Aridisol An order of mineral soils that are found in arid environments. These soils have very little organic matter in their surface horizons, but may contain calcium carbonate or gypsum, and/or soluble-salt accumulations. The order includes infertile alkaline and saline soils of deserts. Except for a few tolerant species, the vegetation is very sparse, making the soil prone to erosion.
