Herbert and Odell soils are on similar landform positions nearby. Herbert soils lack a mollic epipedon. Odell soils formed in a thinner mantle of loess. Somewhat poorly drained. The potential for surface runoff is slow or medium.
Permeability is moderate in the solum and moderately slow in the underlying material.
An intermittent perched water table is at a depth of 1.0 foot to 2.0 feet at some time between January and May in most years. Most areas are cultivated. Corn, soybeans, small grain, and meadow are the principal crops. Native vegetation is tall prairie grasses. Boone County, Illinois, 1935.
