Plinthosol
Soils having either a petroplinthic horizon within 50 cm from the soil surface, or a plinthic horizon which either starts within 50 cm from the soil surface, or within 100 cm from the soil surface if it underlies an albic horizon or a horizon with stagnic properties.
Distribution of PLINTHOSOLS
Plinthosols occur mainly in the moist tropical regions in low-lying positions where iron from the soil and adjacent uplands is accumulating.
