DESILICATION It is the process by which silica, together with many bases, is removed from a soil profile by intense weathering and leaching. It is characteristic of humid, tropical areas and leads to development of ferralsol soils. Such soils often have low organic content because of rapid decomposition by micro-organisms.
LATERISATION This is a weathering process by which iron and aluminium oxides become concentrated in the upper layer of the soil. It is common in tropical and subtropical areas where wet and dry seasons alternate.
