Reference soil Canada 17: Fluvisol

CA017

Fluvisols typically are young soils in alluvial, deltaic, lacustrine, or marine deposits, and occur all over the world.

Characteristics

Soils having fluvic soil material starting within 25 cm from the soil surface and continuing to a depth of at least 50 cm from the soil surface. They have no diagnostic horizons other than a histic, mollic, ochric, takyric, umbric, yermic, salic, or sulfuric horizon.
