Influence of Cropping Intensity and Nitrogen Fertilizer Rates on In Situ Nitrogen Mineralization

Cycling of N through an agroecosystem can be managed more effectively if effects of N management and cropping sequence on soil N microbial processes are understood. Effects of cropping intensity and N fertilizer rate on net soil N mineralization were studied as well as their correlation with precipitation, air temperature and soil water content. Net soil N mineralization was measured by incubating undisturbed soil cores (15‐cm depth) containing...
