The somewhat poorly drained Bennington and Ravenna soils are on slightly higher landscape positions. The very poorly drained Condit soils have more clay in the subsoil and are on similar landscape positions. The very poorly drained Luray and Patton soils and the poorly drained Sebring soils formed in silty lacustrine materials on lake plains. Marengo soils are very poorly drained. The potential for surface runoff is negligible to low.
Permeability is moderate or moderately slow.
The depth to the top of an apparent seasonal high water table ranges from the surface to 1 foot above the surface from November to June in normal years. Most of the Marengo soils have been drained and are used for the production of crops such as corn, soybeans, wheat, oats, and mixed hay. Some areas are pastured. The native vegetation is deciduous swamp forest with elm, red maple, silver maple, pin oak, and ash as dominant species. The series is of moderate extent.
