The purpose of work to define the conditions for effective combinations of mineral fertilizers and microbial products in the technology of winter wheat. Methods of investigation are standard methods of microbiological, biochemical, agrochemical, field studies and mathematical statistics. Ecological reasonable dose of mineral nitrogen for winter wheat growing on meadow black soil with application of biopreparations and without them are defined using the indicators of flow processes of associative nitrogen fixation, and biological denitrification. Physiological and environmental appropriate doses is input 60 kg / ha nitrogen fertilizers. Compromise dose is 90 kg / ha. Dose of 120 kg / ha is unacceptable from the ecological aspect. Range of environmental acceptable doses of nitrogenous fertilizers expands with application of biopreparations, as plants initiated of inoculation need more nitrogen for constructive metabolism. Under these conditions, ecological appropriate dose was 90 kg / ha of mineral nitrogen.
