摘要

U.S. corn yield (Zea mays L.) and fertilizer N consumption data are briefly reviewed, and selected Land Grant university research-based recommended N rates for corn in the U.S. are compared with public data on actual N rates used by farmers in leading corn-producing states to determine if farmers may currently be over-applying N. Contrary to popular belief, U.S. corn farmers in leading corn-producing states do not appear to be applying N at rates in excess of profitmaximizing university recommendations
