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.
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.
Researcher: Christine Landry
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.
Researcher: Christine Landry
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
Field tests on the nitrogen efficiency coefficient and nitrogen release period of pelleted laying hen manure on grain corn and oat crops
This project will determine the nitrogen efficiency coefficient (EC) of pelleted laying hen manure, a source that is interesting an increasing number of growers, both organic and conventional, because of its efficiency.
Researcher: Christine Landry
Revising the MAPAQ fertilization reference charts
IRDA—in its capacity as the authorized representative tasked with revising the MAPAQ fertilization reference charts—will plan, coordinate, and monitor all activities involved in updating these charts.
Researcher: Christine Landry
Banded controlled-release and conventional fertilizer in horticultural production under plastic mulch
The aim of this project was to field-test sound irrigation practices and band application of various types of fertilizers at ridging time to eliminate fertigation and increase the efficiency of fertilizer and water use under plastic mulch.
Researchers: Carl Boivin Christine Landry
Effectiveness of an annual vs. end-of-season legume green manure crop in increasing soil resilience and providing sufficient nitrogen
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.
Researchers: Aubert Michaud, retraité Marc-Olivier Gasser Maryse Leblanc
Developing a nitrogen fertilization program based on green manure supplemented by a manure-based starter fertilizer in organic grain production
In a wheat/grain corn/soya rotation, green manure can be used to obtain profitable organic grain corn yields while limiting phosphorus pollution.
