An Acrisol is a Reference Soil Group of the World Reference Base for Soil Resources (WRB). It has a clay-rich subsoil and is associated with humid, tropical climates, such as those found in Brazil, and often supports forested areas.[1] Acrisols correspond to the Aquult, Humult, Udult and Ustult sub-orders of Ultisols in the USDA soil taxonomy and also to Oxisols with a kandic horizon and some Alfisols.[2] The Acrisols low fertility and toxic amounts of aluminium pose limitations to its agricultural use, favouring in many places its use for silviculture, low intensity pasture and protected areas. Crops that can be successfully cultivated, if climate allows, include tea, rubber tree, oil palm, coffee and sugar cane.[2]
