I can answer the question in general terms.

On page 8 of my presentation, there's a chart. Overall, animals, such as cows, are responsible for about 40% of Canada's greenhouse gases when CO₂ or the equivalent is used. Manure is responsible for about 10% to 15% of greenhouse gases. The N₂O from soil is also responsible for about 40% of the gases. Managing N₂O in the soil is therefore a major challenge for conservation.
