The first campaign provided site-specific emission factors for dairy cattle urine (540 kg N ha-1), dairy cattle dung (1132 kg N ha-1) and urea fertiliser (50 kg N ha 1) on a ryegrass-clover sward of 1.53%, 0.24% and 0.17%, respectively. 

THESE AMOUNTS OF DUNG DEPOSITED SEEM VERY HIGH TO ME. THE EF FOR N UREA LOOKED VERY LOW PRESUME BECAUSE MOST WENT OF AS AMMONIUM???
