Gonchar N. Ecological role of enzymes in artificial edaphotopes of Nikopol basin of manganese ores.

The objects are edaphotopes of technogenic landscapes of Nikopol basin of manganese ores. The aim is to define the ecological role of enzymes of soils and their influence on properties of artificial biogeocenoses in conditions of Nikopol basin of manganese ores. The methods are laboratory-chemical, ecobiochemical, mathematical-statistical. The physical and chemical and ecological features of the used rocks which influence on passage of biochemical processes in their thickness are investigated. Change of a level of fermentative activity in meter thickness of artificial edaphotopes for certain historical time is demonstrated. It is established, that the biotic and abiotic factors influence on formation of enzymatic potential. The features of accumulation of enzymatic activity at formation of young soils in conditions of technogenic landscapes of Steppe of Prydniprovya are revealed. The orientation of biochemical processes in thickness of artificial edaphotopes descends the same as in zonal chernozem: reactions of hydrolysis of complex organic compounds dominate, and process of synthesis of humus substances is carried out slowly. The gradation of biogenous degrees of edaphotopes in accordance with the activity of enzymes is advanced. The further development an opportunity of use of the level of enrichment of edaphotopes with enzymes as diagnostic test for the objective control over a state of arable thickness of the recultivated lands has been received. Application spheres are recultivation, monitoring, training courses.
