Acetobacter Liquid Biofertilizer

Acetobacter spp. (primarily Acetobacter diazotrophicus) are nitrogen-fixing, acetic acid bacteria that colonize sugar-rich crops, fixing atmospheric nitrogen (N₂) and producing growth-promoting compounds. Formulated at 1x10⁸ cells/ml in liquid formula they enhance yield and reduce synthetic N requirements in specific crops.

Product Specifications

• CFU: 1x10⁸ cells/ml

• Active Content: Live cells of Acetobacter diazotrophicus (or A. aceti)

• Carrier: Liquid Formula

Usage Instructions

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

2. Timing: Apply at planting/settling; reapply at tillering (sugarcane) or fruit set (pineapple).

3. Primary Action: Fixes N₂ in sucrose-rich tissues; solubilizes P/K; produces IAA (auxin).

4. Method:

   • Soil: Mix with farmyard manure (1 ltr/100 kg) and apply near roots.

   • Setts/Seedlings: Dip in 20 ml/L slurry for 30 minutes pre-planting.

5. Frequency: 2 applications per crop cycle (avoid alkaline/waterlogged soils).

6. Compatibility: Compatible with Azospirillum; avoid copper-based fungicides and high-N fertilizers.

7. Activation: Thrives in high-sugar exudates (pH 5.0–6.0); suppresses Leifsonia xyli (ratoon stunting disease).

8. Safety: Non-pathogenic; safe for soil fauna.

Suitable Crops

• Sugarcane (core host: fixes 30–60 kg N/ha)

• Sweet Sorghum (enhances juice sugar content)

• Pineapple (improves fruit size/Brix)

• Coffee (associates with roots in acidic soils)

• Rice (flood-tolerant strains for lowland varieties)

Storage Instructions

• Temperature: 15–25°C (critical; refrigeration kills acidophiles).

• Packaging: can

• Shelf Life: 8 months (extendable to 9 months with charcoal carrier).

• Precautions: Store in dark, dry conditions; discard if pH >7.0 or alcoholic odor develops.

Key Advantage

Sucrose-Linked Nitrogen Fixation:
Uniquely fixes N₂ inside plant tissues (not just rhizosphere), providing 20–40% of crop N needs in sugarcane while producing gibberellins that increase millable cane yield by 15–25% (IISR trials).
