Ben W Thomas, Ph. D.

Chercheur scientifique – Agroécologie

Mon programme consiste à étudier comment les processus écologiques peuvent être appliqués à la régénération d'agroécosystèmes. Nous traitons chaque ferme, comme une petite planète, pour essayer de la rendre aussi auto-renouvelante que possible et écologiquement efficace.

Recherche et / ou projets en cours

Nous évaluons actuellement le fractionnement du carbone organique du sol dans les divers bassins de matière organique du sol dans des sols modifiés au fumier. C'est une aide pour déterminer le potentiel de séquestration du carbone des sols modifiés au fumier. Nous évaluons également comment la gestion agricole intensive à long terme altère la santé des sols, une réalité à laquelle sont confrontés de nombreux agriculteurs multi-générations du Canada.
