Abstract
To characterize the effect of heavy metal Cd on soil microbial activity, urease activity was analyzed based on the enzymatic products of ammonia. . The results showed Cd concentrations had little effect on the urease activity and the incubation time had strong effect on the activity of urease activity with the incubation time. Cd had a significant effect on urease activity during the incubation phase. Urease activity was significantly higher than that of without addition of Cd in soil. When the activation effect of Cd was studied, there is a threshold of Cd among the concentrations of Cd. The threshold can promote the urease activity increased and be conducive to microbial decomposition of urea. Once the threshold is exceeded, the decomposition efficiency of urea will reduce the effect, absorption and utilization of microbial.
