摘要
We investigated the effects of converting forest to savanna and plough land on the microbial biomass in tropical soils of India. Conversion of the forest led to a significant reduction in soil organic C (40-46%), total N (47-53%), and microbial biomass C (52-58%) in the savanna and the plough land. Among forest, savanna, and plough land, basal soil respiration was maximum in the forest, but the microbial metabolic quotient (qCO2 was estimated to be at a minimum in the forest and at a maximum in the plough land.
