Agro-ecological assessment of the condition of arable soils of the CCR

Abstract

Abstract The data sources for the study were the results of a continuous agrochemical (for 3 cycles) and soil erosion survey of soils, as well as official statistical data. The study period was characterized by an increase in the content of organic matter in the soil by 0.35%, alkaline hydrolyzable nitrogen by 20 mg/kg, an increase in pH acidity degree by 0.15 pH units, a reduction in the amount of medium acidic soils by 16.4%. It was found that on poorly eroded soils, the content of organic matter decreases by 0.4%, on medium eroded soils - by 1.7%. Doses of organic fertilizers increased by 3.0%, mineral fertilizers - by 7.8%. The winter wheat yield increased by 13.3%, spring barley - by 20.7, grain maize - by 4.7, sunflower - by 13.6, sugar beet - by 12.6, and soybeans - by 18.4%.
