The article deals with the ecological role of glucosidase for fertility mountain-forest black-brown soils of Kukart watershed. The results of the relationship glucosidase enzymes with organic matter mountain-forest of black-brown soil… A study of the enzyme glucosidase allows predicting the studies of soil microbial activity. β-glucosidase is the dominant enzyme in the soil. This enzyme plays an important role in the mountain-forest of black-brown soils, because it is involved in as a catalyst for the hydrolysis and biodegradation of various β-glucosides present in the decomposition of plant residues in the ecosystem. This is important for the supply of digestible nutrients forms of vegetative plants and addition of new reserves of humus substrates of organic substances. High enzyme activity of soil marked by β-glucosidase and ranges from 19.3 to 1137, 5 mg of p-nitrophenol kg-1 soil h-1c brown soil, from 11.1 to 1235.9 mg of p-nitrophenol kg-1 soil h -1in dark brown soil. Of glucosidase enzymes, β-glucosidase dominates β-glucosaminidase. Enzyme β-glucosidase plays an important role in the carbon cycle (C), involved in (degradation) splitting cellulose, which is important in the cleavage of silvicultural residues. Glucosidase activity of brown soil depends on the content of humus, the annual forest growth litter and organic nitrogen, which are the initial substrate for the enzyme.
