Gleysol - Wikipedia
Gleysol. A gleysol or gley soil is a hydric soil that unless drained is saturated with groundwater for long enough to develop a characteristic gleyic colour pattern. The pattern is essentially made up of reddish, brownish, or yellowish colours at surfaces of soil particles and/or in the upper soil horizons mixed with greyish/blueish colours ...
Gleysol | Wetland Soil, Hydromorphic, Clayey | Britannica
soil. Gleysol, one of the 30 soil groups in the classification system of the Food and Agriculture Organization (FAO). Gleysols are formed under waterlogged conditions produced by rising groundwater. In the tropics and subtropics they are cultivated for rice or, after drainage, for field crops and trees. Gleysols found in the polar regions ...
Gleying | Sedimentology and Stratigraphy
Mar 24, 2017 · The image above is an example of gleying in soil. What is gleying? It is when low oxygen soil conditions (such as a high water table) cause iron and manganese to reduce, and make the soil gray. There are some cases where plants grow in soils that have low oxygen, and the roots that go into the gleyed soil provide just enough oxygen so that iron ...

Apr 29, 2024 · Gley soil is the result of consistently waterlogged, iron rich soil, and is often identified by its characteristic bluish-gray or greenish-gray color . Gleying or Gleyzation occurs when iron compounds are reduced by microorganisms in waterlogged, anaerobic conditions. The iron compounds are either removed from the soil completely or segregated ...
Definition of Gleysols. Soils, having gleyic properties within 50 cm from the soil surface; and. 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. having no abrupt textural change within ...

Feb 20, 2021 · The common feature of Gley Soils is the presence of high groundwater or perched water tables and periodically saturated soil conditions. Thus the soils are described as poorly or very poorly drained. Trafficability is limited in most soils when wet and pugging damage by stock is a common risk.
4. Gley Soils. J H Gauld and L A Dawson. The James Huton Institute Email: lorna.dawson@hu on.ac.uk. General characteristics: The essential common feature of poorly draining gley soils is that, under periodic or permanent waterlogging, the subsoil experiences a lack of oxygen within the pore space. Consequently under anaerobic conditions the ...
