Cover Crops Earn Another N Laurel

A variety of conservation practices are available to help farmers reduce the amount of nitrogen (N) leaving their fields and travelling downstream, according to Laura Christianson, department of crop sciences at the University of Illinois. She says the practices are grouped into three primary categories: Management practices that can be done in-field, structural practices that can be built at the edge of a field and land use changes. The university research found the biggest cost efficiency in dollars per pound of nitrogen saved is when cover crops are used on all non-tiled acres.  —Sonja Begemann
