The study of the microbial biome, the study of biodiversity and the spatial-functional structure of the microbial complex is an important element in assessing the impact of various agro-technical measures on soils. The aim of the research is to reveal the changes in the abundance of different groups of organisms of chernozem regraded under various fertilizer systems. The results of the influence of intensive, organic and low-cost fertilizer systems on the number of humectant, pedotrophic, ammonifying and amylolitic groups of microorganisms, as well as micromycetes, are given in the article. It was found that the greatest number of microorganisms decomposing organic forms of nitrogen was obtained under the organic system - 3.1 million CFU per 1 g a. from. g, 2.2 million CFU per 1 g of a. from. in an intensive system.
