Reference soil Suriname 04: Arenosol

SR004

Arenosols occur over large areas in Africa, central and western Australia, the Middle East and central China. Smaller areas are found along coastlines all over the world.

Characteristics

Soils with a loamy sand or coarser texture either to a depth of at least 100 cm from the soil surface, or to a (petro-)plinthic or salic horizon between 50 and 100 cm from the soil surface. They contain less than 35 percent (by volume) rock fragments or other coarse fragments within 100 cm from the soil surface and have no diagnostic horizons other than an ochric, yermic or albic horizon, a (petro-)plinthic or salic horizon below 50 cm from the soil surface, or an argic or spodic horizon below 200 cm below the soil surface.
