Acid Leaching

Acid leaching is a soil-making process. It happens in areas where there are lots of trees. Dead leaves and needles that fall from trees, rot on the ground to form soluble (leachable) products. These products include organic acids that remove mineral nutrients from the surface soil layer and carry the finer clay particles down into the subsoil. The layer beneath the surface. As a result, the surface soil tends to have few nutrients and are rough in texture. The bottom layer of soil has lots of clay and will soak up less water. The scientific name for such soils is Luvisolic soils. These soils dominate the boreal forest and foothills natural regions in Alberta.
