Okee soils are on ground and end moraines and drumlins. Slope gradients are dominantly 2 to 6 percent but range from 1 to 25 percent. They formed in wind or water deposited sandy deposits and the underlying glacial till. F. Mean annual precipitation is about 30 inches. These are the competing Mecan , Puchyan , and Wyocena soils and the Chelsea , Kidder , and Plainfield soils.
Puchyan soils occupy slightly lower positions in the landscape.
Chelsea, Kidder, Mecan, Plainfield, and Wyocena soils are on similar landscape positions. Kidder soils do not have sandy textures within the solum. Chelsea and Plainfield soils are in a sandy family and do not have glacial till in their sola. Wyocena soils have thinner sand or loamy sand overlying the argillic horizon. Some areas are cropped to corn, small grain, and hay.
