Dry conditions may have a negative impact on nitrogen applications in some areas of the country, according to experts at South Dakota State University.

According to SDSU Extension Soils Specialist Ron Gelderman, while surface application of nitrogen fertilizer in late fall and early spring is a typical practice in South Dakota, dry soils this season may be putting that nitrogen in jeopardy.

“With the weather being so very dry, warm and windy, and if we didn’t get that third to a half an inch of precipitation on that urea to move it into the soil and protect it, fields could have experienced some significant loss,” Gelderman said in a radio interview.

Gelderman says winter wheat, which is at, or close to jointing, will need a nitrogen application soon if significant loss of the applied urea occurred. Producers have more time before they need to test spring- planted grains and row crops. Gelderman says growers may want to use a urease inhibitor with future surface urea applications to increase the odds of getting some moisture.

California organic produce grower Phil McGrath is monitoring his fields from his smartphone to save water, time and money thanks to ClimateMinder technology.

McGrath, owner of McGrath Family Farms commented, “On our ranch there are several different soil types. One cropping program does not fit all. With ClimateMinder you get very accurate information about the soil moisture content on any block. I’m irrigating less overall. It’s saving me water, time, and money.”

ClimateMinder’s CEO Bulut Ersavas explained, “By monitoring and controlling to measured conditions, ClimateMinder can alert growers in real-time to conditions that threaten their crops, such as extremes in temperature or moisture, and the need to take corrective action.”

ClimateMinder’s monitoring, management and control platform is provided as an internet-based software-as-a-service (SaaS). The system gathers data using an intelligent, fail-safe mesh network of wireless sensors and controllers that can be installed quickly and cost-effectively throughout an entire field, with a recommended density of one station per 20-40 acres.

Ersavas also added, “Our system ensures that growers have the information to optimize the management of their water, nutrient and chemical supplies, lowering costs and increasing yield and profits. And by maintaining this information in ClimateMinder’s professional database, growers are able to better plan, budget, and organize their crops from season to season.

“We work with our growers from installation to training and on-site support to make sure they utilize the system to the fullest extent. We are also constantly innovating and improving the features of the system with the feedback from our clients.”

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.

Yesterday, I provided my list of the “Best of Precision Pays 2009″ for  January through June. Today’s list of stories runs from July through December. And tomorrow, look for the top product-related stories of the year.

I hope you continue to find value in the information provided. And, as always, we appreciate any and all comments from our readers.

Enjoy. And have a fun, safe and happy New Year’s Eve tonight.

Popular Science magazine did a nice job providing readers with a glimpse into the precision agriculture research that is needed to grow twice as much food by 2050. The writer talked about how this challenge is everyone’s problem, but scientists are hard at work fomenting a second green revolution.

Here are the research projects that the magazine chose:
1. Sahara Forest Project — Greenhouses using seawater and solar power to grow cash crops in the desert.
2. Soil sensors — Research at Iowa State University into wireless soil sensors that may help farmers use water, fertilizer and other inputs more efficiently.
3. Improved rice — Researchers hope to turn this staple crop into a super rice that grows faster in warmer and drier climates by transforming its photosynthesis process.
4. Replace fertilizer — Michigan State researchers attempt to replace/reduce commercial fertilizer use with microbes. They are currently field testing microbial cocktails (Bio-Soil Enhancers) that can simultaneously reduce the need for phosphorous and nitrogen, protect plants against pathogens and boost yields in virtually any type of crop.
5. HarvestChoice — The Gates Foundation is funding data compilation of Africa’s agricultural systems and land use to increase yields to feed the growing continent.
6. Satellite soil moisture — NASA and USDA are working to monitor soil moisture levels around the globe to hopefully improve crop forecasting.
7. Robot labor — The challenge of American specialty crop growers finding human labor is increasing difficult. Current research using robots with a variety of sensors will help machines scan for fungus, growth rate, soil moisture, humidity, light levels and more. But cost of such technology is the current challenge.
8. Rebuilding soil — Scientists hope to turn waste into a charcoal that, when applied to degraded unproductive soil, will attract microorganisms to help plants access nutrients, hold more water and lock in carbon. Companies are working on portable machines to produce biochar on-site.
9. Make supercrops — Research is bioenginering the African staple crop cassava root to turn it into the PowerBar of the vegetable world. They’re attempting to increase protein, add vitamins, increase shelf life, add virus resistance and eliminate cyanide-producing toxins in the root.

At this week’s InfoAg 2009 precision farming conference, National Corn Grower Association yield champion David Hula of Renwood Farms in eastern Virginia gave a presentation on technology and productivity.

As a seed producer, he likes to keep his customers informed on proper planting dates. One technology he uses to do this is Skybit.com. Hula says this virtual weather station accurately tracks soil temperature, which he ground-truthed for accuracy, so he can alert his customers to fire up the planters when the soil hits the right temperature combined with an upcoming warming trend. He also likes the disease modeling capabilities to time fungicide application. And he can include this weather data as an overlay to his yield maps.
