The AI3070 was designed specifically for fungicide application in cereal crops making it ideal for controlling fungal diseases. The prevalence of fusarium in wheat and other cereal crops makes this an ideal nozzle for small grain producers. The AI3070 is designed to maximize the efficacy of a grower’s fungicide application which contributes to higher yields and a higher quality grain sample.

The AI3070 is offered in six VisiFlo® color-coded sizes from -015 to -05 capacities. It is constructed of acetal (polymer) with a recommended operating range of 20-90 psi. The AI3070 tips are easily installed on Quick TeeJet® nozzle bodies. The tips are currently available at local TeeJet Authorized Distributors.

Dr. Wolf says the program focuses on research and education of applicators to “maximize control of weeds and minimize spray drift.”

One of the educational tools he uses is a spray table that is designed to allow applicators to actually see the differences between spray nozzles, the droplet size and drift produced. “I encourage them to put water in their sprayer on a day when they’re not busy, turn the sprayer on, get out and walk along and do some comparisons,” he said.

On Target Application Academies will be held throughout 2012 at industry and state events. Sessions will be about two hours long and cover a number of topics including best practices for self applications, nozzle selection, adjuvants, calibration, sprayer set up, equipment clean out, and more. More information on dates and locations will be available from BASF representatives and on the BASF website.

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.

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.

Scouting remains an important factor to help insure that a grower is making the most informed decisions possible, says Fulton. “Whether it’s you the grower or a consultant, getting out in the field and collecting additional information is important in making better decisions,” he says.

Tools and technology are available that can help in cost savings, he adds. “Producers need to reduce input costs but also to maximize yields and profits at the end of the year. These are the types of inputs where precision ag technologies can have an impact. Growers are spending a lot of money producing a crop, and the amount increases each year,” he says.

Data collected from trials conducted over the years illustrate the savings that are possible from using precision agriculture technologies, says Fulton. A guidance system alone has been shown to save up to about 12 percent on average, he says.

“You can get a larger savings, and some people don’t do quite that well. Much of it is dependent on the operator and what you were using previously. But 12 percent is a big addition when you look at what you’ll invest to get into guidance,” says Fulton.

The Field-IQ system pairs seamlessly with the guidance capabilities of the Trimble FmX integrated display or CFX 750 touch screen display, which both run Trimble’s unique overlap detection technology. Farmers using the Field-IQ crop input control system for seed placement have reported average savings of 5-10 percent from reduced seed input costs and less waste.

Trimble’s Field-IQ system is compatible with a wide variety of crop and application equipment, providing monitoring for planters, air seeders for small grains, or granular strip till systems. Seed monitoring on row crop planting systems allows operators to obtain information related to how their seeding system is performing. This includes factors such as singulation, skips and multiples, and quality of spacing for an entire planter average or detail by individual row. For fertilizer, variable rate application capabilities can be driven by a prescription map or real-time with Trimble GreenSeeker sensors.

The Field-IQ system is easy to install on application equipment from a broad range of manufacturers, allowing farmers and custom applicators to use and enhance the performance capabilities of their existing equipment without having to start from scratch.

“The new Field-IQ enhancements optimize planter operation by delivering more accurate seed placement, giving the operators more confidence in their planting applications,” said Erik Arvesen, vice president and general manager of Trimble’s Agriculture Division. “With the addition of rate and application control for up to six different materials, the system now manages functions that span the entire growing season.”

The new seeding and multi-rate capabilities for the Field-IQ system are expected to be available in March 2011. Contact a local Trimble dealer at www.trimble.com/locator for more information.

As the grand prize winner in the competition at the AFBF 92nd annual meeting, McDowell won one full year’s use (or 300 operating hours) of a New Holland tractor. New Holland has provided a year’s free use of a tractor to the grand prize winner for 21 of the 22 years the program has been conducted.

Other top awards of $500 apiece included Rory Frick of Illinois who developed both the “most innovative” and “most widely useable” concept. Frick’s multi-functional ladder contains platform steps that remain parallel to the surface at any inclination. When unfolded at a 45-degree pitch, the ladder resembles a staircase. When in the storage position, folded and locked, the ladder is only 2 inches thick and can be used as a ramp. Wheels can be added to convert the ladder to a creeper (mechanic’s tool) and push bars can be added to make a utility cart. It provides safe, easy accessibility to even the physically challenged and reduces the risk of injury.

