Technical Abstract: Irrigation-induced erosion has decreased the average crop production potential of irrigated lands in southern Idaho more than 25%. Recent research has provided new technology to stop this process. New technology includes growing corn and/or cereal the first two seasons following alfalfa and then using reduced tillage practices for the remainder of the crop rotation cycle, applying low concentrations of polymers in the irrigation water during the early part of the irrigation season and applying cheese whey and straw to irrigation furrows to reduce erosion. Farmers are encouraged to farm smarter instead of harder. Following these practices can essentially eliminate irrigation induced erosion, reduce the potential for nitrate leaching, and increase net farmer income $500 to $100 per acre each year.
