Municipal biosolids are a nitrogen (N)-rich agricultural fertilizer which may emit nitrous oxide (NO) after rainfall events. Due to sparse empirical data, there is a lack of biosolids-specific NO emission factors to determine how land-applied biosolids contribute to the national greenhouse gas inventory. This study estimated NO emissions from biosolids-amended land in Canada using Tier 1, Tier 2 (Canadian), and Tier 3 (Denitrification and Decomposition model [DNDC]) methodologies recommended by the Intergovernmental Panel on Climate Change (IPCC).

Nonetheless, independent studies have been carried out across Canada.
