ACID AND ALUMINUM TOXICITY AS RELATED TO STRIP-MINE SPOIL BANKS IN WESTERN PENNSYLVANIA

Special Research Report SR-72 Although the reclamation of strip-mined areas is required in Pennsyl- vania, a substantial number of stripped areas cannot be revegetated successfully by present methods. These spoils are highly acid and may contain toxic substances. A review of published reports on acid-spoil characteristics and an investigation on the chemical properties of selected toxic spoils in western Pennsylvania revealed that such spoils are low in several essen- tial elements and high in exchangeable hydrogen and aluminum. Because of the reported toxicity of both hydrogen and aluminum to plants, these el~ments were chosen for further study. A series of experiments was designed to evaluate the effects of various concentrations of hydrogen and aluminum on tree seedlings of selected species growing in nutrient- solution cultures.
