Peatland Vascular Plant Leaf N Concentrations (10 Species) From Leaves Collected From N-Addition Plots in an Alberta Peatland, 2011-2015
Development of the oil sands has led to increasing atmospheric N deposition, with values as high as 17 kg N ha -1 yr -1 ; regional background levels <2 kg N ha -1 yr -1 . Bogs, being ombrotrophic, may be especially susceptible to increasing N deposition. To examine responses to N deposition, over...
