Abstract

Both red fescue cultivars germinated satisfactorily, although the laboratory experiment suggested restricted root development in the non-tolerant cultivar. Both experiments, however, showed that the overall shoot growth and cover of the non-tolerant cultivar were not affected. In fact, in the field experiment the non-tolerant cultivar performed better than the metal tolerant cultivar and showed no pathological symptoms of metal toxicity after 12 months. The advantages of using wood pulp as a mulch were clearly demonstrated. Application of an alginate stabilizer had no benefit. Use of carefully selected non-tolerant cultivars in the revegetation of such calcareous metalliferous wastes is possible, even where the Zn content is as high as 1%. -from Authors
