Precision Pays

A grower sustainability panel took place during the recent Bayer CropScience 2012 Ag Issues Forum with the theme of “Hands in the Dirt: First-Hand Grower Experiences.”

Panel member Nancy Kavazanjian, a farmer from Wisconsin who grows corn, soybeans and wheat, talked about what the word “sustainability” meant to her. “When a farmer hears the word sustainable they kind of cringe,” she says. “It concerns them that they’re being forced to do something that they’re not already doing.” But she adds that most farmers are being sustainable since they are multi-generations on the farm and they have to be sustainable for that to happen. To become more sustainable Nancy says they use cover crops and precision ag to make sure they can strip-till and they definitely use new technology and that includes seed technology to get the best yields. The use of these technologies reduces the amount of inputs they have to use.

Idaho is synonymous with potatoes, but there is more corn in the ground there these days to support a growing dairy industry.

USDA Agricultural Research Service (ARS) scientists have found that some Pacific Northwest farmers can increase corn yields by using strip tillage and banding fertilizer instead of conventional tilling. Strip tillage and banding involves excavating a single row for planting about 6 to 12 inches wide and 6 to 8 inches deep with a knife-like shank that can also inject fertilizer directly below the seed.

The scientists found that using these practices increased corn grain yields on severely eroded soils st higher elevations by 12 percent the first year and 26 percent the second year. This translated into yield increases between 11 and 26 bushels per acre.

One of the stops on the 2011 CTIC Conservation In Action Tour in Ohio last week was the farm of Todd Hesterman in Napoleon, Ohio. Todd has employed continuous no-till on his 450 acre corn, soybean and wheat operation for 22 years and used yield mapping for more than 14 years and is a strong advocate for doing what he can to help water quality and “still stay in business.”

“Our water infiltration rates for heavy rains, we can definitely see an improvement in the quantity of rain water we can accept and not have standing water or running water off the service,” he said. “That’s the biggest improvement we see is soil health and soil quality.”

Listen to my interview with Todd here: Ohio No Till Farmer Todd Hesterman

To show the clear difference between tilled and no-till soil, USDA-NRCS Ohio state agronomist Mark Scarpitti did a little demonstration on Todd’s farm by dropping a chunk of soil that had been in no-till for several decades, compared to a similar chunk of tilled soil. You can see what happens in the video below.

As Ann Perry reports:

Wheat farmers in eastern Oregon and Washington who use no-till production systems can substantially stem soil erosion and enhance efforts to protect water quality, according to research by USDA scientists. Agricultural Research Service (ARS) hydrologist John Williams led a study that compared runoff, soil erosion and crop yields in a conventional, intensively tilled winter wheat-fallow system and a no-till 4-year cropping rotation system. ARS is USDA’s chief intramural scientific research agency, and this research supports the USDA mission of promoting sustainable agriculture.

No-till production left the soil surface intact and protected pore space beneath the soil surface, which allowed more water to infiltrate into the subsoil. In addition, there was no significant yield difference between the no-till and conventional till production, and direct seeding in no-till production saved fuel and time.

Researchers with the University of Missouri have found a way to reduce the amount of greenhouse gases emitted by agricultural operations, while increasing the yields of the crops. And precision agriculture equipment is playing a key role.

Research agronomist at MU’s Greenley Research Center in northeast Missouri Kelly Nelson says that ag operations in the U.S. create 58 percent of the world’s nitrous oxide, a greenhouse gas that contributes 300 times more to global warming than carbon dioxide. His work is focusing on the placement and source of fertilizers to reduce that nitrous oxide number.

“The fertilizer placement for a no-till system would be, for dry fertilizers, would be broadcast applied over the soil surface. We thought with a strip-till system we can till a small area, usually about 12 inches wide, usually less than 30 percent of the field, and maintain good soil cover, and apply that fertilizer in a band right under the plant so it has easy access to the fertilizer.”

He says using an enhanced-efficiency polymer coated urea and non-coated urea, they were able to test in a clay pan soil, where there is very poor internal drainage and fertilizer loss can be substantial.

“We saw that over the entire growing season, we were emitting about 2.4 to 3.8 percent of the nitrogen applied as nitrous oxide.” Nelson says that while it doesn’t seem like a big number, it shows how much greenhouse gas can be emitted into the atmosphere. Plus, he says this system was able to increase yields. “We were seeing that our strip-till system was increasing yields by about 50 bushels to the acre (in corn), compared to our no-till system.” And it reduced greenhouse gas emissions by about 25 percent, compared to no-till systems.

Nelson admits that they didn’t compare the amount of emissions for running the extra equipment in the strip-till versus no-till operation, but that would be a comparison of CO2 emissions, and as stated earlier, much less impactful when you are considering greenhouse gases. Plus, the increased yields should help make up any differences by increasing the amount of carbon sequestration going on in the higher yielding strip-till operations.

