Dynamics of the number of microorganisms distributed in irrigated typical soil and grass soils by seasons

Abstract Biological preparations developed on the basis of biological methods have been considered the mainstay in the protection and fight against various diseases occurring in plants. It has been proven that the main resource in strengthening the biological condition and fertility of the soil is closely related to the life of saprophytic microorganisms. In this place, microorganisms and microbiological processes in the soil have performed an important task. In particular, it has the characteristic of enriching the soil with biological nitrogen due to the normalization of organic matter in the soil, assimilation of free nitrogen in the air by nitrogen-receiving microorganisms. In the article, it was observed that the amount of microorganisms in the composition of typical irrigated gray and meadow soils changes according to the seasons. It was explained that the highest amount of microorganisms was determined in the spring season, it decreased in the summer season, in autumn, the soil temperature and air temperature increased the amount of microorganisms, and in this season, if the activity of microorganisms is observed in the 0-30 cm layer of the soil, it was observed that it decreases towards the lower layers.
