The aluminum-rich representative of laterite is bauxite.Laterite soils are rich in bauxite or ferric oxides. They are very poor in lime, magnesia, potash and nitrogen. Sometimes, the phosphate content may be high in the form of iron phosphate. In wetter places, there may be higher content of humus.
