Current research topics

The main topic of my research is dynamics and management of nitrogen (N) in cropping systems. I am interested in understanding biochemical cycles in soils and contributing to mitigation of N emissions to the environment. I help design agroecological systems by building decision-support systems (DSS) with end-users.

My initial research work focused primarily on understanding and modelling soil C and N fluxes after spreading of organic manure and other products, by relating their biotransformation to their composition. I am now interested in combining researchers’ and end-users’ knowledge to build DSS. In this way, with a team of researchers and engineers, we have developed the software Syst’N with its end-users.
It is based on a simple dynamic N model and aims to:

  • quantify N losses in cropping systems
  • allow extension service advisers to estimate N losses
  • contribute to the design of environmentally friendly agricultural systems.

I work on DSS and indicator properties to help farmers drive their production systems towards agroecology and sustainability.

Current projects
  • Syst’N®: The software Syst’N aims to estimate N losses in cropping systems and help advisers and farmers find ways to improve management of N in their systems.
  • Agro-éco-Syst’N: Identification of agroecological cropping systems with low N losses using the assessment tool Syst’N® (2017-2020)
  • TI Terres de Sources – Workpackage 2.2.: Supporting farmers towards agricultural systems that improve water qualit (2020-2022)
  • EIDER: Resilient grazing and fodder systems (2020-2022)