The “most cost-effective” idea came from Merle Langeland of Michigan. Langeland’s Care Chute with Quick-Attach Skid Steer Bracket is a calf-sized, portable animal care chute that is easy to set up, clean, move and store. It is the ideal size for working with calves.

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.

The Alabama Precision Agriculture Team discovered that some users of GPS/GNSS-based technologies were not optimizing the GPS/GNSS correction services for their particular field operations (e.g. using the WAAS correction service for planting). It is imperative to understand the different accuracies associated with GPS/GNSS correction services so one can maximize benefits of their precision ag technologies.

GPS/GNSS Drift
Upon returning to the field, a producer may notice discrepancy between what he/she knows to be the crop row where an AB line was previously established, and where the guidance device is suggesting the AB line is located. WAAS and sub-meter correction services may seem accurate during one field operation but be off-track when the operator returns to the field. This result is because there is typically large ambiguity between pass-to-pass accuracy and year-to-year accuracy or GPS drift.

 GPS/GNSS Drift / Year-To-Year Accuracy (Y2Y) / Long-term Accuracy: Drift can be defined as GPS/GNSS receiver (guidance system) accuracy over time. Causes of drift are changes in satellite configuration, operating near trees or other obstacles, and satellite data errors.

 Pass-to-Pass Accuracy (P2P): Represents the short-term (<15 min.) relative accuracy of a GPS/GNSS receiver but does not necessarily reflect long-term accuracy (which includes drift). One can think of this as the accuracy between adjacent, parallel passes made within 15 minutes of one another.

Since manufacturers typically report pass-to-pass accuracy, it is generally used for equipment purchasing decisions. However, this accuracy may not reveal how the guidance or GPS/GNSS-based system will perform relative to the last operation or over the course of time if previously established AB lines are re-used. This result is especially true when AB lines are established for planting and re-used for harvesting.

As mentioned above, GPS/GNSS drift is largely due to the changing GPS/GNSS satellite constellation patterns used by the guidance device to derive positional information. GPS/GNSS satellites are in continuous motion orbiting the earth twice per day in a repeated pattern. It is assumed that the GPS/GNSS satellite constellation and environmental conditions will not drastically change within a given 15 minute time span, thus derived positions using the same satellite constellation and environmental conditions will be closely correlated relative to each other. However, the GPS/GNSS satellite constellation and atmospheric conditions change over just short time periods resulting in different satellites in varying geometric configurations. Therefore, the magnitude of drift expressed by your device is dependent on the correction service used. Using WAAS, potential range of drift is plus or minus 4.7 feet. With sub-meter accuracy, it’s 2.3 ft.; with decimeter it’s 1.7 ft.; and with RTK it’s 1 inch.

There are great opportunities for this technology in cotton production for varying the application of plant growth regulators, harvest aids, and nitrogen. However, the users must understand the limitations of their equipment and the sensors being used in order to maximize the benefits.

Users should understand the agronomy behind prescriptions and be comfortable with the recommendations. Familiarity with these prescriptions can allow users to fine tune them for their environment or to develop their own prescription algorithms. They should also understand their equipment and know how to tune their controller for optimum response. As with all new technologies, users should seek advice from experts and those who are already implementing sensor–based variable rate application.

“We talk to each producer that we work with, and they are the ones telling us that they sure use less chemicals on a field than they used to because of the (precision farming) technology they have,” he said. “I think from those discussions, most are figuring they are saving between 5 to 10 percent on a field with GPS technology.”

Metzger likes to mention the story of a farmer who has been enrolled in the Farm Business Management Program for several years. When ordering herbicide for his total crop acreage he always added five percent to what he had figured and ended up using the entire amount each year. However, the year he added a sprayer with GPS and boom control to his operation he took the entire extra five percent that he always ordered back to the chemical dealer because he didn’t need it.

With the average chemical cost for wheat today at $31.23 per acre, Metzger said there is the potential for great savings.

“If you start looking at saving $2 to $3 an acre on chemical on a couple thousand acres of wheat, it doesn’t take very long before the savings can add up to $5-, $10- or $20,000 on an average farm,” he said.

“And as the costs increase, there is even more of a desire to save all the time,” he continued. “If we didn’t have the GPS units we might still be over-applying by going around sloughs twice, doing the headlands twice – those types of things. But with the GPS and the automatic shutoff, those areas of over-application are taken care of.”

And the savings doesn’t end with chemicals. The five major costs associated with crop production–chemicals, fuel, repairs, seed and fertilizer–can all be trimmed back. Read on for more details.

