Acrisol
Template:Short description Template:Infobox soil
An Acrisol is a Reference Soil Group of the World Reference Base for Soil Resources (WRB).[1] It has a clay-rich subsoil. It is associated with humid, tropical climates, such as those found in Brazil, and often supports forested areas.[2] In the USDA soil taxonomy,[3] Acrisols correspond to the Humult, Udult, and Ustult suborders of the Ultisols and also to Oxisols with a kandic horizon and to some Alfisols.[4] Acrisol's 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 the climate allows, include tea, rubber tree, oil palm, coffee and sugar cane.[4]
