[EN] Synthetic nitrogen (N) fertilizer and field application of livestock manure are the major sources
of ammonia (NH3) volatilization. This N loss may decrease crop productivity and subsequent
deposition promotes environmental problems associated with soil acidification and
eutrophication. Mitigation measures may have associated side effects such as decreased crop
productivity (e.g. if N fertilizer application is reduced), or the release of other reactive N
compounds (e.g. N2O emissions if manure is incorporated). Here, we present a novel
methodology to provide an integrated assessment of the best strategies to abate NH3 from N
applications to crops. Using scenario analyses, we assessed the potential of 11 mitigation
measures to reduce NH3 volatilization while accounting for their side effects on crop
productivity, N use efficiency (NUE) and N surplus (used as an indicator of potential N losses by
denitrification/nitrification and NO3
− leaching/run-off). Spain, including its 48 provinces, was
selected as a case study as it is the third major producer of agricultural goods in Europe, and also
the European country with the highest increase in NH3 emissions from 1990 to 2011. Mitigation
scenarios comprised of individual measures and combinations of strategies were evaluated at a
country- and regional level. Compared to the reference situation of standard practices for the year
2008, implementation of the most effective region-specific mitigation strategy led to 63% NH3
mitigation at the country level. Implementation of a single strategy for all regions reduced NH3
by 57% at the highest. Strategies that involved combining mitigation measures produced the
largest NH3 abatement in all cases, with an 80% reduction in some regions. Among the strategies
analyzed, only suppression of urea application combined with manure incorporation and
incorporation of N synthetic fertilizers other than urea showed a fully beneficial situation: yieldscaled
NH3 emissions were reduced by 82%, N surplus was reduced by 9%, NUE was increased
by 19% and yield was around 98% that of the reference situation. This study shows that the
adoption of viable measures may provide an opportunity for countries like Spain to meet the
international agreements on NH3 mitigation, while maintaining crop yields and increasing NUE
