Recherche et / ou projets en cours

  • Adaptation du modèle de culture STICS pour la simulation de la croissance et de la valeur nutritive des cultures fourragères pérennes (Fléole des prés et luzerne) dans l’est du Canada
  • Adaptation du modèle IFSM (Integrated Farm System Model) pour la simulation du fonctionnement agronomique, environnemental et économique des fermes laitières du Canada.
  • Assimilation de données de télédétection dans les modèles de culture pour la prédiction régionale des rendements
  • Amélioration des prédictions des modèles de culture en conditions hivernales (couvert de neige, température et humidité du sol, émissions de N2O)
  • Évaluation par modélisation de l’impact des changements climatiques sur les cultures fourragères et le bilan agro-environnemental des fermes laitières
