Current research and/or projects
Current research projects focus on soil health, soil erosion and productivity, soil reclamation, beef feedlot manure management, organic amendments, and dryland and irrigated cropping systems.
Research and/or project statements
1. Integrating multiple beneficial management practices (BMPs) in organic cropping systems: Soil health, weed and insect interactions.
2. Assessment of occurrence of synthetic hormones (melengestrol acetate & trenbolone acetate) and beta agonist (ractopamine) in cattle operations and associated environments.
3. Optimizing agroecosystems resiliency – Systems productivity, resilience and sustainability in the major Canadian ecozones.
4. Use of legume crops to enhance N use efficiency, carbon sequestration, soil health and soil biodiversity in three ecoregions chosen to represent the different climatic conditions of Canada.
5. Resilient crop-livestock systems – Unravelling C and N stabilization and restitution mechanisms in manured soils.
