The latest report from USDA’s Economic Research Service on “Recent Adoption of Precision Agriculture” is about five years behind the times.

The report heralds that agriculture is “On the Doorstep of the Information Age” – using mostly information from 2005-06. According to the report, “recent data from the Agricultural Resource Management Survey (ARMS) show that use of yield monitors, often a first step in using precision technology for grain crop producers, has grown most rapidly, and was used on 40-45 percent of corn and soybean acres in 2005-06.”

The information for the study relies primarily on 2001 and 2005 surveys of corn, 2002 and 2006 surveys of soybeans, and 2004 and 2009 surveys of winter wheat – “the 2010 corn survey results were not yet available when this report was prepared” – which was this year. While there is some interesting data in the report, it is woefully out of date. Just think, if the survey had included questions about the use of smartphones on the farm, it would have been zero, since it was January 2007 before the first iPhone was introduced – and we’re now on the fifth generation. Point being, the adoption of all types of new technology has literally skyrocketed in the last five years.

Be that as it may, the most interesting findings in the report show that precision really does pay for farmers. For example, they found that corn and soybean yields were significantly higher for farmers using yield monitors compared to those who did not. In addition, farmers using yield monitors had lower per-acre fuel expenses. Average fuel expenses were lower, per acre, for farmers using variable-rate technologies for corn and soybean fertilizer application, as were soybean fuel expenses for guidance systems adopters and adopters of GPS mapping and variable-rate fertilizer equipment had higher yields for both corn and soybeans.

With all this new technology, you would think that USDA could find a way to gather, compile and disseminate information a little bit faster.

Precision agriculture is playing a much larger role in helping potato growers become more sustainable, according to a recent story in Spudman.

Bruce Crapo, a grower of 6,000 acres of commercial potatoes and 2,000 acres of seed potatoes in Idaho, is a good example of how the average potato farmer looks at precision agriculture – he uses technology to reduce costs, increase output and improve profits.

Crapo isn’t thrilled at the cost of high-tech equipment such as GPS-guided tractors, but he knows it’s saving him money and there’s no way he can turn back now.

“There is a substantial initial cost involved,” Crapo said. “But I also know it is saving me money. What do you do? Go back to what you were doing before? That’s not an option.”

Crapo, who uses Global Positioning System (GPS) technology on all his planters and harvesters, said the latest precision ag technology has taken farming to a different level.

“It’s light years ahead of what it was when we were doing it by hand,” he said. “We’re not going to go back to not using it, but we are wincing a little at the cost.”

Precision agriculture can loosely be defined as using new technologies such as GPS, sensors, variable rate application equipment and aerial or satellite images to make farming easier and more profitable.

Simply put, precision agriculture can help farmers improve their margins by decreasing their operating costs.

Idaho farmer Robert Blair, owner of PineCreek Precision, says the biggest benefit of precision farming is that it gives producers the ability to manage their farm on a production zone basis rather than a whole field basis. This shift, he said, allows farmers to save time and money and helps them offset the rising cost of chemicals, nutrients, fuel and fertilizer.

Blair uses a wide array of precision agriculture techniques on his 1,500-acre farm and said the technology is saving him tens of thousands of dollars every year.

Effective control of Southern root knot nematode looks promising with the use of GPS-controlled, variable-rate applications of soil fumigants, according to University of Arizona researchers, as reported by Western Farm Press.

Field trials conducted from 2006 to 2010 tabulated information gathered by global positioning systems and variable rate technology, including the electrical conductivity-based Veris 3100 and EM38 sensors for on-the-go soil mapping, plus harvest yield mapping data.

This technology illustrates that nematicide applications can be applied sparingly in some cases while maintaining good nematode control and trimming chemical costs.

The grower cooperator field trials included six studies with the nematicide Telone II applied at pre-plant in cotton and corn in central and southwestern Arizona conducted by University of Arizona (UA) researchers Randy Norton, Tim Hatch, Mike McClure, and Pedro Andrade.

Norton, UA regional extension cotton specialist based in Safford, shared the findings during the 71^st annual Cotton Disease Council meeting at the 2011 Beltwide Cotton Conferences in Atlanta, Ga., in January.

