An arenosol (AR) can be defined through :
- a texture which is loamy sand or coarser, either :
- to a depth of at least 100 cm from the soil surface
- to a plinthic, petroplinthic or salic horizon between 50 and 100 cm from the soil surface
and :
- less than 35 percent (by volume) of rock fragments or other coarse fragments within 100 cm from the soil surface
and :
- no diagnostic horizons other than an ochric, yermic or albic horizon, or a plinthic, petroplinthic or salic horizon below 50 cm from the soil surface, or an argic or spodic horizon below 200 cm depth
