Research Projects

This project aims to examine whether improving soil health can help check strawberry decline.

The current project is designed to check the predictability of the biological productivity score.

Economic analysis of a three-year project aimed at testing methods of reducing and correcting surface soil compaction.

The aim of this project is to show that efforts made to better distribute phosphorus on the land are effective and that the indicators used to determine phosphorus saturation thresholds are correlated with soil phosphorus balance and dynamics.

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.

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.

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.

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.

The project consists of evaluating soil degradation based on representative samples taken in Québec’s main soil regions and parent materials.
