Isohumosol CN
A Cryi-Ustic Isohumosol and landscape. These soils mainly distribute in the vertical zones in mountain valleys of eastern Qilian Mountain in Qinghai-Tibet Plateau, and in the continental cool-temperate monsoon climate zone in the Greater Khingan Mountains, Heilongjiang Province. Parent materials are quite complicated, including slope deposits derived from sandstone, siliceous slate and granite, and also loess, red clay as well as diluvium, and alluvium. The annual precipitation is 350-650 mm. The vegetation is mainly meadow and shrub, and growing Kobrecia humilis, and Poa annua, etc. Those soils in northeast China are mostly cultivated as dry-farmland. A fairly thick humus horizon presents due to the accumulation of large amount of organic matters. Soil development is not affected by underground water. (Photos and notes courtesy of China Soils Museum, Guangdong Institute of World Soil Resources; with revision.)
In Chinese Soil Taxonomy, Isohumosols have deep accumulation of humus under cool temperature. In Soil Taxonomy these soils are Mollisols.
