PEDOGENESIS IN A SUBARCTIC ENVIRONMENT

Accumulation of organic matter on the soil surface and subsoil pedogenesis are examined within a subarctic environment. Surface organic matter varied from 0.26 kg organic C m-2 beneath a recently exposed beach shrub to 25.8 kg organic C m-2 in a peaty depression. Generally, highest amounts were recorded beneath the deciduous and spruce forests and lowest amounts beneath the open spruce-lichen woodlands. Leaching and podzolization are the dominant pedogenetic processes. Podzols are best developed on quartzite-derived material, with Ae and Bf horizons up to 10 cm thick; these horizons are weak or nonexistent in soils developed on gneiss. Differential dissolution techniques show that there has been translocation of relatively large amounts of iron, aluminum, and organic matter between horizons. Most soils examined fall into the Orthic Humo-Ferric Podzol or Degraded Dystric Brunisol subgroups of the Canadian classification scheme.
