  1. Nicht Landwirtschaft Pflanzenbau ÜbrigeNutztiere Geflügel Rindvieh Schweine 95% der Ammoniakemissionenaus der Landwirtschaft 1990, 1995 based on expert assumptions 2002, 2007, 2010 based on survey on manure management on representative stratified sample of farms Emission calculation with N-flux model AGRAMMON Why survey? Consulted experts can not reliably and comparable estimate changes that lead to 14% shift in emissions over 20 years Information on different regions, altitude zones, farm types Survey on development of livestock and manure management also valuable for other activities Allows a detailed assessment of the abatement potential Recent activities on ammonia emissions:Emission inventory

  2. Emission inventory Representative survey • 36 stratified classes (3 altitude zones, 3 geogr. Regions, 4 farm types) • Analysed sample: 3 % of farms; at least 50 per class • 12 page questionnaire • 1950 farms used for analysis Central Eastern Western

  3. Nicht Landwirtschaft Pflanzenbau ÜbrigeNutztiere Geflügel Rindvieh Schweine 95% der Ammoniakemissionenaus der Landwirtschaft Detailed assessment of farm specific abatement potential through individual and combined measures possible via AGRAMMON Detailed assessment of applicability of different measures  model calculations for abatement potential “Business as usual” Realistically feasible Maximum technically possible (without cost considerations) Regionally differentiated Recent activities on ammonia emissions:Assessment of emission abatement potential 95% der Ammoniakemissionenaus der Landwirtschaft

  4. Abatement potential Abatement potential in different regions (2002)

  5. Nicht Landwirtschaft Pflanzenbau ÜbrigeNutztiere Geflügel Rindvieh Schweine 95% der Ammoniakemissionenaus der Landwirtschaft Background Recent studies indicate standard emissions factors for slurry spreading might be too high (Sintermann et al. 2011) New experiments Comparison of field scale and medium plot size experiments New series of measurements with different application techniques Different measurement systems (mainly impinger + Windtrax) International collaboration Recent activities on ammonia emissions:New measurements on application losses 95% der Ammoniakemissionenaus der Landwirtschaft

  6. Nicht Landwirtschaft Pflanzenbau ÜbrigeNutztiere Geflügel Rindvieh Schweine 95% der Ammoniakemissionenaus der Landwirtschaft Ceiling value 2010 (-14%) was just achieved Awareness of farmers on need of emission abatement has increased. Mainly thanks to new agricultural policy with nutrient balance restriction AGRAMMON is a valuable tool for scenario calculations on emissions at farm or regional level Reliable emission inventory; good agreement with atmospheric concentration monitoring network Detailed assessment of emission mitigation potential Thanks to regular survey on livestock and manure management we have a good understanding of the development of emissions and farm/manure management Good collaboration between Federal Office and research What did we achieve? 95% der Ammoniakemissionenaus der Landwirtschaft
