3204. Abstracts
... Diko LINUS JACOB, Roger LANGOHR, Soil Science Unit, Univ. ... A reconnaissance survey performed in 1990 by R.L. on the Easter Island had shown that the soils developed on the three main volcanoes, the Terevaca, Rano Kau and Poike are deeply weathered. ... This seems to indicate that a strong erosion phase has truncated the soils. ... The chemical, physical and mineralogical data of this profile show that unit IV corresponds to the Bt horizon of a deeply weathered soil. ... Back to the Abstracts list...

3213. ESSAY
The paper "Classification of Paleosols" by Mack et al., (1993, hereafter called "the authors") [see related abstract on p. 9], read from a soil scientist's scope, evokes considerable criticism, some of which follows below. The purpose of classifying soils. ... Modern soil classification systems, such as Soil Taxonomy and FAO (1974, 1988, 1990) are meant to provide a link between unaggregated soil properties and a soil's potential uses. ... The latter are by no means new terms in soil science. ...

3214. Klumpen?a Mesoscale Level of Classification for Soil Structure: Rationale
The morphological character of earth material in soil profiles is popularly known as soil structure. ... However, descriptions and useful interpretations of soil structure can be made at any scale or "level of organization" (Brewer, 1964) . ... After a long search for a name that would avoid confusion with other contexts, I chose the term klumpen for this class and treated it as one level of soil structure. ... Soil structure and fabric: their definition and description. ...

3215. An International Consensus on Calcareous Paleosol Classification
Calcareous paleosols are widely distributed throughout the arid and semi arid regions of the world. These paleosols have been described from virtually every continent of the world, yet there is no internationally agreed upon nomenclature for the description of the horizons present within them. ... This abstract proposes the adoption of a universally agreed-upon system of horizon designation and gross morphological description of calcareous paleosols. ... Soil Science, 101, 347-360. ...

3216. Root Traces and the Identification of Paleosols
Two conclusions drawn by the working group at the 1970 Paleopedology Symposium in Amsterdam were that paleosols should be studied by the same methods as those used for present-day soils, and that field recognition should be based on the identification of more than one distinct pedogenic feature (Yaalon, 1971). ... Because paleosols are typically used to interpret past climates and lengths of time of subaerial exposure, a definition based on soil genesis, rather than plant growth, is advocated. ...
