Precision Pays

I’d like to introduce the newest sponsor for our AgWired.com website and that’s Leica Geosystems. They are also providing supporting sponsorship here on Precision Pays as well.

Today the company announced that Harlan Little has been named the North American Business Manager for Leica Geosystems’ agriculture group.

Little started with Leica Geosystems in late January, and will be based out of Leica Geosystems NAFTA headquarters in Atlanta.

“Harlan is a great addition to the team and brings with him a wealth of ideas and industry contacts to help grow our business throughout the U.S. and Canada,” said Rob Kiernan, global sales and marketing manager. “We are ready to take our business to the next level with new leadership and a suite of new products being introduced this year.”

Most any photographer will know the Leica name. Oskar Barnack created a small 35mm camera back in 1925 that pretty much changed the way we look at things. What a lot of people are now learning about Leica is that they’re into precision agriculture technology in a big way. The company has three distinct divisions and the one on display at AG CONNECT Expo was Leica Geosystems. It was there that I met with Rob Kiernan, Global Sales & Marketing Manager.

Rob says that since they come from the optical business they’re basically a measurement company that has moved into GPS and that has led them into agriculture. At the show he says they’re promoting their mojoRTK which was launched in early 2008. He thinks they’re just now hitting their stride with the product. Service has been one of their priorities and they offer Virtual Wrench which allows the operator to get help without leaving the cab using mobile phone technology. The newest addition to their product lineup is their mojoMINI which does field guidance as well as standard navigation and will be available starting in February. You can see the unit on the display in the photo.

To give you a better understanding of the CORS (Continuously Operating Reference Stations) Network, Bill Cran, GPS & Guidance Product Specialist at Ag Leader Technology, answered our questions about its use in precision agriculture.

1. Why should a grower consider the CORS network and technology?
• CORS is a service provided by some states, and in most cases is provided free or at a very low cost.
• CORS allows a user to have access to an RTK level correction almost anywhere in the state’s network as long as they have cellular access
• Rapidly becoming accepted at the end user level.
• Companies are adopting this new technology and producing hardware that will take advantage of it.
• Allows growers to have an RTK signal over a larger distance—to cover farms that may be spread out over 20+ miles. A traditional RTK base station would not cover this large of an area without moving the base station or using repeaters.

2. How does it work and what are the pros and cons of this technology?
• CORS is a network of base stations, strategically located throughout participating states. Position information is fed back to a central server where it is broadcast over the internet to anyone with a login.
• A user can create an account with the state and using an internet-enabled device, begin streaming the data to their RTK capable GPS receiver.
• Pro: CORS provides statewide RTK coverage.
• Pro: This service (from the state) is usually free or at a very low yearly cost. Iowa, for example, provides this service free of charge.
• Pro: More states are recognizing this technology and have plans to add a network if one is not already in place.
• Pro: In Iowa, base stations are Glonass capable, which provides better satellite coverage during times of the day when the US GPS satellites may not be enough (5 are required for an RTK fix). The rover receiver would also need to be capable of Glonass to take advantage of this.
• Con: Signal reception is dependant on cellular coverage and limited by the cellular data plan.
• Con: Since the signal is controlled by the state, there is always risk of outages that may not be fixed until the next business day. This is not very common, but it can happen.

3. How can a cell phone signal truly deliver RTK-correction accuracy? Or can I get any level of accuracy? And do I need another cell phone and use package?
• A cell phone with a data plan can use an application to configure the login information and begin streaming data.
• Most Smartphone’s are capable of doing this, but the user should check with their provider.
• Using the CORS technology, you can only stream RTK level accuracy at this point.
• Most users will have a dedicated cell phone or air card that will be used to stream data.
• In general, voice calls take priority over data, so if you are using a personal cell phone to also stream data, you run the risk of drops and disconnects when you receive a voice call.

