Research Projects

This two-year project, conducted at the Organic Agriculture Innovation Platform, compared the effect of three seeding dates and three seeding rates on chia yields.

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.

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.

The purpose of this project was to study the vegetative propagation and regeneration capacity of Canada thistle and sow thistle with a view to developing effective weed control strategies.

The aim of the project was to estimate the economic impact of herbicide resistance in weeds.

In a wheat/grain corn/soya rotation, green manure can be used to obtain profitable organic grain corn yields while limiting phosphorus pollution.

IRDA was in charge of conducting the economic analysis for this project carried out by Club agroenvironnemental de l’Estrie (CAE Estrie).

A literature review, a survey of organic grain producers, and an analysis of historical yield and climate data in order to document the effects of climate extremes on yields and soil nutrient availability.

This project was carried out by Club agroenvironnemental de l’Estrie and IRDA was in charge of conducting the economic analysis.

The aim of this project was to consolidate current scientific knowledge with a view to developing a spatially referenced tool to predict diffuse sediment, nitrogen, and phosphorus exports at the farm and watershed scale.

The objective of this project was to develop effective techniques for controlling water table levels in sphagnum moss basins. Underground irrigation systems were installed at a number of experimental sites.

The project evaluated and compared the effectiveness of two types of subsoil plows (mounted on a bulldozer or a tractor) operated parallel and perpendicular to the tile drains to improve soil drainage conditions and productivity compared to control plots.
