Orthic Humic Gleysol (O.HG)

Common horizon sequence: LFH or O, Ah, Bg, Cg

These soils have the general properties specified for the Gleysolic order and the Humic Gleysol great group. Typically, they have a well-developed Ah horizon overlying gleyed B and C horizons. They may have organic surface horizons, an eluvial horizon, and a C horizon that does not have the dull colors and mottling that indicate gleying.

Orthic Humic Gleysols are identified by the following properties:

1. They have an Ah horizon at least 10 cm thick as defined for the great group.
2. They have a B horizon (Bg or Bgtj) at least 10 cm thick.
3. They do not have any of the following: a Btg horizon, a solonetzic B horizon, or a Bgf horizon at least 10 cm thick.

Note: Diagnostic horizons are underlined.
