By improving the efficiency of fertiliser use, emissions of N<sub>2</sub>O, NO and NH3 can be decreased ([[Van Vuuren et al., 2011b]]). By increasing the amount of feed crops in the cattle rations, CH<sub>4</sub> emissions can be reduced. Production of crop types has a significant influence on emission levels of N<sub>2</sub>O, NOx and NH3 from spreading manure and fertilisers. | ||

Some fertilisers cause higher emissions of N<sub>2</sub>O and NH3 than others. Incorporating manure into soil lowers emissions compared to broadcasting. | ||
The impacts of more ambitious control policies ({{abbrTemplate|CLE}} versus {{abbrTemplate|EKC}}) on SO<sub>2</sub> and NOx, emissions, and the influence of climate policy are presented in the figure below. Where climate policy is particularly effective in reducing SO<sub>2</sub> emissions, air pollution control policies are effective in reducing NOx emissions. | The impacts of more ambitious control policies ({{abbrTemplate|CLE}} versus {{abbrTemplate|EKC}}) on SO<sub>2</sub> and NOx, emissions, and the influence of climate policy are presented in the figure below.
