Vesicular Arbuscular Mycorrhizae (VAM)
Mycorrhizae are mobilized major nutrients like, nitrogen, phosphorus and potassium and also certain micronutrients like zinc, calcium, iron, magnesium and manganese. Mycorrhizal inoculation enhanced absorption water, storage and movement back into plants enhances tolerance to drought. Mycorrhizae produce specific antibiotics, which immobilize and kill soil borne pathogens. Mycorrhizal inoculation reduces the chemical fertilizer application up to 40% from recommended dose.
Mode of action
The network of fungal filaments established simultaneously inside the roots and the surrounding rhizosphere soil to which the root system has access. Water and minerals from the soil are easily available resulting in a better nutritive equilibrium. These result in an increase in plant resistance to environmental stress such as drought, chilling and the detrimental effect of some root pathogens.
Fungi are heterotrophs and they benefit it by obtaining from their plant partners increased sources of carbohydrates, amino acids, vitamins and other elements which are essential for its growth and development. This interaction between plants and fungi creates a real symbiotic relationship and is advantageous to both the partners.
How to use VAM
In order to maximize the benefits of VAM for plant growth, health and yield, we recommend inoculation as early in the plant’s life cycle as possible. Direct inoculation of the root during germination or rooting can enhance the quality and quantity of mycorrhizal formation.
The key to success is to place VAM within one inch of the roots, so that the mycorrhizae can begin forming their beneficial symbiotic relationship with the plant.
Dosage and Application
Five kgs of VAM per Hectare is recommended along with the 1000 kgs of organic manure or vermicompost. VAM can also be applied along with other Bio-inputs. For horticultural crops and plantation trees apply 25 gms / plant.
