Soil microbial biomass in forest soils with different silvicultural practices were measured by fumigation extraction method. A secondary forest of Pinus densiflora mixed with Quercus serrata has been cut on March 1994 and half of the clear-cut area has been slash-burned on August 1994. Soil organic layer and surface soil from 0cm to 5cm in depth were collected on April 1995 and July 1995. Average soil microbial biomass was highest at the secondary forest and lowest at slash-burned both for the organic layer and the surface soil. In most of the study plots, the average soil microbial biomass were higher on the ridge than the bottom of the slope and, also higher on July than on April. Detrimental effect of clear-cutting and slash-burning on soil microbial biomass were confirmed one year after those event.
