Mollisol - Wikipedia
Mollisol is a soil type which has deep, high organic matter, nutrient-enriched surface soil (A horizon), typically between 60 and 80 cm (24-31 in) in depth. This fertile surface horizon, called a mollic epipedon, is the defining diagnostic feature of Mollisols.
Mollisols - Natural Resources Conservation Service
The central concept of Mollisols is that of soils that have a dark colored surface horizon and are base rich. Nearly all have a mollic epipedon. Many also have an argillic or natric horizon or a calcic horizon. A few have an albic horizon. Some also have a duripan or a petrocalic horizon.
Mollisol | Grassland, Clay Soil & Humus | Britannica
Mollisols are characterized by a significant accumulation of humus in the surface horizon, or uppermost layer, which is almost always formed under native grass vegetation. They are highly arable soils used principally for growing grain.
Mollisols | Soil & Water Systems | University of Idaho
Mollisols (from Latin mollis, "soft") are the soils of grassland ecosystems. They are characterized by a thick, dark surface horizon. This fertile surface horizon, known as a mollic epipedon, results from the long-term addition of organic materials derived from plant roots.
Mollisol - an overview | ScienceDirect Topics
Mollisols are naturally fertile soils with a thick, friable, very dark coloured, organic rich, surface layer (mollic epipedon). Soils literature for 20 South Pacific island countries was examined for information on Mollisols; of these countries, 16 had confirmed Mollisols.
2021年2月15日 · Mollisols are often recognized as inherently productive and fertile soils. They are extensively and intensively farmed, and increasingly dedicated to cereals production, which needs significant inputs of fertilizers and tillage. Mollisols are also important soils in pasture, range and forage systems.
Mollisol - an overview | ScienceDirect Topics
Mollisols are a type of soil characterized by the presence of a thick, dark, humus-rich surface horizon. These soils are found in grassland regions and are highly fertile, making them ideal for cultivation without irrigation.
Chapter 4 Mollisols - ScienceDirect
1983年1月1日 · Mollisols are mineral soils that have a mollic epipedon (dark-colored surface horizon with greater than 50 % base saturation as determined by the ammonium-acetate method) or have a surface horizon that after mixing to a depth of 18 cm meets all requirements for a mollic epipedon except thickness.

Key Characteristics: Mollisols – Grassland Soils. Dominant soil order of the North American Great Plains region. Large areas of Mollisols are also found in Eastern Europe, Russia, China, and South America. Generally very fertile for plant growth due to clay and organic matter content. Considered to be among the most fertile soils on Earth.
