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.
Improving the efficiency of rainwater and irrigation use in the potato cropping system
This project proposes an intervention in a typical potato cropping system to enhance the crop uptake of water and nitrogen.
Researcher: Carl Boivin
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.
Researcher: Christine Landry
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.
Researcher: Christine Landry
Revising the MAPAQ fertilization reference charts
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.
Researcher: Christine Landry
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.
