AGRISOM - Investigating the fate of organic compound classes in soil matrix: mineralization vs. preservation patterns in agricultural lands.

Accumulation of organic matter in soil (SOM) improves its fertility and concomitantly limits greenhouse gas emissions. In agricultural lands, SOM is derived from plant litter and manure, but the patterns that underlie the storage of SOM instead of its degradation in response to land management are widely unknown. Plant-derived alkyl and aromatic compounds may play a pivotal role for ecosystem services, such as C storage and soil water holding capacity. The main goal of this project is to unveil how these compounds interact with soil matrix, clay fraction, and microbial community promoting their preservation. To reach this objective, soil samples will be collected from the SOERE ACBB site Lusignan, in which a C3 to C4 plants conversion (prairie to maize cropping) has been established. Physical fractions and aggregates of the soil will be obtained, successively biomarkers for plant and microbial-derived alkyl and aromatic compounds will be isolated from each soil fraction by cutting-edge isolation methods. These compound specific extractions will provide information on the origin and transformation processes affecting organic molecules as well as their residence times and contribution to SOM. Bulk samples, soil fractions, lignin complexes and biomarkers will be analysed by high-resolution techniques of spectrometry (NMR and MS). The ?13C signature will be analyzed for each sample to evidence where the fresh C4 SOM is being accumulated. Finally, the obtained data will be used to test and refine existing theories for molecular SOM dynamics, making possible the design and implementation of tailored policies for land management and enabling realistic predictions of SOM storage/degradation cycles worldwide in the framework of the “4 pour 1000 initiative”.

Biography & research interests

I graduated in Pharmaceutical Chemistry at University of Calabria in Italy. In 2013 I obtained my PhD in “Natural Resources and Agrobiology” at the Institute for National Resources and Agrobiology of Seville (IRNAS-CSIC) in Spain. In 2015, after a prior collaboration, I joined UMR INRA ECOSYS in Grignon, France, thanks to AgreenSkills fellowship. After those 2 years, I worked as R&D coordinator in UpCycle, a startup focused on urban agriculture and circular economy. Actually, I am a postdoctoral researcher at UMR Biogeosciences (University of Burgundy, Dijon, France). I have focused my research activity on soil science, looking at the dynamics of soil organic matter, and carbon fluxes in the agroecosystems. My expertise has been built at the interface between soil chemistry, analytical chemistry, biochemistry, agronomy, and molecular biology. I have been working at a wide range of scales, from landscapes to microcosms, and I have always aimed to use highresolution analytical techniques to unveil the interactions within the soil-plants-water-microbes system. I worked in 6 research centers and one start-up in 5 different countries in the past ten years, leaving a trace of good results for each experience.
