Abstract. In the first conditions of the Northern forest-steppe of the Tyumen region the influence of the main processing of leached chernozem and organic fertilizers on agrophysical properties, the yield of corn on silage is studied. As a result of the research on the influence of the main soil tillage on the agrophysical properties of the soil and the yield of corn, the best option of the main soil tillage was revealed. The density of the soil in the thirty-centimeter layer is characterized by crumbly addition of 0.98–1.02 g/cm3 before sowing corn; loose and dense (1.15–1.17 g/cm3) in the phase of 7th leave and dense (1.20–1.24 g/cm3) before harvesting for all the studied options. The best conditions for the stocks of available moisture in all phases of development of corn was on the way non-return 7.8–26.7 mm in twenty centimeters layer of 86.9–138.5 mm per meter compared to moldboard tillage. On average over two years of research in the cultivation of maize for silage on the main tillage in the northern foreststeppe of the Tyumen region according to the data of 2016 and 2017, an advantage was observed in the dump processing method, the maximum yield of corn obtained on non-return variant with organic fertilizers to 39.9 t/ha, subsurface method the reduction of green mass amounted to 5.3 t/ha. Organic fertilizers significantly increased the yield of green mass of corn in all methods of tillage, in the rejection of organic fertilizers decreased corn yield of 10.5 t/ha at non-return method and 9.3 t/ha for subsurface tillage method. The maximum yield was obtained at the control with the application of organic fertilizers – 39.5 t/ha.