4. Do I still need to keep my current GPS-corrected signal? What happens if the CORS signal gets dropped?
• If you are using OmniSTAR as your differential signal, you can upgrade a capable receiver to RTK level and use it with the CORS network.
• The receiver must be RTK capable in order to be used with a CORS network.
• The user should not have to keep the OmniSTAR subscription as a backup
• With the Ag Leader ParaDyme, if signal is dropped briefly, the system will continue to steer the vehicle and provide GPS until the connection is regained.
• ParaDyme also uses a “flex” technology that will drop back to the next most accurate differential signal until the CORS connection is regained. This allows the system to keep steering, without affecting accuracy. Since this transition happens gradually, the user does not see any position jumps in the field or with their steering system.
• ParaDyme will automatically try to reconnect if a signal drop is detected.

5. What does Ag Leader offer for hardware to use the CORS network and what are all the costs associated with using a CORS signal?
• Ag Leader offers the new ParaDyme roof array that uses a built-in cellular modem to connect to the CORS network and stream RTK data.
• This allows the user seamless access to the CORS signal with one piece of hardware, no additional cell phones, laptops or any other extra hardware in the cab.
• The ParaDyme user interface allows the user to configure the login information and select which of the CORS network data streams they want to use.
• The ParaDyme uses a CDMA (Code Division Multiple Access) modem that will allow the system to access any CDMA cellular tower (both Verizon and US Cellular use CDMA)
• Using the CDMA modem allows access to more cellular towers and better cellular coverage. CDMA is a digital signal, and it has been around since the early 90’s and is up to 15 times faster than analog technology
• Ag Leader offers a monthly access plan for $300/month. This provides a truly unlimited data plan with no worry of going over your monthly limit and incurring additional charges. It also allows the user to go month-to-month as their situation allows. Not everyone is probably going to use the network 365 days a year.
• Ag Leader also offers discounted 3 and 10 month plans at $750 and $1500 respectively. This gives the user more flexibility to get the work done within their timeframe.

6. How do I get started with setting up a CORS signal?
• First, contact the DOT in your state and see if they have a CORS network or are planning one. Here is an example map of Ohio.
• Second, get access to the network by creating an account. Most states with CORS networks allow you to do all this online. Check your states DOT website for more information.
• Third, configure your hardware, like ParaDyme, using the account information you get from your state DOT. An Ag Leader Dealer will be able to help with any setup questions.
• Finally, connect to the network and enjoy RTK level accuracy without being tied to the traditional base stations distance limits.
• Traditional 900 MHz base stations generally have a limit of 6 miles, line of site. A CORS network generally does not have limits on distance because there are base stations installed and covering the whole state.

Precision agriculture technology is on display all over the AG CONNECT Expo show floor. I don’t think I’ve seen quite so many exhibits outside of a show dedicated to this growing technology application. Raven Industries is one of the companies exhibiting something new here at the show.

I spoke with Marketing Manager, Ryan Molitor,about Slingshot. He says Slingshot represents a breakthrough in connectivity, online services and hardware. It can deliver advanced RTK correction signal technology and high speed internet using wireless in the cab.

Precision guidance, autopilot and other precision agriculture technologies can give farmers yield advantages and input savings when implemented into certain cropping systems, said a Purdue University agronomist.

“Automatic guidance gives producers precision farming capabilities throughout the growing season by allowing them to map tillage operations and crop planting, spraying and harvest, and can help tailor fertilizer and chemical applications to avoid waste,” said Tony Vyn.

The most precise form of automatic guidance, real time kinematic, or RTK, is especially helpful to guide planting in strip-till corn systems. RTK guidance can help achieve precisely parallel strip-till passes in the fall or spring. The same guidance system can ensure the corn planter is centered on the strip-tilled berms, even if the planter is wider than the strip-till unit itself, and even if the berm positions are difficult to see in spring. Planting in the center of the berms helps achieve higher yields, especially in high-residue situations like corn after corn, Vyn said.

