Popis:	To indicate factors determining the location of microorganisms in the soil structure, moist and dried-remoistened samples of a silty-loam soil were separated into particle-size fractions after gentle dispersion (shaking in water for 16 h). Microbial biomass C and total organic C and N contents of soil fractions were measured. The presence of microaggregates in each size fraction was determined by texture analysis of fractions. More than 50% of the microbial biomass C content of the total soil and 37% of the soil organic C content were associated with the aggregated clay (20-2 μm) and the clay-size (
