This is a HISTORIC data set, which is no longer updated.
The theme shows the nitrogen reduction potential from root zone to water body expressed in per cent. The reduction potential is used together with the mapping of catchment areas for vulnerable and highly vulnerable Natura 2000 areas* for the determination of nitrate classes in accordance with the Animal Authorisation Order**, see also the table below. The nitrate classes are used in the IT application system “husdyrattest.dk” for guidance in connection with the regulation of livestock farming under the Livestock Approval Act.
— Nitrate class III: Land for highly nitrogen-vulnerable areas with an N reduction potential of 0-50 %.
— Nitrate class II: Land for highly nitrogen-vulnerable areas with an N reduction potential of 51-75 %.
— Nitrate Class I: Catchment areas for vulnerable nitrogen areas with a N reduction potential of 0-50 %
— Outside the nitrate class: Land for nitrogen-vulnerable areas with a reduction potential of 51-100 %, and highly nitrogen-vulnerable areas with a N reduction potential of 76-100 % and other catchments to areas that are not nitrogen-vulnerable
