Some researcher reported that N compounds in the form of NH4NO3 support growth of strains of phosphate-solubilizing bacteria and also support perfectly their activity in phosphate solubilisation.
• one study found an increase in the plant growth response to mycorrhizal infection in the presence of NO3−
• Other works have shown that mycorrhizal plants prefer NH4+ as N source
A very impressive account of answer is put forth by Dr Hani . This is how AMF can act in a role of centre staging multiple roles of nutrient cycling vis-a-vis plant growth . That is why , I flag off another issue , how effectively , one can exploit the AMF-based microorganisms in meeting out the nutrient requirement through number of soil borne solubilisation processes.
Yes Annop Kumar and Ghina, the answer of Dr. Hani is excellent explaining the phenomena working her and the role of bacteria in solubalizing P from rock phosphate.
