The Permian-age Castile and related Salado formations occupy more than 250,000 hectares in Culberson County, Texas and Eddy County, New Mexico.  Soils derived from these rocks contain large amounts of gypsum and pose special challenges to landusers, and scientists making soil surveys.  The objectives of this presentation are to 1) describe the unique aspects of soils that formed from the Castile formation, 2) identify relationships between soil properties and landforms, parent material origins, and vegetation, 3) discuss land use and management and the information needs of decision-makers, and 4) point out inadequacies in the current standards for describing, classifying, and interpreting these soils.
