Solution(By Examveda Team)
Aluminium toxicity is probably the important growth limiting factor in acid soils, particularly when pH is less than 5 to 5.5.Strongly acidic soils have high concentrations of soluble aluminium. Iron and manganese may be toxic to the growth of some plants. Soil acidity ultimately limits crop production.
