Since ancient times white lupin was largely widespread in the Mediterranean region and in the Middle East, due to its soil amelioration properties and because it develops well on acidic soils. It tolerates a soil acidity up to pH = 6.5, while alkaline or organic soils aren’t suitable. The soil must be well drained and loose, because lupin is easily subject to root asphyxia. White lupin flourishes in the same climatic zones of maize, although lupin, except at the beginning of the growing season, requires little water, because it has a long tap root.
