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.
Demonstration project to showcase the ability of undersown clover cover crops to reduce nitrogen fertilizer requirements in crops.
Researcher: Marc-Olivier Gasser
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.
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.
Using a split-split-plot design, this study tested three variables: soil tillage, crop rotation in organic production, and fertilization with manure or compost.
Researcher: Caroline Côté
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.
The aim of this project was to gather data on the nutritional requirements of barley to better equip producers, extension agents, and other industry stakeholders.
The aim of this project was to gather data on the nutritional requirements of oats to better equip producers, extension agents, and other industry stakeholders.
To provide information on the fertilizing value and environmental impact of spreading pig manure at different times, the project compared the effect of mineral fertilizer in early fall, late fall, and in the spring.
This project was aimed at identifying and incorporating biological indicators into decision support tools used to assist producers and agroenvironmental regulatory bodies seeking to preserve soil productivity and use sustainable production systems.
Researcher: Richard Hogue
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.
The project was designed to assess the profitability of various types of cover crops and planting methods at the farm level.
The purpose of the project was to assess the benefits of controlled farm drainage under current and future climatic conditions to meet the water needs of field crops and rural communities while reducing nitrogen and phosphorus flows into watercourses.
