MLRA 91 - Wisconsin and Minnesota Sandy Outwash Minnesota and Wisconsin 52,780 km2 (20,380 mi2)

Soils:
Most of the soils are Psamments. They are deep and coarse textured and have mesic and frigid temperature regimes and mixed mineralogy. Well drained and moderately well drained, nearly level and rolling Udipsamments (Plainfield, Coloma, Brems, Menahga, and Zimmerman series) and somewhat poorly drained, nearly level and rolling Udipsamments (Morocco and Meehan series) are on sandy outwash plains or on sandy till uplands. Humaquepts (Newton series) and Haplaquolls (Isanti series) are underlain by sandy drift on wet lowlands. Borosaprists (Seeleyville and Lupton series) and Borohemists (Rifle and Greenwood series) in deeper depressions formed in organic residue from plants. Nearly level and gently rolling Argiudolls (Dakota series), Hapludolls (Dickman, Burkhardt, Sparta, and Dickinson series), and Hapludalfs (Tell, Meridian, and Wyocena series) formed on outwash and till uplands that have a loamy covering over the sandy drift. Udifluvents are on flood plains of rivers and streams.
