leaching  (lchng)
The removal of soluble material from a substance, such as soil or rock, through the percolation of water. Organic matter is typically removed from a soil horizon and soluble metals or salts from a rock by leaching. Leaching differs from eluviation in that it affects soluble, not suspended, material and often results in the complete removal of the material from the soil or rock.
