aref2 1 The effect of different doses of afteralcohol grains on the yield and quality of spring wheat, as well as the agrochemical properties of light gray forest soil, has been considered. The object of study was waste from the technological cycle of the Chugunovsky distillery in the Vorotynsky district of Nizhe- gorodskaya oblast. It was found that the use of afteralcohol grains as a fertilizer increased the aboveground biomass of spring wheat by 38-53%. It was shown that afteralcohol grains have no inhibitory effect on the plants in the studied dose range; however, the positive effect of their application is reduced with increasing doses to more than 200 mL/pot. The application of increasing doses of afteralcohol grains increases the contents of nitrogen, phosphorus, and potassium in wheat in the fertilized variants by 6, 5, and 13 rel %, respectively. It was proved that the introduction of afteralcohol grains contributes to the deterioration of physical and chemical properties of light gray forest soil: at the application of the maximum dose of afteralcohol grains, the pHKCl value decreased by 0.4 units, total acidity increased by 0.3 meq/100 g soil, and the degree of base saturation decreased by 3% compared to the control. The effect usually depends on the dose of afteralcohol grains. In the treatments with the application of afteralcohol grains, an increase in the content of mobile forms of major nutrients was noted.
