Вплив системи удобрення чорнозему типового на петворення азоту у порівнянні з чорноземом постагрогенного використання

Abstract

In the field under the fallow land, soil aeration becomes less and all processes of decomposition of plant residues slow down. The activity of microorganisms that decompose organic compounds in the fallow land variant is almost two times lower than in the treated fields. The activity of microorganisms that assimilate mineral forms of nitrogen on the fallow land is high in the upper soil layers. The total quantity of microorganisms that decompose organic compounds and assimilate mineral forms of nitrogen is highest in the variant with an organic fertilization system. Organic fertilizers promote the development of soil bacteria and microorganisms, improve the course of biological processes in soils, and improve the physical and chemical properties of the soil.
