Characterizing organic matter and nutrient status in smelter-affected soils
Forest vegetation dieback has occurred around Flin Flon, Manitoba and Creighton, Saskatchewan since the beginning of the 20th century, when sulphide ore smelting began in the area. In order to support future revegetation ...
The Depth Distribution of Organic Carbon in Mineral Cryosols at Two Sites in the Canadian Arctic
