| Abstract: | The factors affecting soil microbial biomass nitrogen and the relationship between soil microbial biomass nitrogen and mineralizable nitrogen are reviewed. The effects of soil organic matter, organic material, nitrogen fertilizer, crop root, soil temperature and moisture on soil microbial biomass nitrogen and the relevant study progresses are emphatically discussed. At the same time, the study results of the relationship between soil microbial biomass nitrogen and mineralizable nitrogen are evaluated in this paper. |
