The zone of leaching is the layer of soil where minerals are dissolved and removed from the soil. This occurs through the process of water percolating down through the soil, carrying minerals with it as it goes. As the water reaches the bedrock or another impermeable layer, it stops moving downward and begins to move laterally, creating a layer of soil in which the minerals have been leached out, leaving behind a less fertile layer.
