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.
Test whether or not commercial strains coated on Nantes carrot seeds can compete with native strains in the soil to colonize the host plant and, once symbiosis takes place, whether they succeed in doing a better job than the native strains during the transition to organic farming.
This project proposes an intervention in a typical potato cropping system to enhance the crop uptake of water and nitrogen.

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 tests cost-effective organic fertilization strategies for summer strawberries on plastic.
The objective of this project is to develop a prediction model for soil nitrogen supplies based on biological soil health indicators.
The aim of this project is to show that efforts made to better distribute phosphorus on the land are effective and that the indicators used to determine phosphorus saturation thresholds are correlated with soil phosphorus balance and dynamics.

There is a great need to test green manure as a main source of nitrogen for potatoes as they help to maintain soil quality and control weeds.
Meeting nitrogen requirements mainly through the use of a highly stable form of fertilizer can minimize nitrogen losses, provide nitrogen amounts closer to the plant’s actual needs.
This project will determine the nitrogen efficiency coefficient (EC) of pelleted laying hen manure, a source that is interesting an increasing number of growers, both organic and conventional, because of its efficiency.
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.
