Why Choose Astha Bio-Fertilizers?

A technical look at how microbial cultures outperform traditional chemicals.

Feature	Astha Bio-Fertilizers	Chemical Fertilizers
Nutrient Source	Living Microorganisms (CFU)	Synthetic Salts / Chemicals
Soil Health	Improves texture & carbon	Leads to acidity & hardening
Cost Benefit	Reduces Urea/DAP cost by 25%	Expensive & price-volatile
Residual Effect	Multiplies in soil (Long-term)	Short-lived (Washes away)

How to Apply Correctly

For maximum efficacy of microbial cultures (CFU), follow these methods:

Seed Treatment: Mix 10ml/gm with 1kg seeds. Dry in shade.
Soil Application: Mix 1L / 2kg with 100kg organic manure per acre.
Drip/Sprinkler: Use liquid formulas for direct root uptake.

💡 Pro Tip: Using Astha PSB and Azotobacter together unlocks "locked" soil nutrients immediately.

The Science of Soil Life

Astha Bio-fertilizers are not just plant food; they are living inputs. We use specific strains like Rhizobium, Azotobacter, and VAM to restore the natural breathing ecosystem of your soil.

✅ 15-25% Higher Yield

✅ Eco-Friendly & Safe

✅ Restores Microbial Balance

✅ Certified Organic Input

⚠️ Caution: Chemical Gap
Do not mix bio-fertilizers with chemical fungicides or antibiotics. Maintain a gap of 7 days between applications.

❄️ Proper Storage
Store in a cool, dry place away from direct sunlight. These are living bacteria—keep them away from acidic fertilizers.
