N2O is a greenhouse gas with high global warming potential and also involved in ozone depletion. Among the greenhouse gases (GHG), N2O is estimated to contribute up to 6% of radiative forcing at the global scale (12 % in France). Agricultural soils appear to be the main anthropogenic source of this gas. The production of N2O by soils primarily occurs through two biological processes (nitrification and denitrification). Different recent publications (Shaaban et al., 2015 ; Hénault and Revellin, 2011 ; Subbarao et al., 2012) have suggested that the use of various natural products or microorganisms can reduce soil N2O emission rates.
The aim of this PhD thesis is to prepare the biotechnical use of different natural products and microorganisms for mitigating GHG emissions by soils. The PhD student will quantify the GHG mitigation potential of different natural products and microorganisms applied to soil samples, and will develop knowledge regarding the microbial and/or biogeochemical mechanisms involved in mitigation.
Supervisor(s):Dr C. Hénault (INRA – AgroEcology) will be the firstname.lastname@example.org
Dr C. Revellin (INRA – AgroEcology) will insure the follow up concerning the microbial approaches and Dr O. Mathieu (UB – Biogeosciences) will insure the follow up concerning the geochemistry approaches
