Carbon and nitrogen cycling in tundra soils - Churchill

Angela Bedard-Haughn & Maxime Paré
The landscapes were divided into five landform units: (1) upper slope, (2) back slope, (3) lower slope, (4) hummock, and (5) interhummock, which represented a great diversity of Static and Turbic Cryosolic soils including Brunisolic, Gleysolic, and Organic subgroups. Soil gross N mineralization was measured using the 15N dilution technique, whereas soil GHG emissions (N2O, CH4, and CO2) were measured using a multicomponent Fourier transform infrared gas analyzer. Soil organic matter characteristics were determined by...
