Abstract: The effects of clear and selective cuttings on soil microorganism, soil enzyme activity and nitrogen metabolisms were investigated. A 30% intensity of selective cutting made an increase of the activities of soil microorganisms which favoured the biological cycling of nutrient elements through the decomposition of litterfall. Under conditions of clear cutting and overcutting, as a result of the stimulated decemposition and nitrification, nutrient losses to streams, particularly in the form of nitrate may lead.
