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

2018-2020 • Field crops

A study on synchronizing the supply of n from green manure in order to reduce or replace the use of swine slurry as a fertilizer for post-emergent corn, in the context of the transition to organic farming

This project’s main goal is to demonstrate how to satisfy most of the requirements of a strongly N-dependent crop by improving N-supply synchronization, while protecting the farmers’ prior year revenue-generating window.
