Summary
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 N/ha to three subplots formed from each of the whole plots (previous N treatment plots). With N fertilization in 1979, seed yield increased where the residual NO −3 −N amount was less than 190 kg/ha but decreased where the residual amount was greater than 190 kg/ha. As the NO −3 −N content in the soil increased by 1 kg/ha, the soybean yield increase due to N fertilization in 1979 decreased by approximately 4 kg/ha.