I spoke the other day with Jeff Bentley, Ag Leader Technology’s sales manager for GPS Guidance and Steering, to get his take on the usefulness of non-human steering in the fall.

He told me there are three major areas that auto steer technology can benefit a farmer in the fall—combining, field tillage and fall fertilization. And you don’t necessarily need the higher cost RTK differential correction signal.

OnTrac

“In the combine, either our OnTrac2 assisted steering system or our advanced ParaDyme automated steering will benefit anyone with a platform head to keep it completely full of soybeans or wheat during harvest,” Bentley says. “We have some customers who also use RTK to guide a corn head down rows that were planted using RTK auto steer.”

ParaDyme

When it comes to fall tillage, many growers have done some on-farm testing with automated steering. “The results growers tend to see when comparing manual steering to auto steering usually range from three percent up to 10 percent greater efficiency. And you can use a wide range of signals, from the free WAAS signal to OmniSTAR to RTK.”

The third fall application that benefits from auto steer is fertilization. “Growers use it when applying anhydrous, when using a spinner-spreader and especially when applying fertilizer as part of a strip-till operation, using RTK so they can come back and plant exactly over the top next spring,” Bentley says.

To control these systems, Bentley says the OnTrac2 uses the EDGE display. For the ParaDyme, you can use either the EDGE or the INTEGRA display. “And with either display you can add DirectCommand for section control and rate control for anhydrous bars and strip-till air carts.”

Bentley says if you haven’t invested in steering technology yet, its year-around uses will deliver greater efficiency, fuel savings, input savings, time savings and especially less operator fatigue.

Just in time to begin soil sampling in preparation for the 2011 growing season, FieldRx is bringing crop consultants and agricultural dealers a more user-friendly program for writing custom fertilizer prescriptions. Designed by ag professionals for ag professionals, FieldRx was created to eliminate the frustrations with existing precision ag software programs while providing concise grower reports and smaller controller files.

“We’re really excited about bringing FieldRx to market because of the solutions and time-savings it’s going to bring to crop consultants and dealers,” said David Krueger of Ag Software Designs. “FieldRx will streamline the process for using VRT data and making custom recommendations to growers.

A highlight of the FieldRx engine is the ease of uploading field borders and sample points. In addition, lab results can be imported directly into FieldRx from some labs without the user having to manually obtain and upload the data.

“Our goal in developing FieldRx was to put users first by saving them time and eliminating the potential for human error that can arise from manual data input,” said Lance Ramthun of Ag Software Designs. “A lot of VRT programs currently on the market are extremely time-consuming to set up, and one wrong click while inputting data can be very costly for dealers.”

FieldRx boasts a minimal learning curve for users, who only need access to the web to get started. Furthermore, users don’t need a high-level of computer proficiency to operate the program.

“We know software and new technologies can be very intimidating to users, especially if there is a lot of potential for error,” said David Hydrick of Ag Software Designs. “People are going to be extremely satisfied with how easy FieldRx is to use.”

In addition to soil test recommendations, the FieldRx engine has the power to support many other variables for prescription writing in future releases. Other capabilities include web services that are available for other vendor’s software tools to upload data directly to FieldRx.

I checked in with Ag Leader’s Chad Huedepohl yesterday, and he reminded me of the many benefits of controlling these product applications with their DirectCommand system linked with either the INTEGRA or EDGE displays.

“Whether growers are applying granular fertilizer with a spinner spreader, liquid fertilizer, anhydrous ammonia, or a combination on a strip-till toolbar, DirectCommand can control variable-rate application for each product,” he says.

Huedepohl, sales manager for DirectCommand, says growers are cutting application costs by 5 to 15 percent due to reduced overlap with AutoSwath control. “It can control up to ten sections on a boom, or even control spinner spreaders. Growers can also inject N-Serve into anhydrous or Instinct nitrogen stabilizer into a manure application,” he adds.

Use the INTEGRA display to control, adjust and record up to 5 different products in one application, or the EDGE display to handle two products. Both displays offer easy-to-use controls with on-screen guidance showing actual map coverage, and it’ll monitor up to three outside-the-cab pressure gauges.

With the INTEGRA display, all application details are captured on a Smart Report to easily generate PDF files that can be used as government certified application maps. And all data is easily transferred into SMS software for analysis and future year input needs and budgets.

When the built-in, dual-frequency receiver is upgraded to GLONASS, it provides the option to nearly double the number of available satellites from which to receive satellite signals.

