Dubuque, Exette, and Palsgrove soils typically are downslope or at a lower elevation. Stronghurst and Traer soils are upslope and on the more level landscape positions. Fayette soils form a biosequence with the Tama soils which have mollic epipedons and the Downs soils. They form a drainage sequence with the somewhat poorly drained Stronghurst and the poorly drained Traer soils. Permeability is moderate.
Surface runoff is medium to rapid.
Depth to an intermittent water table is greater than 6 feet. The less sloping areas are commonly cropped to corn, soybeans, small grains, and legume hays. The steeper slopes are used for pasture or woods and pasture. They are extensive. Fayette County, Iowa, 1919.
