Mycorrhiza
A mycorrhiza is an association between a fungus and plant roots in which the partners exchange resources. Such relationships can influence nutrient uptake and plant performance, but their effects depend on the fungus, host, soil, and management. The general concept does not prove that a purchased inoculant will improve every mango tree. Healthy soil conditions, suitable nutrition, and limited unnecessary root disturbance remain important. Do not treat a commercial microbial product as a substitute for correcting drainage or another clear root-zone problem.
