Marc-Olivier Gasser (agr., Ph.D) is an agronomist. He earned a bachelor's degree in bio-agronomy (1987), a master's degree in soils (1991) and a doctorate in soils (2000) from Université Laval. During his time as a researcher at Université Laval from 1988 to 2004, he acquired considerable expertise in a number of areas, including soil science, soil conservation, livestock manure recycling, and water quality in agricultural settings. He then moved on to Agriculture and Agri-Food Canada as a postdoctoral fellow in 2005. In 2006 Marc-Olivier joined IRDA as a researcher, where he focuses on the management of soils, water, and organic fertilizers.
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.
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.
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.
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 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.
The project consists of evaluating soil degradation based on representative samples taken in Québec’s main soil regions and parent materials.
