Alfisols

Alfisol Soils in the United States

Alfisols occur in the western areas of the southern forest. These soils tend to be strongly weathered, well developed, and contain a subsurface horizon in which clays have accumulated. They typically develop under under native deciduous forests. Coloring tends to run from dark brown to a light gray horizon as the soil evolves. The combination of favorable climate and high native fertility allows Alfisols to be very productive soils for both agricultural and silvicultural uses (Brady and Weil 1999).
