Orthic Eutric Turbic Cryosol (OE.TC)

Common horizon sequence: Om, Bmy, BCy, Cgy, Omy, Cz

These Turbic Cryosols have a relatively high degree of base saturation, as indicated by their pH. They are identified by the following properties:

1. These soils have a Bmy horizon and may have a Bm horizon less than 10 cm thick.
2. The horizons are strongly disrupted by cryoturbation. Tongues of mineral and organic horizons, organic and mineral intrusions, and oriented stones commonly occur.
3. These soils have a pH (0.01 M CaCl₂) of 5.5 or greater in some or all of the B horizons.
4. The surface horizons are not strongly gleyed, but there is usually a gleyed horizon immediately above the permafrost table.

Orthic Eutric Turbic Cryosols have a Bmy horizon and subsurface organic (Omy, Ohy) or organic-rich, mineral horizons (Ahy). Surface organic horizons up to 15 cm thick, moder Ah horizons, and Bm horizons less than 10 cm thick may occur.

Note: Diagnostic horizons are underlined.
