Biofertilizers are natural fertilizers that contain living microorganisms such as bacteria, fungi, or algae. They help plants grow by increasing the availability of nutrients in the soil.

Examples

  • Rhizobium – fixes nitrogen in the roots of legume crops like beans and peas.
  • Azotobacter – helps fix nitrogen for non-leguminous crops.
  • Phosphate-solubilizing bacteria (PSB) – make phosphorus available to plants.
  • Mycorrhiza – fungi that help plants absorb phosphorus and water more efficiently.
  • Blue-green algae (cyanobacteria) – fix nitrogen, especially in rice fields.

Advantages

  • Improve soil fertility 🌱
  • Reduce the need for chemical fertilizers
  • Increase nutrient availability
  • Environment-friendly and generally safe
  • Can improve crop growth and yield

In simple words: Biofertilizers are useful microorganisms that naturally supply or make nutrients available to plants.
