IRA Biotech 
NPK is a multi-functional microbial biofertilizer combining beneficial microorganisms for biological nitrogen fixation, phosphorus solubilization and potassium mobilization, supported by actinomycetes for improved organic-matter transformation and soil biological activity.
Produced using lyophilization (freeze-drying) technology to enhance microbial viability, stability and shelf life.
Composition
| Parameter | Detail |
|---|---|
| Microorganisms | Nitrogen-fixing microorganisms, phosphorus-solubilizing bacteria (PSB), potassium-mobilizing bacteria (KMB), actinomycetes |
| Microbial count | 3 × 10¹⁰ CFU |
| Technology | Lyophilization (freeze-drying) |
Mode of Action
The microbial consortium works through multiple biological pathways in the rhizosphere:
- Nitrogen fixation: beneficial nitrogen-fixing microorganisms convert atmospheric nitrogen into biologically available forms, supporting plant nitrogen nutrition.
- Phosphorus solubilization: PSB helps release fixed and poorly available phosphorus in the soil, improving phosphorus availability around the root zone.
- Potassium mobilization: KMB helps mobilize potassium bound within soil minerals, improving its availability for plant uptake.
- Actinomycetes support: actinomycetes help decompose complex organic materials and support organic-matter transformation, humus development, nutrient recycling and soil carbon cycling.
Key Benefits
- Makes N, P, K and micronutrients available to the plant.
- Helps in biological nitrogen fixation.
- Improves the availability of phosphorus.
- Mobilizes soil potassium for plant uptake.
- Promotes stronger roots and vigorous vegetative growth.
- Improves nutrient-use efficiency and rhizosphere activity.
- Improves organic-matter decomposition and soil carbon cycling.
- Improves long-term soil biological fertility.
- Helps plants overcome biotic and abiotic stress.
- Reduces the application of chemical fertilizers.
Dosage and Application
Recommended dose: 1 litre for 2 acres.
- Foliar application: dilute 1 litre in 300–400 litres of water and spray uniformly over 2 acres.
- Drip / fertigation: apply 1 litre through the drip or fertigation system for 2 acres with sufficient irrigation water.
- Soil application: mix 1 litre with 100–200 kg of well-decomposed FYM / compost or a suitable organic carrier, broadcast uniformly over 2 acres and follow with irrigation.
Recommended Crops
Cereals, pulses, oilseeds, vegetables, fruit crops, horticultural crops, plantation crops, 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.
