摘要:

A direct extraction method to estimate both soil microbial C and N, using a single extractant and chemical digestion stage was evaluated. Soils were fumigated overnight with EtOH‐free CHCl3, the CHCl3removed, and the soils extracted in 0.5MK2SO4. The flush of microbial C, measured as organic C, and microbial N, measured as NH4‐N, were estimated after acid‐dichromate treatment of the soil extract.
