Terric Fibric Humisol (TFI.H)
Common horizon sequence: Of or Oh, Oh, Of, C, Oh
Soils of this subgroup have the general properties specified for the Organic order and the Humisol great group. They differ from Typic Humisols by having both a terric layer (an unconsolidated mineral layer at least 30 cm thick) beneath the surface tier and a subdominant fibric layer thicker than 12 cm within the control section. They may also have mesic, cumulic or limnic layers but lack a hydric layer.
