DESCRIPTION

Phosphate solubilizing bacteria (PSB) produce essential organic enzymes that convert the insoluble phosphorus into soluble form for easy absorption by plants. Bacillus megaterium consumes the inorganic phosphorus and excretes the organic substance. It produces organic acids like citric acid, lactic acid and enzymes (such as phytase, nuclease, etc.) that help in the solubilisation of insoluble phosphates. PSB also regulates the production of Phytohormones like gibberellins and indole acetic acid. Gibberellins are responsible for cell elongation triggering growth, development and inducing seed germination. Indole 3 acetic acid is needed to promote uniform fruit and flowering and adventitious root development.

IMPORTANCE

Phosphorus is one of the major nutrients needed for plants in appropriate amounts, in addition to nitrogen and potassium. PSB improves the microbial content and activities in the soil, promoting plant health.The fertilizer regulates microbial activity in the rhizosphere region (The region around the root where nutrition exchange and water absorption takes place). Thus, PSB is an essential component for home gardens to regulate the soil inoculum and minimise the loss of phosphorus from soil. In addition, phosphorus fixes atmospheric nitrogen into the soil. In agricultural lands, the application of PSB facilitates phosphate-induced immobilization of metals to reverse soil contamination.

BENEFITS

• Add nutrients to the soil by nitrogen-fixing.
• Improves the organic content and microbial population of the soil.

MODE OF ACTION: Phosphate solubilising bacteria produce organic acids and enzymes that help in the solubilisation of insoluble phosphates into plant utilizable form. They also produce phytohormones like Indole acetic acid and gibberellins, which promote plant growth and yield. By improving the organic content and microbial population of the soil, Phosphobacteria improves the plant health.

Seed Inoculation: Mix 250gm of phosbact with 500ml of rice gruel or gum Arabica to make slury. Mix the seed required for an acre in the slurry and dry in shade for 30 minutes before sowing. The treated seeds should be sown within 48 hours.

Soil Application : Mix 3 to 5 kgs phosbact with 50 kgs Fine FYM Powder and apply to an area of 1 acre at the time of final land preparation.

Recommendation : For all types of crops

Packing Available  : 250gm & 1 Kg
