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
