Calculates total nitrogen inputs to soils in Spain at the provincial level. This includes contributions from:
Atmospheric deposition (
deposition)Biological nitrogen fixation (
fixation)Synthetic fertilizers (
synthetic)Manure (excreta, solid, liquid) (
manure)Urban sources (
urban)
Special land use categories and items are aggregated:
Semi-natural agroecosystems (e.g., Dehesa, Pasture_Shrubland)
Firewood biomass (e.g., Conifers, Holm oak)
Value
A tibble containing:
year: Yearprovince_name: Spanish provinceitem: Crop, land use, or biomass itemirrig_cat: Irrigation form (irrigated or rainfed)box: Land use or ecosystem box for aggregationdeposition: N input from atmospheric deposition (Mg)fixation: N input from biological N fixation (Mg)synthetic: N input from synthetic fertilizers (Mg)manure: N input from livestock manure (Mg)urban: N input from urban sources (Mg)
