THE EFFECT OF ASSOCIATIVE DIAZOTROPHS ON THE MICROBIOLOGICAL ACTIVITY OF SOIL DURING THE CULTIVATION OF GRAIN AND LEGUMINOUS CROPS

Based on the research of many years, it was established that the use of pre-sowing inoculation of seeds of cereals and legumes with biological preperations has a positive effect on the microbiological activity of the soil in the rhizosphere of the crops, increasing their quantity, the ratio of individual groups, the direction of processes, contributing at the same time to an increase in productivity. Determined that, the effect of the preparations is characterized by varietal specificity, depends on the prevailing hydrothermal conditions, the nutritional regime of the soil, and is determined by the effectiveness of the specific preparation and strain.
