Relationship of Saltbush Species To Soil Chemical PropertiesThe relationship of pure stands of 6 saltbush species to sodium adsorption ratio, electrical conductivity, and alkalinity are documented. The data gathered were obtained while correlating soils to range sites for National Cooperative Soil Surveys. Soil scientists gathered detailed soil information and obtained lab data. Range conservationists correlated the saltbush species to specific soils and by using lab data made a direct relationship to pure saltbush stands. Species ranked from highest to lowest adaptability to SAR, EC, and pH are: mat saltbush (Atriplex corrugata S. Wats.), mound saltbush (A. obovata Moq.), Castle Valley clover (A. cuneata A. Nels.), sickle saltbush (A. falcata (M.E. Jones) Standl.), shadscale (A. confertifolia (Torr. & Frem.) S. Wats.) and fourwing saltbush (A. canescens (Pursh) Nutt.). By knowing the SAR, EC, and pH tolerances of these 6 species, interpretations for inventorying, rating plant community potentials, and applying range improvements will be achieved with greater success.
