Impact of integrated pest management on the profitability of field crop farms
This project was aimed at evaluating the impact of integrated pest management on the profitability of field crop farms.
Researcher: Luc Belzile
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
Profitability evaluation of cover crops at the farm level
The project was designed to assess the profitability of various types of cover crops and planting methods at the farm level.
Researcher: Luc Belzile
Economic cost of herbicide resistance in weeds found in field crops
The aim of the project was to estimate the economic impact of herbicide resistance in weeds.
Researcher: Luc Belzile
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.
Researcher: Christine Landry
Development of cover crop techniques and their adaptation to the Estrie region
IRDA was in charge of conducting the economic analysis for this project carried out by Club agroenvironnemental de l’Estrie (CAE Estrie).
Researcher: Luc Belzile
Impacts of green manure on soil structure in the Estrie region
This project was carried out by Club agroenvironnemental de l’Estrie and IRDA was in charge of conducting the economic analysis.
Researcher: Luc Belzile
A diagnostic tool for phosphorus and nitrogen exports (P+N Edit)
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.
Researcher: Aubert Michaud, retraité
Developing new techniques to control water table levels in sphagnum farming
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.
Researcher: Stéphane Godbout
Subsoiling and temporary drainage in soils with low permeability
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.
