Terric Humic Mesisol (THU.M)

Common horizon sequence: Of, Om or Oh, Om, Oh, C, Om

Soils of this subgroup have the general properties specified for the Organic order and the Mesisol great group. They differ from Typic Mesisols by having both a terric layer (an unconsolidated mineral layer at least 30 cm thick) beneath the surface tier and a subdominant humic layer thicker than 25 cm within the control section. These soils may also have fibric, cumulic, or limnic layers but lack a hydric layer.

Note: Diagnostic horizons are underlined.
