Researcher, Ph.D.
Description
The aim of this project was to consolidate current scientific knowledge with a view to developing a spatially referenced tool to predict diffuse sediment, nitrogen, and phosphorus exports at the farm and watershed scale.
Objective(s)
- Calibrate and validate a hydrological forecasting model for surface runoff, erosion, and phosphorus and nitrogen export rates based on hydrometric monitoring of small agricultural watersheds in Québec
- Update and develop algorithms to predict phosphorus and nitrogen flows at the experimental plot level
- Program a geolocalized tool to predict sediment and nutrient loss at the farm and watershed levels
From 2015 to 2018

Impact of manure management and tillage practices on water quality and safety in canola and wheat
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.
