Soil Science

Brief Biography

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.

Research Interests

Field and laboratory research on soil management strategies to improve soil fertility, productivity and health. Emphasis is on prairie agricultural soils (crop and rangeland), and includes appropriate 4R fertilization practices, effective utilization of manures and other organic amendments, employing new cropping and grazing systems to improve soil organic matter and nutrient cycling.  Novel nutrient and water management practices to maximize efficiencies are developed and evaluated. Means of dealing with problem soils such as salt-affected lands are explored.
