This paper is the first to provide chemical, physical, and morphological properties of the soils in the boreal region of Alaska and to demonstrate the dominant effect of landscape attributes in soil formation. This study was conducted to characterize soils and landscape relationships in the boreal forest of Alaska. Sites representing major landform positions and vegetation communities were selected for study. Well-drained, shallow to moderately deep Inceptisols occur on the drier and warmer south aspect slopes with thin (5-9 cm) organic horizons and loamy textures. Poorly drained Gelisols form on wet and cold north aspect slopes and valley floors with thick (18-52 cm) organic horizons and permafrost within 45 to...

Fifty-two soils under black spruce [Picea mariana (Mill.) Britton et al.]-dominated forest communities were examined and assessed for their organic C (OC) stores in relation to soil characteristics. Study sites were located on a variety of parent materials, landscape positions, and drainage conditions. Results indicate that soils at most sites were weakly developed, commonly with organic (O) horizons ranging from 3 to 39 cm (≥100 cm occasionally). Organic C stores tended to increase as drainage changed from somewhat excessive and well to very poorly drained (average to 1 m: 12.6–50.9 kg OC m-2, respectively). The lowest OC store for an individual site was 7.1 kg OC m-2 in a well-drained soil on an outwash plain...
