Abstract
In agricultural soils, the microbial biomass and activity act as a source-sink for labile nutrients. Practices which alter the size of the biomass or its rate of N and C turnover can affect crop growth. Fifteen soil samples were analyzed for microbial biomass, mineralizable C and N contents. These soils were covered with different crops such as fruit, cereal, vegetable, industry crop and pasture for long years. Microbial biomass ranged from 57,39 to 105,30 mg C 100 g−1 and varied significantly with different cropping systems. The highest microbial biomass values were determined in soils which were covered by vegetables. Soils which were under cereal had the lowest microbial biomass, mineralizable C, and N. Inorganic fertilization and minimum tillage increased mineralizable C and N contents.