“When we’re talking about preplant nitrogen application in the form of urea ammonium nitrate (UAN) in either no-till or strip-till systems, precision guidance allows producers to plant corn either directly on top of the fertilized bands of the soil or at a precise distance away to reduce the risk of corn or seedling injury when higher UAN rates are applied,” Vyn said. “When preplant UAN exceeds 50 pounds per acre, it is safer to plant corn at least 4 to 5 inches to the side. This is another area where automatic guidance gives an advantage because it offers precisely parallel planting abilities.”

But automatic guidance isn’t the only precision agriculture technology that can increase producer efficiency. Take, for example, yield monitors, automatic planter row shut-off and automatic sprayer boom control.

Data from yield monitors can prove a need for tiling and show how it will pay off in specific fields. Both automatic planter row shut-off and sprayer boom control prevent overlap, and thus help producers improve the bottom line by decreasing waste.

The most important aspects of the advanced guidance and other precision technologies are more than just cost alone.

“Sometimes with precision technology, the challenge is for farmers to stay sufficiently alert in the tractor or the combine,” Vyn said. “Although automatic guidance helps farmers to work longer days, and although the improved ability to monitor implement functions helps farmers make fewer mistakes, the guidance technology is no substitute for doing all field operations with sound agronomy.”

When choosing an automatic guidance system, or any other precision technologies, there are a few tips Vyn said producers should keep in mind:

* Assess the farming operation before investing in precision agriculture tools. Decide what level of precision is needed for each field operation, both within a season and from year to year, and what financial benefits the technologies will bring to a specific cropping system.

• Make sure the system purchased has upgrade capability, as new technologies continue to come into the market.
• Less expensive systems won’t save producers as much as the higher quality guidance and monitoring systems.
• Review the compatibility of the precision technologies with the current equipment and planned replacement equipment.
• Look for a dealer with experienced precision farming technicians who can assist with any questions or issues producers may have.

In general, the past year in the world of precision agriculture has been one of consolidation among industry players. “We’ve really streamlined into 4 or 5 major players in precision ag,” says Matt Darr, Iowa State University Ag Engineer.

“Rather than a lot of companies that offer a segment of products, we’re getting down to a core set of companies offering full-service solutions—products for every type of ag operation,” he says

For example, Darr cites the recent Ag Leader and AutoFarm partnership. “And Trimble purchased numerous smaller precision ag companies to fill out their portfolio of products (like Farm Works software, NTech GreenSeeker and Tru Count).”

From a technology introduction standpoint, there haven’t been a whole lot of truly new products in 2009, according to Darr. “The largest growth segment of products has probably been in the area of CORS-compatible GPS equipment. Trimble, Topcon, AutoFarm—they all have CORS-based capabilities,” he adds.

Impact of CORS? There’s more and more grower interest. “I always tell growers that CORS isn’t going to provide a better RTK solution, as the accuracy of a single base solution is still governed by the distance to the base station, just like traditional RTK. What it does is bring coverage to every farmer in the state Iowa (and in other states that have CORS network),” Darr says.

It wasn’t but a couple years ago that it cost $50,000 for an RTK system—not even including the cost of auto-steer. Today, you can get a complete CORS auto-steer system in the tractor for $15,000 to $17,000.

Coming in 2010. Darr says we’ll continue to see expanded interest in CORS network products. “Auto-steer will continue its rapid adoption, because the efficiency, the savings and intrinsic benefits of less stress and greater productivity in the cab will drive sales.”

As the price of agricultural fertilizers begins to increase again, he sees an increased interest in nutrient management and variable-rate products. “There continues to be a need for real-time sensing of nutrients. These products—GreenSeeker (Trimble), OptRx (Ag Leader) and Crop Spec (Topcon)—are still very young in their developmental stages. These technologies have huge potential to make an impact on both the economic and environmental aspects of agriculture,” Darr says.

“The perpetual rising price of seed will continue rapid adoption of the DirectCommand AutoSwath-type products that provide pretty immediate payback on seed and chemical savings. A $300 bag of seed equals $120 per acre seed costs. An auto-steer system and planter unit control will save a minimum of 2 percent (not including possible variable-rate seeding savings), which equates to $2,400 per year over 1,000 acres,” he adds.
