Alfisols are one of the 12 soil orders recognized by the USDA Soil Taxonomy. They are characterized by a subsurface horizon (usually within 1 m depth) that has accumulated clay, iron, and aluminum. Alfisols are found in a wide range of climates, from humid tropical regions to arid and semiarid environments, and are the most spatially widespread of the soil orders.
