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

Agronomic and environmental impacts of various types of organic fertilizers and green manures in field crop production
This project evaluated the impact of various corn, soya, and wheat fertilization methods on marketable yields, harvest quality, nitrate losses, and movement of microorganisms potentially pathogenic for humans.
Researcher: Caroline Côté
NPK fertilizer trials on barley on mineral soils in Québec
The aim of this project was to gather data on the nutritional requirements of barley to better equip producers, extension agents, and other industry stakeholders.

Effectiveness of an annual vs. end-of-season legume green manure crop in increasing soil resilience and providing sufficient nitrogen
The project compared the nitrogen uptake effects of green manure crops grown for a full season, in association with a main crop, or after it is harvested.
Researchers: Aubert Michaud, retraité Marc-Olivier Gasser Maryse Leblanc
Developing a nitrogen fertilization program based on green manure supplemented by a manure-based starter fertilizer in organic grain production
In a wheat/grain corn/soya rotation, green manure can be used to obtain profitable organic grain corn yields while limiting phosphorus pollution.
Researcher: Christine Landry
Impacts of green manure on soil structure in the Estrie region
This project was carried out by Club agroenvironnemental de l’Estrie and IRDA was in charge of conducting the economic analysis.
