Anthropogenic soil formation fundamentally differs from natural soil formation in accelerated rates of transformation of the organic and mineral part of soils. Therefore, the farming system must be soil-protective, energy-saving and ecological to ensure the ability of soils to perform their main biosphere functions. To assess the state of ecosystems, biomonitoring is more informative than recording the physical and chemical parameters of the soil state. The purpose of the research is to study changes in number of soil microorganisms that occur in the soil under the influence of various farming systems. The number of representatives of various functional groups of microorganisms was studied on agarized nutrient medium. Agrochernozems are characterized by a decrease in the number of micromycetes and, conversely, an increase in the number of actinomycetes and amylolytic microbiota. The intensive farming system leads to a decrease in the number of microorganisms in the 0-10 cm soil layer and an increase in the 20-30 cm soil layer. [ABSTRACT FROM AUTHOR] |
