Parcours

Bakker MR. 1998. ‘Effet des amendements calciques sur les racines fines de chêne (Quercus petraea et robur) : conséquences des changements dans la rhizosphère’. Doctorat en Sciences du Sol, Université Nancy I.

Bakker MR. 2012. ‘How to get the nutrients into the trees?’ Habilitation à Diriger les Recherches, Université de Bordeaux.

Recherches

Mes activités de recherche portent sur la biodisponibilité des éléments minéraux et prélèvements par des arbres et ou espèces présentes dans le sous-bois. Les modèles d’études sont surtout des forêts mono-spécifique ou mixtes, avec parfois des comparaisons avec d’autres milieux (prairies) et / ou l’étude des apports de fertilisants ou amendements sur ces systèmes. Les approches incluent l’étude de stocks et flux de minéraux dans le sol, des systèmes racinaires, de leurs partenaires symbiotiques voire de la communauté microbienne du sol.
