Abstract:

A micrometeorological inverse dispersion technique was used to measure ammonia (NH₃) at three dairy farms in Ontario, Canada. The dairy operations represented a range of farm management systems, including solid-liquid separation, and anaerobic digestion. Campaigns were conducted seasonally and were designed to partition sources (e.g. barns, manure storages) within the operation as well as measure emissions from the whole operation. Preliminary results including diurnal cycling, seasonal averages, source partitioning, and emissions in relation to nitrogen content will be presented.
