Enzymatic activity of black soils in Elbrus zonation variant at Kabardino-Balkaria

It is defined the enzymatic activity (invertase, phosphotase, catalase) of black soils at a steppe zone and belt of meadow steppes of Elbrus zonation variant in Kabardino-Balkaria. The studied soils show average enzymatic activity. The maximum activity of enzymes, the maintenance of humus and hygroscopic hu-midity isnoted in ordinary and typical black soils. The interfaced changes of enzymes activity among themselves, with the maintenance of humus and hygroscopic humidity are revealed.