For precision planting operations, the CFX-750 display is compatible with Trimble’s Field-IQ crop input control system and Tru Count clutches and can perform section control on up to 48 sections. Add rate control with the Field-IQ system to save costs and increase yields while also keeping records of what was applied. Additionally, operators can increase visibility from the cab by using the two live video feeds on the CFX-750 display to view the implement being pulled behind the vehicle.

“The Trimble CFX-750 display features the industry-leading Trimble Maxwell 6 chip that tracks up to 44 satellites simultaneously including GLONASS,” said Erik Arvesen, vice president and general manager for Trimble’s Agriculture Division. “This is a great high-performance, entry-level platform that can be upgraded to the Field-IQ section and rate control system as the farmer’s needs grow.”

The CFX-750 display is affordably priced starting at US$2,995 MSRP and is expected to be available in September 2010. Contact a local Trimble dealer at www.trimble.com/locator for more information.

I spoke the other day with Iowa farmer Tim Palmer, who also is president of the Conservation Districts of Iowa—a group of 500 county commissioners who are responsible for carrying out state laws and programs within district boundaries. Palmer had just returned from their annual conference where the theme was ‘Mastering Conservation 101.’

“Our whole conference was all about topics focused on improving water quality. If we can keep soil in place, water quality automatically improves,” he says. “We discussed many ways to help educate growers on conservation methods; about how there’s more to soil quality than organic matter and yield. And we offered breakout sessions on planter adjustments, managing no-till residue, precision farming, value of no-till, livestock grazing management and other topics.”

Chad Huedepohl, DirectCommand sales manager for Ag Leader Technology, spoke to the group about how precision farming tools can help promote conservation practices. He addressed three areas during his talk:

1. Auto guidance: “I talked about the myth that auto steer only works in fields with straight rows. Our SmartPath technology tracks the contours in a field as you drive the first path, then it takes over the steering during subsequent paths—which helps growers farm fields differently to keep erosion in check. And auto guidance eliminates row marker trenches that can turn into highly erodible gullies during heavy rain events,” Huedepohl says.

2. Efficient nitrogen application: “Our OptRx crop sensor system can help growers reduce excessive nitrogen application by reading the crop and applying only the amount needed, instead of applying a flat rate of nitrogen across whole fields.”

3. Reduced chemical and seed over-application: “As growers adopt more contour planting to reduce soil and water movement and erosion in square fields, they create more point rows which can lead to over-application of seed and chemicals,” he says. “With auto guidance and row/boom shutoff, that problem is eliminated. Our AutoSwath technology combined with planter row shutoff devices not only provide less corn lodging and herbicide over-application, it saves on seed and chemical input costs, too.”

As one of Raven’s largest OEM customers, Equipment Technologies can factory install the following precision options on any Apache model: SmarTrax auto-steering, the SCS 5000 application rate controller, the EnvizioPro or ViperPro field computer and the AutoBoom and AccuBoom boom controls.

The Apache sprayer has earned a reputation for its affordability, reliability and ruggedness. Now, the AS720, AS1020 and AS1220 models incorporate engineering and design refinements that make them more affordable, more reliable and more rugged than ever before. National Sales Manager, Paul Nielsen explains, “The 2011 model year represents the culmination of years of customer feedback and planning.” Nielsen adds, “It is truly rewarding to see all these changes come together without compromising what makes the Apache special and that is the promise of efficiency and R.O.I. – doing more with less. Our customer, the farmer who considers himself a business man, appreciates that and we are proud to be able to deliver on our promise of the best value in the industry in such a big way.”

Specific design enhancements for all three 2011 Apache models include:

All-new cab:
4-point mounted cab. The cab is now fulcrum-mounted at four points. Combined with a wider stance, this reduces the g-forces felt by the operator by 37.5% which makes for the Apache’s most comfortable ride yet.

Improved visibility and larger floor plate. The all-new, custom cab boasts a 12% increase in overall floor space. With the wrap-around glass, the operator is given an improved view of the front wheels as well as a better view of the booms.

Noise reduction. Noise sources such as the engine and exhaust have been moved farther from the operator resulting in a 9% reduction of in-cab noise.

Cab entry. The new Apaches feature a rear-hinged door and larger catwalk to maneuver in- and out of the cab.

Seat and “buddy-seat.” With the increase in floor space, the new Apaches provide a “buddy-seat” for safer learning and instruction.

HVAC and electronics. HVAC adjustments have been placed in the steering column and the electronics are CAN-ready.

