Potential nitrate discharges in kg N/(ha*a) according to § 8 AVV GEA of the reference parcels in NRW, as of 01/2022

The current agricultural N balance sheet surplus in kg N/(ha*a) is presented as the 4-year average of the period 2016-2019 per reference parcel. Data are based on the agricultural N balance sheet surplus per municipality for the period 2016-2019 (arithmetic mean) as determined by Appendix 4 AVV GEA by the DLWK. The conversion of the N-balance sheet surplus per municipality to the agricultural areas in the model grid (100 x 100 m) of the hydrological substance entry model GROWA+ NRW 2021 is carried out according to the interface RAUMIS/mGROWA-DENUZ-WEKU (see Annex 4) by LANUV NRW. The current N balances determined in this way (2016-2019) per reference parcel are issued per field block according to field block statistics NRW 2021. The data set contains the field blocks according to field block statistics NRW 2021 as polygons (Feature in geodatabase “GLDN Potential Nitratetraege-to-Par-8-AVV-GeA_EPSG25832_Geodatabase.gdb” and shape “GLDN-Potenzielle_Nitratetraege-to-Par-8-AVV-GeA_EPSG25832”)
