Research Projects

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.

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.

The aim of this project was to set up a support service to equip producers and others in the industry to improve their irrigation management.

This project aimed to evaluate the purification capacity of different configurations of swales planted with shrubs or perennial grasses to serve as vegetative filter strips.

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 team at IRDA conducted hydrological monitoring on Branch 1 of the Campbell Stream (test basin) as well as the stream’s main branch, which was used as a control.

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.
