What is the primary role of Mycorrhizae in biofertilizers?

Mycorrhizae are beneficial fungi that form a symbiotic relationship with plant roots. They can help to solubilize inorganic phosphorus in the soil and make it available for plant uptake. This improves the phosphorus nutrition of plants, which is essential for growth, development, and yield. Mycorrhizae in biofertilizers also contribute to plant growth and development by enhancing water uptake, improving soil structure, and increasing resistance to diseases and pests.

Mycorrhizae do not fix nitrogen and are not involved in releasing potassium or chelating iron.
