This project looks to develop decision-support tools informed by observations of “bellwether” plots and use these tools to disseminate relevant information to irrigators. A weekly advisory on the current situation (HebdEau) will report on the rainfall received, soil moisture conditions, water stress risks, and forecasted conditions over the following three days. At the end of those three days, or when the forecast calls for an unforeseen event (e.g., rain), an update report will be issued (ExpressEau). In addition, technical bulletins will be released throughout the summer to explain relevant irrigation management concepts and principles to farmers. HebdEau and ExpressEau will be produced with information collected from “bellwether” plots and from meteorological stations throughout the region.
From 2018 to 2019
Optimal water management
This decision-support tool will promote a better water management by producers.

This project relies on the continuous measurement of field water table heights; water exports; as well as sediment, nitrogen, and phosphorus runoff into drains at four field-crop production sites.

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.
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.
