2023 CSSS Fellow Award to Dr. Tiequan Zhang

Dr. Tiequan Zhang is a Senior Research Scientist at the Agriculture and Agri-Food Canada Harrow Research & Development Centre. He received his Ph.D. in Soil Chemistry and Fertility from McGill University in 1996 and has made significant contributions to soil management, crop production, and water quality. Tiequan is a nationally and internationally recognized authority on nutrient management in agri-ecosystems and was a pioneer in the development of the concepts of legacy phosphorus (initially referred to as “residual phosphorus”) in soils and sub-surface phosphorus loss pathways—both rooted in his Ph.D. studies during mid-late 90’s. Tiequan’s career has focussed on giving Canadian agronomists and farmers the right information to produce an abundance of nutritious food with innovative practices that also conserve soil and protect water quality.
Tiequan has disseminated his research actively and broadly to academic communities, farming groups, crop advisers and policymakers. He has authored or co-authored over 140 publications in peer-reviewed scientific journals and 480 technical reports and presentations at various meetings.
Tiequan has been an Adjunct Professor/Special Graduate Faculty at the University of Guelph since 2007 and at the University of Windsor since 2013. He has served on numerous regional, national, and international professional societies/committees, including the National Nutrient Recovery and Reuse Steering Committee (Canada), Advisory Board for the Phosphorus Sustainability Alliance in North America, Planning and Priority Committee on International Joint Commission Lake Erie Cooperative Science and Monitoring Initiative, and serving as Vice-President for the International Society on Environmental Indicators. Tiequan is a Fellow of the American Society of Agronomy and the Soil Science Society of America and is a recipient of the Agriculture and Agri-Food Canada Gold Harvest Award.
