Dashboard for visualization of changes and cumulative values (at national level) for:
  • N mineral fertilization
  • NO3 leaching
  • N2O
  • SOC (Soil Organic Carbon)
Map data come as output of DatyCent model and have been aggregated at country level. The scenario involves the decrease and increase of 20% of mineral N in surplus and in potential mining areas, respectively.
 
The dashboard consists of:
  • Four web maps showing raster values of rate change. Labels show cumulative values at national level.
  • A detail window showing a summary of values for the selected country(ies)
Reference year:
Unit of measures for rate change and cumulative values respectively:
  • N mineral fertilization: [kg/ha/y] and [kt/y]
  • NO3 leaching: [kgNO3-N/ha/y] and [kt/y]
  • N2O: [kgN2O-N/ha/y] and [kt/y]
  • SOC (Soil Organic Carbon): [t/ha] in the topsoil 0-30 cm layer at equilibrium and [Mt/y]
Spatial coverage of aggregated data: EU27
Map image layer reference system: EPSG 3857 WebMercator.
