Full textTerrestrial ecosystems currently absorb more than a quarter of CO₂ emissions of anthropogenic origin, thanks to the fertilization effect associated with the increase in atmospheric CO₂. Most of the terrestrial system models used in recent IPCC work estimate that terrestrial ecosystems will continue to behave like a carbon sink of greater or lesser magnitude in the 21st century, depending on the future trajectories of atmospheric CO₂ and climate. Whatever the evolution of atmospheric CO₂ concentration, it remains critical to determining whether enough nutrients (particularly nitrogen) will be available to fully support the increase in primary production resulting from the fertilization effect of elevated CO₂. Most global models of terrestrial ecosystems do not account for the nitrogen cycle and the interactions between the nitrogen and carbon cycles. The latest version of the ORCHIDEE model developed in France incorporates these new features.Using this model, the objective of the thesis will be to analyze the evolution of terrestrial productivity over the recent historical period and to quantify the future development of the productivity of terrestrial ecosystems under the combined effect of these global changes: climate, CO₂ concentration, and reactive nitrogen production evolution, according to different socio-economic scenarios. Including the coupled nitrogen and carbon cycle in ORCHIDEE also requires a better approximation to one key Nitrogen input resulting from Biological Nitrogen Fixation that is currently determined by evapotranspiration. This has been recently invalidated by a meta analysis study. The second objective of this thesis consists then of implementing a process-based dynamic model for reproducing BNF in ORCHIDEE to improve the estimation of the carbon fluxes

Full textIn the context of agroecological transition, the reintroduction of legume crops should play a key role in cropping system sustainability by allowing a reduction of nitrogen (N) inputs. But few references are available concerning the agronomical and ecological services provided by a wide range of legume crops, particularly within crops succession scale. Thus, the main objective of our study is to quantify the N fluxes during and after the legume crops taking into account 10 legume crops (peas, lupin, faba bean, soybean...). Our experiment consists in i) quantifying symbiotic N fixation depending on the amount of soil inorganic N, the mineralisation of N present in legume crop residues after soil incorporation and N losses outside of the soil-plant system (leaching, emission of nitrous oxide), ii) identifying plant biological traits associated to N fluxes. Thus, different N fluxes were quantified during a two-year field experiment, i.e. the first year (2014) legume crops were implanted and followed by wheat the second year (14-15) after incorportation of legume residues. This experiment was repeated in 2016-2017.In parallel, plant root traits were characterised during greenhouse hydroponic experiments

Full textOn Earth, nitrogen can be used by living organisms only if it is "fixed", that is to say if it is present in reactive forms, as ammonia, nitrates, nitrogen oxides or nitrogen chemically tied up to organic molecules. Nitrogen can be fixed biologically or abiotically by industrial processes and by lightning diseharges during thunderstonns. On early Earth, lightning could have been one of the most important sources of fixed nitrogen needed for die emergence of life supplying about 10 [puissance]12 g NO per year. In this work, we report the first experimental simulation of atmospheric nitrogen fixation by electric diseharges, including lightning and corona diseharges, during ail geologic history of die Earth, from an atmosphere predominantly composed of carbon dioxide in die Hadean and Archean to the current oxygenic atmosphere dominated by dinitrogen. This experimental study consists of simulating in laboratory the Earth' s atmosphere from neutral (CO2 - N2) to oxygenic (O2 - N2), of subjecting these gaseous mixtures to irradiation that mimic thunderstorm lightning and corona point-discharges, then of analyzing the nitrogen products by GC-MS-IRTF and also only by infrared spectroscopy. In order to explain the observed variations in the energy yields of NO, NO2 and N2O for each atmosphere and each discharge, we propose chemical mechanisms of formation of these three compounds. The estimates of their annual productions for lightning and corona processes in terrestrial simulated atmospheres allow us to constrain the contribution of electric processes in the abiotic nitrogen fixation, and to examine if the evolution of the atmosphere could have influenced the production of reactive nitrogen available for the living organisms
