Research Projects

This project looks to develop decision-support tools informed by observations of “bellwether” plots and use these tools to disseminate relevant information to irrigators.

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.

This project proposes an intervention in a typical potato cropping system to enhance the crop uptake of water and nitrogen.

The goal of the project is to improve biological methods for controlling the cabbage seedpod weevil in canola crops. In this project, initiated by Agriculture and Agri-Food Canada and conducted in Québec by UQAM, IRDA is performing an economic analysis of the practices under study.

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.

This project aims to improve our understanding of the evolution and spatial variability of soil health indicators as barometers of climate change.

Testing the efficacy of four biofungicides against Sclerotinia in soybeans.

Demonstration project to showcase the ability of undersown clover cover crops to reduce nitrogen fertilizer requirements in crops.

The objective of this project is to develop a prediction model for soil nitrogen supplies based on biological soil health indicators.

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.

Economic analysis of a three-year project aimed at testing methods of reducing and correcting surface soil compaction.

Economic analysis of using flower strips around soybean fields to serve as a reservoir for aphid species attacked by Pandora neoaphidis.

This two-year project, conducted at the Organic Agriculture Innovation Platform, compared the effect of three seeding dates and three seeding rates on chia yields.

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.

IRDA—in its capacity as the authorized representative tasked with revising the MAPAQ fertilization reference charts—will plan, coordinate, and monitor all activities involved in updating these charts.
