Field crops (grain corn and soybeans) are grown on over 800,000 ha in Québec. They are a big source of farm income but also account for most of the glyphosate-based herbicide (GBH) used in the province. Maintaining high field crop yields while drastically reducing use of GBH is strategically important if this sector is to remain prosperous and sustainable.
The aim of the project is to assess the impact of applying various rates of glyphosate in field crop systems on the soil and crop rhizosphere microbiome. This IRDA project covers one aspect of a broad interdisciplinary study led by Dr. Marc Lucotte at UQAM. The purpose of the NSERC-funded study is to provide an overall picture of the massive use of GBHs in a variety of conventional field crop systems and systems with a permanent plant cover requiring very few GBH applications. The IRDA study will consist of taking microbiome samples in the field in two of Québec’s climatic zones and in research plots run by SCV Agrologie.
From 2017 to 2021
IRDA’s involvement in this project will lead to a reduction in the use of glyphosate herbicides.

Experimenting narrow-row crop weed control strategy on three crops: green beans, peas, and soybeans.

This project is to arouse interest in approaches to soil health and conservation and to promote their adoption by a greater number of Quebec field crop farmers.
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.
