Precision Pays

GM crops and precision farming benefits are being pushed back onto the national agenda in the UK, with the focus to help beat climate change, according to a report in The Guardian newspaper.

Former cabinet  minister Chris Smith, now chair of the Environment Agency, addressed farmers at the annual conference of National Farmers’ Union, saying that “climate change will create new demands on land and environmental resources–and could provide opportunities for novel crops and systems.”

Intense lobbying by food companies, the growing significance of climate change, recent international food crises and shortages and a major independent Royal Society report have all helped to give the government the authority to put GM back on the national agenda. The controversial technology was the focus of intense campaigns including destruction of GM crop trials by environmentalists in the 1990s, and last month came under renewed attack from academics and organic food campaigners at the Oxford Real Farming Conference.

Lord Smith will say: “We can already see wildlife following climate change – the mayfly is now found some 40 miles further north than before and warmer winters and wetter summers are thought to be a major factor in the rapid decline of pollinating insects with UK bee populations, in particular, falling by 10-15% over the last two years.

“The reliance on seasonal weather patterns means that farming will follow climate change too. My own personal view is that we probably need to be readier to explore GM options, coupled of course with proper environmental safeguards, in adapting to the changes that the climate will bring.”

The GM industry now involves 14 million farmers in 25 countries who are growing 134m hectares of GM crops around the world. This is a 7% increase compared with last year.

Indiana Prairie Farmer magazine wrote a recent story quoting a Franklin, Ind., precision farming consultant Greg Kneubuhler who says the next hot tool farmers want to invest in is row shut-offs for planters.

He says a savings of 5 percent can be achieved, which can deliver a payback in two years. And in some cases, with irregular-shaped fields, payback can be earned in one year.

TeeJet now offer two new solutions for ISOBUS sprayer control for owners of factory-installed virtual terminals, or for operators who require a complete system including a virtual terminal.

The TeeJet ISOBUS Sprayer System uses a John Deere, CASE IH or AGCO virtual terminal.  The kit includes the IC18 ISOBUS Sprayer Electronic Control Unit (ECU), BoomPilot automatic boom section control module, a switch box and all cable and connection to operate on Deere, CASE IH or AGCO virtual terminals. The IC18 Sprayer ECU has an intuitive interface with advanced features such as multiple rate selection, section status and task control for prescription applications.  The IC18 and BoomPilot can automatically control up to 9 sprayer sections.

TeeJet Technologies also offers a sprayer control solution that includes the components noted above plus the new Matrix 570VT interface. Matrix 570VT features a bright 5.7” touch screen suitable for daylight and nighttime viewing and can be used with other ISOBUS-compatible ECUs in addition to the IC18.

“We’re fully committed to the ISOBUS standard and want to help as many growers as possible experience the benefits of it,” said Jim Shone, Business Unit Manager at TeeJet Technologies. “Most growers don’t yet own a virtual terminal and will find our Matrix 570VT ISOBUS Sprayer System an affordable way to take full advantage of the ISOBUS platform. For the operators that do have a virtual terminal, our ISOBUS components are an economical way to leverage their current investment,” Shone continued.

TeeJet Technologies was among the first to sell ISOBUS compatible products in North America. ISOBUS job computers and controls have been in the field the last two growing seasons, and product line expansion is underway.

In 2001, farm machinery manufacturers agreed to implement a common standard for communication interfaces on tractors, implements and farm management systems. The standard is called ISO 11783 and is commonly referred to as ISOBUS.

The common standard enables products from different manufacturers to communicate and eliminates the need for separate terminals, displays and controls. Once ISOBUS is fully implemented, tractors will have a single virtual terminal in the cab.

A virtual terminal is the device that allows the operator to provide input information. An Electronic Control Unit (ECU), also known as a job computer, installed on the implement is where processing and control occurs.

Certified ISOBUS virtual terminals and ECUs will communicate and function on the same communication BUS, regardless of the manufacturer.

ISOBUS benefits:

• Operators can leverage their investment on factory installed terminals instead of having several controller consoles.
• Implements with certified ISOBUS ECUs give operators the flexibility to choose the best products for their applications without concerns about compatibility.
• Standardized plugs, cables and software simplify installation and connectivity and result in true “plug and play” technology.  Operators can operate multiple implements with any tractor in their fleet.
• Data from the ECU can be easily exported and analyzed on the farm computer.

Friday, I wrote about how Ag Leader listened to customers of their SMS Advanced software and built a Certified Training program to give participants deeper knowledge that helps their own business.

This weekend I spoke with Justin McCuiston, who helps customers of the farmer-owned cooperative Farm Service Inc., in northeast Arkansas with variable-rate fertilizer programs, yield mapping and other precision farming practices.

“We have five locations that cover about 8 counties in this rice and soybean area, where about half of our growers now use variable-rate prescriptions. In the past we used another software program, but switched to SMS Advanced which has turned out to be hands-down the best software I’ve ever dealt with in the 16 years I’ve been doing this,” McCuiston says.

“What truly makes it valuable is Ag Leader’s Certified Training program with the small class sizes and personalized training, which allows us to optimize the software capabilities to meet the services we offer to growers. We run 14 variable-rate fertilizer rigs that cover thousands of acres, and we couldn’t do that without the capabilities and batch processing features of SMS Advanced,” he says.

