The Rivière de la Roche sub-watershed has one of the highest phosphorus and sediment export rates of the entire Missisquoi Bay watershed—a particularly challenging situation for the local agricultural sector. This project’s goal is to locate the main sources of phosphorus discharge into the watershed and identify agri-environmental action plans that could reduce the phosphorus load entering Missisquoi Bay by 40%. We will conduct a cost-benefit analysis of the proposed plans in order to facilitate the acceptance and adoption of alternative management practices by the surrounding farming community.

To provide information on the fertilizing value and environmental impact of spreading pig manure at different times, the project compared the effect of mineral fertilizer in early fall, late fall, and in the spring.
Canola and wheat (wheat-corn-canola rotation) were planted in 2016 and 2017, respectively, on 12 experimental plots with tillage practices on the main plots (minimum tillage and chisel plow) and fertilization methods (mineral fertilizers, 25 m3/ha of pig manure and 50 m3/ha of pig manure) in the subplots.
This project proposes an intervention in a typical potato cropping system to enhance the crop uptake of water and nitrogen.
