Fall Release of SMS Mobile Software http://www.agleader.com/2010/07/19/ag-leader-announces-fall-release-of-sms-mobile-pc/

German company RapidEye, the only geospatial solutions provider to own and operate a constellation of five identical Earth Observation satellites, announced today that over a period of just three months, 95% of the contiguous United States has been imaged. Almost 80% of this imagery was captured by the RapidEye satellites with less than ten percent cloud cover.

The campaign, which began May 1 and was completed on July 31, produced an abundance of imagery with many areas covered multiple times. Not only the United States was covered; 97% of Mexico was collected and almost 60% of Canada. Many areas were imaged more than once over this three month span and totaled 17 Million square kilometers of North America. All of this imagery is currently available for purchase in the RapidEye Library.

The company also has released a success story with the French precision farming company S2Bvisio about how RapidEye has delivered nitrogen fertilization maps for canola and wheat fields for the customer. You will find details about this project at http://www.rapideye.de/upload/documents/References/Customer_Reference_S2B_08_06_2009_ENG.pdf.

RapidEye images the Earth in unparalleled quantities and will continue to make its satellite imagery available through its Library, which can be searched either through a local distributor or directly through its Customer Service department. To find a distributor visit the RapidEye website at www.rapideye.de/distributors. Additionally, a selection of RapidEye products can be searched for, purchased and immediately downloaded through the RapidEye Geodata Kiosk at www.geodatakiosk.com.

Despite the heavy rains at times followed by high heat and humidity, around 800 growers, retailers and crop consultants came to Farm Journal test plots near Bloomington, Ill., to gain in-depth knowledge from experts at the recent Farm Journal Corn College.

During this week-long classroom and in-field event, hosted by Farm Journal field agronomists Ken Ferrie and Missy Bauer, participants gained hands-on information about such topics as planter impact on root growth and development, variable-rate population and nitrogen, the significance of water pH on herbicides, lime quality and application methods, and much more.

Ag Leader Technology was one of the sponsors of the event, and the company hosted a luncheon ‘Learning Session.’ “We talked about crop sensor technology from A to Z—from helping growers understand how the technology works to what farmers need to consider when adding the technology to their operation,” says Jessica Reis, Marketing Communications Specialist for Ag Leader.

“It was an excellent dialogue with growers, who helped remind us how cutting-edge this nitrogen sensor technology is from their perspective, which is different from those of us who deal with it daily,” Reis says. “We talked a lot about how growers can add sensors to gauge crop health during a postemergent herbicide application, as well as how the sensors, such as our OptRx Crop Sensor, can be incorporated into a nitrogen application program. It was a great learning session for us as well as the growers.”

Sponsors of the event also participated in a trade show area to answer any and all questions. “We had a lot of questions about planter section control, such as our SureStop Clutch and SureVac Shutoff, to help grower save seed costs,” Reis says. “Data questions, such as how to analyze years of collected data for improved management decisions, were very popular. We helped growers understand the benefits of our SMS Basic and Advanced software, and how it can work with data from many types and colors of equipment.”

Producers came to learn at the recent Precision Ag Expo field days held recently in North Dakota. Numerous questions, according to a story in Farm & Ranch Guide, aimed at gathering facts about zone maps, satellite imagery and variable rate precision farming.

Kelly Sharpe, of GK Technology, Inc., in Halstad, Minn., said his company creates variable rate mapping, taking an image from a field and creating zones based off of this input image.

Zones are soil sampled and fertilizing and seeding maps are created. The producer receives a prescription that he can input into his GPS system to apply fertilizer and seed at the correct rates while traveling across the field.

“Economics has forced us to make more money off the same acres,” Sharpe said. “There’s a lot of variability in every field caused by topography and soil types. Maps can show you where there might be more leaching of nitrogen or different soil types requiring different treatments.”

“You could put 30 pounds of nitrogen on the top of your hills and 90 pounds on the bottom of your valleys and it might not be accurate,” he said. Zone mapping is the solution to putting on the right amounts, and it can be done “right from the cab,” Sharpe said.

Check out this piece to learn more about the benefits of satellite imagery and variable rate manure application.

