Mycorrhiza formed symbiotic associations with roots of the plant, regulate biological activities, improve soil fertility, soil health, uptake of plant nutrient, enhance plant growth in acidic and saline soils, water stress and flooded conditions, tolerance of drought, salinity and transplantation shock. It also induces resistance in plants to soil borne diseases. It reduces the dosage requirement of phosphatic fertilizers and other micronutrients. Mycorrhiza fungus hyphae proliferate beyond the nutrient depletion zone reaching the source of nutrient.
