IRA Biotech 
URI-H is a microbial biofertilizer formulated with Azotobacter spp., Azospirillum spp. and Nostoc spp. The consortium supports biological nitrogen fixation and improves nitrogen availability to plants, promoting healthy growth, root development and sustainable crop nutrition.
Produced using lyophilization (freeze-drying) technology to enhance microbial viability, stability and shelf life.

| Microbial count | 1 × 10¹⁰ CFU |
| Technology | Lyophilization (freeze-drying) |
Mode of Action
Beneficial nitrogen-fixing microorganisms establish in the soil and rhizosphere and fix atmospheric nitrogen, contributing to plant nitrogen nutrition. Their activity also supports root development, nutrient uptake and beneficial soil microbial activity.
Key Benefits
- Ensures biological nitrogen fixation.
- Provides a sustained biological source of nitrogen.
- Promotes root development, vegetative growth and crop vigour.
- Improves nutrient uptake through soil biological activity.
- Supports reduced dependency on conventional nitrogen fertilizers, by about 20–30%.
- Enhances the production of plant hormones and reduces harmful pathogen infection.
- Increases plant tolerance to salinity and drought.
- Safe, organic-certified formulation.
- Enhanced microbial stability through lyophilization technology.
Dosage and Application
Recommended dose: 1 litre per acre, applied 10 days after sowing, at the vegetative stage and at the fruiting stage.
- Foliar application: dilute 1 litre in 150–200 litres of water per acre and spray uniformly over the crop.
- Drip / fertigation: apply 1 litre per acre through the drip or fertigation system with sufficient irrigation water for uniform distribution.
- Soil application: mix 1 litre with 50–100 kg of well-decomposed compost / FYM or a suitable organic carrier per acre, broadcast uniformly and follow with irrigation.
Recommended Crops
Cereals, pulses, oilseeds, vegetables, horticultural crops, fruit crops, plantations, commercial crops and pastures.
Compatibility
Compatible with most biological and organic agricultural inputs. Avoid direct mixing with bactericides, disinfectants or strongly antimicrobial products.
Storage
Store in a cool, dry place away from direct sunlight and excessive heat. Keep the container tightly closed.
