MARTIN-LAURENT Directeur de Recherche, INRA, Dijon Co-directeur de thèse Dedication I dedicate this dissertation to my family, who always motivated and encouraged me to fulfill my dreams, and especially…. to my mother for her unconditional love to my Father who is no more with us, but still live and walk beside us everyday, ‘unseen, unheard, but always near, still loved, still missed…. 2 Acknowledgements Acknowledgements It is only just to mention the fact that it would not have been possible to write this Doctoral Thesis without the support and help of many good people around me, to only some of whom a particular mentioning is possible in this humble gratitude. First and foremost, I pay utmost gratitude to my supervisor Dr. Laurent Philippot, whose encouragement, and radiant guidance made this thesis a reality. He served as an inspiration to me as I hurdle all the obstacles in the completion of this research work. His undying efforts and experience paved my way through the difficult and tiresome path of research. Despite his tight schedules, he always provided me substantial guidance and valuable suggestions throughout my PhD, and never stopped inspiring me for hard work. Without his kind supervision my thesis would have remained just a dream for me. I would like to extend my heartiest gratitude to my co-supervisor Dr. Fabrice Martin-Laurent, for his dynamic and intellectual supervision. Indeed, it was an honor for me to work under his supervision. I am thankful to him for sharing his extensive experience and knowledge and appreciate his support throughout my time here. I am grateful for his keen interest in my research work and constructive suggestions which served as a beacon of guidance for me. I wish to extend my thanks to Dr. Philippe Lemanceau, director of Agroécologie (INRA, Dijon) for welcoming me and providing me with a great opportunity to work in this prestigious research laboratory. I express my feelings of most sincere gratitude and devout appreciations to all the jury members, Emile Benizri, Francis Douay, Jean Guzzo and Christophe Schwartz for taking out time from their busy schedules in accepting and evaluating my research work and for the comments and suggestions that will help to improve the quality of this work and also my approach towards the overall research work. I share the credit of my work with Jean Claude Germon, Aymé Spor and Romain Barnard for their thoughtful comments and valuable suggestions in the thesis write-up. I thank Chris for helping in PDA data analyses and especially Aymé for the assistance in statistical analyses. I would like to extend gratitude to Christophe Schwartz and Alain Brauman for taking out time as the members of ‘Comité de Pilotage’ and for their valuable suggestions. Thanks also to Jérôme Cortet and Geoffroy Sere for time to time assistance and useful discussions which helped me to understand the work on Technosols. My deepest thanks to Jérémie, David, Marie-Christine and Florian for their valuable assistance and help to learn various methods I needed to perform. I am grateful to Nadine, Marion, Frederique, Géraldine, Abdel, Najoi, Chloé, Ines, Fiona, Aude, Anthony, Irène, Koki, and all other fellow research members at INRA, Dijon for their affectionate attitude, valuable suggestions and best cooperation throughout my stay in the lab. I feel privileged to have worked in the cooperative and encouraging environment of this laboratory, which enabled me to succeed in my research endeavors. I cannot forget the invaluable support of Sabir especially during my early days in the lab. I owe my deepest gratitude to the Higher Education Commission (HEC) Pakistan, and the Doctoral School of the University of Burgundy (France) for their financial and academic sponsorship of my PhD. Thanks to SFERE also. This PhD was part of the ‘Biotechnosol program’ coordinated by Dr J. Cortet, carried out as part of the Gessol program ‘Fonctions environnementales des sols et gestion du patrimoine sol’ funded by the French Ministry of Ecology in cooperation with the ADEME. I would like to thank the technical staff of the 3 Acknowledgements Laboratoire Sols et Environnement, as well as the GISFI. I extend my gratitude to all the individuals and organizations that have directly or indirectly helped me throughout my work. To HEC thank you again for providing me an opportunity to carry on my doctoral studies in France by awarding me the PhD scholarship grants. I am indebted to my longtime friends who deserve recognition here for their friendship, those in Pakistan including Baqa, Maqshoof, Danish, Khuram, Iftikhar, Malik, Fani, Imran, Asif, Shakil and Usman and also those in Dijon including Anees, Ashfaque, Sabir, Amjad, Hamid, Ali, Farasat, Sajjad, Atif, Abid, Ahmed, Ahsan, and Shamsheer for their enthusiastic attitude, and moral support during my entire academic pursuit. Time spent in Dijon will be remembered for ages (Sajjad and Atif can better express). Again, I would like to thank all other friends in France and in Pakistan with whom I had a nice time. Finally, thanks to my family, for their love, support, prayers for me and encouragement over the years throughout my studies. No acknowledgements could ever adequately express my obligations to my affectionate and adoring parents, brothers and sisters for their amicable attitude and love, mellifluous affections, inspiration, well wishing and keen interest which hearten me to achieve success in every sphere of life. I cannot find words in acknowledging that all the credit goes to my beloved father, who is no more with us but without his support, the present distinction would have been merely a dream. Sweet memories of my loving father are always encouraging me in hard and harsh times. Last but by no means the least, I praise God Almighty whose blessings and glory flourished my thoughts and Who gave me courage and health to finalize my study. FARHAN HAFEEZ 4 Résumé Résumé L'augmentation de la dégradation des sols et ses conséquences sur les services écosystémiques nécessite le développement de stratégies de restauration de ces sols. La constitution de Technosols, résultant de l’assemblage de sols pollués et de déchet industriels, est une approche innovatrice pouvant à la fois permettre de restaurer les sols et de recycler des sous- produits industriels. Des études récentes ont mis en évidence que les Technosols pouvaient assurer des services écosystémiques tels que la production primaire. Toutefois, notre connaissances des autres services écosystémiques rendus par les Technosols tels que les cycles biogéochimiques est limitée. En raison de la contribution significative des communautés microbiennes aux cycles biogéochimiques dans les sols, l’objectif de ce travail de thèse était l’effet du type de Technosol sur les communautés microbiennes et plus particulièrement les communautés fonctionnelles impliquées dans le cycle de l’azote. Dans ce contexte, (i) la densité et la diversité de la communauté bactérienne totale, (ii) la densité de la communauté crenarchéenne ainsi que (iii) la densité et les activités des communautés nitrifiante et dénitrifiante ont été étudiées dans deux types de Technosols différents. Les résultats obtenus montrent que la diversité et la composition de la communauté bactérienne des deux Technosols n'étaient pas significativement différentes entre elles, et similaires à celles de ‘sols naturels’, les Proteobacteria étant le phylum dominant (50-80%). La densité de la communauté bactérienne oxydant l’ammonium était non seulement plus importante que celle des crenarcheae qui oxyde l’ammonium, mais est également corrélée avec l'activité potentielle de nitrification suggérant ainsi que les bactéries sont responsables de l’oxydation de l’ammonium dans les Technosols.

