Biodiagnostics of chernozem degradation at development the hydromorphism processes (in model experiment)

Results of laboratory experiment on modeling the degradation processes against remoistening and to their influence on ecological and biological properties of chernozem are presented. The comparative assessment of chernozem ordinary biological activity at gleyisation, acidification, salinization and solodization on the basis of determination the enzymatic activity and state of microbic communities is carried out. As a result of some model experiments it has been revealed that process of gleyisation stimulates the total number of bacteria and suppresses micellar organisms. Significantly activity of oxidoreductase goes down and the hydrolase increases activity. The main tendency is connected with the expressed inhibition of enzymatic activity when modeling acidification, salinization and solodization. High sensitivity of separate groups of microorganisms to various influences is noted. Development the degradation processes when strengthening a hydromorphism causes radical change of ecological and biological properties of chernozem.
