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 in depth. This fertile surface horizon, called a mollic epipedon, is the defining diagnostic feature of Mollisols.
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 - 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.
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.
Overview of Mollisols in the world: Distribution, land use ...
2012年1月1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 occur in a range of climatic zones; they are most commonly found in subhumid and semi-arid areas, less frequently in humid areas. Temperature regimes range from cryic to isohyperthermic. There are eight suborders of Mollisols, six of which are based on soil climate characteristics (Soil Survey Staff, 2014).

The Mollisol order takes its name from the Latin word mollis, meaning soft. These mineral soils have developed on grasslands, a vegetation that has extensive fibrous root systems. The topsoil of Mollisols is characteristically dark and rich with organic matter, giving it a lot of natural fertility.
