Abstract

The results of researches in the stationary experiment on studying the influence of various systems of fertilization and soil cultivation on the dynamics of accumulation of nitrogen compounds in typical black soil under winter wheat are highlighted. The object of research was the soil cover. The dynamics of mineral nitrogen forms during 2012-2017 in winter wheat crops is given. The dependence of the level of nitrate, ammonium nitrogen and nitrogen compounds that is easily hydrolyzed from soil and fertilizer systems is investigated. It was established that the organo-mineral fertilizer system resulted in a significant increase of 35.8% of ammoniacal nitrogen and 24.4% nitrate compared to control. Mild polygonal and politsevo-bezpolatny soil cultivation significantly increased the content of ammoniacal nitrogen in the arable layer compared with differentiated treatment. Application of organo-mineral and mineral fertilizer system contributes to a significant increase in the content of nitrogen compounds that are easily hydrolyzed.
