Effect of herbicide on microbial activity in paddy soil

Under submerged incubation with different herbicides (Quinclorac, Pyrazosulfuron) dynamics of soil microbial activity and biochemical characteristic in a waterlogged paddy soil were studied. Show soil basal respiration was significantly enhanced during the training besides at first day. soil microbial biomass carbon and nitrogen were significantly control, however, soil microbial phosphorus was enhanced.
