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

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