Udorthent and landscape KR
Soil profile: A representative soil profile of very deep, excessively drained, disturbed soils in Korea.
Landscape: These Udorthents are in valleys. They formed from cut and fill materials from the surrounding uplands.
Udorthents are the Orthents of cool to hot, moist regions. They have a udic moisture regime and a temperature regime warmer than cryic. Generally, they are acid to neutral. Slopes generally are moderate to steep but are gentle in a few areas. Udorthents commonly occur in areas of very recently exposed regolith, in areas of weakly cemented rocks, or in areas of thin regolith over hard rocks.
Many of the gently sloping soils are the result of earth-moving activities. The vegetation is commonly a deciduous forest, or the soils are used as pasture. Udorthents are extensive soils on steep slopes in the humid parts of the United States.
Orthents are primarily Entisols on recent erosional surfaces. The erosion may be geologic or may have been induced by cultivation, mining, or other factors. Any former soil that was on the landscape has been completely removed or so truncated that the diagnostic horizons for all other orders do not occur. A few Orthents are in areas of recent loamy or fine eolian deposits, Orthents occur in any climate and under any vegetation. They are do not occur in areas that have aquic conditions or a high water table or on shifting or stabilized sand dunes.
