These are the Ethel , Immanuel , Stuttgart and Tichnor series. Stuttgart soils, which occur on slightly higher positions are moderately well drained. Tichnor soils, which occur on floodplains, have a combined A and E horizon thickness greater than 24 inches and are in a fine-silty particle size family. Dewitt soils are poorly drained. Runoff is negligible to medium.
Permeability is slow.
The soils are saturated above the clayey subsoil at a depth of 0.5 to 1.5 feet from December through April. Native vegetation was tall prairie grasses and scattered hardwood timber. Most areas of the soils are now cultivated and used for rice, soybeans, and wheat. The series is moderately extensive. These soils were formally mapped in the Crowley series.
