Solution
Biofertilizers: The biofertilizers are nitrogen fixing microbes or fungi which enrich the soil with nutrients.
There are 3 major types of biofertilizers i.e. bacterial biofertilizers, cyanobacterial biofertilizers and fungal biofertilizers.
Examples of biofertilizers:
- Nitrogen-fixing symbiotic bacterial biofertilizer - Rhizobium in root nodule of leguminous plants.
- Nitrogen-fixing symbiotic cyanobacterial biofertilizers - Anabaena azollae in Azolla.
- Nitrogen-fixing non-symbiotic cyanobacterial biofertilizers - Nostoc, Anabaena.
- Mycorrhizal Fungal biofertilizer - Ectotrophic mycorrhiza and Endotrophic mycorrhiza - VAM.
