For farmers who deal with the planting and spraying challenges of farming on contours, terraces and hills, there’s a new guidance pattern from Ag Leader Technology that offers help.

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. Updates can be downloaded from www.agleader.com, under ‘Customer Support’. http://www.agleader.com/customer-support/

The new John Deere SeedStar XP monitoring system allows producers to monitor and adjust a wide variety of planting operations on-the-go for optimal seed placement and increased productivity.

“Everything that customers said they wanted in a fully integrated monitoring system for planting operations went into the SeedStar XP system,” says Chris Savener, project manager, planters, for John Deere Seeding.

“This includes an easy-to-read, at-a-glance screen with seed skip information and data on row-unit ride dynamics, which are critical to monitoring and maintaining overall planter performance at the row-unit level. Ultimately, the SeedStar XP monitoring system helps ensure that every seed is planted to the correct depth and spacing within the seed furrow across the entire field. Tests show that the system helps producers save planting time and seed while maximizing yields.”

The GreenStar 2 compatible SeedStar XP system features a user-friendly, full-color planting monitor, or it can be integrated with a producer’s existing GreenStar 2 display to eliminate clutter in the cab. The system is supported by a series of row-unit sensor nodes and downforce sensors configured to the specific model of planter. In addition to the features of the original SeedStar 2 monitoring system, the SeedStar XP system includes these enhancements:

• Seed singulation and seed spacing monitoring
• Row-unit downforce monitoring and adjustment
• Row-unit ride quality monitoring
• Overall row-unit and planter performance monitoring
• Split-screen applications for planting and guidance (AutoTrac)

The SeedStar XP system is available on select model year 2011 John Deere planters, including the 1770NT, 1770NT CCS™, 1790 and DB Series planters, and is fully integrated and compatible with other Ag Management System products used for planting, such as Swath Control Pro for planters, GreenStar AutoTrac assisted steering and Apex farm management software.

Anytime I hear a grower mention best corn planting in 38 years, my ears perk up and the brain wonders why? Then you hear corn seed savings of 45 bags of seed, or $9,900. Wow. I’m beginning to understand this best year deal.

Franksville, WI, grower Mike Borzynski attributes his personal best in the field due to his investment in the new Ag Leader ParaDyme steering system with the INTEGRA display. He used the system on part of his 3,500 acre grain and 4,000 acre vegetable operation—along with another 1,200 acres of custom work.

Borzynski used the INTEGRA to run the SeedCommand with his ParaDyme system to achieve those seed savings over 1,240 acres of corn. And after these results he plans to plant other crops with it in the future. “The ParaDyme worked great. After the first week using it, I bought another one,” he says. Using multiple ParaDyme systems on his operation, Borzynski is confident that he’ll see even more reduction in his input costs in the future.

The ParaDyme automated steering system can be easily transferred from one piece of equipment to another. This allows growers like Borzynski to utilize the ParaDyme not only for planting, but also for application and harvesting.

His next trial is moving this system into his John Deere 7230 tractor, using DirectCommand and his pull-type sprayer to reduce application costs. When asked if he would recommend ParaDyme to a friend or neighbor, Borzynski says without hesitation, “Absolutely. I believe in it 100 percent.”

The ParaDyme automated steering system can be used with the INTEGRA or EDGE display, and offers its users a wide range of benefits for their precision ag operations. For more information about the ParaDyme steering system, visit www.agleader.com.

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.”

It’s nice to see more ISOBUS compliant electronics on equipment, such as with the new Case IH Precision Air 3580 air cart. All systems can be controlled and monitored from the cab thanks to ISO 11783 compliant electronics–such as the Case IH AFS Pro 600 or AFS 300 display.

Engineered for large acreage small grain growers who need to cover thousands of acres in a short planting window, the Precision Air 3580 has a three-compartment tank with a total capacity of 580 U.S. bushels.

