MICROBIOLOGICAL AND GEOECOLOGICAL PARAMETERS CHANGE OF SOD-PODZOLIC SOIL STABILITY IN TERMS OF USE OF HIGHSILICON STONE
The article presents the influence of different silicon-containing naturally occurring materials on microbiological and geoecological stability of sod-podzolic soil in the Nizhniy Novgorod Region. Rise of stability of nitrogen-containing organic substance transformation processes and optimization of oligocarbofile part of the soil microbic pool under the influence of white peats and bentonite clay at a dose of 3 and 6 t/ha is shown in the article. Rise of the soil geoecological stability in the form of substantial reduction of heavy metals flexible compounds content and its concentration index, stipulated by the effect of silicon-containing stone, is revealed in the article.
