Agro-ecosystem modeling

Current research and/or projects

  • Adaptation of STICS crop model for simulating perennial forage crops growth and nutritive value in eastern Canada
  • Adaptation of the Integrated Farm System Model (IFSM) to simulate the agronomic, environmental and economic performance of Canadian dairy farms
  • Assimilation of remote sensing data into crop model for regional yield predictions
  • Improving crop model predictions under winter conditions (snow cover, soil temperature and moisture, N2O emissions)
  • Simulation of the impact of climate change on forage crop growth and agro-environmental balance of dairy farms
