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.
This project aims to assess the impact of cropping practices on baby lettuce yields and quality on muck soil.
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.
This project was aimed at determining potassium doses (5 doses) to apply before planting on nitrogen-fertigated cucumber crops grown on plastic mulch.
This project aims to examine whether improving soil health can help check strawberry decline.
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.

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.
The objective of this project was to determine whether the addition of two types of organic fertilizers or biostimulants would produce more vigorous plants less subject to decline.
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.
A cropping system based on adding organic matter through soil amendments and organic fertilizers can restore soil health and strawberry yields by limiting the occurrence of disease symptoms.
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.

Using a split-split-plot design, this study tested three variables: soil tillage, crop rotation in organic production, and fertilization with manure or compost.

The data generated by this project was used to develop a new NPK fertilization chart that reflects technical, agronomic, and environmental issues.
This project was aimed at determining the nutrient needs of beets based on soil texture and phosphorus and potassium levels under Québec growing conditions.
