Acrisol | Soil Classification, Clay Content & Texture | Britannica
Acrisols are defined by the presence of a subsurface layer of accumulated kaolinitic clays where less than half of the ions available to plants are calcium, magnesium, sodium, or potassium and also by the lack of an extensively leached layer below the surface horizon (uppermost layer).
Acrisol - Wikipedia
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]

Acrisols - ISRIC
Acrisols occur dominantly in the wetter parts of the tropics and subtropics and the warm temperate regions in relatively young landscapes.
Acrisols are found on acid rocks, mostly of Pleistocene age or older. They are most extensive in South-east Asia, the southern fringes of the Amazon Basin, the southeastern USA and in both east and west Africa. There are approximately 1000 million hectares of …
Acrisol - an overview | ScienceDirect Topics
An Acrisol is a type of soil that is characterized by having an argic horizon in the subsurface, found in hilly landscapes within the humid subtropical ecozone. It has distinct physical, chemical, and mineralogical properties that differentiate it from other soils like Alisols.
