Toolik Lake E. Vaginatum Root Mineral Nutrition. Version 1.0
Soil cores of 5cm diameter and 20cm depth were taken at approximately 2 week intervals during the 2001 growing season. Three age classes of Eriophorum vaginatum roots (gray (senesced), brown (suberized) and white (active)) were extracted from the cores. Following extraction, cores were cut into 5 4c...
