USK PSB

USK PSB

• It is soil inoculums which improves solubilization of chemically fixed soil phosphorus.
• Only 10-15% of applied phosphorus is utilized by plants and remaining 85-90% is fixed into soil in unavailable form so use of PSB is the need of hour to release Phosphorus into plant useable form.
• It produces organic acids such as lactic, succinic, citric, fumaric, gluconic and acetic acid which increase the availability of phosphorus in soil by the process of chelation and lowering soil pH.
• It produces amino acids, vitamins, growth promoting substances such as IAA and GA which helps in better growth of plants.
• It saves about 50% of phosphorus fertilizers applied to fields.
• It has synergistic effect on other beneficial microbes in the rhizosphere.
• It is compatible with other bio fertilizers.