Norton labeled the RKN as the No. 1 nematode species threat in Arizona. The microscopic roundworm damages crops by attacking the young tap and secondary roots which stimulates the production of galls. Galls interfere with the ability of the roots to absorb water and nutrients, and allow other disease-producing organisms to enter the plant.

Arizona hotspots for RKNs include the Coolidge, Casa Grande, Florence, and Buckeye areas in central Arizona and the Bonita area in the Sulphur Springs Valley in southeastern Arizona.

In cotton, the RKN is responsible for a 5 percent lint yield reduction on average across the Cotton Belt, Norton says. Five gallons is the standard Telone II application rate in Arizona to maintain cotton yields in RKN-infected fields.

Ag Leader Technology officially released the North American Wheat algorithm for OptRx during the Iowa Power Farming Show in Des Moines, Iowa this week. OptRx is a crop sensor used for mapping, data collection and real-time variable rate nitrogen application.

To learn more about how OptRx worked, I spent some time with Mike Olson, North American Sales Manager for Ag Leader, during the show. He said releasing this crop sensor was the next logical step for them because there is a huge demand in both North America as well as globally for nitrogen for wheat.

Applying the right amount of nitrogen at the right time is very important for wheat so you don’t have issues like lodging, and you get better crop stand. “So if we can monitor crop health as you go through the field and apply nitrogen based on it, we can use nitrogen more wisely across the field and give you a better overall stand,” explained Olson.

Last year, Ag Leader released OptRx crop sensor for corn. Olson said that in the past two years, the Midwest has seen very wet springs and crop variability has been very, very high. This has caused a lot of nitrogen leeching. Growers who used OptRx last year, on average, saw a $25 per acre improvement over not having the crop sensor and using a flat rate application.

Since real-time variable rate nitrogen applications in the field, such as OptRx are pretty new technologies, I asked Olson what the three most common questions were from growers, He said, “What’s the technology? What equipment do I need? and What are the benefits?” You can get detailed answers to these questions in the video below.

The 2011 season is fast approaching so now is the time to purchase your technology. Olson said that both the OptRx crop sensor for wheat and corn are now available and the has team members standing by to give growers the 411 on the technologies. In addition, his team members can help them get set up and ready to go so when the window of opportunity is available to apply nitrogen, they’re ready to go.

For wheat growers who normally top-dress nitrogen, the use of crop sensors could boost yields and reduce over or under application.

Today, Ag Leader Technology, Inc., a leader in the development of precision farming solutions, announced the release of the North American Wheat algorithm for OptRx, a crop sensor used for mapping, data collection and real-time variable rate nitrogen application. OptRx crop sensors determine a vegetative index reference value based on a plant with sufficient nitrogen and prescribe nitrogen rates based on plants’ crop vigor, taking into account field variability and crop conditions.

“Using OptRx for nitrogen application in wheat can help prevent yield loss commonly due to overapplication, especially in early growth stages,” says Roger Zielke, Product Manager. “Another major factor that OptRx can help account for is the variability in organic matter within fields. Variable rate nitrogen application with OptRx can compensate for these differences in organic matter, and our field trials have shown that it will help maximize profit potential by delivering the right amount of nitrogen to the right plant.”

OptRx can help improve nitrogen efficiency by scanning and measuring the impact of growing conditions on a plant, ultimately helping growers improve environmental stewardship and maximize profit potential. Nitrogen application on wheat can occur anytime between tillering and stem elongation, and any top-dress applicator can be used with OptRx for nitrogen application. Because OptRx uses a light-sensing technology that is not dependent on ambient light, OptRx can be used to apply nitrogen, whenever optimum conditions are available day or night. OptRx crop sensors are also available for nitrogen application in corn.

Had the pleasure this week of talking to a great guy, George Ropp of RCMS Consulting, who is 74 years young and still helping farmers—use computer software, no less.

Ropp, of Van Wert, Ohio, decided to get into GPS work after retiring from the county extension service in the early 1990s. “I started grid soil sampling fields for the local elevator, and using the simple software we had back then,” he says. “As the years went on, seeing huge changes in software, I was unsure I would find the capabilities I needed, until I found Ag Leader’s SMS software about six or seven years ago.”

