Soil enzymes play a major environmental function by participating in biochemical processes related to the conversion of substances and energy into soil. The purpose of the research is to study the biological processes occurring in the soil under the influence of different farming systems. The activity of the following soil enzymes was studied: catalase, urease, dehydrogenase, protease and cellulase. The largest changes in the activity of soil enzymes were observed in the layer of 0-10 cm. Organic farming enhances the enzymatic activity at the level at which is found in uncultivated soil (fallow). The use of green manure increases the activity of most soil enzymes. The intensive farming system is characterized by a much lower enzyme activity in the 0-10 cm layer, as well as an increase enzyme activity in in the 20- 30 cm layer, which is related to the soil tillage features (layer turnover). Hence the enzymatic activity directly depends on the farming system.
