Quote: 

"Soils support life – they are the medium in which food is grown to feed people and animals. Soil is alive – it is the home to billions of microscopic and macroscopic creatures that form a rich, diverse foodweb with capacity to sustain ecological health."

Biography: 

Joann K. Whalen is a Professor and James 51³Ô¹ÏÍøProfessor at 51³Ô¹ÏÍø and an Affiliate Professor at the Mohammed VI Polytechnic University (UM6P) in Morocco. She received her Ph.D. from Ohio State University (USA) and worked as a research scientist for Agriculture and Agri-Food Canada prior to joining the faculty at McGill. Dr. Whalen is also a professional agronomist (agronome) in Quebec, Canada. Her research focuses on the soil fertility and soil ecological health of agroecosystems. She has published more than 280 peer-reviewed scientific publications and supervised/co-supervised more than 80 students at the M.Sc. and Ph.D. levels. She teaches courses in soil fertility, nutrient management planning and soil ecology. Joann’s research covers soil biology, soil health and agricultural nutrient management, leading to sustainable and resilient agriculture design, through the implementation of integrated soil and fertilizer management planning, conservation tillage, and diverse rotations that include perennial crops and trees. Currently, she is leading research projects on the plant root microbiome, including microbial and biostimulant products to improve crop tolerance to heat, water and salt stress in the semi-arid regions of Africa.

Current research: 

The Soil Ecology Research Group at 51³Ô¹ÏÍømakes discoveries about the hidden life of the soil, and suggests methods of agricultural management that rely on the natural functions of soil biota to produce food in a manner that is economically sound and environmentally friendly.

Current research projects

Biotic controls on the residence time of soil carbon and nitrogen: new understanding from alternative agroecosystems.

Biological promoters of crop growth and the soil microbiome in agroecosystems.

Best management practices for fertilizer and manure management, to optimize the soil nutrient supply and reduce greenhouse gas emissions.

Valorization of organic residuals from industries and municipalities.

Fundamental research towards a better understanding of the spatio-temporal dynamics of biogeochemical cycling in the soil-plant-atmosphere-water continuum.

SOIL 535. Soil Ecology.

Credits: 3
Offered by: Natural Resource Sciences (Faculty of Agric Environ Sci)
Terms offered: Fall 2025
View offerings for in Visual Schedule Builder.

Description

Exploration of the unique soil habitat for organisms with a focus on the variables that affect the abundance, diversity and interactions of soil biota and, in turn, their influence on soil physicochemical properties, biogeochemical cycles and other factors impacting ecosystem sustainability. Topics include survey of soil fauna, soil food webs, microbial ecology, biological carbon and nitrogen cycling, plant-soil interactions, and the effects of human activities and management on soil ecology, including synthesizing concepts and a critical analysis and interpretation of primary scientific literature in soil ecology.
  • 3 lectures and one 3-hour lab
  • Prerequisite(s): ENVB 210 or GEOG 305 or SOIL 326 or permission of instructor.
  • Restrictions: Not open to students who have taken SOIL 335.
