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 soil texture & carbon | Leads to acidity and hardening |
| Cost Benefit | Reduces urea/DAP cost by 25% | Expensive and price-volatile |
| Residual Effect | Long-lasting (multiplies in soil) | Short-lived (washes away) |
| Eco-Safety | 100% Non-toxic & Sustainable | Can pollute groundwater |
Pro Tip: Using Astha PSB and Azotobacter together can increase your fertilizer efficiency by making “locked” nutrients in the soil available to the roots immediately.
How to Apply Bio-Fertilizers Correctly
For maximum efficacy of the microbial cultures (CFU), follow these methods:
- Seed Treatment: Mix 10ml/10gm of Astha Bio-Fertilizer with 1kg of seeds. Dry in shade before sowing.
- Soil Application: Mix 1 Litre / 2kg of Bio-fertilizer with 100kg of organic manure/vermicompost and apply to 1 acre.
- Drip/Sprinkler: Use the liquid base formulas directly in the irrigation system for rapid uptake.
Caution: Do not mix bio-fertilizers with chemical fungicides or antibiotics. Keep a gap of 7 days between applications.
The Science of Astha Bio-Fertilizers
Bio-fertilizers are not just plant food; they are living inputs. Our range includes Rhizobium for pulses, Azotobacter for non-leguminous crops, and VAM (Vesicular Arbuscular Mycorrhiza) for enhanced nutrient uptake. By using these microbial cultures, you ensure a living, breathing soil ecosystem.
Key Advantages:
- Cost Effective: Significantly reduces the cost of chemical fertilizers.
- Soil Health: Improves soil structure and restores natural microbial balance.
- Environmentally Safe: Non-toxic, eco-friendly, and safe for organic farming.
- Increased Yield: Leads to 15-25% higher productivity in various crops.
