Norfolk soil and landscape

Soil profile: A representative soil profile of a Norfolk soil. Norfolk soils are characterized by a deep, loamy, yellowish brown subsoil that has redoximorphic features, areas of iron accumulations and iron depletions, in the lower part. (Soil Survey of Crawford and Taylor Counties, Georgia; by Alfred J. Green, Natural Resources Conservation Service)

 

Landscape: Corn (left) and wheat (right) growing in an area of Dothan-Norfolk complex, 2 to 6 percent slopes. Grass waterways and other conservation practices improve soil and water quality. (Soil Survey of Sumter County, South Carolina; by Charles M. Ogg, Natural Resources Conservation Service)
