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.
Impact of irrigation system management and cultivar on nitrogen use by potatoes under commercial production conditions
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.

Integrated approach to nitrogen fertilization for profitable organic potato production and a balanced phosphorus budget
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.

Effect of legumes, manure, and compost on soil nitrogen dynamics and microbial diversity under organic production
Using a split-split-plot design, this study tested three variables: soil tillage, crop rotation in organic production, and fertilization with manure or compost.
