Abstract

A study of organic, integrated and inorganic plant nutrient management systems was conducted to determine the effect of management practices on soil microbiological properties after 10 years of continuous application. The rate of C mineralization and potentially mineralizable nitrogen were 6.8 and 41.5 mg/kg soil, respectively. Arginine ammonification and nitrification activities were 0.88 μg NH4+-N/g soil/h and 56.0 μg NO3--N/g/day, respectively. Microbial biomass C, N and P were 320, 40 and 12 mg/kg soil, respectively. Alkaline phosphatase, urease and cellulase activities were highest with application of VC@15t/ha.
