nitrogen regime, humus, soil, soil tillage, nitrates, grain cropsAbstract
The influence of combined and zero soil tillage on the dynamics of nitrate and alkaline hydrolyzed nitrogen, the content of the total humus of common black soils under different systems of fertilizing grain crops of crop rotation are studied. The positive effect of minimum soil tillage on the content of moving nitrogen forms and the preservation of common humus in the arable layer of soil are determined
