Distribution
Regional Distribution of Plinthosols
Softer plinthosols are common in the wet tropics, including in the eastern Amazon basin, the central Congo basin and parts of Southeast Asia. Dryer areas, including the Sudano-Sahelian zone, Southern African savannah, the Indian subcontinent, and parts of Southeast Asia and northern Australia feature mostly harder pisoliths and petroplinthite.
