The ability of phosphorus-solubilizing fungi to solubilize or release bound or insoluble forms of phosphorus in the soil increases the amount of phosphorus that plants can absorb. The way phosphate-dissolving fungi work in biofertilizers is as follows:
Phosphate solubilization: Organisms that break down phosphates produce phosphatases and organic acids including citric, gluconic, and oxalic acids. These organic acids and enzymes aid in phosphorus solubilization from soil-bound forms like calcium phosphate or iron phosphate. PSF increase the availability of phosphorus to plant roots by transforming these insoluble phosphorus compounds into soluble ones.
Improved phosphorus uptake: Phosphate-dissolving fungi solubilize phosphorus, increasing its availability in the rhizosphere (the area around plant roots). This makes it possible for plants to absorb phosphorus more effectively, which results in increased growth.
Indirect root growth promotion is provided by phosphate-solubilizing fungus. Plants can spread their root systems more successfully as a result of improved access to phosphorus, which is essential for root development. This allows plants to explore more soil and absorb nutrients and water more effectively.
Enhanced nutrient use efficiency: Phosphate-dissolving fungi aid in enhancing nutrient use efficiency by increasing phosphorus availability. The requirement for excessive use of chemical phosphorus fertilizers is decreased since plants are better able to utilize the phosphorus that is already present in the soil.
