Research interests
I am a soil scientist, who aims since my graduation to evaluate cultural practices impacts on soil biogeochemical (C, N, P) functioning, with a specific interest for tropical soils since 2016. I especially focus on how plant diversity and residues restitution management impacts on soil organic matter dynamics.
To do so, I lean on multidisciplinary approach combining indicators of soil properties (physical, chemical and biological), soil organic matter composition and plant communities’ traits.
My goal is to propose new elements of understanding of the determinants of soil C stabilization in a wide range of tropical agroecosystems, in order to feed simple decision rules and models on suitable practices to the local context of the agroecosystem.
