Abstract. Relevance. Assessment of the microbiological activity of light chestnut irrigated soils of the Lower Volga region in biologized agriculture is of great importance for ensuring product safety and protecting human and animal health. The purpose of the study is to analyze the functioning of the soil microbiota, which allows us to identify the presence of microorganisms that affect soil fertility. Assessment of the microbiological activity of light chestnut irrigated soils of the Lower Volga region is an important tool for monitoring biological safety and developing methods of biologized agriculture. The object of the study was the irrigated light chestnut soils of the Lower Volga region, the peculiarities of the development of microbiota in experimental plots under various humidification regimes using sideral crops as precursors. Materials and methods. The experiment was conducted in 2024 by order of S. I. Fokin on the soils of the fields of the farm, which is located on the territory of the Gorodishchenskiy district of the Volgograd region. A two-factor field experiment was conducted in the fields of the farming of S. I. Fokin in order to study the effect of the moisture regime and the precursor crop on soil fertility, and, consequently, on the yield of cultivated crops. Factor A is a humidification regime in which irrigation was carried out with a decrease in soil moisture to 65, 75 and 85 % of the lowest moisture capacity. Factor B – variants of precursors: carrots, black steam (steam without sowing, treated to kill weeds), winter rye for siderate and all possible combinations of these humidification modes and precursors. Scientific novelty. The data from the field experience made it possible to conduct a microbiological assessment and obtain data on its activity depending on the moisture regimes according to the variants of the precursors, which is necessary for the development of measures to restore and preserve soil fertility. Data on the respiration of soil microorganisms on the intensity of CO2 emission and the cellulose-destroying microbiota of light chestnut irrigated soils during the embedding of sideral crop biomass were obtained. Results. The presented research results, aimed at substantiating the application of biologization techniques (the use of green manure and a selected irrigation regime), contribute to increased soil respiration and accelerated organic matter decomposition.
