Abstract. Today, the growth of soybean production in the world is ensured by the increase of cultivated areas and the increase in productivity, and the average annual growth rate of the planted soybean area in the last ten years is 1.7 percent. "Therefore, the soybean yield per hectare increased by 1.0%, and the average yield was 28 centners per hectare." At the same time, the development of agrotechnological elements for placing soybean varieties in different soil conditions, increasing the yield and grain quality, including protein content and oil content. and scientific-research works on maintaining and increasing soil fertility are being carried out. In the conditions of light gray soils with low productivity of the republic, the cultivation of soybean as the main crop, the use of bio-organo-mineral fertilizers to increase the protein content and fat content of grain, the improvement of the agro-ecological conditions of the soil, and the development of agro-technologies wide implementation in the production industry is one of the urgent tasks of today.
