摘要：
Meadow chernozemic soil was studied in an idle land-shelterbelt-cropland system. It was found that the long-term agricultural use of chernozems leads to a decrease in the total nitrogen content and to changes in the soil microbial community. The portion of phytopathogenic Fusarium, Aspergillus ustus, Penicillium daleae, and Penicillium rubrum microorganisms in the complex of soil fungi increases, and the phytosanitary state of the soil worsens. The use of biotests made it possible to estimate the role of particular microorganisms in the soil phytotoxicity.
