ISRIC - World Soil Information Database



© European Communities, 1995-2007Since its beginning in 1966, ISRIC - World Soil Information has built up a collection of more than 20.000 articles, country reports, books and maps with emphasis on the developing countries. The subject emphasis is on soils, but related geographic information on climate, geology, geomorphology, vegetation, land use, and land suitability is also important. The map collection contains over 6000, mainly small-scale (1:250.000 or smaller) maps. more...

Trace Elements in Soil Pore Water

the study assessed whether Rhizon™ samplers, centrifugation, high pressure squeezing and soil suspensions in simulated pore water can be viable approaches for obtaining representative samples of equilibrated soil pore water. Results for metal solubility and speciation were interpreted in terms of both soil morphological effects on trace metal dynamics and artefacts introduced at various stages during sample preparation and handling. Pore waters showed different ranges of concentration between the various methods. Different mechanisms and/or chemical reactions were involved during the different extractions.
