Evaluation of extractable elements in artificial substratum made from sewage sludge: Approach to remediation of degraded land in the Arctic
Abstract The Arctic (or subarctic) is characterized by a harsh climate and nutrient‐poor soil; what makes it even harsher in Monchegorsk (67°51′N and 32°48′E) is that metal pollution originating from the Ni–Cu smelting industry has severely damaged the soil and ground vegetation, resulting in format...
