Jeff Schoenau
Professor

Dr. Jeff Schoenau is a professor of soil fertility and professional agrologist who works in the Department of Soil Science at the University of Saskatchewan. He holds the Saskatchewan Ministry of Agriculture Soil Nutrient Management Chair in the College of Agriculture and Bioresources, and is a fellow of the Agricultural Institute of Canada. He was born in Saskatchewan, raised on the family farm near Central Butte, and completed his undergraduate and graduate degrees in the College of Agriculture at the University of Saskatchewan. He continues to be involved in farming with his wife Lynne.

Soil Science

My research interests include nutrient cycling and management, soil fertility and fertilizer use, plant nutrition, soil conservation, quality and land use, cropping systems, herbicide fate and interaction in soil. The focus of my research is to provide information and tools that can be used to best manage the soil fertility resource, thereby ensuring economic and environmentally sustainable use of inorganic and organic nutrients (mineral fertilizers, manures and other organic amendments) that enhance crop and livestock production. The goal is to conduct research to provide innovative solutions for soil nutrient management that will increase profitable crop production and ensure soil and environmental quality. Knowledge derived from my research activities is disseminated to the scientific community and industry, and used to develop management guidelines, recommendations and tools for sound soil and nutrient management.
