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.

Impact of manure management and tillage practices on water quality and safety in canola and wheat

Canola and wheat (wheat-corn-canola rotation) were planted in 2016 and 2017, respectively, on 12 experimental plots with tillage practices on the main plots (minimum tillage and chisel plow) and fertilization methods (mineral fertilizers, 25 m3/ha of pig manure and 50 m3/ha of pig manure) in the subplots.
