Aridisols
Aridisols
Aridisols (pronounced: a-rid-i-sols, from Latin aridus meaning "dry" and solum meaning "soil") are a type of soil used in the USDA soil taxonomy. Aridisols are found in arid regions of the world, where the climate does not allow for much vegetation growth.
Characteristics
Aridisols are characterized by a lack of moisture, which inhibits the leaching process. This results in the accumulation of salts, gypsum, and/or calcium carbonate in the soil profile. They often have a light color due to the lack of organic matter.
Suborders
Aridisols are divided into several suborders, including:
- Argids: These have a significant accumulation of clay in the subsoil.
- Calcids: These are characterized by a significant accumulation of calcium carbonate.
- Gypsids: These have a significant accumulation of gypsum.
- Salids: These are characterized by a significant accumulation of salts.
Distribution
Aridisols are found in many parts of the world, including the southwestern United States, northern Mexico, central Asia, and northern Africa. They cover about 12% of the Earth's ice-free land area.
Use
Despite their arid conditions, Aridisols can be used for agriculture with the help of irrigation. However, care must be taken to prevent the buildup of salts in the soil, which can be harmful to crops.
