Gleysols are wetland soils, which in the natural state are continuously water‐saturated within 50 cm of the surface, for long periods of time. Reduction of Fe and Mn leads predominantly to grayish hues in the profile below the water table. This article is based on the descriptions in FAO (2001).

Connotation. Soils with clear signs of excess wetness; from R. gley, mucky mass.

Synonyms. Gleysols are equivalent to ‘gleyzems’ and ‘meadow soils’ (Russia), ‘aqu‐’ suborders of entisols, inceptisols and mollisols (Soil Taxonomy), ‘Gley’ (Germany). ‘Groundwater soils’ and ‘hydromorphic soils’ are commonly used general terms.

Definition. Gleysols are defined by FAO ( 2001) as
  1. 1.

    having gleyic properties within 50 cm from the soil surface; and

     
  2. 2.

    having no diagnostic horizons other than an anthraquic, histic, mollic, ochric, takyric, umbric, andic, calcic, cambic, gypsic, plinthic, salic, sulfuric or vitric horizon within 100 cm from the soil surface.

     
  3. 3.

    having no abrupt textural change within...
