Biofertilizers are a type of organic input used in agriculture to enhance soil fertility and promote plant growth. They are composed of beneficial microorganisms like bacteria, fungi, and algae, as well as organic materials such as animal manure, plant residues, and compost. These microorganisms play a vital role in the natural nutrient cycling processes within the soil, making them a key component of organic farming practices.

The significance of biofertilizers in organic farming stems from their ability to fix atmospheric nitrogen, solubilize phosphates, and mobilize other essential nutrients. One of the most common types of biofertilizers is rhizobium bacteria, which form symbiotic relationships with leguminous plants like peas, beans, and clover. These bacteria reside in nodules on the roots of these plants and convert atmospheric nitrogen into a form that can be utilized by the plants, thus reducing the need for synthetic nitrogen fertilizers.

Another important type of biofertilizer is mycorrhizal fungi, which establish mutually beneficial relationships with the roots of many plants. These fungi extend the plant's root system, increasing its access
