Abstract
Pyrazosulfuron-ethyl was one of the most popular herbicide used in paddy field in north east of China. Effect of Pyrazosulfuron-ethyl in farming dosage on microbiological activity related with N transformation was studied through indoor incubation experiment in this paper. The results showed that soil urease was inhibited within 7~30d. Soil nitrification and microbial biomass N were all inhibited during the first 20 incubation days. The relationship among the urease activity, nitrification and biomass N was remarkable.
