Soil Regime ProfileEPA Ecoregion 30 (Edwards Plateau)

Edwards Plateau & Hill Country Shallow Limestone

Dominant Soil Order: Mollisols / Inceptisols
Parent Material: Cretaceous Hard Limestone, Dolomite, and Indurated Caliche Beds

The Edwards Plateau and Texas Hill Country regime feature very shallow, stony, dark calcareous clays (Tarrant and Brackett series) mantling dense, bedded Cretaceous limestone and thick, impenetrable caliche hardpans. Topsoil depths are often under 12 inches, with solid limestone bedrock or cemented caliche exposed at the surface. Earthmoving contractors rely heavily on heavy excavators equipped with 5,000-to-10,000 ft-lb hydraulic breakers, rock trenchers, and ripper-equipped D8/D9 dozers. Land clearing involves shearing and mulching dense Ashe juniper (cedar) and using heavy root rakes to separate vegetation from the rocky ground surface without hauling excessive rock to off-site disposal facilities.
