Abstract
A model (MAST) to calculate the mass flow of NH3 through a model dairy farm has been developed. Updated emission factors for UK agriculture were used to examine different abatement strategies available for a typical dairy farm. A range of annual NH3 emissions was calculated for both slurry and FYM based dairy systems. Emission for the slurry based system ranged between 27 kg NH3-N ha−1 yr−1, achieved using a combination of abatement strategies, and 107 kg NH3-N ha−1 yr−1, calculated for a ‘worst case’scenario. For FYM, this range was between 33 and 86 kg NH3-Nha−1 yr−1. The greatest reductions were achieved by manipulating options linked to fertiliser usage and manure application.
