1 MITERRA-EUROPE Assessment of nitrogen flows in agriculture of EU-27 Oene Oenema, Jan Peter Lesschen & Gerard Velthof Wageningen University & Research Centre & 9 partners from 6 Member States

2 Outline Description of MITERRA-Europe Results N emissions NO 3 concentrations Conclusions

3 MITERRA-EUROPE A tool for integrated assessment of N (C and P) emissions from agriculture in EU-27 at Member State and regional levels Developed for the European Commission Based on information from CAPRI and RAINS/GAINS Simple/rapid model; uniform approach for EU-27 Scenario analysis

4 Understanding the cause-effect-benefit relationships

5 Output of MITERRA-EUROPE Nitrogen (P and C) balances Ammonia, nitrous oxide, denitrification and methane emissions from animal housing, storage and soils Nitrate leaching to groundwater and surface water Effects of measures (policies) to mitigate ammonia and nitrate emissions NEC, IPPC, Nitrate Directive, Water Framework Directive scenarios Soil organic matter and C sequestration

6 Crop production: - Crop type - Cropped area - Management Groundwater & surface waters N inputs: N fertilizer BNF, N deposition Animal production: - Animal species - Animal number - Management N outputs: milk, meat, egg NH 4 + NO 3 - DON N part NH 3 N 2 O NO X N 2 Atmosphere N outputs: harvested crop NH 3 N 2 O NO X N 2 Atmosphere Model concept for N; what comes in, must come out manure feed

7 Scales Spatial: 27 Member States Nuts 2 level Nitrate Vulnerable Zones Country level Temporal year

8 Input data FAO, EurostatFertilizer (national), yields CAPRI (Eurostat)Crop types and areas Distribution of animals over NUTS II RAINSAnimal types, number and N excretion Manure management system JRCSoil and meteorological data NVZ maps Alterra N contents of crops Crop residues Grassland area and yields

9 Calculations VariabeleMethod Fertilizer and manure distribution on Nuts 2 level Distribution based on N demand, N input, crops N and P surplusesSoil surface balance (OECD approach) Emission of NH 3, N 2 O, NOx, CH 4 Emission factors (~from RAINS) Leaching and denitrification (N 2 ): Manure storage Runoff Large surface water Groundwater and small surface water Site specific leaching fractions

11 N leaching pathways Leaching from stored manure Surface run-off from fields Shallow leaching to surface waters Leaching to below rooting zone

12 Site-specific leaching and surface-runoff fractions Surface-runoff fractions Slope, land-use, precipitation surplus, depth to rock, Application rate manure and fertilizer Leaching fractions Precipitations surplus, temperature, soil texture, land- use, rooting depth, soil organic C content, Nitrogen surplus

14 Runoff of N, kg ha -1 yr -1 Shallow N leaching to surface waters, kg ha -1 yr -1 N leaching to groundwater, kg ha -1 yr -1

15 Nitrate concentration in shallow groundwater, mg NO 3 l -1

16 Ammonia emissions kg N ha -1

17 Fate of N surplus (total N balance)

18 50% 100% Baseline 2020, current trend 2020, NH 3 measures 2020, NO 3 measures 2020, NO 3 measures, NH 3 measures Results of policy scenarios NH 3 emission NO 3 leaching 2020, NO 3 measures, low N feed N 2 O emission

19 Conclusions MITERRA-EUROPE applies a uniform and integrated approach for agriculture in EU-27 N balances on regional level N leaching and gaseous N emissions NO 3 concentration in shallow groundwater Scenario analyses EU Agriculture
