Soil - Risk of erosion
The Norwegian Soil survey is a systematic survey of soils on agricultural areas in mainland Norway. Data is collected by fieldwork which includes mapping the distribution of soil types by interpreting aerial photographs and verification and identification of soil types in the field using a soil auger. The boundaries between areas with different soil types are digitized in a GIS on site. Soil types are defined on the basis of major soil properties. The World Reference Base of Soil Resources (WRB) is linked as our national classification system, and is used as basis for our soil mapping units. A soil feature in the soil database is a continuous area with the same attributes assigned according to the classification criteria of soil types with a geometric representation as a polygon. Soil maps describes agricultural areal according to a national standardized classification systems of soil and other local attributes such as slope. Around 55 % of the country’s agricultural land has been mapped so far.
