Abstract

Investigations were conducted to determine the feasibility of establishing plant cover on copper tailing located in Central Chile (32ƒ40'S, 71 OlO'W). Chemical analysis of the tailings indicated low concentrations of major nutrients (e.g., phosphorus and nitrogen) DQGan excess of normally trace metals. A number of plant species which were sown or planted on the tailings became established. Application of fertilizers increased shrub growth compared to non-fertilized plants but had an inhibiting effect on seed germination.
