Professionnel de recherche

Assister le chercheur principal dans la réalisation de projets de recherche en lien avec la valorisation des matières résiduelles fertilisantes (compost, biosolides papetiers, biochars) en agriculture et la fertilisation N et P des grandes cultures.

Recherche et / ou projets en cours

1. Effet de l'application combinée de biosolides papetiers et de biochar sur la mycorhization, la nutrition minérale et le rendement du maïs et du soya

2. Évaluation à long terme de l'application de biosolides papetiers et de produits chaulants sur le rendement et la qualité des cultures et les propriétés du sol

3. Effet à long terme du travail du sol et de la fertilisation en N et P sur une rotation maïs-soya
