The assessment of a degree of biological degradation of drained peat soils in the Brest Poles'e by level of total biomass soil microorganisms is given. The powerful peat soil as characterized by a maximum biomass of bacteria, actinomyces and fungi: (724,20 +-48,40)x10-5g/g. Total biomass of microorganisms in the degrading-peat and peat-mineral soil having a medium degree of mineralization was less by 5,43 times (p0,05) in comparison with the biomass in the powerful peat soil. This has allowed to evaluate the first soil by biological criterion as degraded one having the degree of degradation of 1 (in the 0-4 scale). The remaining varieties of the investigated soils (humus-peat, humus-gley, humus-peat-gley and mean-power peat) had degradaton degree by biological criterion equal zero