Chassis, product tank and options:

Axle widths. Applicators can now choose between a 120″ fixed axle or an adjustable axle that allows widths between 120″ and 160.” These new adjustable configurations provide increased options for an array of row spacings and a wider stance for increased stability.

Lighting. The 2011 Apaches feature better illumination in- and outside the cab with a 22% increase in the number of bulbs compared to last year’s base lighting package. All exterior lights except the hood lights are adjustable and are dual-beam Hella bulbs.

Custom, UV product tank. A custom, roto-mold tank has been introduced for the 2011 model year. It is contoured to the chassis and no longer utilizes a tank skid. This allows the tank to be lowered and contributes to better visibility of the booms, a lower center of gravity and a better ride.

Fill station. The new and improved fill station features a more intuitive layout and an LED lighting system so operators can quickly, accurately and safely get busy spraying at all times of the day and night.

Larger rinse tank. The Apache now comes with a 100-gal rinse tank.

Power train improvements for the AS1020 and AS1220:

While the AS720 with 42″ crop clearance can still be purchased with an ITL/JCB transmission, it is the introduction of the ZF transmission on the AS1020 and AS1220 models that pushes the efficiency of the Apache’s legendary mechanical drive to new levels. The AS1020 and AS1220′s ZF transmissions feature a lock-up torque converter that allows for as much as a 26% increase in the ratio of power supplied to power used compared to the 2010 model year. The result is more power to the ground than ever before which gives the operator increased traction in a variety of ground conditions. Another benefit of the Apache’s re-engineered drive train is an increase in fuel economy of an estimated 9.3% on the AS1020 and 17.4% on the AS1220 at optimum spraying speeds of 12 to 16 miles per hour.

Equipment Technologies is the largest independently-owned manufacturer of self-propelled sprayers in North America. Operating from its 108,000 square foot headquarters in Mooresville, Ind., the company distributes its sprayers throughout North America, Ukraine and Australia through a network of independent dealers.

To this end, the Center for Integrated Pest Management (CIPM) announced the launch of a new Pesticide Environmental Stewardship (PES) website. The site (http://pesticidestewardship.org) is designed for anyone who applies, sells, stores, or disposes of pesticides; provides advice or training on pesticide use; or is involved in pesticide stewardship or regulation.

“Our ultimate goal is to cover the basic tenets that apply regardless of who you are, where you live or the pest you’re trying to control,” says Wayne Buhler of North Carolina State University, PES national coordinator and a Pesticide Safety Education Program coordinator for North Carolina. “There are fundamental principles and practices to be aware of whether you are protecting agricultural crops, homegrown vegetables, a lawn or golf course. We hope that whenever the choice is made to use a pesticide, good stewardship practices will be followed.”

The new website complements the work of county extension agents and state-level Pesticide Safety Education programs. It covers a wide variety of stewardship topics, ranging from pesticide storage, handling and disposal…to how to avoid drift, runoff and leaching during and after the application. Homeowners can go straight to a section geared to their needs.

Buhler’s colleagues in the Pesticide Safety Education Program from across the United States were instrumental in the development of PES, including Ron Gardner of Cornell University, Carol Ramsay of Washington State University, Jim Wilson of South Dakota State University and Fred Whitford of Purdue University. Other scientists in academia, extension, government and industry (http://pesticidestewardship.org/Pages/About.aspx) partnered with CIPM on the project, including members of the Weed Science Society of America, the Entomological Society of America and the American Phytopathological Society.

“We know there is a wealth of expertise in the public and private sector regarding pesticide stewardship,” observes Ron Gardner. “We look forward to a growing list of partners who will help us add value to current and future topics on the site.”

A pesticide resistance management topic is currently under development. Future plans include educational quizzes to reinforce important stewardship concepts and self-assessment tools to evaluate personal stewardship practices.

“Search the web for phrases like ‘pesticide stewardship and drift’ and you will get thousands of results,” says Carol Somody, senior stewardship manager for Syngenta Crop Protection and PES industry coordinator. “It can be quite overwhelming to someone who wants to start with the basics, and teaching the basics is the purpose of PES. It provides a much-needed entry point to essential pesticide stewardship information.”

10 Stewardship Tips from the Pesticide Environmental Stewardship (PES) Website

1. Read the label before buying the pesticide.

2. Buy only the amount of pesticide needed for one season.

3. As a general rule of thumb, the temperature inside the storage area should not get below 40 F or over 100 F.

4. Calibrate equipment carefully to assure that the pesticide is applied at labeled rates.

5. Be aware of the current and probable future weather conditions in order to make the best application decisions to prevent drift.

