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.

农家肥管理是现代畜牧业面临的最重大的环境挑战之一。以有效的方式控制和处理粪便对于尽量减少点源和非点源水污染的危害以及达到更严格的空气质量标准至关重要。在粪肥的储存过程中，可能会释放出几种不良气体，包括氨、甲烷和一氧化二氮。液体粪肥系统的厌氧性质也增加了其产生气味的可能性。因此，提出了若干管理战略，以减少储存的气体排放。该研究计划的目标是量化粪肥储存产生的多种气体的排放，并制定减少排放的战略，同时还研究具体的权衡问题。在接下来的五年里，我们将通过这个新的研究计划培养3名博士，3名硕士和一名研究技术人员。利用一个独特的和国家的最先进的研究设施，我们将量化排放量从不同的管理系统，同时这将允许为加拿大的气候条件的农场一级的建议发展。这项研究将提供新的知识，将温室气体、氨和粪肥储存设施的气味排放联系起来，并将对加拿大准确估计农业部门排放量的能力产生重大影响。