Not only did Ropp become a fan, he actually built a good consulting business by selling and training growers and retailers on using SMS Advanced, Basic and Mobile software. “I’ve probably sold 50 to 60 copies of the software, and some mobile devices and other equipment, too.”

Ropp takes great pride in helping his clients, often spending a half-day or more with software set up and initial training. “I want to make sure it is set up right, and that the customer is happy,” he says. Now he holds about 4 or 5 training session during winter to keep his customers updated and answer questions.

“More farmers and retailers are getting into variable-rate fertilizer applications and want a software that can handle the necessary equations and building prescription maps. SMS is really easy to use for such operations, and it is really driving software buying” he adds.

Other popular tasks that Ropp is training customers to do are adding layers of soil test data as well as adding soil type maps from NRCS. “I’ve actually created ‘cheat sheets’ on many of these topics, so I don’t have to repeat myself so often,” he laughs.

What’s next? “Well a vacation right now,” he says. But seriously, he sees growing interest in farmers thinking about adding aerial imagery to their field data layers. “I suspect in another year this will greatly increase in popularity.”

His clients greatly value his training expertise on SMS software. “Well, they must, because they keep calling me for advice,” he chuckles. “And I really appreciate the service I get from the software support team at Ag Leader, as even I get stuck every now and then. They are really helpful.”

The precision irrigation from Valley has now teamed up with the variable-rate precision data services of CropMetrics.

This agreement creates an alignment of Valley Irrigation dealers with the latest in agronomic technology to provide growers true precision irrigation with center pivots. Valley Irrigation with VRI Zone Control, and CropMetrics with automated agronomic VRI prescription services, are also proud to announce their AE50 awards for 2011 as a top 50 innovative new product produced in 2010.

“Precision Irrigation starts with building a precise water management plan,” said Craig Malsam, Valmont Irrigation Vice President of Engineering. “Applying the optimum level of water and nutrients through a center pivot is more important than ever. We’re excited to be the first in our industry to supply a whole new dimension of precision irrigation through our agreement with CropMetrics and their optimization service available through our Valley dealers.”

“As our single most valuable natural resource, applying excess water is an unnecessary cost. Apply too little water, and yield potential is now lost as well. Our solution is to optimally apply water specific to soil type,” said Nick Emanuel, CropMetrics President. “We’re excited to work with Valley dealers and offer Valley customers the ability to take Precision Agriculture to the next level with our unique precision agronomic solutions and data services.”

CropMetrics specializes in full-service data collection, processing, and advanced yield analysis. The company supplies all proprietary web-based software and large-scale data processing so agronomists, crop consultants, ag retailers and Precision Ag specialists can focus on providing fast, reliable and profitable Precision Ag programs for variable rate irrigation, nitrogen and seeding.

Valley Irrigation VRI Zone Control provides individual sprinkler or span control and is fully compatible with all new and existing center pivots equipped with the Valley Irrigation Pro2 control panel. The Pro2 panel uses power line communication to remotely manage as many as 30 VRI Zone Control units. This allows each individual control unit to be easily positioned at any point along the pivot span. Because the new VRI Zone Control utilizes the on-board computing power of the Valley Irrigation Pro2 panel in combination with power line communication, the added VRI equipment cost is very reasonable.

“We believe that combining Valley Irrigation control technology with CropMetrics precision services is the future of mechanized irrigation,” said Malsam. “Producers with pivot irrigation have always been able to control how much water is applied to a field. But this technology allows producers to control how much water, fertilizer and other crop management products are variably applied based on precise agronomic data.”

The AE50 awards will be announced during a presentation at the American Society of Agricultural and Biological Engineers (ASABE) Agricultural Equipment Technology Conference (AETC) in Atlanta, Ga. on January 6 as part of the AG CONNECT Expo. Representatives from CropMetrics and Valley Irrigation will be available to demonstrate the new VRI technology in the Valley Irrigation booth at AG CONNECT.

This past week, I caught up with Matt Darr, Iowa State University ag engineer and precision farming guru, to chat with him about this past year in precision agriculture.

