Isohumosol and landscape CN
A Pachi-Ustic Isohumosol and landscape. These soils refer to a group of Ustic Isohumosols that have a mollic epipedon with a thickness at least 50cm. Topographically, their distributing areas are mainly low mountains, hills as well as high and low plains. Parent materials are diversified residual and slope deposits derived from granite, basalt, sandy mudstone and tertiary red clay, diluvial-alluvial deposits, loess as well as loess-like or sandy sediments. With a semi-humid to semi-arid climate, those areas have an annual precipitation 300-450mm. Vegetation is meadow composed of Sanguisorba officinalis, Vica venosa, and diversified grasses , as well as meadow-steppe composed of Aneurolepidum chinensis and diversified grasses. Calcium carbonate was leached to deeper parts of the profile. (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.
