Nutrients and Soil Management

Current research and/or projects

My research program focusses on soil and nutrient management. My current projects aim at improving our understanding of nutrient cycling and dynamics, particularly phosphorus, in field crops and berry production systems. More specifically, I collaborate with colleagues across Canada and local industry to improve starter fertilizer P recommendations in silage corn systems and to adapt a simple agri-environmental indicator of the risk of P transfer from fields to water sources for soils of British Columbia.


Research and/or project statements

  • Role of legacy P in Agriculture
  • Refining starter fertilizer P recommendations for silage corn in British Columbia
  • Interaction between bioactivators and low starter fertilizer P blend on soil P availability and desorption kinetics
  • Adaptation of a simple agri-environmental P saturation index for soils in British Columbia
  • Development of high performing growing media through partial substitution of conventional growing media with biochar and vermicompost
  • Improving soil health through alley cover crop management in raspberry planting
  • Understanding the role of acidifying nitrogen fertilizers on yields and soil chemical properties in blueberry planting
