Environmental benefits of shelterbelts on agricultural farmlands
Shelterbelts accumulate atmospheric C in plant biomass
Increase soil carbon
Reduce N2O emissions due to deep roots
Increase soil CH4 oxidation
Knowledge gap – Changes on total farm GHG emissions due to the integration of shelterbelts is not well understood
Objective
To assess the impact of five levels of white spruce (Picea
glauca) shelterbelt establishment on the global warming
potential of a model farm after 60 years of cultivation
