This area has many kinds of upland soils but most are deep, light-colored, acid sands and loams over loamy and clayey subsoils. Loamy soil also contains particles of nutrient-rich clay (besides sand and silt), which enhances soil retention and balances the moisture content of the soil. The color of bare soil varies, and that variation is related to soil quality. This area lies between the Western Cross Timbers and the Rolling Plains. When settlers first arrived in the Midwest, it was everywhere, created from centuries of accumulated prairie grass. This soil is characterized by its silty, clay and loam textures.