6. Locate the mixing/loading site away from wells, streams and lakes.

7. Never leave a tank while it is being filled and pay constant attention during filling to prevent overfilling and spilling of the pesticide on the ground.

8. When you empty a container, allow it to drain into the spray tank for 10 seconds after it begins to drip.

9. Remember that exceeding the label rate of application is a violation of the law!

10. Follow the label each time you mix and use the pesticide, and follow the label when storing or disposing of the pesticide. Do not trust your memory.

This was just one precision farming economic message presented by Matt Darr, Iowa State University ag engineer, during a field day at its Northern Research Farm field day, according to a story in AgriNews.

“This is suitable for non-critical guidance, including tillage, spraying and seeding/drilling,” Darr said. “They are also used for autoswath systems on sprayers, but accuracy will decline in larger fields.”

Investing in a $2,000 light bar for a sprayer can cut chemical costs by 4 to 8 percent per year, Darr said. In areas with rugged terrain, the savings have been as much as 17 percent.

Dual frequency correction offers advances over single frequency correction and provides pass-to-pass accuracy within 4-inches or better, Darr said. This works well for precise auto steering for planting and for planter section control. It requires a yearly subscription that can range from $800 to $1,500.

Real Time Kenematic, or RTK, correction is the most accurate GPS correction because it uses a privately-owned reference station located close to the GPS receiver. RTK can provide one-inch pass-to-pass accuracy and is the only GPS correction that provides year-to-year position stability. RTK allows controlled traffic, strip tillage/fertilization/planting and extremely precise autosteering. Darr said that although RTK receiver costs have come down, the investment is still high from a cost and complexity standpoint.

RTK networks maintained by groups of implement dealers are available for a subscription fee. The cost is similar to a dual frequency subscription.

• Strip till and RTK guidance saves a huge amount of hours and fuel savings, while delivering big conservation and environmental benefits.
• Planter clutches can save 3-7% in seed costs.
• Banding P&K can reduce rates as much as 40%.
• Spray boom section control can save 5-15% in input costs.

“When I used to shut the boom off, the nozzles didn’t shut off immediately,” French said, who custom sprays about 50,000 acres of rice and soybeans in northeast Arkansas. “There was still product coming out of the tips, and that’s just wasting money.”

To overcome the frustrating problem of continued spraying after the boom has been switched off, French started using TeeJet Technologies’ Flow Back valves.

“The shut off time when the nozzles actually quit spraying went from 5 to 8 seconds to about 1 second when we started using the Flow Back valves,” he said. “This reduces chemical waste tremendously and saves our customers a lot of cost. There is no doubt it saves chemical.”

Sprayers with standard valves trap pressure in the boom when they are switched off. As a result, the boom continues spraying for several seconds before completely shutting off. The technology behind Flow Back valves includes an extra passage that allows boom pressure to be dissipated immediately – this passage allows spray solution to return to the tank to relieve that pressure, and is the key to fast shut off at the boom.  The boom remains full of liquid and spraying resumes immediately when the valves are switched back on.

“Due to the rapid shut off of spray tips when the boom sections are shut off, Flow Back valves eliminate product waste and improve sprayer accuracy by reducing skips, overlaps and re-sprays,” said Pat Maney, wet products business manager with TeeJet Technologies. “Applicators can spray to the end of the row while minimizing the overlap that can occur in the end rows.” Without Flow Back valves, operators must try to compensate for shut off delays of five to 10 seconds or more, which can lead to over application or costly re-sprays.

Flow Back valves are compatible with all levels of sprayer control systems, from simple to sophisticated, and require no special wiring or plumbing. They also are an excellent companion to automatic boom section control systems. The compact, electrically-actuated Flow Back valves are available in three product platforms – 430 FB, 450 FB and 460 FB ‑ each rated for different pressures and flows.

Called SmartPath, this new ‘drive and guide’ pattern is designed for fields beyond the straight and flat, and it doesn’t require the traditional set-up using beginning and end points.

“If you have farmed contoured fields, you know there is no sequential pattern that is followed; it’s much more random. With SmartPath, once you drive the first pass, all subsequent passes are GPS-guided to follow the previous path,” says Matt Leinen, product manager with Ag Leader. “This pattern will make planter row shutoff or sprayer boom shutoff technology very effective, especially when dealing with the convergence of many point rows.”

While this type of pattern isn’t unique in the industry, Leinen says their technology is designed to follow the best path. “The challenge with this type of pattern is the convergence of numerous paths which come together that are unevenly spaced. We designed the SmartPath to select the right path.”

