Abstract

Research during the past decade has provided evidence that most corn producers could substantially reduce rates of N fertilization if they delayed application of nitrogen (N) until after plants had emerged from the soil. Additional evidence was collected in precision farming trials in 2001. The trials were conducted in 13 fields planted to corn following soybean. None of the fields had received recent application of animal manure. None had received more than 30 lb N/acre since harvest of the previous crop.
