Also glei.
[Ukrainian, = sticky bluish clay (see quot. 1963); cogn. w. clay n.]
A blue-grey soil or soil layer in which iron and manganese compounds are reduced through being waterlogged; also, such a soil mottled with brownish oxidized patches as a result of periods of relative dryness. Also gley horizon, gley soil, etc.
1927C. F. Marbut tr. Glinka's Great Soil Groups 36 In the last two groups the ‘Glei’ horizon, developed under the influence of ascending moisture, is often present. 1953H. L. Edlin Forester's Handbk. v. 77 Gleys..are soils that develop where drainage is impeded, so that there is a fluctuating water-table or saturated layer in the soil structure. 1963Birron & Cole tr. Vilenskii's Soil Sci. xxi. 308 The words ‘glei’ and ‘gleification’ were derived from the popular Ukrainian and introduced into scientific terminology in 1905 by G. N. Visotskii. 1969Jrnl. Soil Sci. XX. 207 Failure to distinguish between sulphide-containing and sulphide-free gley soils causes considerable confusion.
Hence ˈgleyed ppl. a., turned into a gley; ˈgleying, gleiing vbl. n., gleiˈzation |gleɪ-|, the formation of a gley.
1934Forestry VIII. 30 The gleyed horizon is usually of a greenish or bluish colour. 1938H. G. Byers et al. in Yearbk. Agric. (U.S.) iv. 975 The bluish or greenish waterlogged horizons are sometimes called glei or gley, and the process by which they are formed is sometimes called gleization. 1949Jrnl. Soil Sci. I. 205 It is not clear when it was first realized that gleying is caused by a microbial reduction of ferric compounds. Ibid., A laboratory study of the gleying process. 1949J. S. Joffe Pedology (ed. 2) xi. 430 Morphologically, the B horizon has also been affected by the gleiing process. 1956C. D. Pigott in D. L. Linton Sheffield 80 Where water-logging occurs..the soils are gleyed and in many places the ground flora is almost exclusively dominated by Allium ursinum. 1971Nature 1 Jan. 45/1 Marked peatiness of the soil and gleying are only found toward the upper limit of lower Montane forest.
