Pathway to 2040
Pathway to 2040 is the PEI Federation of Agriculture’s plan to lead the sector on climate action while ensuring a robust and successful industry that continues to drive the provincial economy. Pathway to 2040 outlines the BMPs Island farmers can put to work and assesses the impact they will have on the industry’s emissions.
Projected Annual GHG Emissions for PEI Agriculture with BMP Implementation
Best Management Practices
The opportunities available for reducing emissions are different for growing crops and raising livestock.
Potential GHG Reductions FROM Cropping BMPs
Reduced Nitrogen Use
Optimizing nutrient use efficiency, especially for nitrogen fertilizers is shown to reduce N2O emissions. The use of slow-release fertilizers combined with rate reductions and biological nitrogen supply testing has resulted in N2O reductions.
Increased Cover Cropping
Cover cropping extends root growth longer into the cool season allowing plants to sequester more GHGs into the soil.
Decreasing soil disturbance and slowing down decomposition of soil carbon can add up to 0.4 mt of soil Carbon per hectare per year.
Increased Rotation Length
Improved rotations can add up to 1 tonne of soil carbon for evert hectare each year.
Potential GHG Reductions From Livestock BMPs
Improved grazing practices can lead to emission reductions through intensive management (stocking rates and density, paddock design) and productivity maximization (cultivar selection, nutrient management).
Improved diet, vaccines, and feed quality can lead to methane reductions from ruminant animals such as cattle and sheep. Adding asparagopsis to feed has been found to reduce methane emissions in lactating dairy cattle by 50%.
Adding sulfur to liquid manure can significantly reduce emissions. liquid manure or solid manure incorporated properly can lead directly to reduction in required nitrogen fertilizer use.
