Abstract:

A laboratory aerobic incubation test was conducted under constant temperature and moisture to study the mineralization process of organic nitrogen in organic material with different C/N ratio and the effect of organic carbon added on it. The results showed that the mineralization rate of organic nitrogen in soil and soybean mixture was the fastest,reaching the maximum on the 30th day,the mineralization rate of organic nitrogen in soil and corn stalk mixture was the slowest,the addition of organic carbon evidently inhibited the mineralization process of organic nitrogen. While,this inhibition was temporarythe ultimate development trend was the mineralization of organic nitrogen.

Key words: carbon-nitrogen ratio, organic carbon subst rate, mineralization process of organic nitrogen
