Primosol and landscape CN
A Geli-Alluvic Primosol and landscape. These soils are mainly in udic and ustic temperate zones with gelic climate condition, permafrost or seasonal frost layers. Distributing areas include broad valley plains, lowlands at footslopes, as well as broad valleys, lake basins, and canyon valleys at northern Qinghai-Tibet Plateau . There are scattered deciduous shrubs and some prairie with low coverage. Very little farming and grazing would be found in those areas. Presenting in soil solum, alluvial beddings vary with parent material types. With finer texture, lake and river sediments lead to better soil moisture regime and more organic matter accumulation, on the other hand, diluvial materials with coarser texture lead to less organic material accumulation. (Photos and notes courtesy of China Soils Museum, Guangdong Institute of World Soil Resources; with revision.)
In Chinese Soil Taxonomy, Primosols are recent soils with no diagnostic horizons or only an ochric epipedon. In Soil Taxonomy these soils are mostly Entisols or some Gelisols.
