COMPETING SERIES: These are the Ashdale, Broadwell, Dinsdale, Elkhart, Elmont, Healing, Lycurgus, Malcolm, Meadowbank, Ogle, Osco, Parkway, Plano, Proctor, Richwood, Tama, Tecumseh, Toddville, Wakenda, Waupecan, and Wiota series.. Ashdale and Elmont soils have a paralithic contact within a depth of 60 inches. Elkhart and Parkway have carbonates within a depth of 60 inches. Dinsdale, Meadowbank, Proctor, Richwood, Tecumseh, Toddville, and Waupecan soils have more than 50 percent sand in lower part of series control section. Healing soils do not have redoximorphic features. Malcolm and Ogle soils formed in loess over glacial till. Broadwell, Plano, Tama, Wakenda, and Wiota soils average more than 27 percent clay in the particle size control section. Osco soils have redoximorphic features above a depth of 40 inches and saturation between a depth of 4 and 6 feet.
GEOGRAPHIC SETTING:
Parent Material: Silty slope alluvium

water table at a depth of 3.5 to 5 feet for 1 month or more per year at some
time during the period October to June in 6 or more out of 10 years.
Permeability: Moderate
Runoff: Low to medium
USE AND VEGETATION: These soils are used for cropland. Common crops are corn, hay, and small grain.
DISTRIBUTION AND EXTENT: Southwestern Wisconsin. MLRA 105. This series is of small extent.
MLRA OFFICE RESPONSIBLE: St. Paul, Minnesota
SERIES PROPOSED: Richland County, Wisconsin, 2002. Name comes from a road in the town of Gotham in Richland County.
