Abstract

The article carried out field and laboratory studies to study the dynamics of changes in the number of microorganisms in typical irrigated gray soils and meadow soils, depending on tillage and season. It has been established that the largest number of microorganisms corresponds to the spring season, processing, fertilizing and watering planted crops create the basis for the growth of microorganisms. By the summer season, an increase in air temperature and a decrease in humidity cause a decrease in the number of microorganisms. A slight increase in the number of microorganisms in the autumn season compared to the summer season was noted due to the influence of soil and air temperature.
