Buy PSB Biofertilizer in Ranebennur, Karnataka 

Ranebennur farmers cultivating sugarcane, cotton, paddy, banana, groundnut, pulses, and vegetables know that phosphorus is the engine of root development, flowering, and fruit formation. But most soils in the region—especially black cotton and lateritic types—are rich in total phosphorus yet poor in plant-available forms. The result? Stunted growth, poor flowering, and low yields despite heavy DAP and SSP applications.

Phosphate Solubilizing Bacteria (PSB) offers a smarter solution. These beneficial soil microbes unlock locked‑up phosphorus naturally, reducing fertilizer costs while boosting crop health and productivity.

What is PSB Biofertilizer and How Does It Work?

PSB are naturally occurring soil bacteria that produce organic acids (citric, gluconic, and others) which convert insoluble phosphates (like tricalcium phosphate, rock phosphate, and iron/aluminum phosphates) into plant‑available forms. They don't just recycle native soil phosphorus; they also make applied chemical phosphates more efficient by preventing fixation.

Key actions include:

  • Unlocks Fixed Phosphorus: Solubilizes bound soil phosphates into soluble H₂PO₄⁻ and HPO₄²⁻ ions plants can absorb.

  • Boosts Root Development & Yield: Enhances root branching, tillering, flowering, fruit set, and crop maturity.

  • Reduces Fertilizer Costs: Can cut chemical phosphatic fertilizer (DAP, SSP) requirements by 25‑30%.

  • Improves Soil Health: Increases microbial activity, soil structure, and fertility while preventing phosphorus fixation.

  • Saves Money: Each hectare can save 40‑60 kg of DAP while increasing yields by 10‑20%.

  • Dual Nutrient Mobilization: Solubilizes 30–50 kg P₂O₅/ha/season while improving zinc and iron availability.

How to Use PSB Biofertilizer for Best Results

  • Seed Treatment: Mix 10‑15 g of PSB powder (or 20 ml of liquid PSB) with 10% jaggery solution per kg of seeds. Coat evenly and shade‑dry before sowing.

  • Soil Application: Apply 2 kg PSB powder (or 2 litres liquid) per acre mixed with 100‑200 kg well‑decomposed FYM or compost at final plowing.

  • Fertigation/Drip Irrigation: Dissolve 1‑2 kg of water‑soluble PSB powder per acre in 200 litres water and apply through drip system during vegetative and flowering stages.

  • Nursery Application: Blend 100‑200 g PSB powder per cubic metre of potting mix for healthy, robust seedlings.

  • Reapplication: Apply PSB twice per crop cycle—once at sowing/transplanting and once at flowering—for maximum phosphorus availability.

Important Precautions

  • Do not mix with chemical fungicides, bactericides, or heavy doses of chemical P‑fertilizers in the same tank; maintain a 15‑day gap.

  • Apply in moist, warm soil (25‑35°C) for optimal bacterial activity. Avoid application in highly alkaline soils (pH > 8.0).

  • Store in a cool, dry place (10‑25°C) away from direct sunlight and pesticides.

  • Use within shelf life: 8 months for liquid and 24 months for powder formulations.
