The influence of various resource-saving tillage and fertilizer systems on the agrochemical properties of light-gray forest soil in the grain crop rotation link "mustard – winter wheat – soybeans" is shown. The use of traditional, surfacial, minimal and zero technologies on light gray forest soils in the above-indicated rotation system provides an increase in the exchange acidity from 5.6 to 5.9 pH units, decrease in hydrolytic acidity from 2.80 to 1.65 meq/100 g of soil, an increase in the amount of exchangable bases from 11.5 to 13.3 meq/100 g of soil. Incorporation of plant residues (straw + stubble and root residues) is not sufficient to maintain a non-deficit humus balance within the three-year grain crop rotation; the deficiency is 0.06-0.18%. Zero soil cultivation provides a greater, by 29 mg/kg, increase in mobile phosphorus content compared to traditional plowing. Traditional plowing and zero technology on the background of the use of mineral and organic fertilizers together with ammonium nitrate (10 kg per 1 ton of straw) provide an increase in the content of exchangeable potassium. The use of mineral and biofertilizers promotes an increase in the yield of mustard and soybeans relative to the unfertilized variants in all methods of soil tillage. The Niva biopreparation (StiMiX trademark) had no significant effect on the formation and filling of winter wheat grains on all studied variants for tillage systems.
