Research Projects
Each year, IRDA's R&D Team conducts more than one hundred research projects in sustainable agriculture. What's more, IRDA is working with Quebec's key agricultural stakeholders to find concrete solutions.
Crop response to fertilizers as an index of soil health
Fertilizer response and soil health.
Researchers: Marc-Olivier Gasser Catherine Bossé Christine Landry
EPERLAB Project: A collective effort to study and restore Rivière Boyer
Project to restore the rainbow smelt spawning grounds at the mouth of Rivière Boyer on the St. Lawrence River.

Cost-benefit analysis of proposed actions to reduce the phosphorus load entering Missisquoi Bay from the Rivière de la Roche watershed
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.

Determining the ideal time to spread pig manure to improve crop yield and protect soil, water, and air quality
To provide information on the fertilizing value and environmental impact of spreading pig manure at different times, the project compared the effect of mineral fertilizer in early fall, late fall, and in the spring.
A diagnostic tool for phosphorus and nitrogen exports (P+N Edit)
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.
Researcher: Aubert Michaud, retraité
Developing new techniques to control water table levels in sphagnum farming
The objective of this project was to develop effective techniques for controlling water table levels in sphagnum moss basins. Underground irrigation systems were installed at a number of experimental sites.
Researcher: Stéphane Godbout
