These are the Bertrand , Curran , and Tell soils. The well drained Bertrand soils and the somewhat poorly drained Curran soils form a drainage sequence with Jackson soils. Tell soils are nearby in slightly higher landscape positions than those of Jackson soils where the silty mantle is 20 to 40 inches thick over the sandy alluvium. Moderately well drained. Runoff is slow or medium.
Permeability is moderate in the silty and loamy alluvium and rapid in the sandy alluvium.
These soils have an apparent seasonal high water table at a depth of 3.5 to 6 feet for 1 month or more per year at some time during the period November to May in 6 or more out of 10 years. Most areas are used for cropland. Common crops are corn, small grain, and hay. Some areas are used for woodland and pastureland. Native vegetation is mixed hardwood forest.
