Main types
- Rhizobium: nitrogen fixation in pulses and legumes (each crop group needs its own strain).
- Azotobacter and Azospirillum: nitrogen fixation for cereals, vegetables and other non-legumes.
- PSB (phosphate solubilising bacteria) and KSB/KMB (potash solubilising/mobilising bacteria).
- Mycorrhiza (VAM): improves uptake of phosphorus and water.
- Blue-green algae and Azolla: used in paddy fields.
How to apply
- Seed treatment: coat seeds with biofertilizer just before sowing and dry them in shade.
- Seedling root dip: dip roots of transplanted crops before planting.
- Soil application: mix with compost or FYM and apply to the field.
Handle with care
- Store in a cool, shaded place and use before the expiry date (they are living organisms).
- Do not mix directly with chemical fungicides or apply at the same time; treat with fungicide first if needed, as the label advises.
- Buy products that meet the standards of the Fertiliser (Control) Order.
