Adaptability of Wheat Varieties to Acid Soils

Abstract

IT is common experience that certain varieties of wheat can tolerate a considerable degree of acidity in soils, while other varieties, although botanically similar, are very sensitive to this condition. As work in recent years has shown that the soil acidity complex can be resolved into a number of separate factors¹, it was decided to investigate the importance of two of these factors—aluminium and manganese toxicity—in relation to the acidity tolerance of wheat varieties.
