Phosphate Solubilizing Bacteria (PSB) Liquid – Natural Bio-Fertilizer for Phosphorus Availability

Product Description:

              Phosphate Solubilizing Bacteria (PSB) is a powerful bio-fertilizer containing beneficial soil microbes capable of converting insoluble forms of phosphorus (like tricalcium phosphate, rock phosphate, and iron/aluminium phosphates) into soluble forms easily absorbed by plant roots.

Phosphorus is essential for root development, flowering, fruiting, and seed formation. Regular application of PSB enhances phosphorus use efficiency, reduces the need for chemical fertilizers, and improves soil health for long-term fertility.

This eco-friendly formulation is suitable for all crops and soil types and is a key component of organic and sustainable farming systems.

🌱 Key Benefits

1. Solubilizes unavailable phosphate into plant-available form
2. Promotes strong root development and early crop maturity
3. Enhances flowering, fruiting, and seed setting
4. Increases fertilizer efficiency and reduces P-fertilizer cost
5. Improves soil microbial activity and organic carbon
6. Eco-friendly, safe, and residue-free

🌾 Recommended Crops

Paddy, Wheat, Maize, Cotton, Sugarcane, Pulses, Groundnut, Banana, Grapes, Citrus, Mango, Papaya, Vegetables, Plantation Crops, and Flowers

🧪 CFU Count

2×10⁹ CFU/ml (Colony Forming Units per ml)

💧 Dosage & Application

1. Soil Application: Mix 1–2 litres per acre with 50–100 kg FYM or compost and apply near the root zone.
2. Drip Irrigation: Use 2 litres per acre through drip after filtration.
3. Seed Treatment: Mix 10 ml per kg of seeds, shade dry, and sow immediately.
4. Root Dipping: Mix 10 ml per litre of water and dip seedling roots for 20–30 minutes before transplanting.

⚡ Mode of Action

Phosphate Solubilizing Bacteria produce organic acids such as gluconic acid, citric acid, and lactic acid, which lower soil pH around the root zone, dissolving fixed phosphates into available orthophosphate ions (H₂PO₄⁻ and HPO₄²⁻). This ensures better phosphorus uptake, stronger roots, and improved yield quality.

🌿 Why Farmers Prefer Phosphate Solubilizing Bacteria

• Reduces dependency on chemical phosphate fertilizers
• Improves soil fertility and nutrient cycling
• Enhances flowering and yield naturally
• Safe for soil, plants, and environment
• Cost-effective and suitable for organic farming
  
  
  

❓ Phosphate Solubilizing Bacteria (PSB) – FAQs

❓ What is Phosphate Solubilizing Bacteria (PSB)?

Phosphate Solubilizing Bacteria (PSB) is a beneficial bio-fertilizer containing live soil bacteria that convert insoluble phosphorus in soil into plant-available forms, improving root growth and crop yield naturally.

❓ How does PSB work in the soil?

PSB produces organic acids that dissolve fixed phosphates in the soil and release them in soluble form, allowing plants to easily absorb phosphorus through their roots.

❓ Which crops can use PSB Liquid?

PSB Liquid can be used for all crops, including paddy, wheat, maize, cotton, sugarcane, pulses, groundnut, vegetables, banana, fruits, plantation crops, and flowers.

❓ What is the recommended dosage of PSB Liquid?

The recommended dosage is:

1. Soil application: 1–2 litres per acre
2. Drip irrigation: 2 litres per acre

❓ When should PSB be applied?

PSB should be applied during sowing, transplanting, or early crop growth stage for maximum phosphorus availability and strong root development.

❓ Can PSB reduce chemical fertilizer usage?

Yes. Regular use of PSB improves phosphorus use efficiency and helps reduce the requirement of chemical phosphate fertilizers, lowering input cost.

❓ Can PSB be used in organic farming?

Yes. PSB is 100% eco-friendly, residue-free, and suitable for organic and sustainable farming systems.

❓ Can PSB be mixed with other bio-fertilizers?

Yes. PSB can be mixed with Azospirillum, Azotobacter, Potash Solubilizing Bacteria, VAM, and organic manures. Avoid mixing with chemical fungicides at the time of application.

❓ What is the CFU count of this PSB product?

This product contains 2 × 10⁹ CFU per ml, ensuring high bacterial population and effective phosphorus solubilization.

❓ Does PSB improve soil health?

Yes. PSB improves soil microbial activity, organic carbon content, nutrient cycling, and long-term soil fertility.

❓ Is PSB safe for crops and the environment?

Absolutely. PSB is safe for crops, soil microbes, earthworms, farmers, and the environment and leaves no harmful residues.
