Reference soil Greece 15: Fluvisol

GR015

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.

Distribution of Fluvisols (rough estimation supplied by soilgrids)

Reference soil GR015: Fluvisols

Diagn.criteria: Org C decreases irregularly with depth. Crusting occurs during dry months. Very few rounded gravels at surface. Publ.: Calcaric Fluvisols: An example from southern Greece. MSc thesis N. Danalatos Wageningen 1985
