NTech-nically Speaking A look at one company’s efforts to maximize food production to save the world and why some oppose it. David Crossley BAE 4213
Overview • Background • Nitrogen Concerns • NTech & OSU • Farmer Feedback • Conclusions and the future…
Problem Statement • Nitrogen being applied ineffciently • End result is a higher cost for already struggling farmers • Environmental impacts
Principal Nitrogen Losses Denitrification - lack of oxygen for bacteria in soil Surface Volatilization - lack of moisture, no contact with soil Leaching - more water than the soil can hold Anhydrous ammonia converts to N the slowest.
Environmental Impacts Health problems related to high nitrate levels, especially in rural and well water supplies.
NTech • Patchen Technologies began in 1992 (James Beck) • Sold to Deere & Co. in 1996 • Purchased in 1998 by Rainbow Ag Services (Mayfield) • Patent review found similar design technologies in Australia and OSU • Technology originated from weed control
Variable Rate Nitrogen App. • RT-500 model • Sensors measuring plant NDVI • Nitrogen applied based on NDVI results • Zone area < 6 m2
Farmer Feedback • How many acres? • Do you apply N pre-plant & how? • Do you top-dress in the spring? • Who performs the top-dress application? • Would you consider such a system for your own applicator? • Would you support a COOP owned applicator with such a system?
More Farmer Feedback • Majority of farmers say that cost is the main issue • Supportive of COOP sponsored program • Lack of exposure • More demo machines need to be implemented
David’s 2 Cents & The Future • Age of Impatience • Age of Old Age • Lack of Knowledge • RT-200 • Other applications
