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

Subsoiling and temporary drainage in soils with low permeability
The project evaluated and compared the effectiveness of two types of subsoil plows (mounted on a bulldozer or a tractor) operated parallel and perpendicular to the tile drains to improve soil drainage conditions and productivity compared to control plots.

Using controlled drainage to optimize water and nutrient uptake by crops
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.