“We’ve said for a few years now that ‘accuracy is addictive.’ Well farmers are proving that as this has been a year driven by higher precision—a move to more RTK accuracy.”

The big deal. Darr cited the widespread nature of expanding RTK networks, both public and privately owned. “These networks are pushing us towards RTK becoming a standard commodity, which will help drive down the costs and give more growers the potential to achieve high-end accuracy. And that is a big deal.”

The CORS network has had a strong run over the past three years. Indiana is now online as the most recent, along with CORS networks in Iowa, Ohio, Michigan, Wisconsin, Minnesota and Missouri. “I see this growth slowing down, but we’ll continue to see greater stabilization and improvement in the signals,” Darr says.

In the private sector, we’re seeing greater expansion from Trimble’s VRS network and from John Deere’s StarFire 450 MHz radio system, as well as other smaller companies building systems across the Midwest.

Crop sensing. Another big push is on to figure out how to use active crop sensing to provide financial benefit. “With the addition of Ag Leader’s OptRx system, along with the Greenseeker from Trimble and CropSpec from Topcon, growers have the potential to unlock another area of profitability. It’s not as simple as auto guidance, and it may not work for everyone,” Darr says.

This technology offers a natural fit in wheat, since growers are used to topdressing in the spring. “Anytime you can automate N applications, you’re looking at both economic and environmental benefits. A reduction in the over-application of N is a big deal,” Darr says.

“The challenge for Midwest corn growers is that not every producer uses sidedressed N when corn is 12 to 18 inches tall, which is where this technology needs to be used. So you’re asking growers to change production practices as well as adopt new technology, so these challenges will slow adoption. But it offers huge potential,” he adds.

The future. “If you look back 4 or 5 years, and think about the automation technology that has come out—from auto swath to auto steer—all the easy things, relatively speaking, have been automated. Future automation gets tougher. We now need to circle back to data and press that information into greater knowledge. That’s what we’re after. We must gain knowledge from all this data to improve our operations,” he says.

The Alabama Precision Ag team has compiled three good publications on automatic section control (ASC) for sprayers, planters and spreaders.

Automatic section control (ASC) has been one of the most adopted precision ag technologies in recent years. This technology has the ability to save producers on input costs by minimizing application overlap at headlands, point rows, or other odd-shaped areas of fields. Our research suggests a 2% to nearly 30% savings in fields when using ASC and guidance technology. Further, ASC can improve on-farm environmental stewardship by eliminating application in environmentally sensitive areas (e.g. grassed waterways, buffer strips, etc) or outside field boundaries. Frequent comments by those who have adopted ASC is that they want to implement on all their application technology (sprayer, planter, side-dress unit, etc.) and it reduces fatigue over long work days by automating the on and off of sections.

To help producers and others interested in ASC, the Alabama Precision Ag Team has put together 3 publications providing a general overview of ASC, needed components, and company information for planters, sprayers and spinner spreaders. Many times the expense to purchase ASC for a machine is relatively small compared to the savings it provides on crop inputs. We hope this information can help those looking to purchase ASC during this off season. Please let us know if you have any questions or we can assist in anyway.

The following provides direct links to each of these publications.

Fertilizer production costs will be substantially higher in 2011 than they’ve been for the past couple of years. When you look at the numbers, remember that commodity prices also have increased significantly.

If you are a shrewd marketer, you have taken advantage of crop pricing opportunities that will help offset the higher production costs. You may still be able to find a few holiday bargains for pre-paid fertilizer, however, most of the good deals ended in November. Following these tips can help you achieve a profitable fertilizer program for 2011

