1. To remove soluble or other constituents from by the action of a percolating liquid: heavy rains that leached the leaching [ lē ′chĭng ] 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. When a chemical substance leaches or is leached from a material, especially soil, it is removed by the action of water passing through the material: The calcium, potassium, and magnesium ions are leached or washed out of the top soil into lower inaccessible subsoil. Leaching is the process of a solute becoming detached or extracted from its carrier substance by way of a solvent.
