The paper presents the research results of pre-sowing seeds bacterization with nitrogen fixing bacteria Bradyrhizobium japonicum and Azospirillum brasilense influence on the loss of moisture, water soluble humus and nutrients. It was shown that seeds bacterization reduces the leaching intensity of nitrates, phosphorus, potassium, calcium and magnesium. Moreover, the least losses of nutrients were observed in a variants with joint application of both studied nitrogen fixing microorganisms. It was noted that seeds bacterization with B. japonicum and A. brasilense had promoted increase of chlorophyll content in the leaves of soybean plants. The highest yield was observed in the variant with the joint use of rhizobia and azospirillum.
