Fera Luvic Gleysol (FE.LG)
Common horizon sequence: LFH or O, Ah, Aeg, Btgf or Bfg and Btg, Cg
These soils have the general properties specified for the Gleysolic order and the Luvic Gleysol great group. They also have either a Bgf horizon at least 10 cm thick as well as a Btg horizon or a Btgf horizon. A Bgf or Btgf horizon contains accumulated hydrous iron oxide (dithionite extractable), which is thought to have been deposited as a result of the oxidation of ferrous iron. It usually has a high chroma and is commonly a horizon with a concentration of rusty mottles. Fera Luvic Gleysols lack all the following: an Ah or Ap horizon diagnostic of Humic Luvic Gleysols, a solonetzic B horizon, and a fragipan.
Note: Diagnostic horizons are underlined.