The three tank compartments hold 135 bushels, 183 bushels and 262 bushels respectively, providing growers with more seeding and fertilizer options and higher capacities in one pass. Tanks are made of steel, with tough, powder coat paint inside and out for a harder finish, better rust protection and longer wear.

“Our broadacre customers are asking us for larger drills and carts with more capacity, so they can run longer between stops,” says Gord Engel, Case IH seeding product manager. “The less time farmers spend re-filling seed and fertilizer tanks, the more acreage they cover during the prime planting window, and the more they reduce seeding costs.

“Whether you’re growing wheat, barley, rye, oats, canola or pulse crops, the further north you go, the smaller the planting window gets,” Engel adds. “Planting at the right time helps maximize yields. With the Precision Air 3580, growers cover more acres per hour, per day, per week and per season.”

60-inch corn

Ag Leader’s Paul Rose blogs about his trip to South Africa, where the company installed its first ParaDyme system in that country. The 5,000 acre farmer featured in the story plants 60-inch corn that, moisture permitting, averages 80 bushels per acre.

Long narrow fields can enhance field operation efficiency

While driving back and forth across field after field planting seed, spraying or spreading fertilizer, have you thought much about ways to make that task more efficient?

Obviously, if you have auto steering, you’re saving passes due to reduced overlap. But have you thought about turning time, wheel traffic pattern, shallow secondary tillage, harvest efficiencies and other uses of precision agriculture? Check out these ideas from a recent story by university extension specialists.

Turning time
To reduce turning time, farmers should strive to make fields large, long, and narrow by eliminating fence rows, ditches, or other barriers. Larger implements, if matched to tractor size, can be more field efficient because bigger implements cover larger areas and require a smaller number of turns.

Tillage direction
The concept of going “catty corner” or “tilling off the corners” of the field when tilling diagonally can also save fuel by having the turning result in a tillage operation.

Wheel traffic pattern
Controlled wheel traffic patterns can save fuel and reduce total soil compaction in a field. The tractor and other machinery operate in the same tracks for all operations, improving tractive efficiency with compaction occurring only in a narrow area.

Crop growth in the uncompacted areas of the field is considerably better than if some compaction occurred all over; however, poor drainage or other problems may occur near the compacted zone.

Shallow tillage
Deeper tillage results in greater fuel use. With every inch of increase in moldboard plowing depth, approximately 0.15 more gallons of diesel fuel per acre is used. There is a proportionate increase for other tillage operations at increased depths. Secondary tillage should seldom be performed deeper than one-half the depth of primary tillage.

For example, if a field is plowed 8 inches deep, disking should be no deeper than 4 inches. Shallower secondary tillage has the added benefits of not only saving fuel, but reducing compaction and lessening the amount of wet soil and weed seeds brought to the soil surface. Water loss is also often reduced with shallower tillage, resulting in a longer period before first irrigation is necessary and/or better overall early plant growth.

Harvesting efficiency
Crop conditions can affect the amount of fuel used in harvesting operations. A crop which is too wet, lodged, or harvested under wet soil conditions can increase fuel consumption. Where possible, under optimum crop and field conditions, proper machine adjustment and harvest can result in fuel efficiency. Harvesting less straw and stalks during grain combining by increasing height of cut can reduce fuel consumption as well.

Use of precision agriculture
Global positioning system (GPS) guidance systems and auto-steer technology make use of the most efficient routes around a field, eliminating overlaps and skips.

We’ve written before about economic savings derived from auto steering and auto planter row shut-off off. But many growers often favor the aspects of increased productivity with less fatigue at the end of the day.

We spoke with Adam Gittins, Precision Ag Sales Manager for HTS Precision Ag Solutions in Harlan, Iowa, about the current planting season and local farmer philosophy on this subject.

