A continuous, real-time emissions monitoring study was initiated at a commercial dairy farm in Ontario, Canada, in 2024. The main objectives of this study are 1) to evaluate the impacts of emission reduction practices co-developed by researchers and farmers for nitrous oxide (N₂O) and carbon dioxide (CO₂) emissions mitigation while promoting crop yield, 2) to understand how scientific results can be better communicated to farmers, 2) to make the ‘invisible’ visible leading to improved understanding by farmers of emissions and the scientific process in determining emission reductions.

The use of co-developed practices in corn silage (dual nitrification and urease inhibitors and a 15% reduction in UAN application rate) resulted in 27.8 % lower cumulative N₂O emissions in the cropping season of 2024, a 58 % increase in nitrogen use efficiency, and 11 % greater crop yield compared to the conventional field. Cumulative emissions from perennial fields (alfalfa) were approximately 76 % lower than those of annual crop (corn silage).
