The results of the study on the influence of the method of basic cultivation of soil and organic fertilizers obtained at the outlet of biogas plants, on organic and organo-mineral fertilizer systems on the agrophysical indices of sod-podzolic soils for the cultivation of spring wheat of Claris in the conditions of the Precarpathian region are presented. The study was completed for 2016-2018 at the fields of the FG "Fortuna" in the village Negivci of Kalush district of Ivano-Frankivsk region. It was established that the use of organic fertilizers obtained at the outlet of biogas plants, on organic and organo-mineral fertilizer systems and methods of basic soil cultivation positively influenced the structure of sod-podzolic soils in the technology of growing wheat wheat. The most agronomically valuable aggregates (0,25-10 mm) were in the form of surface cultivation of the soil for the organo-mineral fertilizer system at the time of sowing – 62,4 %, or 3,7 % more compared with the control and before harvesting the crop – 61,6 %, or 3,8 % more compared to the control. In the same variant, the coefficient of soil texture was the highest – 1,66 for sowing time and 1,60 for harvesting, or respectively 0,24 and 0,22, in comparison with that exceeding the indicator on the control. According to the organomineral system of fertilizer in the form of surface cultivation of soil (discovery at a depth of 8-10 cm), soil density at the time of sowing wheat in a layer of 0-10 cm was 1,16 g / cm3, in a layer 10-20 cm – 1,18 g / cm3, which is 0,05-0,06 g / cm3 less than that of the control. Before harvesting wheat, the spring density in the soil layer of 0-10 cm was 1,21 g / cm3, 10-20 cm – 1,23 g / cm3, which is, respectively, 0,03 and 0,02 g / cm3 less than the control. The total coarseness of the soil layer 0-10 cm behind the organic fertilizer system in the variant of the surface (8-10 cm) cultivation of the soil at the time of sowing wheat was 53,4 %, for organo-mineral – 54,2 %, which respectively 4,4 % and 5,2 % more compared to the control; in the layer of soil 10-20 cm they were respectively 52,8 % and 53, 1% and 4,1 and 4,4 %. Before harvesting the crop for the organomineral system of fertilizer, the total spurability in the layer of soil 0-10 cm was 53,7 %, 10-20 cm – 52,6 %, which, respectively, 5,9 % and 4,6 %, exceeded the indicators for control; for the organic fertilizer system they were respectively 52,3 % and 51,8 % and 4,5 % and 3,8 % respectively.
