Abstract

Soil temperature has been the primary criterion for evaluating risks associated with losses of fall-applied nitrogen (N). The basic idea is that ammonium is not converted to nitrate in cold soils, so withholding applications until soils are cold reduces the risk of N losses by leaching and denitrification when soils have excess water in the spring. Recent studies indicate that soil pH also deserves attention.
