ENZYMATIC ACTIVITY OF SOD-PODZOLIC SOILS UNDER THE CONDITIONS OF EXPOSURE TO EMISSIONS OF A BUILDING MATERIALS MANUFACTURING ENTERPRISE

The article presents the results of studies influence a large industrial enterprise on soil cover. It is shown that for production building materials significantly affects agrochemical and biological indicators soils. This manifested primarily in change acidity soddy-podzolic sandy loamy soils shift pHKCl index towards alkalization. has been established with slightly alkaline (pHKCl from 7.06 to 7.42) environmental conditions 7.55 8.09) prevail this zone. features course enzymatic processes subject gas dust pollution have established. levels activity redox (catalase, dehydrogenase) hydrolytic (invertase, urease) enzymes were determined distance gradient source along directions air mass propagation. There decrease these forest agricultural lands as one approaches pollution. within radius up 2 km pollution, are characterized very poor terms enrichment studied enzymes. According correlation analysis, there reaction environment statistically significant negative relationship.