ARS researchers have developed a way to make more precise agricultural maps of fields from data generated by LIDAR (light detection and ranging) sensors to help farmers target more of their resources to the highest-yielding parts of their fields. Graphic courtesy of James M. McKinion, ARS.

Using an airplane with LIDAR (light detection and ranging) sensors is helping USDA-ARS researchers build better management zone maps that can accurately predict yields based on topography.

With the maps fed into computerized, variable-rate fertilizer applicators, precision farmers can divert more of their costly fertilizer to the highest-yielding zones and the least to the lowest-yielding zones. They can also use the zone maps to make other decisions, such as planting more drought-tolerant varieties in low-yield zones, or sowing less seed.

Five years of comparisons between these maps and actual “on-the-go” yield monitoring for cotton and corn on a farm in Mississippi showed that accurate yield predictions can be made based on topography.

Researchers contracted to have a plane with LIDAR (light detection and ranging) sensors fly over the 1,000 rolling acres of the farm. LIDAR is a form of radar that can map elevations digitally, showing slopes and sun exposures, by bouncing laser light off the landscape.

By blending yield results with the maps, the scientists divided fields into high-, medium-, and low-yield zones.

One advantage of LIDAR landscape mapping is that it only has to be done once.

LIDAR topographic mapping is spreading from state to state. Louisiana, for example, has financed LIDAR mapping of the entire state.

Otherwise, it is expensive for an individual farmer to pay for LIDAR mapping. So, McKinion is also looking for alternative topographic mapping techniques.

James McKinion, an electronics engineer at the ARS Genetics and Precision Agriculture Research Unit at Mississippi State, Miss., did the study with entomologist Jeff Willers and geneticist Johnie Jenkins at the ARS unit in Mississippi. This research was published in Computers and Electronics in Agriculture.

ARS is the principal intramural scientific research agency of the U.S. Department of Agriculture (USDA). This research supports the USDA priority of promoting international food security.

When discussion centers around all the data that fields can generate these days, crop consultants and savvy growers truly love powerful software programs. Especially when data can transfer easily between desktop and a mobile device to take to the field.

I spoke with Greg Kneubuhler the other day, who is a certified crop consultant, agronomist and owner of G&K Concepts in Harlan, Ind. Greg has been a true pioneering consultant in the NE Indiana/NW Ohio area—starting growers down the precision farming/yield gathering path back in the late 1990s. Today, his clients’ business has evolved into intensive precision management that includes precise zone management and applying the right variable-rates—all driven by on-farm research on every farm. To help accomplish such research, Greg works on numerous projects in cooperation with Joe Nester of Nester Ag, Bryan, Ohio.

“We’ve always used a zone management philosophy in fields—which started with soil types. Then we added yield and soil test data layers to begin developing variable-rate applications of nitrogen, lime, and even seed by management zones. But an accurate yield map is critical,” he says.

Kneubuhler, who has used various software over the years, now relies on SMS Advanced software from Ag Leader. Its data layering and management zone capabilities, along with its smooth data transfer between the SMS Mobile software on a handheld computer.

“I’m a daily SMS Advanced user, and I have yet to find a software that is better. If there was one, I’d be using it. I can manage all clients zones, all research trials, and easily sync data to SMS Mobile so I can use it to walk corn fields to exact locations for stalk nitrate tests or to check on potential issues that show up on aerial imagery,” he says.

These valuable information tools help Kneubuhler take all the geo-referenced data his clients collect, which he layers into his ‘sandwich.’ “As an agronomist, we use this tool to build a sandwich of every type of information we can gather—and that really helps us make very good management decisions today, and down the road.”

University of North Dakota students and faculty designed and built the ISSAC camera to watch growing crops from space beginning in 2011.

“ISSAC is a space-related research project that will result in the delivery of direct benefits from space to the general public,” said Doug Olsen, ISSAC project manager. “The ISSAC project is in the midst of developing an upgrade to its camera sensor, which is expected to be launched in April 2011. It will resume operations during the 2011 growing season.”

