FORMATION OF MICROBIAL COMPLEX OF TYPICAL CHERNOZEM IN AGROCENOSIS OF WINTER WHEAT AT DIFFERENT AGRARIAN SYSTEMS

Abstract

Analysis of the formation of microbial complex
of typical chernozem in agrocenosis of winter wheat
has been analyzed. The level of differentiation of
number of the basic physiological and taxonomic
groups of microbes has been identified. Features of
structure formation, the qualitative composition and
diversity of bacterial complex at different agrarian
systems and tillage of soil have been shown. It has
been established that the systematic application of
organic fertilizers allows to be optimized
microbiological processes and contributes to
increase of species diversity with a uniform
distribution of the dominant forms of
microorganisms.
