The Nevin and Wiota soils, though of somewhat coarser texture, are considered as the somewhat poorly and moderately well drained members of the same drainage sequence as the Bremer soils. Ely and Judson soils have less clay in the B horizon. Colo and Zook soils have mollic epipedons more than 36 inches thick and are on bottomlands below the Bremer soils. Nevin and Wiota soils are on higher-lying areas on stream terraces. Ely and Judson soils are on foot slopes above the Bremer soils.
Surface runoff is slow.
Permeability is moderately slow. Commonly used to grow corn, soybeans, small grains and hay. Native vegetation is tall prairie grasses. Bremer soils are in southern and eastern Iowa, northern Missouri, Kansas, and Minnesota. They are of moderate extent.