10 Tips for Getting the Most from Your Fertilizer Investment

• Follow a good soil testing program to know macro and micronutrient levels.
• Use the most efficient methods to apply phosphorus (starter or strip-till application) and timing options/methods/sources for nitrogen.
• Take deep soil samples for residual nitrate to fine-tune N rates.
• Set realistic yield goals. Expected yield is the major factor in determining the nitrogen rate for corn. Use a proven five-year average corn yield plus 5% (to account for hybrid and management improvements).
• Credit N from previous crop residue or legume crops. Soil tests will not show legume or crop residue credits as the residue or nodules must break down during the growing season. Credit N for corn after soybean, sugar beet, alfalfa, and dry beans.
• Value and use manure sources properly. Manure is an excellent nutrient source for nitrogen, phosphorus, and micronutrients.
• Not all fertilizer recommendations are the same. UNL fertilizer recommendations may seem conservative compared to some commercial labs. UNL suggestions are based on research and on-farm verification. They are generally the most economical rates, even for high yield situations.
• Consider replicated strip trials to determine the effect of lower or higher rates on yield. Fine-tuning fertilizer use needs to be an on-going process.
• Comparison shop. Look at different products and do your “fertilizer arithmetic” to compare the actual cost per pound of nutrients.
• Work with a reputable dealer who can provide quality product, price assurances, timely delivery, and well-maintained equipment. Remember, service after the sale is also important.

Check out a good story by Farm Industry News that offers the latest look at RTK signal correction across the Midwest.

The umbrella of real-time kinematic (RTK) correction signals that covers much of the Corn Belt will be larger and more robust by the time the 2011 planting season rolls around. As a result, growers in many geographies will have multiple correction signal options for driving RTK navigation systems.

Going into 2010, most of the heart of the Corn Belt was covered by either radio or cellular systems, or both. But there were coverage gaps. By 2011, a coverage gap in Illinois will have been plugged, and coverage in Ohio, Indiana, South Dakota, Nebraska, Kansas, Missouri and other states will have been beefed up.

The improved coverage is a result of build-outs of both traditional radio-based systems and newer cellular delivery systems, which distribute RTK corrections via the Internet through cellular communications networks. Unlike in recent years, when additions to the cellular delivery system were dominated by new and expanding state department of transportation (DOT) systems, this season’s new cellular entries are systems dedicated to agricultural users.

You know how sometimes things happen in farm fields that are either out of your control, or perhaps something known as operator error. Well, some of those oops provide valuable learning experiences, don’t they?!

Such was the case with central Nebraska farmer Kurt Kroeger. Now Kroeger is a fairly advanced precision ag aficionado, playing with many things on his 1,250 acres. He’s a big fan of Ag Leader because the tools work well with all colors of equipment that he owns. And he’s become a whiz at SMS Advanced software to write his own variable-rate (VR) seeding and fertility prescription maps.

Another technology that has intrigued him since the late 1990s is the nitrogen crop sensor. “I followed the GreenSeeker sensor since it came out. Then I watched the Holland sensor become Ag Leader’s OptRx technology—and became one of the first to buy them.”

So, this past spring he mapped out a good test in a couple fields under pivots. “In one section of the corn field I applied a high rate (44 lbs./acre) of 32 percent nitrogen plus thiazole as a high yield check. In the second section I applied 32 percent based on the OptRx sensor, and in the third section I applied the nitrogen according to my fertilizer supplier’s best VR map based on soil type and fertility,” Kroeger says.

Then, that unplanned ‘fluke test’ happened, as he calls it. “The coolest thing in the world happened. When the corn was a foot tall, my mini-corner pivot got stuck all night and watered one spot heavily. As you can imagine, in another couple weeks when I applied the fertilizer, I had a nice and visible section shaped like a Nike swoosh mark in the field where all the nitrogen had leached away,” he says.

The OptRx sensors recognized the deficient plants in his ‘swoosh’ area and applied 50 to 56 gal., which was quite a bit higher than the whole field average of 34 gal. And compared to the 36 gal. on the retailer VR section, the OptRx not only saved 2 gal. it produced more yield too. These results not only sold Kroeger on the OptRx technology, but it changed his whole point of view on fertility in his sandier soils.

“The OptRx produced more uniform and higher yields, based on a philosophy of feeding all plants that need more fertility, which is different then the soil map VR philosophy that feeds the good areas and starves the poor areas of a field. It makes the whole field more uniform. I want every acre to pay for itself.”

Needless to say, Kroeger is sold on using the OptRx on all his corn next year. “If I had achieved the same results across my whole farm as I did in the plots, the system would have paid for itself this year alone,” he adds.

His next learning challenge…figuring out a way to use it on his sprayer to apply N using drop nozzles.
