Microbes as Biofertilizers:**
-
Nitrogen-Fixing Bacteria: Certain bacteria, such as Rhizobium and Azotobacter, are used as biofertilizers because they can fix atmospheric nitrogen into a form that plants can use. These bacteria establish symbiotic relationships with leguminous plants, enhancing nitrogen availability in the soil.
-
Phosphate-Solubilizing Bacteria: Bacteria like Bacillus and Pseudomonas have the ability to solubilize phosphates in the soil, making phosphorus more accessible to plants. This improves plant growth and nutrient uptake.
-
Mycorrhizal Fungi: Mycorrhizal fungi form mutualistic associations with plant roots, increasing the plants’ nutrient and water absorption capacities. They are used as biofertilizers to enhance plant health and productivity.
