| Popis: | Enzymes in the soil are closely related to the physical, chemical and biological characteristics of the soil and regulate the formation of soil fertility, organic matter, nutrient mineralization and cycling in nature. Soil contains phosphatase, urease, dehydrogenase, catalase, peroxidase, saccharase, protease, amylase, β-glucosidase, arylsulphatase and other enzymes. The purpose of the given work was estimation of catalase protease and urease activity on three different types of soil as high mountained steppe and dry steppe roughly humusified soil; mealy brown carbonated soil and mountain meadow forest soil which are common in the mountain and steppe regions of our country in correlation with soil depth and anthropogenic impacts. In all soil samples the highest enzymatic activities were detected in the depth of 0-15 cm from the soil surface. For all soil samples the enzymes activities decreased more rapidly with increasing soil depth affected to anthropogenic impacts in comparison with samples not exposed to human impacts. |
