Alfisols are soils developing under forest covers of the humid midlatitudes. Eluviation is moderate and base status is fairly high in these soils. Common to the humid continental (like the one in Michigan on the above) and humid subtropical climates, these soils are well developed and contain a subsurface layer of clay called an argillic horizon
