Poorly Drained Soils with Permafrost in Interior Alaska
Abstract Physical, chemical, and mineralogical properties are presented for five soils with permafrost in interior Alaska. The soils are shallowly thawed, with permafrost usually at 60 cm or less, and with a thick accumulation of organic matter, usually about 25 cm deep, over a gleyed mineral soil....
