The article examines the activity of enzymes in black soil and gray soil zones and the characteristics of specific enzymes. Also, unfavorable conditions for the strong functioning of substances with biological activity (air temperature, soil pH indicator, influence of humidity. In addition, the amount of humus substances in gray soils is low, that is, in the upper layer, it is only 1-1.5% In this zone, the activity of enzymes, particularly peroxidase, was found to be 3-3.5mg/g, and the activity of polyphenoloxidase was 0.50-070mg/g.
