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.

Green manure
2014-2017 • Field crops

Agronomic and environmental impacts of various types of organic fertilizers and green manures in field crop production

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.

Marigold flowers
2015-2018 • Market gardening

Potential of a flowering plant mix to encourage natural enemies of caterpillar pests on crucifers (cabbage family)

This three-year project looked at optimal ways to use a mix of flowering plants against caterpillar pests of crucifers.

Potatoes
2014-2017 • Market gardening

Assessing the potential of using granulated potato residues to produce animal feed, fertilizers, and energy

Managing potato residues is therefore a big challenge, which will only increase with the enforcement of the Québec Residual Materials Waste Management Policy.

Green manure
2014-2017 • Market gardeningField crops

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.

Strawberries
2013-2018 • Fruit production

NPK trials for strawberries on mineral soils in Québec

The data generated by this project was used to develop a new NPK fertilization chart that reflects technical, agronomic, and environmental issues.

Beetroots
2013-2018 • Market gardening

NPK fertilizer trials for beets on mineral soils in Québec

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

Barley
2013-2017 • Field crops

NPK fertilizer trials on barley on mineral soils in Québec

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.

Blueberries
2016 • Fruit production

Detecting spores of Pucciniastrum geopertianum, the fungus that causes blueberry witches’ broom rust

The aim of the project was to determine whether the witches’ broom symptom on blueberries is really caused by the rust Pucciniastrum geopertianum, which attacks balsam.

Potatoes
2016-2017 • Market gardening

Adapting quantitative detection methods for determining silver scurf injury thresholds both in the soil and on seed potatoes to model potential economic losses

The fungal pathogen Helminthosporium solani causes silver scurf, a disease that is hard to detect, both in the soil and on harvested potatoes.

Laying hens
2016-2018 • Livestock production

Revising the nutrient balance sheet for estimating phosphorus loading in laying hen production

This project was set up to test the nutrient balance sheet method as a tool for estimating phosphorus output from pullets and laying hens.

Researcher: Marc-Olivier Gasser

2014-2017 • Field crops

Determining the ideal time to spread pig manure to improve crop yield and protect soil, water, and air quality

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.

Wild blueberries
2016-2017 • Fruit production

Evaluation of technical efficiency and financial performance of wild blueberry production in Québec

This economic analysis measured the technical efficiency of Québec wild blueberry farms.

Exclusion nets
2014-2018 • Fruit production

Exclusion nets for organic apple production in Eastern Canada

The aim of this project was to test the general hypothesis that exclusion nets, when properly used, can prevent attacks by most apple pests and reduce disease incidence with no major adverse effects on fruit quality.
