KMB Liquid Biofertilizer

Potash Mobilizing Bacteria (KMB) are specialized soil microbes that solubilize fixed potassium (K) in soils, converting insoluble K-minerals into plant-available forms. Formulated at 1x10⁸ cells/ml, they enhance K uptake, improve crop quality, and reduce synthetic potash fertilizer dependency.

Product Specifications

• CFU: 1x10⁸ cells/ml

• Active Content: Strains like Frateuria aurantia (formerly Bacillus edaphicus), Bacillus mucilaginosus potash mobilizing bacteria

• Carrier: Liquid formula

Usage Instructions

1. Dosage: 2 ltr/acre mixed with 200 L water or compost.

2. Timing: Apply at sowing/transplanting; reapply at peak vegetative stage.

3. Primary Action: Solubilizes silicate minerals (e.g., orthoclase, biotite) to release K⁺ ions.

4. Method:

   • Soil: Blend with FYM/compost (1 kg/100 kg) and broadcast.

   • Seeds: Treat with 20 ml/kg slurry (use 10% starch adhesive).

5. Frequency: 2 applications per season (avoid waterlogged/acidic soils < pH 5.5).

6. Compatibility: Synergistic with PSB and Azotobacter; avoid chemical K-fertilizers for 20 days.

7. Activation: Requires silica-rich soils; produces organic acids (oxalic/citric) for K-mobilization.

8. Safety: Non-toxic to plants, soil fauna, or humans.

Suitable Crops

• Cereals: Rice (reduces "lodging"), Wheat (improves grain weight)

• Fruits: Banana (enhances bunch size), Grapes (increases Brix)

• Vegetables: Potato (boosts tuber size), Tomato (improves firmness)

• Cash Crops: Sugarcane (↑ sucrose content), Cotton (↑ boll weight)

• Legumes: Soybean (improves pod filling), Groundnut

Storage Instructions

• Temperature: 15–25°C (critical; avoid refrigeration or >30°C).

• Packaging: Can

• Shelf Life: 8 months 

• Precautions: Store in dark, dry conditions; discard if clumped or moldy.

Key Advantage

Silicate-Dissolving Efficiency:
Mobilizes 45–60 kg K₂O/ha/season from fixed soil reserves, increasing K-use efficiency by 30–50% in K-fixing soils (ICAR data). Reduces fruit cracking in tomatoes/pomegranates by improving cell wall strength.