He credits new, advanced precision agriculture equipment and practices for even making this kind of work possible.

“Getting the right product at the right time in the right place, that’s what we’re working toward. Precision ag is moving us in that direction.”

Corn and soybean growers in Ohio and surrounding states should definitely attend an excellent late-February conference to pick up great information that can improve their farm operation.

The Conservation Tillage and Technology Conference is the largest, most comprehensive program of conservation tillage techniques in the Midwest. About 60 presenters (farmers, industry professionals, and university specialists) from around the country focus on cost-saving, production management topics. The conference is broken down into tracks covering soil and water; nutrient and manure management; advanced scouting techniques; cover crops; crop management; and planters and precision agriculture.

This will be the third year for Corn University and the second year for the Soybean School, both of which cover the latest in corn and soybean management from the top researchers and industry specialists across the Midwest.

“Both programs are a main draw,” said Randall Reeder, an Ohio State University Extension agricultural engineer and an organizer of the conference. “Last year, we had about 300 to 400 in attendance at each program interested in learning the latest in crop production techniques to get the most economic yields with conservation tillage.”

Corn University will take place on Feb. 24 from 11 a.m. until 5:50 p.m. and will feature Peter Thomison, an OSU Extension corn agronomist; Bob Nielsen, a Purdue Extension corn specialist; Fred Below and Laura Overstreet, University of Illinois; and Chad Lee, University of Kentucky.

The theme will focus on achieving 300 bushels per acre using a variety of production management techniques from strip-till to nutrient management to fungicide use. Corn University is supported by Dekalb/Asgrow.

Soybean School will be held on Feb. 25 from 8:30 a.m. until 4:50 p.m. and will feature OSU Extension Specialists; Missouri farmer Kip Cullers, who set the world soybean production record this year of 160.6 bushels per acre; Shaun Casteel of Purdue University; Vince Davis of University of Illinois; and Shawn Conley, University of Wisconsin. Pioneer and Seed Consultants support Soybean School.

Other sessions taking place at the Conservation Tillage and Technology Conference include a daylong session on cover crops on Feb. 24, a daylong session on nutrient management on Feb. 25, and a half-day session on Feb. 25 on soil and water, which will include discussions of phosphorus and nitrogen management related water quality, including algal blooms.

Crop Certified Advisor credits be will offered during the Conservation Tillage and Technology Conference, including coveted nutrient management and soil and water credits.

“CCAs can get all the credits they need in both of these areas in just two days,” said Reeder.

Elwynn Taylor, Iowa State University agricultural climatologist, will be the speaker for the opening general session at 9:30 a.m. on Feb. 24.

The Conservation Tillage and Technology Conference broke an attendance record in 2010 with 966 farmers, crop consultants and industry representatives attending the event. Farmers valued the education they received at $13 per acre, roughly a $7 million value. Crop consultants placed a value on their educational experiences at $16 per acre for the land they influence.

The event will be held Feb. 24-25 at the McIntosh Center of Ohio Northern University in Ada. Sponsors include Ohio State University Extension, the Ohio Agricultural Research and Development Center, Northwest Ohio Soil and Water Conservation Districts, USDA Natural Resources Conservation Service, USDA Farm Service Agency, and the Ohio No-Till Council.

Early registration is $50 for one day or $75 for both days. At the door, registration is $60 for one day and $85 for both days. Complete registration and program information will be available after Jan. 1, 2011 at http://ctc.osu.edu.

If your farm operation needs precision farming equipment that can help manage water, check out the new Trimble AG GCS200 system.

Specifically designed for land leveling and drainage applications, it works in conjunction with a laser transmitter to provide automatic machine control of implements such as scrapers and drainage machines, helping farmers to manage water on their fields regardless of crop type or water requirements.

The system is ideal for implements with PT valves, and can use either dual rigid mast control, or single electric mast control. Key components include the LR410 laser receiver and the new CB60 control box, providing a digital elevation display that can be used in both survey and control modes.

The CB60 control box delivers greater flexibility than its predecessors with configuration options for both surveying and grading. Owners of existing control systems can use the CB60 box as a drop-in replacement product, so customers with existing P.A. Laser Grade Control systems do not need any new cables or components.

The AG GCS200 system and the CB60 control box are compatible with English or Metric units and can be used with several types of laser controlled water management and field-leveling products.

“Drainage and leveling professionals have experienced that through the use of laser-guided leveling and drainage equipment, they can substantially improve productivity and accuracy as well as provide the grower with increased crop yields,” said Erik Arvesen, vice president and general manager for Trimble’s Agriculture Division. “Now, the AG GCS200 makes it easier to keep laser-leveling equipment operational and productive on scraper and drainage type implements in the field.”

The AG GCS200 system and the CB60 control box are available now. Contact a local Trimble dealer at: www.trimble.com/locator for more information.

