  rdf:value "Gleysols comprise soils saturated with groundwater for long enough periods to develop reducing conditions resulting in gleyic properties, including underwater and tidal soils. This pattern is essentially made up of reddish, brownish or yellowish colours at aggregate surfaces and/or in the upper soil layers, in combination with greyish/bluish colours inside the aggregates and/or deeper in the soil. Many underwater soils have only the latter. Gleysols with a thionic horizon or hypersulfidic material (acid sulfate soils) are common. Redox processes may also be caused by upmoving gases, like CO2 or CH4. Common names for many Gleysols are Gley (former Soviet Union), Gleyzems (Russia), Gleye, Marschen, Watten and Unterwasserböden (Germany), Gleissolos (Brazil) and Hydrosols (Australia). In the United States of America many Gleysols belong to Aquic Suborders and Endoaquic Great Groups of various Orders (Aqualfs, Aquents, Aquepts, Aquolls, etc.) or to the Wassents."@en ;
