Main topics at the international WRB field excursion, Norway 2010
- Soils with a high content of clay and silt with low water permeability cover a large area of the most important arable land in Norway. These soils have stagnic and/or gleyic colour patterns, and have been artificially drained for cultivation. Discussions at four sites.
- Some soils with a high content of clay and silt also have an abrupt textural change within 100 cm of the soil surface, shore deposits covering marine deposits. Are these Planosols? Discussions at two sites.
- In order to be able to use heavy machinery in steep and hilly areas, large areas of agricultural land were levelled during the 1960's and the 1970's. These were mainly marine deposits. Where in WRB do these fit? Discussions at two sites: one of them showing an unlevelled area, the other one a levelled area with the same original soil.
- The Norwegian Forest and Landscape Institute is using an adjusted version of the WRB in the ongoing soil survey. More than 50% of the total arable land in Norway has now been mapped, and the data is available for free at the website of the institute (pages in Norwegian only). To the right at this page there is a link to the maps. The survey has been done at a detailed level. During the last years a new method has been tried, at a smaller scale, 1: 50000. Both methods will be shown, two sites.
