Mr. Mubarak MAHMUD

Mubarak is a PhD student at Laboratory ESE, working under the co-supervision of Laure BARTHES, Stéphane BAZOT, Paul LEADLEY and Nicolas DELPIERRE. He started in November, 2020. The objective of his work is to study the extent of nitrate leaching and the strength of its recovery by trees in agroforestry as well as the different fates of 15 N mineral fertilizer applied to the field. We hypothesize that the deep root of the tree associated with their microbial biomass can retain a part of the fertilizer added to the crop and alleviate the risk of nitrate leaching. He will use several models in combination with observational data to validate his hypothesis.
