Parcours
Habilitation à Diriger des Recherches Sciences Agronomiques (2002, Institut National Polytechnique de Lorraine)
Docteur en Sciences de la terre, Université Marseille (1988, Université Aix-Marseille III)
Recherches et compétences
Etude, analyse et modélisation du fonctionnement biogéochimique du cycle phosphore dans les agrosystèmes. Conséquences sur la nutrition des cultures et évaluation fonctionnelle et mécaniste de la disponibilité du phosphore du sol vis-à-vis des espèces cultivées. Les agrosystèmes privilégiés sont les sols cultivés sous grandes cultures en couvrant une gamme large de type de sol et de pratiques agricoles (absence d’intrants, recyclage de matières fertilisantes organiques, engrais minéraux, sans-labour). L’échelle d’étude temporelle principale est la décennie voire plusieurs décennies abordée à travers l’analyse diachronique d’essais au champ.
Projets en cours
Description fonctionnelle et mécaniste de la disponibilité du P du sol pour les espèces de grandes cultures. Mise en équation et prévision de la dynamique à long terme du P disponible du sol et du devenir du P apporté en fonction des types de sol et de la nature de la fertilisation phosphatée
Minéralisation à long terme du phosphore organique du sol en fonction de l’épandage de produits organiques résiduaire et d’engrais minéraux
Les déterminants physico-chimiques du transfert des ions phosphate diffusibles à l’interface solide-solution de sols cultivés en France
