On-farm manure management is one of the most significant environmental challenges facing modern livestock agriculture. Containing and treating manure in an efficient manner is essential to minimize the hazards of both point and non-point source water pollution and also meet more stringent air quality standards. During the storage of manure, several undesirable gases including ammonia, methane and nitrous oxide can be released. The anaerobic nature of liquid manure systems also increases its potential for odour production. Several management strategies have therefore been suggested to mitigate gaseous emissions from storages. The objectives of this research program are to quantify emissions of multiple gases emanating from manure storages and develop strategies for their reduction while also examining specific tradeoff issues. Over the next five-years we will train 3 PhD, 3 MSc and a research technician through this novel research program. Utilizing a unique and state-of-the-art research facility we will quantify emissions from different management systems simultaneously which will allow for the development of farm-level recommendations for Canadian climatic conditions. This research will provide new knowledge linking greenhouse gas, ammonia and odour emissions from manure storage facilities and will have a significant impact on Canada's ability to accurately estimate emissions from the agriculture sector.
