АКТИВНОСТЬ ФОСФАТМОБИЛИЗУЮЩИХ БАКТЕРИЙ В ОРОШАЕМЫХ ТИПИЧНЫХ СЕРОЗЕМНЫХ ПОЧВАХ ПО ВИДАМ СЕЛЬСКОХОЗЯЙСТВЕННЫХ КУЛЬТУР

Abstract

The article presents the results of studies of the activity of phosphor-immobilizing bacteria depending on the type of crops in typical irrigated gray-earth soils. One of the global environmental problems of agriculture around the world is the problem of soil phosphating, which arose as a result of the annual introduction of a large amount of phosphorus fertilizers into the soil for agricultural crops. It was found that the activity and state of soil phosphorus decomposers vary depending on soil conditions, the intensity and direction of soil formation processes, as well as on the types of crops, the amount of SO2 in the soil and the intake of humus.The soils sown with wheat, corn, sunflower, carrots, onions were dominated by species of Bacillus subtilis, Bacillus mycoides. The rapid development of Bacillus subtilis species indicates the active decomposition of plant residues and hard-to-digest organic substances.To create digital soil maps of nutrients in the soil, the key points were determined by entering the values of the amount of phosphor mobilizing agents in this section into the corresponding points on the map of soil quality determination points, where the key zone is located, and spatial distribution. the amount of substances in the key area.
