Aredale soils have thicker A horizons and have a higher average sand content in the solum. Lamont soils are more sandy throughout the solum. Orwood soils are on similar landscape positions as the Bassett, Racine, Aredale, and Lamont soils. Winneshiek soils typically are downslope. Permeability is moderate.
Surface runoff is medium or rapid.
Commonly used for cultivated crops. Corn, soybeans, small grains, and legume hays are grown. The more sloping Orwood soils are used for pasture or trees. Orwood soils occur near the local loess sources and eolian sand areas in northeastern Iowa and possibly adjoining states. Winneshiek County, Iowa, 1974.
