Full textLes objectifs de ce travail étaient de comprendre et de quantifier à l'échelle d'un paysage bocager, l'effet du système talus/haie sur l'organisation des sols et sur les stocks de carbone organique associés, ainsi que de décrire la dynamique des processus spatiaux qui ont conduit aux organisations observées.
Pour y parvenir, la démarche adoptée a combiné trois approches complémentaires. Tout d'abord, nous avons conduit une étude de terrain dans un paysage bocager historiquement documenté et offrant des conditions topo-paysagères contrastées avec pour but une caractérisation spatiale de l'effet du réseau bocager qui prenne en compte l'action de l'homme et la nature tridimensionnelle de la couverture pédologique à l'échelle du paysage.
Ensuite, nous avons couplé des approches de datation relative (analyse de documents historiques et géométrie des horizons) et absolue (carbone-14, césium-137), complémentaires des approches spatiales, pour dater les sols et analyser la dynamique des processus à l'origine des modifications de leur
organisation spatiale.
Cette prise en compte de la dimension temporelle était nécessaire pour améliorer notre compréhension des processus de redistribution en sol et nous permettre d'engager une modélisation spatiale et temporelle simulant des évolutions du paysage bocager en fonction de différents scénarii d'occupation des sols.

Full textThe effect of hedgerow network on soil organisation at landscape scale is still unclear as most studies have been done in 2D focusing on situations with hedges perpendicular to the steepest slope. Therefore extrapolation at the whole landscape induces a wrong estimation of the hedgerow network effect at the landscape scale. Aims of this study were to understand and quantify at landscape scale, the effect of the hedgerwo network on soil organisation and on asociated soil organic carbon stocks and to desribe the dynamic of spatial processes responsible for these organisations. The adopted strategy has combined three complementary approaches. First a field study was carried out in an hedgerow network landscape historically documented, having contrated topographical and landscape situations. This in order to obtain a spatial caracterisation of hedgerow networks which take into account human activities and three dimensional nature of the pedological covre at landscape scale. We combined relative dating approaches (analysis of historical documents and of soil geometry) and absolute dating technique (14-carbon, 137-Caesium), complementary to the spatial approaches. These techniques allowed us to date the organo-mineral horizons of the soil cover and to analyse the dynamic of processes responsible for modifications of the soil spatial organisation

Full textRecent results have shown that equatorial podzols store large amounts of carbon in their deep Bh horizons. This leads to two main questions: (1) how and at what kinetics these soils were formed, (2) how climate change could induce atmospheric carbon production that could impact the global climate system.In this context, we have developed a model that allows to constrain carbon fluxes both by the observed C stocks and their 14C age. In a sufficiently simplified situation, we have established a formal relationship between the C stock evolution and its 14C age. Applied to Amazonian podzols, our model has brought new and unexpected results. It has been shown that the surface horizons of the most hydromorphic podzolized areas are the largest contributors of MOD transferred to the hydrographic network then to the sea. It is observed that the formation of Bh is only possible by considering two compartments, fast and slow. The estimate of their formation time (low estimate) allowed to differentiate between relatively young podzols (formation time 15 – 25 ky) developed on relatively recent Holocene sediments and old podzols (formation 180 – 290 ky) developed on older sediments. The carbon accumulation rate in the studied podzols ranges from 0.54 to 3.17 gC m-2 y-1, which corresponds to a carbon sequestration around 3 1011 gC an-1, which is significant at the geological scales.Column percolation experiments allowed us to show the reactivity of the Bh material and the presence, despite very high C/N ratios (63 on average), of a significant bacterial activity which modifies the nature of the MOD which percolates through it. This MOD has the capacity to transport Al and Fe in the form of complex organometallic complexes capable of migrating through very kaolinitic materials. These results contribute to the understanding of the transfers of pedologically formed MOD in the deep aquifers.Under the hypothesis of the appearance of a climate with contrasting seasons, we have been able to show that a 90-day period without rain after the disappearance of the perched water-table would not allow to reach the point of entry of air by drying of superficial horizons. Nevertheless, assuming an air entry, the extrapolation of the experimentally measured mineralization rates under oxic conditions results in a production of atmospheric C around 2.0 1014 g of CO2 per year, which may involve a positive feedback from the global climate system

Full textCarbon dioxide sequestration in plant and carbon storage in soil and biomass could be considered as a complementary solution against the increase in concentration of gases responsible for climate change. The aim of this work is to understand the mechanisms of organic matter stabilization in the deepest horizons of soils. The influence of landuse, minerals and amendment with organic matter (compost) on the carbon dynamic has been studied. Four soils representing different landuses (grassland, forest and arable soil) were characterized. The organic matter decreases in amount with depth and becomes more refractory. The relatively high amount of organic matter in deep horizons is probably related to the strong presence of clays and to the low biological activity. The different vegetations seem to influence strongly the quantity of soil organic carbon while affecting slightly its quality. Indeed, the structural study of organic matter shows weak differences whereas the amount of carbon and lipids are more important in arable soil. The study of organomineral associations revealed that the bacterial contribution is more important in fine fractions. Amendment with organic matter of an arable soil affects the biological activity and improves its structural stability. The distribution of the different forms of organic matter has been modified and the presence of molecules originating from the compost in lipids and humic substances show an incorporation of exogenous carbon

