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

Marc-Olivier Gasser currently heads up the largest agricultural soil health study conducted in Québec since 1990.
