<P> In pedology, leaching is the loss of mineral and organic solutes due to very heavy rainfall, high temperature and percolation . It is a mechanism of soil formation distinct from the soil forming process of eluviation, which is the loss of mineral and organic colloids . Leached and elluviated materials tend to be lost from topsoil and deposited in subsoil . A soil horizon accumulating leached and eluviated materials is referred to as a zone of illuviation . </P> <P> Laterite soil, which develops in regions with high temperature and heavy rainfall, is an example of this process in action . </P>