Full textAgroforestry is a land use type where trees are associated with crops and/or animals within the same field. This agroecosystem could help mitigating climate change, and also contribute to its adaptation. The goal of this thesis was to evaluate the potential of soil organic carbon storage under agroforestry systems. This study was performped at the oldest experimental site in France, a trial supervised by INRA since 1995, but also at farmers' fields. Soil organic carbon stocks were compared between agroforestry and agricultural plots, down to 2 m soil depth. All organic inputs to the soil were quantified (tree roots, leaf litter, crop roots and residues). The stability of additionnal stored carbon was caracterised with soil organic matter fractionation, and soil incubations. A model of soil organic carbon dynamic was described in order to better undrestand this dynamic in agroforestry, especially in deep soil layers. This study revealed the interest and the potential of agroforestry systems in increasing soil organic carbon stocks, with accumulation rates of 0.09 to 0.46 t C ha -1 yr -1. It also reveals the role of tree rows in this storage, and the importance of carbon inputs from root mortality. However, it raises concerns about the stability of this storage

Full textSoils are the largest terrestrial pool oforganic carbon and thus play a key role in mitigatingclimate change. The urban soils account for 3% of theworld’s territory and urbanization is currently theprimary cause of land use change. The increase ofartificial areas have led to a growing interest in theurban soil ability to store organic carbon. This workaimed to understand the contribution of urban soils tothe global organic carbon stock and to propose astandardized method for its monitoring. The researchalso focused on studying the stability of organic carbonin urban soils and modeling its dynamics. A databasewas built using data available at the French territorylevel as well as using additional measurements acquired in three French cities.The organic carbon stock in urban open soils aresimilar between cities, and equivalent, or even higherin depth, than that of surrounding forest soils. Thestock in open soils is particularly dependent upon themanagement methods of the urban green spaces,and on the specific site history. Thus, open urban soilsare characterized by a high proportion of labileorganic matter at 0-44 cm depth. Conversely, sealedsoils have very low carbon stocks. They arecharacterized by a high proportion of stable organicmatter whose evolution (storage or mineralization)depends on the dormant state of the microbialcommunities. A conceptual model of carbon dynamicsfor these two soil types has been developed. Finally,recommendations for optimizing carbon monitoringand urban soil management have been proposed

Full textTo understand the fate of stable soil organic carbon (SOC) in a warmer world is a major challenge to be able to predict future atmospheric CO2 concentrations. To do so, it is of prime importance to understand what the stable SOC is exactly and how its mineralization rate is modulated by temperature. This thesis proposed to study (1) the temperature sensitivity of stable SOC mineralization; (2) the response of soil microbial communities to temperature and (3) to establish a link between SOC decomposability and its age. Soil samples from four long term bare fallow experiments were used for work. We incubated soils sampled at the beggining of each experiment and after several decades of bare fallow at different temperatures for 427 days and we regularly monitored soil respiration. At the end of the incubation, soil microbial communities were assessed using pyrosequencing techniques. Finally, we determined the age of soil organic carbon by radiocarbon dating in soil samples from the chrono-sequence located at Versailles, France. The results obtained brought evidence for a general relationship between the mineralization rate of soil organic carbon and its temperature sensitivity. We also found that microbial communities linked to stable organic carbon are more diverse but also more sensitive to a temperature increase. Some bacterial phyla were particularly impacted by the temperature increase and the organic resource rarefaction. Finally, this thesis highlighted the difficulties met with the radiocarbon dating technique

Full textCarbon dioxide super critical extraction is applied to the remediation of soils contaminated by organic compounds. We have studied three aspects of the extraction process: 1) The calculation of solubility of organic compounds in super critical fluids. W e proposed a thermodynamic model which is based on the relations existing between the Helmholtz energy of pure components and the excess Helmholtz energy in a mixing process at constant packing fraction. The components may intervene in the equation of state of the mixture with varied equations of state. This model was applied to solid-fluid and liquid-fluid equilibria. A group contribution method was developed for hydrocarbon-carbon dioxide mixtures. 2) The adsorption equilibrium of biphenyl in soil in the presence of super critical carbon dioxide was studied experimentally and represented with the Bragg Williams lattice model. The adapted model allows adsorption calculation for a given set of temperature-pressure-fluid composition 3) For the kinetic study of the extraction, we used a soil artificially contaminated with biphenyl. In the soil, the pollutant is distributed between a precipitated phase and an adsorbed phase. Thus, the extraction model contains a dissolution kinetic term and a desorption kinetic term. The model parameters (the dissolution rate coefficient, the overall mass transfer coefficient between soil particles and the fluid and the fraction of precipitated biphenyl from the total quantity in soil) was estimated by fitting with experimental extraction data
