Waste for wastelands reclaiming taconite tailings basins with organic amendments.

Abstract: Taconite tailings basins cover 10,500 hectares in northern Minnesota. Since these tailings are primarily quartz and iron oxides, water quality has not been an issue, but establishing vegetation on the coarse fraction of the tailings has been a major problem. Reclamation rules require that (I) percent cover must equal 90% after three to five years (depending on slope and aspect), and (2) vegetation must be self-sustaining after ten years. Typical cover on coarse tailings, even after five years, has ranged from4… Show more

“…After three years municipal solid waste compost produced the highest percent cover (Figure 3). MSW compost has consistently produced successful vegetation in all previous field trials (Eger et al, 1999). Although the percent cover did not quite meet the numeric standard of 90%, the vegetation would be considered acceptable (S. Dewar, personal communication).…”

“…The initial studies were conducted using small plots (2.5m x 4m) that demonstrated the application of organic amendments significantly improved vegetative cover (Eger et al, 1999;McCarthy et al, 1995;Norland et al, 1995Norland et al, , 1993Norland et al, , 1991. Although percent cover generally increased with increasing amounts or organic material, 44.8 mt/ha was selected as a cost effective rate.…”
