Natural and anthropogenic transformation of meadow-brown heavy loamy soil and its impact on the productivity of agrocenoses

Abstract

Based on the analysis of the results obtained, the research established that the criteria for the natural transformation of soils both in the ecosystem and in the agrocenosis depend on climatic (hydrothermal) conditions, the criteria for anthropogenic transformation include the food regime of soils and the productivity of agrocenosis. The yield of crops without the introduction of mineral fertilizers is determined by the reserves of humus. When applying mineral fertilizers, their content in the soil affected the crop to a greater extent than the humus content.
