Evaluation of Kubiëna’s contribution to micropedology. At the occasion of the seventieth anniversary of his book “Micropedology”

“…calcitic) of the plasma. Other similar patterns were proposed by Brewer and Pawluk (1975) and Eswaran and Ba os (1976), the latter taking into account the general grain size distribution of the material (see also discussion in Stoops and Eswaran, 1986). ñ It is interesting to note that Kubiëna relied for his interpretations not only on optical observations, but that he applied several simple staining and/or heating tests to the studied material, a technique mostly forgotten in recent research.…”

Micromorphological Investigations of Cultivated Gray Luvisols Under Different Management Practices

“…Soil monoliths wcrc air-dried in the laboratory, impregnated with epoxy resin and cut into 5 x 7-cm thin sections according to standard procedures (Brewer and Pawluk 1975 (Tables 2 and 3) is based on terminology outlined by Brewer (1919 (Fig. 2c) The remaining fabric types recognized were described as intergrades as well as ctmplex fabrics (Brewer and Pawluk 1975 For personal use only.…”
