This soil is formed in a loess parent material with clay contents ranging from 16% in the Ap horizon to 59% in the argillic Bt horizon. There is an abrupt increase in clay across the E-Bt horizon boundary.

These are relatively fertile soils because of the high base saturation. However, the clay-rich subsoil causes these soils to become saturated with water during the winter and spring months of the year, creating problems for their use and management. With artificial drainage, these soils are primarily used for agricultural production, with corn, soybeans, and sorghum being the major crops.
