Research Scientist

My research focuses on nutrient cycling and minimizing nutrient loss from agriculture. Specifically, I am a phosphorus (P) biogeochemist. I study how P cycles in soil and water, using techniques that range from simple extractions to advanced spectroscopic methods such as 31P nuclear magnetic resonance spectroscopy (P-NMR)  and P k-edge X-ray absorption near-edge structure  spectroscopy (P-XANES). I do my P-NMR work at the Saskatchewan Structural Sciences Centre at the University of Saskatchewan, and my P-XANES work at the Canadian Light Source (CLS) in Saskatoon. Using these advanced techniques, I have examined P forms and concentrations in soils, manure, plants, and snowmelt runoff. This will help to ensure that crops get the P they need, while minimizing P loss to water where it can cause harmful algal blooms.

Current research and/or projects

 Dr. Cade-Menun’s current research investigates agro-environmental health, focusing on soil phosphorus cycling and soil health in Saskatchewan, Manitoba, Quebec and British Columbia.

Research and/or project statements

  • The effect of management practices such as tillage and fertilization on soil phosphorus forms and cycling.

  • Soil acidification from long-tern nitrogen fertilization.

  • Practices that minimize nutrient loss from land to water.
