Contents of soil microbial biomass nitrogen and its mineralized characteristics and relationships with nitrogen supplying ability of soils
土壤微生物量氮含量、矿化特性及其供氮作用

As soil microorganisms decompose the organic matter,they also assimilate a portion of the nutri- ent in soils to build their body.The nutrients in soil microbial biomass are mineralized from the dead mi- croorganisms.Therefore,soil microbial biomass is considered as a source and sink for nutrients,and is an active pool of organic matter in soils.Because of its important role in various ecological systems,nitrogen contained in soil microbial biomass(i.e.,SMBN) has got much attention in recent years.This ...
