FEATURES OF MICROBIAL SUCCESSIONS INTHE SEASONAL AND LONG-TERM DYNAMICS IN CHERNOZEMS OF THE RESERVED MEADOW STEPPE AND BLACK FALLOW
The results of the study of microbial communities in the soil chernozem long-term black fallow and reserve steppe. The number of microorganisms, defined by surface seeding on solid nutrient media, showed no statistically significant differences in Central Chernozem reserve soil. The coefficient of mineralization (by E.N. Mishustin) testified to a balance of mineralization processes of autochthonous and allochthonous organic matter. The use of GC-MS allowed to reconstruct the samples investigated species composition of soil microbial community, the dominant genera and species of microorganisms. It was shown that the dominant in soil microbial community in the chernozem reserve steppe and of long-term black fallow was consortium of anaerobic microorganisms belonging to the phylum Firmicutes.
