1923Soil Sci. XVI. 97 It is the presence of the acid layer in a definite position in the profile and the strongly marked gray or podsolized horizon which chiefly distinguishes the typical northern from the typical southern profile. 1927C. F. Marbut tr. Glinka's Great Soil Groups of World 100 Traces of the Podsolizing processes are shown in shallow depressions... The Podsolizing and leaching has reached a more advanced stage of the development. 1932Technical Communications Imperial Bureau Soil Sci. No. 24. 11 Under conditions of poor drainage..resilication may give rise to a kaolinite red earth which..may be podsolised into a quartzose, bleached surface soil. 1938Geogr. Jrnl. XCI. 163 The soils of the lower Trent Vale are podsolized sands. 1957Soil Sci. LXXXIII. 215 The parent materials of Swartswood sand loam podzolize with comparative ease. 1976Sci. Amer. Apr. 56/3 The dunes are partly podzolized, and they sustain pines, dwarfed redwoods and shrubs. 1976Nature 15 Apr. 602/2 It would seem to result from percolating solutions removing surface coverings of ferric oxides from quartz sand grains and depositing them again within a short distance, that is, in a typical podzolising process.
Hence ˌpodzoliˈzation, the leaching of bases out of the upper parts of a soil and their deposition lower down; the formation of a podzolic soil.
1923Soil Sci. XVI. 103 It is evident..that podsolization may take place in acid or alkaline [s]oils. 1934Discovery July 200/2 The leaching and subsequent deposition of iron (and aluminium) oxides is a characteristic of all podsols, and is..generally referred to as ‘podsolization’. 1952P. W. Richards Tropical Rain Forest ix. 209 The removal of sesquioxides of iron and aluminium with the accumulation of silica is called podzolization. 1970E. M. Bridges World Soils iii. 21/1 The process of podzolization is prevalent in the soils of the cool humid parts of the world and produces soils of the podzolic group and the podzols in particular. |
