摘要：

Minimal Podzol (Pergelic Cryopsamments), Arctic Brown (P. Cryorthents), and Tundra (P. Cryaquepts) soils occur along moist fiords and Polar Desert (P. Cryorthents) soils occur in the more xeric uplands. Polar Desert soils have undergone acid leaching but maintain some features of Polar Desert soils in the high arctic, above ca. 75oN latitude. Most of the soils are extremely to strongly acid and contain low amounts of organic matter, exchangeable bases, extractable phosphorus, and clay. Soil properties most related to age are depth of oxidation, maximum percent free iron, color of the surface mineral horizon, and kaolinite/mica ratio in the clay-size fraction. -from Author
