Abstract
Data from an experiment conducted on a silt loam soil in Ohio, USA, have demonstrated that the largest maize grain yields were obtained with 160 lb N/acre and soil K levels of 232 lb/acre. In the presence of K the large N uptake by plants decreased the soil N content after harvest and reduced the risk of groundwater contamination. Economic aspects of these results are considered.
