Ammonia (NH3) emissions from farm operations have been identified by the National Agri-Environmental Health Analysis and Reporting Program (NAHARP) as one of the quantitative indicators of agricultural environmental performance in Canada. Based on current estimates, about 6% of all Canadian emissions can be attributed to land application of poultry manure. The Fraser Valley of B.C. generates large quantities (approximately 280,000 tonnes) of poultry manure each year. While land application of poultry litter can provide essential plant nutrients for crop production, improper manure management can lead to ammonia volatilization from the litter, and it can be detrimental to the environment.
