Research theory. Because phosphorus fertilizers have been used extensively for a long time, the amount of Ca3(PO4) in the soil has increased. Ca3(PO4) is difficult to degrade and cannot be digested by plants. The plant is divided into the phosphorus element during the growing season as a result of separating the bacteria that break down Ca3(PO4) in the soil and transfer it to a state that can be absorbed by plants, as well as as a result of creating a bacterial fertilizer based on them and using it in practice. Demand is satisfiable.
The degree of study of the problem. Winter wheat has undergone extensive research to increase its phosphorus nutrition, primarily using mycorrhizal fungi from the species Acaulospora, Gigaspora, Glomus, and Silerocystus. Glomus mosseae was utilized for mycorrhization of grains in Pakistan by Maurya B.R. and Sanoria C.L. (1986), whereas in the United States by Rajaramamohan V. et al. (1987), Great Britain by Maurya B.R. (1986), India by Conde B.K., and Egypt by Shinde P.A. Mycorrhizal fungi are also noted to be used in grain inoculation by scientists like (1990). A medication called Mycofos was developed in India that contains the Bacillus polymyxa bacteria, which converts the difficult-to-decompose phosphorus compounds in the soil into a form that plants can readily absorb (Sanoria C.L., 1994). The culture fluids of Mycobacterium sp. SHt.12 TI and Mycobacterium sp. SHt.32 TI were utilized, according to Romanenko V.E. and Lisitskaya T.B. (2005) scientists. For winter wheat, Gilmutdinov M.G. (2006) utilized "Baikal EM-1" and "Tamir" preparations as well as phosphorite-based organo-mineral fertilizer. The soil bacteria and mycorrhizal fungi served as the basis for all of the aforementioned research.
However, utilizing biopreparations based on winter wheat rhizosphere bacteria, which have highly effective local phosphorus breakdown characteristics, can yield the best outcomes and indicators. There is currently no literature in existence that discusses these issues or offers solutions.
