Functional Ecology & Soil Biogeochemistry (ECO&SOLS)

Director: Jean-Luc Chotte

 

Research area
Our central objective is to elucidate the role of plants and soil organisms in the functioning of agro-ecosystems and especially in the biogeochemical cycles of carbon and nutrients (with a special focus on nitrogen and phosphorus) in the context of low input agriculture and forest plantations of Mediterranean and tropical areas. The ultimate aim of our research is to translate this knowledge into innovative strategies of ecological engineering of such agroecosystems, while accounting for the major drivers that relate to global changes (climate and land use changes).

Research highlights
Unique, internationally recognized expertise in :
  • soil functional ecology
  • the biogeochemistry of hot spots of biological activities in soils, such as the rhizosphere, the drilosphere, the termitosphere
  • the sequestration of carbon in soils at various scales (from molecular, processes of protection of soil organic matter, to regional balances of soil C)
  • the cycles of nutrients and measuring/modelling of fluxes at the ecosystem level, as well as at the levels of a single plant or a single root

  • Infra red (near and mid) spectroscopy expertise for the investigation of soil chemical, biological and physical properties
  • Mesocosm-Microcosm Platform: growth chambers and greenhouse facilities to conduct plant-based experiments in controlled conditions (however not suitable for manipulating live tropical soils)
  • Soil biology and molecular ecology Platform
  • Soil physico-chemistry Platform
