The Gays River mine tailing revegetation study
AbstractThe Gays River (NS) lead-zinc mine ceased operations in 1982. Seven ha of calcereous mine tailings were left which required stabilization. The tailings, variable in physical composition with depth, were devoid of organic matter, N and P. A potting experiment using the tailings, with and without fertilizer, established 6 plant species which could potentially revegetate the tailing site. Experimental plots (24) were established on the tailings in May 1983 using the same 6 species and 2 indigenous species (alder (Alnus rugosa) and bulbrush (Scirpus americanus Pers.)). The plots were maintained through June 1985; plant yield and tissue analysis for macro- and micronutrients followed each cutting or sampling data. The final recommendations for reclamation were to drill in alfalfa (Medicago sativa L.) and red clover (Trifolium pratense L.) seeds, cut and fertilize annually with 800 kg ha-1 of 12-24-24 or transplant couchgrass (Agropyron repens) and fertilize periodically with 12-24-24.
