These are the Balmorhea , Dalby , Hodgins , Phantom , Pima , Reagan , Reakor , Redona , Toyah , and Upton series. Balmorhea, Hodgins, Pima, Reagan, Reakor, and Toyah soils have less than 35 percent clay and do not have cracks and gilgai. Phantom soils do not have slickensides. Upton soils have a petrocalcic horizon at depths of less than 20 inches and have less than 35 percent clay. All associated soils, except Upton, are in similar positions on the landscape.
Upton soils are in higher position on footslopes and convex ridges.
Moderately well drained. Permeability is very slow. Runoff is negligible on slopes less than 1 percent and high on slopes from 1 to 3 percent. The soil ponds water for 2 to 7 days following high intensity rains, mainly during July through October. Irrigated cropland and native rangeland.
