IRA Biotech 
ZNB is a microbial biofertilizer formulated with Thiobacillus novellus, selected to support the biological mobilization and availability of zinc in the soil. The formulation helps improve access to poorly available zinc fractions in the rhizosphere, supporting balanced micronutrient nutrition, healthy crop development and improved plant metabolic activity.
Produced using lyophilization (freeze-drying) technology to enhance microbial viability, stability and shelf life.

Mode of Action
Thiobacillus novellus establishes microbial activity in the soil and rhizosphere. Through its metabolic activity and associated changes in the root-zone environment, it helps mobilize poorly available zinc compounds, improving the availability of zinc for plant uptake.
Adequate zinc nutrition supports several important plant processes, including enzyme activity, chlorophyll formation, protein metabolism, auxin-related growth and the development of new tissues.
Key Benefits
- Helps mobilize zinc in the soil.
- Improves zinc availability and plant uptake.
- Supports chlorophyll formation and healthy growth.
- Increases enzyme activity and plant metabolism.
- Increases root development, vegetative growth and crop vigour.
- Helps correct zinc-deficiency-related nutritional stress.
- Enhanced microbial stability through lyophilization technology.
Dosage and Application
Recommended dose: 1 litre per acre, applied in the evening hours.
- 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.
- 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, fruit crops, horticultural crops, plantation crops and commercial crops.
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.
