Investigating the Role of Solubilizing Bacteria in the Phosphorus Cycling and Organic Matter Dynamics

In alkaline calcareous soils, where phosphorus is usually immobile and unavailable for plant uptake, phosphorus solubilizing bacteria (PSB) are essential for increasing the bioavailability of phosphorus in soils. Through the synthesis of organic acids and other processes, these bacteria solubilize inorganic phosphate compounds, greatly enhancing the cycling of phosphorus. The purpose of this review is to explore how PSB enhances phosphorus availability and how it interacts with the dynamics of organic matter in alkaline calcareous soils, which are common in many arid and semi-arid regions. Important findings from the literature show that PSB interact with organic matter to improve soil fertility overall in addition to increasing phosphorus availability. Research have indicated that temperature, pH, and inputs of organic carbon all affect PSB activity. The review also emphasizes the challenges presented by environmental factors that limit bacterial efficaciousness in phosphorus solubilization, as well as the symbiotic relationship between PSB and other soil microorganisms. This review has significant outcome for environmentally friendly farming. Growers can encourage more economical and environmentally friendly farming practices by lowering their reliance on chemical phosphorus fertilizers by using PSB as biofertilizers. By promoting nutrient cycling, accelerating the breakdown of organic matter, and possibly raising carbon sequestration, PSB activity also contributes to the long-term health of the soil. For sustainable agricultural productivity and environmental conservation, this research emphasizes the significance of microbial interventions in managing nutrient-deficient soils.
