solod Soil Science.|ˈsɒlət|
Also soloth. Pl. (sometimes const. as sing.) solodi, soloti; also solods.
[a. Russ. sólod′, f. sol′ salt.]
A type of soil derived from a solonetz by leaching of saline or alkaline constituents, having a pale, leached subsurface horizon, and occurring characteristically under grass or shrub vegetation in semi-arid and desert regions.
1925S. A. Waksman tr. K. K. Gedroits's Soil Absorbing Complex & Absorbed Soil Cations (U.S. Dept. Agric.) 13 The process of forming a new type of soil from an alkali soil as a mother soil leads to secondary soils (‘soloti’), which are distinguished from primary podsol soils both in origin and in the properties of the formation. 1933Soil Sci. XXXVI. 181 The solodi profiles of the semiarid short grass plains zone. Ibid. 184 (caption) A well-developed solodi. 1934Ibid. XXXVIII. 484 After the complete formation of Soloth with the removal of the mobile colloids, the continued growth of the native grasses again changes the soil to that normal for the region. 1953Proc. Soil Sci. Soc. Amer. XVII. 287 Solod soils ordinarily occur in the lowest local position in the landscape, usually a deep depression, while Solonetz and solodized Solonetz soils develop on level areas or in slight depressions. 1963D. W. & E. E. Humphries tr. Termier's Erosion & Sedimentation xv. 324 The soloti are the degraded alkaline soils derived from solonetz soils by solotization, a process analogous to podsolization. Ibid. 325 Solotis are known in the U.S.S.R. and in the western United States. 1974E. A. Fitzpatrick Introd. Soil Sci. vii. 119 Solods can be regarded as leached solonetzes in which the upper horizons are strongly bleached becoming pale grey or white.
Hence soˈlodic a., being, resembling, or characteristic of a solod; ˈsolodize v. intr., to change into a solod; solodiˈzation (also solot-), the formation of a solod by the leaching of salts from a solonetz; ˈsolodized (solot-) ppl. a., altered by this process.
1925S. A. Waksman tr. K. K. Gedroits's Soil Absorbing Complex & Absorbed Soil Cations (U.S. Dept. Agric.) 14 Just as the carbonates of calcium and magnesium protect the soil of forest zone from podsolization, these salts protect alkaline soils from ‘solotization’. Ibid. 15 The question of the presence of absorbed hydrogen in solotized soils is still not clear. 1932E. J. Russell Soil Conditions & Plant Growth (ed. 6) iv. 269 In this process of solodisation, the percolating water continues to remove sodium and other products of decomposition from the soil complex, replacing the exchangeable sodium by hydrogen, and depositing the products of decomposition lower down. 1934Soil Sci. XXXVIII. 484 As soon as solonetz forms it immediately begins to solotize with the development of a profile approaching the soloth. 1964Jrnl. Soil Sci. XV. 176 The absence of solodized-solonetz from the deep sands is related to the coarser texture of the material of which they are composed. 1968H. C. T. Stace et al. Handbk. Austral. Soils vi. 153 In the solodized solonetz, solodic soils and red-brown earths the topsoil is acid.., but all..contain secondary carbonate in the deeper horizons. 1978Faniran & Areola Essent. Soil Study viii. 183 Salinization, solonization, and solodization..resulting in the formation of solonchaks, solonetz, and solodic soils respectively. |
