FACTORS AFFECTING PHOSPHORUS SOLUBILIZATION AND THE ROLE OF PHOSPHATE-SOLUBILIZING BACTERIA IN AGRICULTURE

Tóm tắt

The study involved gathering relevant literature on inorganic phosphorus-solubilizing bacteria and their role in agriculture. The review provides basic knowledge about the factors influencing the phosphorus solubilization process by bacteria in the soil, which in turn can lead to applications of these bacterial groups. Phosphorus (P) is crucial in regulating plant metabolism and health. Phosphorus exists in the soil in an insoluble form, and plants cannot utilize insoluble phosphate forms in the soil. The application of phosphate-solubilizing bacteria (PSB) is an effective method for converting insoluble phosphorus into soluble forms. However, the phosphorus solubilization efficiency of PSB is significantly affected by environmental factors such as temperature, pH, salt concentration, substrate concentration, type of microorganisms, incubation time, etc. Therefore, it is necessary to control the factors that affect the phosphorus solubilization process of PSB in the soil, creating optimal conditions for the activity of the PSB group during their application.