ISSAC is designed to take frequent images, in visible and infrared light, of vegetated areas on the Earth, principally of growing crops, rangeland, grasslands, forests, and wetlands in the northern Great Plains and Rocky Mountain regions of the United States. Images will be delivered within two days directly to requesting farmers, ranchers, foresters, natural resource managers and tribal officials to help improve their environmental stewardship of the land. Images will also be shared with educators for classroom use.

The system allows users to select specific geographical areas of interest over which to request collection of imagery in both red and near-infrared bandpasses, and at medium-high spatial resolution. Farmers using variable-rate application and other precision agriculture techniques will be able to dynamically delineate management zones as the crop vegetation canopy changes during the growing season; this can result in more effective use of fertilizer and other chemical inputs and reduce negative environmental effects.

“The UND interdisciplinary effort that has produced this camera is a remarkable story,” said UND President Robert O. Kelley. “Faculty and students from several colleges and centers on campus have produced an instrument that will analyze the composition of agricultural and other natural resources on the surface of the earth from the International Space Station.”

“The consolidation of multiple technologies into a single instrument will add tremendous economic value to the agricultural industry in North Dakota and around the world,” Kelley said. “UND and NASA have forged a very productive partnership in this initiative.”

ISSAC is operated from the Science Operations Center (SOC) on the UND campus, staffed by students from across the campus, including from the John D. Odegard School of Aerospace Sciences and the School of Engineering and Mines. From the SOC, students will send commands to ISSAC to take images and transmit them to SOC, where they’ll be processed and delivered to end users. Images captured by the camera will be made available to the public through UMAC’s Web page (see http://www.umac.org/).

This flexible, web-based system allows users to manage moving and stationary equipment, and to manage field data work orders. In addition, it provides a comprehensive reporting system.

As planters continue to roll across the Midwest, most farmers are thinking about what’s next. One component of precision farming you may want to try is the use of crop sensing. Why? Because this is the future that will help overcome field variability–from helping create optimum field management zones to monitoring crops so growers can take action before yield-robbing stress occurs.

One good overview of this science, published in 2003 by USDA-ARS scientists from across the country, will help you grasp the realties and benefits that can be achieved. And the technology has dramatically improved since this was written.

One independent agronomic guru who is a favorite of mine (and I’ve quoted many over the years in farm magazine articles) in Tom McGraw, owner of Midwest Independent Soil Samplers (MISS). Tom calls a spade a spade, and offers some excellent advice, which he gives in his newsletter, on their website, and especially to customers.

Bottom line is you should consider examining one field, perhaps your toughest most variable ground, to see what you can learn and improve upon with this sensing technology. Talk to your local retailer to understand their capabilities, or contact one of the four MISS locations.

You won’t find too many farmers who would disagree with the notion that corn plant health can vary widely across a field. And I think the majority of growers would love to improve their nitrogen fertilizer use efficiency—if only the weather would cooperate.

While variable rate fertilizer based on grids/management zones and soil tests is one possible solution, that practice cannot account for heavy spring rains—all too familiar to growers in some Midwest states during the past two years. These events caused a lot of N loss through nitrification, runoff and leaching. Peter Scharf, University of Missouri Extension agronomist estimated that 70 million bushels of corn were lost in his state in 2008, and even more was lost in 2009.

However, using sensors to read and apply the correct amount of N a plant needs at V6 growth stage is a technology that is beginning to catch on. But in order to reap potential benefits, growers must be willing and able to apply one-third to one-half of their target N amount pre-season, then come back and sidedress, feeding the healthy plant less and the weaker plants more.

A handful of companies have developed the technology, with Ag Leader Technology being one of them. Over 100 side-by-side comparison tests (sensor-applied versus grower’s normal flat rate) at the University of Missouri USDA-ARS have shown an average benefit of $15 to $20 per acre with sensors. Ag Leader trials with their OptRx crop sensor system delivered $50 to $60 per acre greater return in 2008, and a $22 per acre average return last year.

“We don’t expect such high returns year in and year out, unless high rainfall removes N early on from the profile, like it did in 2008 and 2009 in many areas,” says Chad Fick, OptRx product specialist for Ag Leader. “We have great confidence with the sensor, now it’s all about getting more growers to experience the possibilities in their fields.

