The Role of Phosphate-Solubilizing Microorganisms in Soil Health and Phosphorus Cycle: A Review

Abstract

The role of phosphate-solubilizing microorganisms (PSM) in soil health and Phosphorus (P) cycle is a crucial aspect of agricultural productivity. Recent research has emphasized the importance of microorganisms in maintaining soil health. Phosphorus is an essential macronutrient for plant growth and development and significantly affects crop productivity. The PSM solubilize phosphate by producing metabolites such as organic acids, inorganic acids, hydrogen sulphide, exopolysaccharide, and siderophore. Studies have shown that the combination of PSM with phosphate fertilizers increase the efficiency of the fertilizers in soils. The efforts have been made to integrate exogenous soil microorganisms into P cycling models. This review highlights the critical role of microorganisms in maintaining soil health and promoting P cycle, emphasizing the importance of incorporating them into soil management practices.
