Themes and common disciplines

Our Joint Research Unit applies the framework and concepts of functional ecology, in order to understand the role of plants and soil organisms (roots, ecosystem engineers, microfauna, microorganisms) and their interactions in determining coupled carbon, nitrogen and phophorus fluxes in soil-plant systems. Our research also focuses on the different ways in which land use change and climate can modify soil-plant system functioning.

Our research activities are structured in 3 research themes and 2 transversal axes:

Soils, Biological Activities and Networks


Theme 1 “Soils, biological activities and networks” sets out to understand the biological processes and interactions involved in C, N and P cycles.

Nutrients and ecological intensification


Theme 2 “Nutrients and ecological intensification” sets out to understand the ecological and biogeochemical processes determining the acquisition and use of nutrients by plants in agroecosystems.

“Carbon & Global Climate Change”


Theme 3 "Carbon and global climate change" sets out to understand the factors and main processes of primary production, carbon sequestration and the sustainability of agrosystems subject to climate change.



The modelling discipline brings together the numerical modelling activities undertaken by scientists on the research themes. It sets out to develop and couple models to improve the simulation of ecosystem functioning.


Once a week Eco&Sols organises a one hour session entitled “Ecology Thursdays” on the ecological approach to the biogeochemistry of soils and agroecosystems. This takes the form of discussions on articles and presentation of research by members of the unit (in particular the students) and by outside lecturers.
