Tiivistelmä: Agricultural gaseous nitrogen emissions are mostly related to manure management, grazing and fertilisation. These emissions include ammonia (NH3), nitrous oxide (N2O), nitric oxide (NO) and di-nitrogen (N2). Most of the non-methane volatile organic compounds (NMVOC) emissions originate from livestock farming, but also from cultivated crops. All these emissions are inventoried and reported for the UN Convention on Long-range Transboundary Air Pollution (CLRTAP), EU National Emission Ceilings Directive (2001/81/EC) and the UN Framework on Climate Change (UNFCC). In Finland, a specific national model for gaseous nitrogen emissions from agriculture has been used for the inventory since 1998. The revised calculation model documented here is tied to the Finnish Normative Manure System, which provides data on manure quality and quantity for various livestock categories. The emission calculation follows the flow of total ammoniacal nitrogen (TAN) and total nitrogen (N) through the manure management systems, starting from excretion and ending at manure spreading. The main manure management phases considered in the calculation are livestock housing, manure storing and manure field application. The calculation also embeds estimations on emissions from grazing and outdoor yards, as well as emissions from the use of mineral fertilisers. The nitrogen calculation model provides data for the calculation of agricultural NMVOC emissions. All calculations are constructed in compliance with the Tier 2 method of the EMEP/EEA emission inventory guidebook (2016).
