They are analyzed changes in yields of winter wheat were seeded on black fallow, of millet sown on winter wheat, of spring wheat were seeded on millets with the distance from shelterbelt forest belt (field-protective forest belt) by basic tillage method soil on the background of nitrogen fertilizers and on the natural background of fertility were analyzed. Regardless of the distance to the crops from the shelterbelt forest belt, it is agronomically expedient and energetically beneficial to use

In all the years of research, the yield of a winter crop increased by a significant amount of fertilizer when the plots finding from the shelterbelt forest belt were located at a distance of 130 m on the options of plowing and subsurface plowing. Nitrogen fertilizers in action for almost all the years of research, regardless of the distance between the plots and the shelterbelt forest belt, increased the crop yield by a significant amount for all soil treatment options. Regardless of the distance of the plots finding from the shelterbelt forest belt, a decrease in the yield of millet on both backgrounds was observed in the options of disking and subsurface plowing compared to the option of plowing. On average, over the years of observations, as well as in 2015 and 2017, both on a natural fertility background and in the aftermath of using nitrogen fertilizers when finding plots from the shelterbelt forest belt at a distance of 130 and 70 m after disking, the yield of spring wheat was by a significant amount lower than after plowing. In 2017, in a favorable background, regardless of the distance of the plots finding from the shelterbelt forest belt on the natural fertility background, the yield of spring wheat on the options for shallow plowing, subsurface plowing and disking was significantly lower than after plowing. Nitrogen fertilizers in the aftermath allowed to increase the yield of spring wheat on options for shallow plowing and subsurface plowing, which varied within the error of experience in relation to the option of plowing (control) when finding plots from the shelterbelt forest belt at a distance of 10 and 70 m.