Northern Illinois corn and soybean grower Todd Glendenning says he saved an estimated $1,200 per day during spring planting with his Trimble guidance and row control system, according to a story in the June issue of Trimble’s StraightTalk newsletter.

“After planting with RTK and implement guidance, I would
never want to plant any other way,” says Glendenning. “I used
to spend a lot of time looking back, and trying to compensate for the planter sliding down sidehills, but now I don’t have to.”

Glendenning also added Tru Count air clutches to all 24 planter row units. “We have countless acres of point rows and waterways, so we used to have a lot of overlap and wasted seed. With all the multiple-trait seed we plant, seed costs are around $125 per acre. I’d estimate we saved $1,200 in seed costs per day this spring. And since we aren’t overlapping in the headlands, the plants won’t be overcrowded and lodging. That should improve yield.”

Tillage is another benefit Glendenning sees from his Trimble
equipment. “We’ve found WAAS is just not accurate enough
for doing skip rows on 200-acre fields; by the end of the field
you can end up being off by six to seven feet. But if we pair an
EZ-Guide® 500 system with the Ag3000 modem in our tillage
tractor, we can till very efficiently.”

Give farmers a piece of technology and they find inventive ways to use it to benefit their operation. In the case of Newton, Iowa farmer (and Ag Leader SeedComand product specialist) Will Cannon, it all started with the yield monitor and mapping hybrids.

“I like knowing exactly to a row when hybrids and varieties start and stop—especially when you have to switch near the end of a field—so when you analyze yield results you know why the yields went up or down,” Cannon says. “That practice led to conducting strip trials across whole fields. And I often plug in all my hybrid/variety numbers into the monitor before I head to the field so changing numbers and fields is simple.”

And Will does a lot more than just track yields. “Last year we conducted alternate strips across a field to compare no-till and strip-till soybeans. We set up and mapped alternate passes of strip-till in the fall, came back in the spring, locked in with auto-steer to fertilize and plant into the strips, then no-till plant in-between those passes,” he says.

Cannon likes having all that mapped in the spring, because come harvest he doesn’t have to worry about where the combine is in the field. “I can just harvest and not worry about anything else, because I trust the monitor and data gathering.” Then during post-harvest into winter he crunches data. “I really like the capabilities of the SMS software. There are great tools I can use to select which passes across the field I want to analyze and compare. And I learned a lot about what tillage systems work best in specific fields.”

Another data layer is tracking his refuge management acres. I see this as becoming more and more important, as different hybrids change percentage of refuge acres, plus if I get audited I can direct them exactly to where they need to take tissue samples. And exact location is a big help if I need to apply insecticides on those acres,” he says.

Cannon continues to be impressed with the flexibility built into today’s software and data recording capabilities. “You have a lot of features to document things, so you don’t have to remember it all. And as more growers learn the capabilities, they figure out new ways to use it—because what appeals to one grower may be the opposite of what another guy wants. And the history of data that you build up is invaluable in the future.”

Machine-vision cultivation is a commercial reality for vegetable growers, but is it improving integrated weed management in these crops? University of California-Davis research results, that appeared recently in Weed Technology, showed machines gained the upper hand over hand-weeding and cultivation of broccoli and lettuce during times of rainy weather.

Hand-harvested crops such as broccoli and lettuce are easily threatened by weeds. Uncontrolled weeds can result in lower yields, reduced quality, and decreased harvest efficiency.

The job of cultivating between delicate rows of vegetable plants can be done more precisely and faster with machine guidance. A computer processes 25 digital photos of a crop row to determine the centerline.Previous studies have shown higher rates of error in human-guided cultivation.

The current study timed how long it takes a laborer to hand-pick weeds versus machine cultivation. It also tested whether smaller amounts of herbicide or none at all could be applied to the crop with the use of machine cultivation. Reducing the use of herbicides would have economic and environmental benefits.

The many variables at play produced mixed results. Herbicides proved the most effective method against weeds. But with the heaviest use of herbicide tested, the lettuce yield was not improved—the herbicide also affected the crop’s growth. In rainy weather, when both hand weeding and machine weeding are difficult, herbicides again provided the best weed deterrent. In dryer seasons, machine cultivation was more effective than hand weeding.

In California and Arizona, lettuce and broccoli are grown year-round, and cultivation is an important part of the process. More accurate and timely cultivation may be the greatest benefit that machine-guided cultivation has to offer.

Designing field terraces will soon become easier thanks to a new Internet-based terrace design tool under development at the University of Missouri.

Allen Thompson, Associate Professor of Biological and Agricultural Engineering, says his computer-assisted tool can upload GPS-based topographical data to facilitate design and installation on complex fields.

Another benefit, aside from cutting the terrace development process in half, is the ability to develop several designs to compare costs, conservation effectiveness and farmability based on boundaries, row spacing, equipment size, water flow and other considerations.

More details are in the September issue of Resources magazine, compiled and published by the American Society of Agricultural and Biological Engineers.
