Fig. 2: Temperature sensitivity of NH3 volatilization.
From: Global warming increases ammonia emissions and reduces the efficacy of mitigation actions

Temperature sensitivity is expressed as percentage change in the fraction of available N volatilized as NH3 per °C compared with baseline emissions for 2010 (excluding mitigation measures). a All crop and livestock sources, b synthetic fertilizer use, c livestock housing, d manure storage (inc. manure processing), e manure application to land and f grazing.
