Population dynamics of symbiotrophic and phosphate-mobilizing components of R. leguminosarum and Streptococcus sp. 35 artificial bacterial associations and their interaction with dominating in rhizosphere pea and vetch microorganisms was analyzed. Physiological and chemical properties of binary symbiotrophic and phosphate mobilizing inoculants of pea (R. leguminosarum bv. pisum 5114 + Streptococcus sp. 35) and vetch (R. leguminosarum bv. vicia 2303 + Streptococcus sp. 35) were studied. It was shown that the competitive substitution of symbiotic introduced microorganisms by the dominant microorganisms of legumous plants rhizosphere did not occur. Interaction character of rhizobial introduced microorganisms with studied microorganisms was the following: with the oligonitrophilic microorganisms – mutualistic; with the ammonifying ones (including the spore-forming forms) – neutral; with assimilating the mineral nitrogen – from neutral till possible competitive. Population magnitude of phosphate-mobilizing Streptococcus sp. 35 in the conditions of subculturing with the resident bacteria was lowered. Presumably, the population dynamics of introduced plants to a greater extent was determined by the content and availability of organic compounds in soil
