About

Christine Landry (agr., Ph.D.) earned a doctoral degree in renewable resources from the Faculty of Agricultural and Environmental Sciences at McGill University in 2009. She also holds a bachelor's degree in biology from Université de Sherbrooke, a bachelor's degree in agronomy (specialization in soils and the environment) and a master's degree in the physiology of crop yields from Université Laval. From 1993 to 2002 Christine held various research-related positions at Université Laval, including at the horticultural research centre, and as a teaching assistant in the agronomy department laboratory. She has a keen interest in teaching, and every summer she hosts internships for students seeking their first experience in agri-environmental research. Christine has been employed at IRDA since 2003 as a researcher in chemistry and soil fertility. She works on the preparation of fertilization reference charts and the development of control protocols for optimizing soil fertility and biomass conversion.

Area(s) of Expertise

  • Soil chemistry and biology in connection with nitrogen and phosphorus soil fertility (dynamics of N and P, P specialization, mycorrhizal action)
  • Fertilization charts
  • Soil conservation practices
  • Biomass conversion (slurry, treated slurry fractions)
  • Nutrient dynamics under irrigation

Christine Landry works on the preparation of Québec’s fertilization reference charts and the development of protocols for optimizing soil fertility and biomass conversion.

Organic broccoli
2019-2021 • Market gardening

A comparative study of organic fertilizers with a high, effective nitrogen to total phosphorus ratio (Neff / Ptot) as a basis for developing productive and sustainable market gardening fertilization strategies

In this study, we will test alfalfa meal pellets in a broccoli crop planted on plastic-covered irrigated mounds and we will compare them with two organic fertilizer, in addition to a control treatment in which no nitrogen is added.
