ENZYMATIC ACTIVITY OF THE RHIZOSPHERE OF GRAIN CROPS UNDER THE CONDITIONS OF THE SOUTHERN FOREST-STEPPE OF WESTERN SIBERIA

The research was carried out on spring soft wheat in field experiments of the Omsk Agricultural Research Center in the southern forest-steppe of Western Siberia in order to determine the effect of the use of biologics of associative diazotrophs on the biological properties of the rhizosphere of spring soft wheat. It was found that the basal microflora of soft wheat reacted ambiguously to inoculation with biological preparations and depended both on the genotypic characteristics of the varieties and on the preparation used. The activity of hydrolytic enzymes in most variants of the experiment tended to increase compared to the control (up to 17%), however, the activity of the redox enzyme catalase decreased as a result of applied agricultural method within the experimental error (up to 4%).