McCuiston says that once growers start with variable-rate fertilizer, they stick with it. “We re-pull soil samples every three years, which helps makes true believers out of them because they see soil improvements, fertilizer savings and improved profits.”

Superior precision farming software is crucial in order to help growers maximize in-field efficiencies. Ag Leader Technology not only delivers excellent SMS Basic training for growers, it now offers a three-day Certified Training course for its SMS Advanced software users who want to go beyond the one-day training.

SMS Advanced software is geared toward crop consultants, agronomists or other co-op personnel, precision ag managers, GIS mapping specialists and other service providers who provide precision farming services to growers. “We’ve been providing software and one-day general training since the late 1990s. But this past year we expanded to an in-depth three-day training course for advanced users,” says Michael Vos, SMS Sales Manager for Ag Leader.

“New and existing SMS Advanced software customers wanted an in-depth level of training, so we created a Certified Training program, which includes 15 to 22 CCA credits. We offer an excellent trainer to student ratio, as we normally have two trainers and 8 students, in our new state-of-the-art Ag Leader Academy computer lab,” he says.

The three days are tailored to exactly what the individuals want to learn. “We make lists of topics and details that are desired so users get the exact training to fit their business model. Some of the popular topics requested include: how to write equations for prescriptions, how to use aerial imagery and read it to make fertilizer use and crop scouting decisions, how to build a customer soil fertility booklet and creating soil management zones from aerial imagery and numerous years of yield data,” Vos says.

Every attendee receives a special certified manual with screen shot by screen shot steps for the software program. And within the book there are explanations why each tool is used, along with definitions and real world scenarios on how each tool is used.

“It’s definitely a complex tool, and when users see all the potential benefits of the software, they want to learn how to use it to the fullest extent,” he says.

We like to write weekly about how growers and how company technology makes precision agriculture pay. Part of making these tools pay almost always includes time savings—which isn’t always as black and white as input dollars saved.

Today I spoke with Hannibal, Mo., grower Mark Lehenbauer about his first decade with precision farming tools on their corn-soybean operation. Mark, who farms with his dad Ronald, has always been interested in the latest technology, and bought their first yield monitor in 2000, the year he graduated from college.

“At first, we tracked yield data, and it was a big learning curve on using it the way we should. The first efficiency we saw was yield loss due to weeds, so we switched to a two-pass application—which led to the purchase of a Hagie sprayer to cut our custom application costs.”

The biggest time saver came two years ago when they invested in auto steer. “Aside from the efficiencies we gained when spraying with Ag Leader’s DirectCommand AutoSwath boom control, we gained time savings and it reduced operator fatigue,” he says.

“Before auto steer, you would become just exhausted by mid-afternoon when spraying corn because you were focusing so intensely on the rows. With auto steer, it allows us to run an extra hour or two because all we do now is turn around, push the button and go.”

Lehenbauer says auto steer saves time during planting as well. “When you’re not exhausted at the end of the day, you can still run later and plant an extra 20 to 30 acres—which really adds up when you can shorten your planting window,” he says.

Analyzing data every winter has also turned into another time saver, too. “We use Ag Leader’s SMS software, and we look at numerous year’s data for hybrids and varieties in different tillage environments. It has truly helped us reduce tillage, saving time with more no-till. And the data has helped us realize the true value of no-till fields. Those fields have saved us time during harvest, because we can get into no-till fields quicker after a rain without leaving the ruts that often occur in our reduced tillage fields. Without ruts, we don’t have to do as much fall or spring tillage,” he says.

Lehenbauer also uses the data to write his own prescription maps, based off of university recommendations. “The data helps us find greater efficiencies on a field-by-field basis, comparing fuel usage and time spent in fields, even examining varieties than can take longer to harvest if there’s issues with green stem.

“It’s the little things we’ve done over the years that have added up to a lot of time and efficiency savings. You start figuring out acres by the hours you’ve saved and multiply that by your planting or harvest window—it really adds up to much greater efficiency,” Lehenbauer says.

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.

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.

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.

Sara Lee is taking a unique approach to market its 100% Natural line of EarthGrain brand bread. They are promoting wheat, known as Eco-Grain, grown by precision farming growers who use variable rate fertilizer driven by satellite imagery. And they’re calling it a movement, “Helping to preserve the earth, one field at a time.”

Horizon Milling (a joint venture between Cargill and CHS) plays the supply chain role of preserving the identity of the wheat from farmer’s fields to the bakery.

You can even meet a farmer who talks about growing Eco-Grain, as well as learn how to become an Eco-Grain grower.

Anti-agriculture activists, and I include foodies who view family farmers as ‘factory farms’ should take note how Sara Lee defines organic and sustainable farming. This is taken from the EarthGrains Website…

While Eco-Grain wheat is not organically grown, the more sustainable farming methods used to grow it have some advantages over organic farming.

• Organic farming requires about twice the acreage to produce the same amount of food, resulting in the destruction of undeveloped land.
• Consumers pay a premium for organic grain, since it costs more to grow it.

Sustainable agriculture practices use less fertilizer, conserve land, help protect ground and surface water, and result in a high-yield, lower-cost crop.

Wow, a voice of reason. This is truly agriculture’s view of sustainable farming, and organic is not sustainable.

And here are location where you can buy these breads.
