Aluminum toxicity in crop plants

Abstract
Aluminum toxicity can be an Important growth limiting factors occurring on acid soils where crop yields may be Increased if Al availability is reduced. A combination of liming to reduce plow layer Al plus the selection of plant species or cultivars within species that tolerate high subsoil Al are potential solution. Aluminum toxicity, Al tolerance mechanisms, physiological and biochemical effects of Al on plant growth, plant species tolerance to Al toxicity and methodology for Al screening are discussed.
