About

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.

Area(s) of Expertise

  • Soil physics
  • Drainage and runoff water quality in connection with farm fertilizer management and soil conservation practices
  • Nitrogen flow monitoring
  • Characterization of farm fertilizers and evaluation of their fertilizing value
  • Agri-environmental development of industrial biomass crops

Related research project(s)

2016-2018 • Field crops

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.

Managing subsurface drainage water to optimize crop productivity, nutrient use, and water availability under current and future climatic conditions

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.

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.
