The effect of the inoculation of soybean seed preparation “rizotorfin”containing a strain of symbi-otic bacteria Risobium japonicum, and preparations containing carboxymethyl cellulose, synthetic and organic in the number of bacterial and fungal microflora leached chernozyom and symbiotic ac-tivity of soybean varieties of “Hope” was studied. Investigations were carried out in an experimental field on a small plot of moderately arid and forested steppe of the Altairegion. The drugs used both separately and in combination with rizotorfin. A sig- nificant increase in the black soil microbial activity in the processing of soybean seeds with rizotorfin both separately and together carboxymethylated drugs. The number of bacteria using organic forms of nitrogen increased to 1.6-2.2 times, the number of flora growing on KAA and using mineral forms of nitrogen in the 1.1-2.3 times, the number of fungi was reduced to 1.2-1.9 times, nitrogenase activity of soybean increased by 1.9 times. The greatest increase observed when using carboxymethyl preparation of oat chaff together with rizotorfin.
