Permeability is moderately slow. In the undrained condition these soils have an apparent water table as much as 1 foot above the surface at some time between January and June in most years. Where drained, the water table is 1 foot above the surface to 1 foot below at some time between March and June in most years. Most areas are used for cultivated crops. Corn and soybeans are the principal crops.
Native vegetation is marsh grasses and sedges.
Southern and central Illinois and Minnesota. Shelby County, Illinois, 1932. Some areas on bottom lands that flood frequently for long periods are within the defined limits of the Shiloh series because the undrained condition and ponding restrictive feature give the desired interpretations. The differentiae needed to clearly separate the Shiloh series from Peotone series are not well defined in terms of soil properties. Peotone soils were established nearly 20 years after the Shiloh series was established.
