The subtype Moist Mor develops in soils with a low base saturation and under the long-term impact of stagnant water or groundwater significantly affecting the properties of the mineral topsoil and the organic surface layers. At these sites, poorly decomposable types of litter prevail. The Owsh horizon is smeary when moist or wet, but breakable. In late winter and spring, standing water is frequently found on the soil surface. The Moist Mor is typified by the following characteristics:

• Ol horizon or Owl horizon and Of horizon or Owf horizon are present and
• Owsh horizon is present; and
• overlying a hydromorphic topsoil horizon (A horizon with redoximorphic features).
