Interaction of Phosphate-solubilising
Microbes with VAM
Common genera of V AM like Glomus, Gigaspora, Acaulospora, Sclerocystis and Entophosphora grow and increase phosphate uptake from the soil. They have the ability to improve the utilisation of unprocessed phosphatic urea or the rock phosphate which contain sparingly soluble phosphorus. Rock phosphate is the economic source of phosphorus particularly in acid soils and dual inoculation of phosphate-soluble bacteria Bacillus circulans and the VAM fungus Glomus sp. produces a synergistic effect by bringing about simultaneous solubilisation of insoluble phosphate and mobilisation of the same.
