Wacousta soils have a thinner A horizon. Very poorly drained. Runoff is negligible. Permeability is moderately slow. Where drained they are cultivated to corn, soybeans, and small grain.
Native vegetation is water tolerant grasses and sedges.
The differences between the Okoboji and Peotone soils are not clear. Peotone soils have a stronger grade of structure, formed in materials containing much more illite and presumably would have more illite in the sola. Peotone soils receive mean annual precipitation of 35 to 45 inches in contrast to about 30 inches for the Okoboji soils.
