These are the competing Fayette , Frankville , Nasset , and Palsgrove series and the Nordness and Sogn series. Nordness and Sogn soils have lithic contacts within 20 inches. Palsgrove, Frankville, and Nasset soils may be on similar landscape positions as Dubuque soils but generally Palsgrove and Nasset soils are at higher elevations or are upslope from Dubuque soils. Fayette soils are upslope and usually at higher elevations than Dubuque soils. Dubuque soils typically are upslope from Nordness and Sogn soils.
Permeability is moderate in the upper part of the solum and slow in the clayey layer.
Surface runoff is medium to very rapid. The less sloping areas are used for cultivated crops. Corn, soybeans, small grains, and legume hays are grown. The more sloping areas are commonly used for pasture and woodland. Native vegetation was deciduous trees.
