The maximum number of proteolytic microorganisms and the highest proteinase activity were detected in the humus horizon. These indicators of soil biological productivity declined with depth. Proteolytic microorganisms were most numerous in mid-vegetation and least numerous in the second half of vegetation in both horizons, numerical values being lower in the horizon of 20-40 cm. Proteinase activity proved the highest in mid-vegetation and the lowest in the second half of vegetation in the horizon of 0-20 cm. In the horizon of 20-40 cm, a constant decrease in proteinase activity was noticed all vegetation long.
