'''Aridisols''' (or '''desert soils''') are a soil order in [[USDA soil taxonomy]].<ref>{{cite web | url=http://soils.usda.gov/technical/classification/orders/aridisols.html | title =Aridisols | publisher=USDA-NRCS | access-date=2006-05-14 | archive-url=https://web.archive.org/web/20060509223112/http://soils.usda.gov/technical/classification/orders/aridisols.html| archive-date=9 May 2006 | url-status= live}}</ref> Aridisols (from the Latin ''aridus'', for "dry", and ''solum'') form in an arid or semi-arid climate. Aridisols dominate the [[deserts and xeric shrublands]], which occupy about one third of the Earth's land surface. Aridisols have a very low concentration of [[organic matter]], reflecting the paucity of vegetative production on these dry soils. <br />
Water deficiency is the major defining characteristic of Aridisols. Also required is sufficient age to exhibit [[subsoil]] weathering and development. Limited leaching in aridisols often results in one or more subsurface soil horizons in which suspended or dissolved minerals have been deposited: silicate clays, sodium, calcium carbonate, gypsum or soluble salts. These subsoil horizons can also be [[cementation (geology)|cemented]] by carbonates, gypsum or silica. Accumulation of salts on the surface can result in [[Soil salinity|salinization]].<br />
<br />
In the [[World Reference Base for Soil Resources]] (WRB), most Aridisols belong to the [[Calcisol]]s, [[Gypsisol]]s, [[Durisol]]s and [[Solonchak]]s.<ref>{{Cite web|url = http://www.fao.org/3/i3794en/I3794en.pdf|title = World Reference Base for Soil Resources 2014, Update 2015|author=IUSS Working Group WRB|year = 2015|publisher = World Soil Resources Reports 106, FAO, Rome}}</ref><br />