However, the current rates of soil usage and degra- dation have led to a loss of soil for agriculture, habitats, biodiversity, and to ecosystems problems. Urban and former industrial areas suffer particularly of these problems, and compensation measures to restore environmental quality include the renaturation of dismissed areas, de-sealing of surfaces, or the building of green infrastructures. In this framework, the development of methodologies for the creation of soils designed to mimic natural soil and suitable for vegetation growth, known as constructed soils or technosols, are here reviewed. The possible design choices and the starting materials have been described, using a circular economy approach, i.e., preferring non-contaminated wastes to non-renewable resources. Technosols appear to be a good solution to the problems of land degradation and urban green if using recycled wastes or by-products, as they can be an alternative to the remediation of contaminated sites and to importing fertile agricultural soil.

  • A Geochemical and Agronomic Evaluation of Technosols Made from Construction and Demolition Fines Mixed with Green Waste Compost
    agronomy Article A Geochemical and Agronomic Evaluation of Technosols Made from Construction and Demolition Fines Mixed with Green Waste Compost Malcolm Coull, Benjamin Butler , Rupert Hough and Luke Beesley * The James Hutton Institute, Craigiebuckler, Aberdeen AB158QH, UK; [email protected] (M.C.); [email protected] (B.B.); [email protected] (R.H.) * Correspondence: [email protected] Abstract: Construction and demolition fines (C&D-fines) and green waste compost (GWC) are two commonly generated urban waste materials that represent repositories of geochemical value. Here technosols were produced from volumetric mixtures of these materials ranging from 0–100% C&D- fines, with the remaining proportion comprised of GWC. Agronomic assessment was carried out by way of pot and rhizobox plant growth experiments with ryegrass, barley and pea to determine germination, plant mass and rooting behaviours. Geochemical and mineralogical evaluation was achieved by soil pore water solution measurements combined with X-ray powder diffraction analyses respectively, to characterise the technosols and their distinct deviations from a reference agricultural geogenic soil (soil). The results demonstrated that germination, growth and root mass/surface area of vegetation were up to 80-fold greater after 30-days in the technosol composed of equal volumes of the two materials (50% C&D-fines: 50% GWC) compared to the soil. High concentrations of Ca and Citation: Coull, M.; Butler, B.; Mg in pore waters (550–800 mg·L−1) were dominant features of the technosols, in contrast to the soil Hough, R.; Beesley, L. A Geochemical (<50 mg·L−1), resulting from gypsum and calcite enrichment of the C&D-fines.

  • Predictability of the Evoluon of the Soil Structure Using Water Flow
    Special Section: Predictability of the Evolu on Soil Architecture and Function of the Soil Structure using Geoff roy Séré* Water Flow Modeling for a Stéphanie Ouvrard Vincent Magnenet Constructed Technosol Benjamin Pey This paper focuses on the rela on between the structure of a constructed Technosol and its hydraulic characteris cs during its early pedogenesis. The method is based on a 3-yr Jean Louis Morel comparison of, on one hand, experimental measurements from an in situ gravita on Christophe Schwartz lysimeter and, on the other hand, a modeling approach with HYDRUS-1D. The change of water fl ow pa erns with me was described. It was consistent with previous results for constructed Technosol aggrega on. Apart from seasonal varia ons, the specifi city of the hydraulic func oning of the constructed Technosol was shown to be due to the nature of its technogenic parent materials. The in situ evolu on of the hydrodynamics has been established and partly linked to external factors (climate, vegeta on). The direct modeling and the op miza on of the parameters over fi rst a 3-yr period and then three 9-mo periods accurately represented global water fl ow trends at the pedon scale. However it failed to simulate precisely the main events, such as massive leachate ou low. An evolu on with me of some of the hydraulic proper es was shown, expressing the structuring of the soil. The existence of two dis nct me-scales (slow and steady/fast and cyclic) of the evolu on of hydraulic parameters was then formulated as a new hypothesis.
