Abstract
Effects of chemical amendments on properties of two sodic mine spoils (sandstone and shale origins) and on growth of two range plants (alkali sacaton and fourwing saltbush) were studied in search of promising revegetation methods. The chemical amendments included applications of concentrated sulfuric acid, gypsum and phosphorus. On the shale spoil, these chemicals were applied in combination with physical amendments consisting of sand mulching, sand top-dressing, or sand incorporation. The sand used for the physical amendment was aeolian sand, which is locally available in the mine area. Laboratory water penetration tests and greenhouse plant growth tests were performed. Results indicate the following amendments to be promising: for sandstone-based spoils, sulfuric acid treatment, gypsum plus phosphorus application or phosphorus fertilization alone, depending on severity of sodium problems; for shale-based spoils, acid treatment can best be combined with either sand mulching, sand top-dressing, or sand incorporation. Gypsum plus phosphorus treatment in combination with sand top-dressing may provide an alternative treatment. 9 references.
