Modelling and measurement of ammonia emissions from ammonia mitigation pilot farms - AM0102

The main objectives of this project are to verify that similar reductions in ammonia emission can be achieved on commercial farms using abatement techniques, such as slurry injection or covering stores, to those measured under experimental conditions. Measurements conducted on two of the farms in which such abatement techniques are being piloted (WA0710) will also provide farm-specific data for whole-farm ammonia emission models being developed (WA0705) and improve the robustness of emission factor estimates for inventory purposes. The ammonia emission module of the MEASURES model (WA0801) will be improved and MEASURES used to assess the long term environmental and financial burdens of the study farms.

There are international pressures to reduce ammonia emissions from agriculture. Information regarding the effectiveness of ammonia emission abatement techniques on existing commercial farms, together with the development of predictive whole-farm models will aid MAFF in developing appropriate strategies to meet requirements for ammonia abatement, within an integrated framework including other pollution issues.
The overall objectives of the project are to assess the effectiveness of ammonia mitigation strategies being employed on commercial farms and to provide data for ammonia loss models being developed under separate projects. Specific objectives are:
1. Measure ammonia emission factors for manure spreading and storage on 2 commercial farms where abatement techniques are being employed and compare these with results of previous experimental trials and published emission factors
2. Measure ammonia emission factors for animal housing and hard standings on the same 2 commercial farms
3. Provide farm-specific data for the empirical whole farm ammonia emissions model, MAST (developed under WA0705)
4. Provide farm-specific data for the process-based whole farm ammonia emissions model being developed under WA0705
5. Further develop MAST so that it is compatible as an ammonia emissions input module to MEASURES
6. Assess the long-term financial and environmental burdens of the farms using MEASURES
