During 1976 through 1978, 10N treatments (combinations of N application times and rates) were used in a corn study. Those treatments created different levels of soil NO 3 − −N content that were well-suited to a study of the influence of residual NO 3 − −N and applied N on soybean yield. In April 1979 we applied ammonium nitrate at rates of 0, 75, or 150 kg(More)