“Farmers, and I’m one of them, often apply two schools of thought regarding productivity and planting season—auto steer and auto shut-off,” Gittins says. “First, adding auto steering allows growers to run later at night with less fatigue and still be every bit as accurate as planting during the day. Second, by adding auto row shut-off to the planter, guys are saving time with quicker turn time at the headlands.”

Farm more acres. Running longer hours combined with quicker turns can help growers farm more acres with the same equipment. “We’ve seen operations add farm land, and instead of buying another tractor and planter, they’ll instead buy auto steering and planter shut-off to increase productivity—and be able to farm 20 percent more ground with the same equipment,” he says.

“It so much less stress when you don’t have to stare at a marker furrow all day. And I feel I’m doing a much better planting job because I can swivel my seat part way around and watch row units and planter attachments, and can make quick adjustments as needed—instead of focusing mostly on driving. And I feel so much better physically at the end of the day,” he adds.

Becoming standard equipment. Gittins cited one extreme example from this past winter where a farmer saved money by buying an auto steer unit instead of paying for markers on a new 90-ft. planter. “Another trend we’re seeing is that guys who purchase new tractors won’t wait and add auto steer later, they put it in now.”

While good weather is really helping a lot of farmers get crops in the ground quicker this spring, any grower with auto steer and auto planter shut-off will tell you how this technology has truly helped them improve their entire planting operation.

UPDATE MAY 3 — In case you missed this chat – visit Truffle Media who posted the entire convo.

Several farmers who use the social media Twitter are holding a one-hour chat about precision agriculture this Friday April 30th at noon Central.

According to Daren (@kansfarmer), topic will be precision ag, with a focus on planting precision-related topics and issues. We will use the #agtech hashtag for the chat. Format will be similar, although abbreviated from the standard Tuesday evening #agchat that takes place. Some guidelines on how AgChat works available here: http://michelepaynknoper.com/agchatguide.html. Everyone will be asked to give an introduction at the start, and a few minutes in we will open with first Q – give 10-15 minutes for discussion of that question, than move to the next one. Hope to see you there.

There is a regularly scheduled weekly agchat that usually attracts over 100 participants from diverse backgrounds and covers wide range of ag topics. We decided to try this more narrow-focused chat at least once. If you are unfamiliar with Twitter and do not have an account setup, you can still go to the www.twitter.com homepage and enter #agtech as the search term and see the chat as it happens.

This short chat is being organized by Daren (@kansfarmer) and Brandon Hunnicutt(@cornfedfarmer). Not a lot of ag technology activity on Twitter right now, but both Ag Leader and Raven have active accounts, have seen a handful of ag tech service providers, and several NeATA folks.

I have not met a grower involved in precision agriculture that doesn’t love, no crave, more information on the subject. To this end, check out the very good Precision Ag Blog, compiled and written by various extension pros in the Alabama Cooperative Extension System.

Recent blog posts talk about variable rate (VR) seeding, VR calibration, data management, data collection with cellular modems, the value of on-the-go nitrogen sensors, firmware upgrades and much more.

The blog site also categorizes posts into topics to help you sort for exactly the info you seek.

If you’re looking to experiment with corn planting populations yet this spring, check out a very good paper on plant population compiled by South Dakota State University researchers Gregg Carlson, Paul Gaspar and David Clay.

Many agronomists and producers conduct experiments that test the impact of rates of fertilizer, population, or pesticide on yield. To analyze this data we need to conduct a yield response analysis. Agronomists and or producers that understand yield response and how to use yield response to determine the point of optimum economic return will be able to make better management decisions. The point of optimum economic return is determined by:
1. Conducting a yield response experiment
2. Converting the yield response data to a functional relationship,
outputcorn yield = f(input the plant population)
3. Using calculus to determine where the change in the value of the input equals the change in the value of the output.
In site-specific farming, scientists have found that yield response relationships may change spatially and temporally.

To learn more, read the paper “Using Yield Response Analysis to Calculate an Optimum Plant Population“.