This pattern is available with any of Ag Leader’s manual guidance, assisted steering or automated steering products, including the INTEGRA and EDGE displays, as well as the OnTrac2 and ParaDyme steering systems.

SmartPath is joining a family of guidance patterns available with Ag Leader’s guidance and steering, including Straight AB, A+, Identical Curve, Adaptive Curve and Pivot. It is available in the following firmware releases: Version 1.5 of the INTEGRA display and Version 3.5 of the EDGE display.

I spoke with Cory De Jong, Certified Crop Advisor and GIS/Agronomy Sales at Sully Cooperative Exchange in Sully, Ia. today. They tested the Ag Leader OptRx crop sensor system last year during all the heavy rains. “We strictly used the sensors on a sprayer for mapping purposes, as we weren’t set up yet to apply nitrogen. And we saw a lot of (plant health) variability in fields, covering several thousand acres that we mapped,” he says.

“Last year, sidedressing N definitely paid due to all the spring rain we had here in central Iowa. On average, growers gained at least 15 bushels an acre by sidedressing. And if they applied variable-rate, they could have gained 30 bushels,” De Jong says. “We saw 50 bushel per acre differences within fields with the OptRx. So this year we’ve got a bar ready to custom apply with OptRx to apply sidedress N. And we have a bar with OptRx that customers can rent, too.”

De Jong says there is a lot of hog and chicken manure used by customers in his territory, and they are interested in this sensor technology. “For example, one grower who has a lot of hog buildings wanted to know how much N he was getting from his manure. We used the sensors to shoot the plant leaves and saved him input dollars. And in some areas the N gets reallocated to areas of the field where N is needed most,” he adds.

He feels this sensor technology will gain more and more users, once growers see the benefits of variable-rate application. “As interest picks up, we’ll add sensors to a sprayer that will just be dedicated to sidedressing. We may be losing some N business due to manure, but we’re gaining business by helping customers apply N only where the sensors detect it is needed—as well as how much the plants need.”

“In the last year or two, we’ve seen large increases in first-time buyers of precision agriculture technology. These have included livestock producers, forage producers and row-crop producers.

“The increasing cost of inputs has caused everyone to think about how they can save money, and precision agriculture figures into that.”

The benefits of using guidance systems are numerous, she says.

“It decreases skips and overlaps — that’s one of the biggest advantages. It also minimizes driver error and eliminates guess rows. In row crop situations, we’ve seen up to an 8.5 percent decrease in overlapping. In a pasture situation, we would expect that to be much higher because you obviously would have no rows to go by.”

A guidance system increases efficiency, allowing the grower to operate at faster field speeds. “You can cover more area with fewer hours of operation, and you’re able to reduce per-acre fuel consumption because you reduce overlaps in the field,” says Winstead.

Owners of granular spinner-spreader fertilizer rigs and anyone with a sprayer will benefit thanks to new dual product control. “Fertilizer applicators can now variable-rate apply both P and K, or apply a fertilizer blend along with micronutrients at the same time,” says John Howard, DirectCommand Product Manager with Ag Leader Technology. “The EDGE has the ability to precisely control the speed of the spinners to deliver spread pattern accuracy.”

For sprayers, dual control means you can control both a liquid carrier and a direct-injection pump. “With our DirectCommand system’s AutoSwath control, and the interface to the Raven Sidekick chemical injection pump, growers and retailers gain complete control of both products,” he says.

Howard says that fertilizer retailers who seek an economical monitor with just the right functionality for their needs will be pleased with this new addition to the EDGE display—especially with the auto steering guidance control features added last December. “We continually strive to provide practical and economical solutions, while helping users upgrade as seamlessly as possible.”

Current EGDE display owners can download this firmware upgrade to their monitor. http://www.agleader.com/customer-support/downloads/

Difference between EDGE and INTEGRA monitors:
http://www.agleader.com/products/displays/

Chemical Injection
Dual product control in the EDGE display will support sprayer control of a liquid carrier and a single injection pump. Like other Ag Leader products, the EDGE display’s DirectCommand system now interfaces to the Raven Sidekick chemical injection pump for complete control over chemical injection applications. The EDGE display and CAN module will replace the Sidekick Console, directly connecting to the injection pump. Automated prime and calibration routines as well as advanced sensor diagnostics are part of the new functionality. This addition can be used for herbicide, fungicide, and insecticide as well as nitrogen stabilizer injection application.

