In soil taxonomy, a type of soil that has features indicating it is saturated to near the surface for a significant portion of the growing season.

These soils have stagnant water on the soil surface and/or can be saturated in some part of the upper 0.5 m of the profile, more or less continuously for 2 to 3 months. In this condition, the soil is free of dissolved oxygen. Gley (bluey-grey) colours are often an indication of prolonged saturation. The definition is used as a Suborder distinction for Podosols and Vertosols in the Australian Soil Classification ( Isbell, 1996).