Fick says they have conducted trials in Iowa, Missouri, Kansas, Illinois, Indiana, Michigan and Louisiana. “We’ve had good results in all cases except in Michigan where we didn’t get harvested grain data due to the corn being chopped. Most growers applied approximately 60 to 100 lbs N before planting, then came back at the V6 growth stage to sidedress the amount needed by the crop, as determined by the sensors,” he says. “The most important emphasis here is to make sure you have enough N so the crop does not get stressed before V6—because stress before then will cause permanent yield loss.”

To calibrate the sensors, Fick says it’s as simple as driving to the healthiest part of your field and taking a reference strip sensor reading there. “That gives the sensors a frame of reference to what the field is capable of achieving.

Water use efficiency is vital for agriculture as our global population continues to grow. To help growers minimize water use while maintaining crop yields, Cermetek offers the new AquaMon Wireless Soil Monitoring Network.

AquaMon allows active monitoring of the soil. Knowledge of soil conditions is essential to achieve high crop yield with less water.  Maintaining the optimal level of moisture in the ground permits crops to flourish.  Doing so with the minimum amount of water requires real-time data on soil conditions. An AquaMon sensor node can support up to six sensors of any variety including soil moisture content, soil temperature, air temperature, humidity, pH sensors, and nitrate sensors.

In addition to monitoring soil conditions digitally controlled outputs can activate external equipment such as flow valves or nutrient injection equipment.  Much as electronic fuel injection permits automobile engines to increase power while reducing fuel consumption and emissions; real-time soil monitoring allows water conservation without impacting crop yield.

The data generated by AquaMon can be viewed in two ways, locally or on-line.  Cermetek created Remote Sensor Viewing Platform (RSVP) software to allow the irrigation decision maker to load the field data on his computer and easily view the data patterns.  The data can also be uploaded onto our server and be viewed in the same format using a standard browser.  Storing the data on-line allows the data to be viewed from anywhere with Internet access and even allows multiple authorized users to view the same data.

AquaMon is expected to be available this spring.  The cost of a single sensor node is expected to start at $300 plus the cost of the sensors.  Cermetek is actively recruiting Irrigation dealers to resell the AquaMon product line.

Precision farming has come a long way since the military allowed civilian access to the NAVSTAR GPS constellation in 1995. We’ve gone from initial accuracies of tens of meters down to a couple centimeters. And now we’ve got receivers handling multiple satellite constellations, referred to as GNSS (Global Navigation Satellite System).

Topcon Precision Agriculture’s senior VP Albert Zahalka gave a talk recently about how the future of precision ag is here today, and the journey is just beginning. Some of the key points he made:

• Receivers with GNSS technology will have fewer lost signals.
• Today’s precision ag is about three key elements: saving time, reducing costs, and environmental stewardship.
• Future: Massive user interface improvements will make operation simple without the need for a manual.
• Future: Expanded telematics will allow users to remotely monitor critical operating conditions and status of machines whether in a field 5 minutes away or across the globe. You’ll be able to manage your farm from inside your home.
• Future: Autonomous machine operation, already at work in the mining industry, will come to agriculture. Coming safety measures will allow for autonomous driverless machines to work in fields.

In the future, farmers will be increasingly reliant on accurate, dependable statistical information, which will then feed into integrated precision agriculture systems to deliver outstanding productivity and crop yields.

In the not-too-distant future, we’ll have a farmer sitting in his farmhouse, looking at his computer and saying to his wife, “Marge, we are going to do the planting today.”

Then he will press the “planting” button and his tractor (or tractors) will come out of the shed, head off to the fields and begin planting the right seed in the right location, in the right quantities for optimum growth, all with minimal human intervention.

And if there’s a problem or a machine breakdown, the farmer will be instantly alerted.

And as those crops grow and mature, we’ll have sprayers and watering equipment driving along in the farm field. It will see that one plant is not as green or thriving as well as the next, so it will apply a shot of water or nutrient as required.

That vision is still a little way into the future – but it is clearly the direction precision agriculture technology is going.

Read the entire speech.

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.
