Profile of aridisol

Aridisols (from the Latin aridus – dry) are soils that occur in climates that are too dry for “mesophytic” plants—plants adapted to neither a too wet nor too dry environments—to survive.

The climate in which Aridisols occur also restricts soil weathering processes. Aridisols often contain accumulations of salt, gypsum, or carbonates, and are found in hot and cold deserts worldwide.

They occupy about 12% of the Earth’s glacier-free land area, including some of the dry valleys of Antarctica.
