Evaluation of the total biomass has been done for the first time in four zonal soil types. A certain correlation has been found between the biomass pool in soils and potential respiration intensity. The microbial biomass is composed mainly the biomass of eucariots (88-99 %), while the biomass of procariots ranges within 1 % (chestnut soil) and 12 % (grey forest soil). In terms of their microbial biomass the soils under study may be arranged in a following sequence: grey forest soil (5.7 t/ha) sod-podzolic (14 t/ha) chernozem (15 t/ha) chestnut soil (32 t/ha). The biomass of microbial coenoses is rather regularly distributed in the profile, not being concentrated in the upper soil horizons, as it was assumed earlier
