World Soil Museum

The World Soil Museum (WSM) displays physical examples of soil profiles (monoliths) representing major soil types of the world, from the volcanic ash soils from Indonesia to the red, strongly weathered soils from the Amazon region. The museum is managed by the International Soil Reference and Information Centre (ISRIC), an independent, science-based foundation. Physically, the museum is located on the campus of Wageningen University and Research Centre in Wageningen, the Netherlands. The WSM (originally known as International Soil Museum) was created in 1996 at the request of UNESCO and the International Society of Soil Science, with a view to underpin the development of the FAO-UNESCO 'Soil Map of the World' FAO soil classification. The initial ISM building was located at the University of Utrecht. Some 80 soil monoliths are on display in the WSM, with a much larger collection (some 1000 from over 70 countries) stored and maintained in the repository. For each soil monolith, there is supplemental information about the site of sampling (e.g. landscape, land use, parent material and climate), a detailed profile description for each soil horizon or layer, and data on chemical compositions and physical features. The museum displays examples of the main (32) WRB Soil Reference Groups of the World.
