     Pedocals are highly alkaline (high pH readings) soils with little or no humus and are formed in arid regions where subsurface evaporation of water crystallizes as calcium or lime deposits. Alkali soils are also pedocals, with a salt content high enough to kill plants. They are found in some southwestern states of the United States.
