Humic Luvic Gleysol (HU.LG)
Common horizon sequence: LFH or O, Ah, Aeg, Btg, Cg
These soils have the general properties specified for the Gleysolic order and the Luvic Gleysol great group. They have, in addition, a mineral-organic surface horizon that meets the requirements of the Ah or Ap horizon of Humic Gleysols. Thus, the Ah horizon must be at least 10 cm thick and the Ap horizon must be at least 15 cm thick, contain at least 2% organic carbon, and have a darker color than the underlying horizon. Humic Luvic Gleysols have neither a solonetzic B horizon nor a fragipan, but they may have a Bgf horizon.
