things like tying your shoes, riding a bicycle, or brushing your teeth require some relatively complex motor skills. Most of the time, though, they are considered easy to do (except with a broken wrist!). On the other hand, if we consider Omaha Beach on D-Day, the strategy for our heroes was relatively simple—jump from the landing craft, advance past the beach, and continue inland. Nothing could be farther from easy.

I was reminded of this difference recently while visiting a new rice operation. This was a brand-new development, growing rice in a desert area never before tilled. In theory, the process is relatively simple: plant, fertilize, irrigate, and control weeds. In practice, this is a daunting challenge. Our friends have made a lot of progress, but there are problems. As we toured the field and looked at conditions, I was reminded how difficult it is to start an entirely new enterprise like this. Building the infrastructure to supply water, installing the pivots, and getting the crop in the ground required a big investment in money, effort, and will.

Nevertheless, they were able to build the water supply system, install the irrigation equipment, and get the crop planted. They also have been diligent in irrigating and doing various field operations—herbicide application, fertilizing, etc. Unfortunately, a couple of “simple” things are causing some big headaches. The primary issue is weed control. As we have found in other areas, desert soils can grow many things quite well, if irrigated. This includes weeds, of course. In fact, with great water and fertility, they grow like… well, like weeds! Now the weeds have almost taken over the crop. The farm operators are working to battle this issue, but it is a tough slog. They decided to hand-weed and continue the fight.

As we all realize, there are a few factors that contribute to this issue. One is equipment, as they use hand-held sprayers to apply herbicide. This really limits the uniformity, concentration, and timeliness of the herbicide applications. Probably the biggest factor, though, was the limited number of products available. Relying on only one or two herbicides can really limit options. It appears that, in this instance, they “brought a knife to a gunfight.”

Fortunately, these are bright, motivated people, and they are working diligently to solve their problems. I am confident they will find and implement the procedures necessary to succeed with future crops. It will not be “easy,” but then, how many worthwhile accomplishments are? We will certainly revisit this project in the future, and I am sure there will be better news to report. It is important to remember that the first time any of us try something new, we never produce our best results. So, even when things look daunting early, we observe, learn and adapt to achieve success.

Now, I just need to remember these principles the next time I hear some goober (like myself) look at a situation from the outside and ignorantly say “It’s simple. All you need to do is…” Yeah, it may be simple, but that doesn’t mean easy. If it was easy, anybody could do it!

So, as you go out and face the challenges of your own operation, keep your chin up and keep fighting the good fight. It is a new growing season, and already there have been unique challenges in different locations. Keep working the situation, make good decisions and do what you can. Have a safe and prosperous growing season, and stay in touch!

Farming is in the Trail Blood

Originally published in Spring 2013 edition of PivotPoint.

Today, the two men and their wives work together very closely. Eventually, Rocky and Terrie plan to step back, taking more time off and traveling. For now, though, it is truly a family affair, as Rocky teaches Rusty all the nuances of farming the land, even as Rusty uses technology to get more out of that land with precision planning. meanwhile, Terrie and Jennifer work together on the books.

“We’ll be sitting around the dinner table at night with the kids, talking business,” says Rocky. “We make all of our decisions jointly. With us, it’s all family – all business.”

Working together to save money

Farming 2,200 acres in the hills and valleys of Idaho presents some challenges, one of which is how to irrigate their sugar beets, alfalfa, and winter wheat. They have always irrigated their land, mostly with hand lines, which requires a lot of labor.

Rocky explains, “The whole goal is to save on labor, and while pivots aren’t totally labor-free, they’re much better than hand line irrigation. It takes 10 guys to work with hand lines, but only three to work with pivots.”

The Trails decided to start the switch to pivot irrigation about 13 years ago. Valley dealer JTS Farm Store is about five miles away from Trail Farms and the Trails knew the owners, Jim and Lea Ann Schraeder, so it made sense to work with them.

Lea Ann Schraeder says, “Rock and Rusty are just great guys to work with. They’re very business-oriented, so they require a quality product and good service. Just because we’re close by doesn’t mean we’d keep their business if we didn’t come through for them.” Including two soon-to-be-delivered new pivots, the Trails have nine Valley pivots, covering nearly half of their land.

“Fifteen years ago, some of our land wasn’t considered suitable for pivots at all,” explains Rocky, “but by adapting to different water sources, we installed pivots on that land, and it’s working well. Using sprinklers on beets while they’re germinating is so much better,” Rocky says. “Pivots are very flexible for that, and hand lines really aren’t.”

”We were one of the first operations to use a reverse swing arm, which moves counter clockwise,” says Rusty.

The Trails keep up with technology when it makes sense. For example, they use auto-steer on their implements and they have Trackers on their irrigation systems, with all alerts going to Rusty’s smart phone. They’re also looking into purchasing a Valley BaseStation2-SM.

Will there be a fourth generation Trail farmer?

Rusty’s son Parker goes out on the tractors with them every year and loves it. “He says he wants to be a farmer, too,” says Rusty with a smile. “Of course, he’s eight, so we’ll have to wait and see.”

Quickstart Intelligence: Custom-built Precision Irrigation from the Start

Originally published in Spring 2013 edition of PivotPoint.

Valley_® now has a way to take the learning curve out of the equation with VRI QuickStart. QuickStart is a prescription for Speed Control, custom-developed specifically for the field the machine is irrigating. It’s uploaded into the control panel before installation on new machines, or it can be uploaded to any existing VRI control panels and TrackNET™ products.

“Basically, growers can hit the ground running with the QuickStart Prescription,” says VRI Product Manager Cole Fredrick.


HERE'S HOW IT WORKS:

1. A Valley dealer works with the grower to determine the ideal water application across the irrigated land.
2. Based on this information, the Valley VRI Team develops the prescription and uploads it into a new control panel before it’s shipped for installation. If it’s an existing panel, they can upload the prescription either via direct upload or TrackNET.
3. The grower can start using VRI right away.

“We’ll load the prescription directly into the control panel, so there’s no lag time between when the control panel is installed and when the VRI is functional. We can also develop prescriptions for TrackNET products and load them wirelessly over the internet,” continues Fredrick.

From the start, growers can take full advantage of VRI technologies.


WHAT IS VARIABLE RATE IRRIGATION?

VRI Speed Control
VRI QuickStart makes VRI Speed Control available the instant the prescription is uploaded. 
Speed Control allows growers to:

• Speed up or slow down the pivot in two-degree increments to achieve the right application depth for varying field properties and conditions
• Use a new or existing sprinkler package
• Use with TrackerLT or TrackerPro
• Use the Pro2 or Select2 control panel

VRI Zone Control
Zone Control allows growers to:

• Pulse control valves on/off along any individual management zone to achieve the right application depth for varying field conditions and properties.
• Use on/off control for specific areas in the field that may not need water, like ditches, canals, or wet areas
• Use a new or existing sprinkler package
• Easy plug-and-play capability

“We have had discussions about what would make getting the benefits of VRI to growers more quickly and in an even simpler way,” explains Fredrick. “That’s where VRI QuickStart began. It’s a Valley exclusive and we think it’s going to be very beneficial for the grower.”
