Aridisols
Aridsols are soils that develop in very dry environments. The main characteristic of this soil is poor and shallow soil horizon development. Aridsols also tend to be light colored because of limited humus additions from vegetation. The hot climate under which these soils develop tends to restrict vegetation growth. Because of limited rain and high temperatures soil water tends to migrate in these soils in an upward direction. This condition causes the deposition of salts carried by the water at or near the ground surface because of evaporation. This soil process is of course called salinization.
Aridisols are the dry soils of deserts ( the root arid or id comes from the Latin aridus for dry). They do not receive enough rain to permit normal agriculture. They may have a clay enriched subsoil and /or cemented to non cemented deposits of salts or carbonates. Salinization, or salt buildup is the greatest danger in using Aridisols for irrigated agriculture. Most areas of true desert are retained as wilderness though the margins may be used for grazing.
