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.
A labile carbon input would displace some phosphorus into the soil solution, thus making it available again for assimilation into growing plants.
By enhancing our understanding: 1) of the nitrogen supply dynamics associated with the use of mixed green and farmyard manure applications, and 2) of the timeline of nitrogen uptake by garlic; we hope to fine-tune fertilization strategies so they meet the needs of garlic crops, while minimizing phosphorus accumulation and nitrogen leaching.
This project aims to develop a GHD-based fertilizer management system using split band applications for high-N-demand crops grown in rows, e.g., summer cabbage.
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 aims to assess the impact of cropping practices on baby lettuce yields and quality on muck soil.
This project was aimed at determining potassium doses (5 doses) to apply before planting on nitrogen-fertigated cucumber crops grown on plastic mulch.
The goal of this project was to measure the impact of irrigation management on nitrogen uptake and available soil nitrogen on several cultivars under commercial production conditions.
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.
Using a split-split-plot design, this study tested three variables: soil tillage, crop rotation in organic production, and fertilization with manure or compost.

This project was aimed at determining the nutrient needs of beets based on soil texture and phosphorus and potassium levels under Québec growing conditions.
