Results show that microbial biomass carbon and microbial biomass nitrogen in fertilized soil peak in the first several days, and then decline. Incubating both sweet maize straw and white clover have the highest yield, maxima of 529.57 mgkg^(-1) and 75.50 mgkg^(-1) respectively. They also release respired CO2 the most among all treated soils. The best mineral nitrogen release is in white clover incubating, with a maximum of 29.81 mgkg^(-1) under a 26-day culture, and then keeping 1.60 times the control and reaching 2.48 times at 80-day culture. Sweet maize incubating has the least mineral nitrogen release. It is 13%~53% of the control under a 26-day culture, with a maximum of 7.51 mg kg^(-1). Soil nitrogen mineralization is insignificant under sweet maize incubating with urea in short-term.
