Evaluation of substrate and amendment materials for soil reclamation at a diamond mine in the Northwest Territories, Canada.
Mine waste materials with potential for use in soil construction at a diamond mine in the Northwest Territories were evaluated to address physical and chemical limitations for plant establishment, growth and development. Substrates were glacial till, gravel, processed kimberlite, and 50:50 and 25:75...
