Modern agro-industrial technologies, in particular, the production of grapes, require a large amount of mineral and organic fertilizers, intensive soil cultivation of inter rows of the vineyard to obtain large yields. Such anthropogenic pressure exerted on the ampelocenosis leads to soil degradation, to the disruption of its water and physical properties, to a decline in soil fertility. To prevent negative consequences and improve the overall condition of the ampelocenosis, elements of biologization are used: increasing the biodiversity of the agroecosystem by introducing effective strains of microorganisms and grassing the soil of inter rows of the vineyard with perennial grasses. Our research has shown that the introduction of Muscat white grape into the rhizosphere increased the number of bacteria of ecological and trophic groups, especially significantly against the background of a mixture of herbs. A strong correlation was established between the content of nitrate nitrogen and mobile phosphorus in the rhizosphere of grapes and the number of bacteria utilizing hardly soluble nitrogen and phosphorus compounds. Yields largely depended on the content of phosphate-mobilizing bacteria and mobile phosphorus in the rhizosphere of Muscat white grapes.
