THE SOIL MICROBIAL COENOSIS STATE UNDER VARIOUS CROPS IN CASE OF INTRODUCING THE MIXTURE OF SILICON-CONTAINING MINERALS

Abstract

In the conditions of stationary experiment the features of the formation of microbial coenosis in the rhizosphere of sugar beet, soybean and corn plants were studied in case of introducing silicon-containing mixtures into the soil. It was shown that the number of representatives of separate eco-trophic groups of microorganisms varies depending on the culture and introduced mixture. Soil microbial communities from under soybean and corn were characterized by the biggest changes, especially in case of mineralized sapropel introduction. Positive effect on sugar beet rhizospheric soil microbiota was made by mixtures: high-bog peat + siliconcontaining minerals and potassium silicate + silicon-containing minerals + sapropel. The processes of soil organic matter mineralization were quite balanced.
