Gelisols are an order in USDA soil taxonomy. They are soils of very cold climates which are defined as containing permafrost within two meters (6 ft 7 in) of the soil surface. The word "Gelisol" comes from the Latin gelare meaning "to freeze", a reference to the process of cryoturbation that occurs from the alternating thawing and freezing ...
Wetness is the main limitation on agriculture of virgin gleysols; [2] these are covered with natural swamp vegetation and lie idle or are used for extensive grazing. Farmers use artificially-drained gleysols for arable cropping, dairy farming and horticulture. Gleysols in the tropics and subtropics are widely planted with rice.
A vertisol is a Soil Order in the USDA soil taxonomy [1] and a Reference Soil Group in the World Reference Base for Soil Resources (WRB). [2] It is also defined in many other soil classification systems. In the Australian Soil Classification it is called vertosol. [3] The natural vegetation of vertisols is grassland, savanna, or grassy woodland ...
Expansive clay is a clay soil that is prone to large volume changes (swelling and shrinking) that are directly related to changes in water content. [1] Soils with a high content of expansive minerals can form deep cracks in drier seasons or years; such soils are called vertisols.
In both the World Reference Base for Soil Resources (WRB) [1] and the USDA soil taxonomy, [2] a Histosol is a soil consisting primarily of organic materials. They are defined as having 40 centimetres (16 in) or more of organic soil material starting within 40 cm from the soil surface.
The main processes of soil formation of oxisols are weathering, humification and pedoturbation due to animals. These processes produce the characteristic soil profile.They are defined as soils containing at all depths no more than ten percent weatherable minerals, and low cation exchange capacity.
