Aridisols (from Latin aridus, "dry") are CaCO3-containing soils of arid regions that exhibit at least some subsurface horizon development. They are characterized by being dry most of the year and limited leaching.
Histosols (from Greek histos, "tissue") are soils that are composed mainly of organic materials. They contain at least 20-30% organic matter by weight and are more than 40 cm thick.
Andisols are soils formed in volcanic ash and defined as soils containing high proportions of glass and amorphous colloidal materials, including allophane, imogolite and ferrihydrite. In the FAO soil classification, Andisols are known as Andosols.
