Aluminum (Al) is one of the major factor limiting plant growth and crop production in acidsoils (pH<5.5) that cover approximately30%of the world’s total land area and more than50%of the world’s potentially cultivated area. At neutral pH, Al is in the form ofinsoluble silicate or oxide. However, when the pH decreases below5.0, Al is solubilizedmainly in the form of Al3+and absorbed by plants to cause damages.
