Mycorrhizae mobilizes major nutrients like phosphorus and potassium and certain micro-nutrients like zinc, calcium, iron, magnesium and manganese. Mycorrhizae inoculation enhances absorption of water, storage and movement back into plants and increases tolerance to drought. Mycorrhizae produce specific antibiotics, which immobilize and kill soil borne pathogens.
A mycorrhiza is a symbiotic association between a fungus and the roots of a vascular host plant. The term mycorrhiza refers to the role of the fungi in the plants' rhizosphere, its root system. Mycorrhizae play important roles in soil biology and soil chemistry.
Formerly known as vesicular-arbuscular mycorrhizas (VAM), mycorrhizas are found in 85% of all plant families, and occur in many crop species. The hyphae of arbuscular mycorrhizal fungi produce the glycoprotein glomalin, which may be one of the major stores of carbon in the soil.
