Influence of pasturable load on the enzymatic activity of Northwest Caucasus forest soils

Change of indicators of enzymes activity and the maintenance of humus in soils of pastures under intensive loading is investigated. Pasturable loading leads to decrease in studied indicators. The maintenance of humus under pasture is 20-48% lower, activity of catalase for 35-48%; invertase for 49-50%; dehydrogenase - for 20-50%. The maximum changes fall on the top horizon which is exposed to direct influence. With depth the distinction in the studied indicators become less considerable.
