Microorganisms quantity dynamics of agrophytocenosis on the north-eastern slope of the Lesser Caucasus in Azerbaijan

Presented data on the dynamics of microorganisms depending on geographical location, geological-geomorphological and soil-climatic characteristics of the Ganja-Qazakh Massif of the Lesser Caucasus are presented. The number of aerobic and anaerobic diazotrophs in the rhizoenosis has been recorded depending on the seasonal dynamics. In the rhizoenosis of plants with the type of photosynthesis of C3 and C4 cultivated on different types of soils of the Ganja-Qazakh inclined plain, the C4 (maize) plant is characterized by a higher diazotrophic number than the C3 (winter wheat) plant and a significant taxonomic diversity.
