Dr. Zhang is a Soil Fertility and Water Quality Scientist who conducts research on soil and nutrient management in soil-plant-water agro-ecosystems for maximized crop production profitability with minimized adverse impacts on environmental quality  

Current research and/or projects

  • Innovative management practices for efficient use of nutrients and water and for increase in crop resilience to climate change
  • Legacy soil phosphorus management for improved crop production profitability and soil health with reduced phosphorus loading to Lake Erie
  • Resilient crop-livestock systems – unravelling C and N stabilization and restitution mechanisms in manured soils
  • Validation and delivery of P risk assessment tools at the field and national scale

Research and/or project statements

  • Phosphorus and other nutrients transformations in and transportation from agri-eco-systems
  • Risk assessment of soil phosphorus loss from agricultural lands
  • Efficient use of nutrients from chemical fertilizers and manures/composts for profitable crop production with improved soil health and resilience to climate change and minimized impacts on environmental quality (water & air)
