1935 Trans. Third Internat. Congr. Soil Sci. III. 239 Volcanic phenomena only bring up a substratum on which pedogenesis is submitted to the same influences—mineral composition, climate, vegetation, etc.—as on any other.
1963 D. W. Humphries & E. E. Humphries tr. H. Termier & G. Termier Erosion & Sedimentation vi. 135 During pedogenesis (soil formation), the nature of the alteration of the titanium minerals depends more upon chemical diagenetic environmental conditions than on the nature of the parent rock.
1972 J. G. Cruickshank Soil Geogr. ii. 42 As part of the role of climate in pedogenesis, its moisture and temperature components also affect the rate of decay and incorporation into the soil of surface organic litter.
1999 Austral. Jrnl. Soil Res. (Nexis) 37 509 The role of vegetation in pedogenesis is well recognised.
