Description : The transfer of minerals from top soil to subsoil through soil-water is called? (1) Percolation (2) Conduction (3) Leaching (4) Transpiration

Last Answer : (3) Leaching Explanation: Leaching refers to the loss of water-soluble plant nutrients from the soil, due to rain and irrigation.