The Furrow magazine, produced by John Deere, profiled several growers on their use of precision farming management zones in a story called “Farming In The Zone” in their March 2010 issue.

Broadwater, Neb., grower Frank Lussetto says zone management helped him accomplish three broad goals of being agronomically sound, economically smart and environmentally safe. He uses zone maps for phosphorous, nitrogen and seeding rates, grouping six to eight soil types in a field into three to five zones. And he used elevation and electrical conductivity as the primary drivers in zone development.

The story also featured Enterprise, Kan., farmer Larry Hottman and his use of zones, derived more prominently from yield maps collected since 1998. He too used electrical conductivity readings to map soil properties along with grid soil sampling.

University of Nebraska agronomist Richard Ferguson says they are seeing a $26 per acre benefit using site-specific nitrogen application and zone management.

For more details, read the story.

While every farmer knows the value of preparing and calibrating the planter and sprayer, the same holds true when calibrating the electronics and software that control these implements—especially if you vary rates across the field on the go.

Hopefully you pulled out that owner’s manual, or enlisted your local dealer’s help, several weeks ahead of pulling into the first field with a planter full of seed. “The equipment only works as well as the set-up, so running the calibration software on your monitors should be an annual event,” says Nick Ohrtman, Technical Support Supervisor for Ag Leader Technology.

Since there’s no real standard procedure when calibrating for variable-rate technology, it is critical that you follow the guidelines in the owner’s manual of both the piece of equipment and the monitor that is driving it. “Our display monitors, like the Insight or INTEGRA, have a calibration wizard that walks you through seed meter calibration, allowing you to count the actual seed that drops per revolution, which is critical for variable-rate seeding” he says.

“If your variable-rate monitor is set to plant 34,000 seeds and the population monitor says you’re only seeding 30,000, then that’s a sign that the calibration was done inaccurately. If this happens with our system, when both monitors are running through our display, an alarm sounds when the populations don’t match up,” Ohrtman adds.

Granted, most calibration settings made are saved by crop, but it is still wise to recalibrate every year for each crop. “Once you’ve calibrated for corn and soybeans, then every field will use the same calibration. And the calibration doesn’t change when you’re switching plant populations,” he adds.

For growers using planter section or row shut-off technology, it’s advised to make sure your settings are correct each year. “With our AutoSwath system, there are three different settings available, so it’s wise to check the owner’s manual every year, as well as do a dig check in the soil on the first round to make sure the row shut-offs are working correctly.” Nick talks about tips for using AutoSwath in his blog post here.

Variable Rate Equipment – Technology for Weed Control

Gear Up For VRT (Farm Journal, March 2009)

Agriculture.com, one of the longest running ag websites powered by Successful Farming, has a social network for young and beginning farmers called Farmers For The Future. One of the recent topics centered around precision farming talks about a move into RTK and the CORS network.

The challenge is dealing with all ages and different colors of equipment. Sam asks…We have three green combines 1 newer the 2nd is 10-11 years old and the other is a dinosaur and the newer one being the only one with yield mapping through waas signal using original brown box from JD ( never right ). Next we have 2 Planting tractors both have 20/20 seed sense systems from precision no GPS. Sprayer we have a XLRD 1000 Pull Type pulled by a JD 4430 with a INSight and an EZ-Guide 500 waas signal. Spreader truck we have a Insight along with EZ- Guide Plus. Now I must say that it looks like we just put a down payment on a 06 Apache with auto steer by Raven. Also a new red combine is probably coming this fall 8120 Case and we are talking about buying a new corn planter also.. we put a lot of tile in we bought a tile plow.. No GPS also we have a 8530 JD autosteer ready for doing a lot of tillage and side dressing corn with anhydrous. 9520 T John Deere does a good majority of the tillage and also runs the tile plow. Now you see my situation figure out a plan for that to move into RTK.

Several growers have responded here.  Take a visit and weigh in with your advice.

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.”
