QUANTITATIVE CHANGES IN SOIL MICROORGANISMS OF GRAY FOREST SOIL WHENUSING BIOLOGICAL PREPARATIONS

Abstract

With an increase in the level of intensification of agriculture, the beneficial microbiota is sometimes replaced by a pathogenic one. Biological preparations, which include specially selected soil microorganisms, come to the rescue. The purpose of the study is to study the effect of the use of microbiological preparations Sternifag and Biocomposite – correct on the indicators of biological activity of gray forest soil. The article presents the results of a study of the number of microorganisms in the use of microbiological preparations (destructors). A comparison is made on the change in the number of bacteria and fungi during the cultivation of spring wheat against the background of various tillage and the use of ammonium nitrate. The presence and abundance of microorganisms were determined on media MPA, KAA, Chapek, Ashby
