Dextrose Based Azotobacter Powder Formulation (Water Soluble)

Azotobacter spp. are free-living, nitrogen-fixing soil bacteria that enhance plant growth through nitrogen fixation, phosphate solubilization, and phytohormone production. Formulated at 5 × 10⁷ CFU/g on a talc carrier, they boost soil fertility and reduce synthetic fertilizer dependency.

Product Specifications

• CFU: 5 × 10⁷ per gram (50 million viable cells/g)

• Active Content: Live cells of Azotobacter chroococcum or A. vinelandii

• Carrier: Dextrose powder (pH 6.5–7.5 for optimal bacterial activity)

Usage Instructions

1. Dosage: 1–2 kg/acre mixed with compost or 200 L water for soil application.

2. Timing: Apply at sowing/transplanting; reapply at tillering/flowering stages.

3. Primary Action: Fixes atmospheric nitrogen (N₂ → NH₃); solubilizes insoluble phosphates.

4. Method:

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

   • Seeds: Treat with 20 g/kg slurry (use 10% gum arabic as sticker).

5. Frequency: 2–3 applications per crop cycle (avoid waterlogged soils).

6. Compatibility: Compatible with Phosphate-Solubilizing Bacteria (PSB) and Rhizobium; avoid chemical fungicides.

7. Activation: Requires well-aerated, moist soils (pH 6–8); suppresses Fusarium via siderophores.

8. Safety: Non-pathogenic to plants, humans, or animals.

Suitable Crops

• Cereals: Wheat, rice, maize (enhances tillering/grain filling)

• Vegetables: Tomato, cabbage, potato (improves N/P uptake)

• Legumes: Soybean, groundnut (synergizes with Rhizobium)

• Others: Sugarcane, cotton, horticultural crops

Storage Instructions

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

• Packaging: Breathable polyethylene bags (to prevent anaerobic death).

• Shelf Life: 6 months (extend to 9 months with lignite carrier).

• Precautions: Store in dark, low-humidity conditions; discard if odor develops.

Key Advantage

Nitrogen-Phytohormone Synergy:
Fixes 15–20 kg N/ha per season while producing IAA (indole-3-acetic acid) and gibberellins that increase root biomass by 40% and suppress Macrophomina phaseolina (charcoal rot).
