Microbiological communities of bacteria and plants (microbocenoses)

Montina Irina Mikhailovna

The article provides an overview of the role of bacteria in the creation of soil microbiological communities. It is shown that bacteria form a special complex with plants, participate in the circulation of various substances, and ensure a stable state of the ecosystem. The biomass of bacteria differs in different types of soils. The largest biomass of microorganisms is characteristic of chestnut soils – 32 t / ha, almost half as many microorganisms are contained in chernozems (15 t/ ha), and sod-podzolic soils (14 t/ha), the smallest biomass of microorganisms in gray forest soils – 5.7 t/ ha. Different types of soils are characterized by different species composition of soil microorganisms. Soil microbial communities react differently to the application of various fertilizers and pesticides. The types of bacteria capable of destroying herbicides are described.
