ABSTRACT With current agricultural practices the amounts of fertilizer N applied are frequently more than the amounts removed by the crop. Excessive N application may result in short‐term accumulation of nitrate nitrogen (NO3–N) in soil, which can easily be leached from the root zone and into the gr...
