A review on the dynamics of soil microbial biomass in forest ecosystems
Soil microbial biomass is the most active component of soil organic carbon that regulates biogeo-chemical processes in terrestrial ecosystems. A lot of studies reported that there were significant seasonal fluctuations of microbial biomass in forest soils. We reviewed on the soil microbial biomass dynamic patterns and their control factors in forest soils from lots of references. There were mainly three patterns of soil microbial biomass dynamics: more in summer and little in winter,more in winter and little in summer,and alternately wet-dry season cycle,which may correlated to soil temperature, soil moisture, drying and rewetting cycle and plant growing rhythm, etc. Further studies should be focused on the factors and mechanisms regulating seasonal dynamics of forest soil microbial biomass. Moreover, we also should concentrate our research on the couple of seasonal dynamics of soil microbial biomass N,P and soil microbial biomass C.
