Summary of activities

My research activities within the Mixt Research Unit Agronomie are focused on the design of tools and methods for nitrogen management in agricultural systems.

This work is based on the articulation of quantitative methods (modeling) with qualitative methods (innovative design, diagnosis of uses, surveys) to :

  • Produce innovative methods of nitrogen management in agricultural systems
  • Design cropping systems more self sufficient in nitrogen
  • Rethink the collective and/or territorial organization of N management
