Mervin St. Luce, Ph. D.

Chercheur scientifique

Mon programme de recherche vise à améliorer la productivité agricole par la mise au point de systèmes de culture durables et résilients, de pratiques de gestion bénéfiques pour améliorer la santé des sols et l’efficacité d’utilisation des éléments nutritifs, en particulier l’azote, et d’outils décisionnels fondés sur des données scientifiques, y compris des modèles de prédiction en utilisant la spectroscopie du sol et l’apprentissage automatique pour l’analyse rapide des sols.
