clay is the type of soil that is formed by leaching process.
which type of soil is formed by leaching process?
clay
leaching (pedology)









































in pedology, leaching is the removal of soluble materials from one zone in soil to another via water movement in the profile. 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.









































laterite soil, which develops in regions with high temperature and heavy rainfall, is an example of this process in action.

the leaching process in a salty soil to be reclaimed is illustrated in the leaching curves of figure 1, derived from data of the chacupe pilot area, peru. it shows the soil salinity in terms of electrical conductivity (ec) of the soil solution with respect its initial value (eci) as a function of amount of water percolating through the soil. the top-soil leaches quickly. the salinity of the deeper soil first increases due to the salts leached from the top-soil, but later it also decreases.