Granular Fertilizer Application
Dual product control also means two channels of granular product control in the EDGE display. Operators have the ability to apply two products simultaneously at varying rates, either manually or using a prescription. The most common applications of this feature will be in spinner spreader and strip-till operations.

“We continually strive to provide practical solutions to enhance user-experience and productivity,” says John Howard, Product Manager for Ag Leader. “The addition of dual product application control combined with existing EDGE display functionality provides an economical solution with the tools to achieve this.”

Additional functionality of the EDGE display includes SeedCommand, DirectCommand, yield monitoring, guidance and steering capabilities. In addition, the EDGE display is plug compatible with Ag Leader’s INTEGRA and InSight displays; this gives users who wish to upgrade in the future a seamless transition.

“These low-drift nozzles are really having a revolutionary impact,” says Dr. Tom Wolf, a research scientist with Agriculture and Agri-Food Canada and a member of the Weed Science Society of America (WSSA). “Research shows we can reduce the spray that drifts away from its target to less than 0.5 percent of the applied amount. That’s a decrease of more than 80 percent compared to conventional sprays.”

The secret is a clever design that reduces the internal operating pressure of the sprayer nozzle and mixes air into the herbicide spray as it is applied.

“We’ve seen nearly 100 percent adoption among custom applicators in Canada, and up to 50 percent of the more innovative growers on large farms are using them as well,” Wolf says. “They have clearly found the devices work well in their operations.”

Still, there are obstacles to even broader adoption. Not all weeds and all herbicides respond the same way when changes are made to reduce the number of very fine spray droplets.

“It can be tough to provide practical recommendations to applicators on diversified farms,” Wolf says. “But scientists are meeting that challenge by communicating their research findings to herbicide manufacturers and applicators alike. We’re finding low-drift sprays can be used successfully in the majority of situations an applicator is likely to encounter.”

Robert Klein, a WSSA member and crop specialist at Nebraska’s West Central Research and Extension Center, recommends combining multiple drift control strategies in order to achieve optimal results. Here are eight proven techniques he recommends:

INCREASE SPRAY COARSENESS. Switching to low-drift nozzles has a large impact on drift. For traditional nozzles, lowering pressure can also increase droplet size and reduce drift. There is a fine line, however, between droplets that are too small (causing excessive drift) and too large (providing insufficient coverage). Look to your nozzle manufacturer for guidance on the recommended pressure. Low-drift nozzles typically require a higher pressure to operate properly.

GAUGE THE WEATHER. Environmental factors can be critical to the control of spray drift. Klein cites wind speed as one important example. “When wind speed increases, so does the potential for drift downwind of the sprayer,” he says. Today’s ultrasonic weather sensors can help. A far cry from yesterday’s rudimentary weather vanes, sensors measure air temperature, humidity, dew point, barometric pressure, wind chill, wind direction and wind speed. The units are extremely compact and can be mounted inside a sprayer cab. That means the applicator has continuous, up-to-date weather data and can apply herbicides when they are least likely to drift.

CONTROL THE FLOW. Modulated flow controls reduce drift by rapidly pulsing each spray nozzle on and off. This allows pressure and droplet size to remain constant as the sprayer moves across the field at various speeds.

REV UP THE AIR SPEED. Air-assisted sprayers emit a high-velocity, downward air stream that pushes the spray droplets directly onto the targeted weeds or treatment area. As a result, they can reduce drift if used properly.

CREATE A BUFFER. Untreated zones around fields can serve as buffers that keep drift away from off-target sites.

ADD DRIFT RETARDANTS. If you use a traditional sprayer, special additives can be used to reduce the number of fine droplets. Make certain, though, that you select an additive especially designed for the type of nozzle and herbicide you use. Certain additives can be a minus when used with the wrong nozzle tip.

HOOD YOUR SPRAYER. By mounting hoods around the nozzles on a sprayer boom, you can create a physical barrier that reduces spray drift. It’s a simple but effective technique.

MONITOR THE BOOM HEIGHT. Extension specialists recommend keeping booms close to your weed target in order to decrease the possibility of downwind drift. But be careful to follow the manufacturer’s instructions so you maintain the uniform spray pattern and coverage needed to control weeds effectively.

“Each of these approaches has its strong points,” Klein says. “In order to make sure we’re using the optimal combination of techniques for each scenario, it is important for scientists, applicators, farmers and manufacturers to communicate closely and share best practices. That’s one of the strengths of WSSA. The organization brings everyone together to share research and explore the best science-based approaches for managing drift.”
