| Le sol, composante du Terroir doit être considéré comme une ressource non renouvelable essentielle au fonctionnement des agro‐écosystèmes. Or, les sols viticoles sont particulièrement vulnérables aux dégradations. L’objectif central de ma thèse est donc d’évaluer comment les pratiques viticoles affectent la qualité des sols dans le Languedoc‐Roussillon. Pour ce faire, j’ai d’abord évalué la qualité des sols sur 164 parcelles présentant une grande variabilité de pratiques culturales et réparties sur 9 zones pédologiques très diversifiées. Puis, j’ai évalué la vitesse de changement de la qualité des sols par l’analyse de 23 parcelles d’une zone homogène converties progressivement en viticulture biologique depuis un maximum de 17 ans. Plusieurs indicateurs... |

| The rate of conversion of conventional vineyards into organic farming is currently increasing. This results in modifications of agricultural practices such as the application of organic manure, the use of tillage or grass-cutting to control weeds and the application of natural pesticides with preventive action. One of the aims of organic farming is to preserve the environment. In this context, the objective of our work was to evaluate the long-term effects of organic viticulture on soil quality. The study was conducted in a commercial vineyard where plots which had been organically managed for 7 (Organic7), 11 (Organic11) and 17 years (Organic17) were compared to conventionally managed plots (Conventional). Soil physical and chemical parameters (bulk... |

| Land management aiming to sustain ecosystem services is an important issue, especially in biodiversity hot spots such as found in Mediterranean areas. In Mediterranean areas, viticulture is an important land use. Vineyards are frequently found on inherently poor soils and are submitted to intensive management practices, which threaten soil functioning and associated ecosystem services. To encourage winegrowers and stakeholders to be reflective and adapt their vineyard practices, we evaluated the effects of three soil management practices (inter row plant cover duration, weeding and fertilization strategies) on soil functioning in 146 commercial plots distributed in Southern France, by a complementary set of biological and physico-chemical indicators. We... |

| Ce travail s’inscrit dans un projet de recherche visant à proposer aux viticulteurs un outil d’évaluation de la qualité de leurs sols, afin qu’ils puissent adopter des itinéraires culturaux plus respectueux de l’environnement. Dans le but d'accroître la trasnférabilité de cet outil, il est nécessaire de mieux connaître quelle(s) définition(s) les viticulteurs donnent de la qualité des sols et quels moyens ils utilisent pour l’évaluer. Pour répondre à ces questions, une enquête par entretien compréhensif a été réalisée auprès de 29 viticulteurs de 4 zones différentes du Languedoc-Roussillon (sud de la France). L’enquête a montré que les registres de la qualité des sols évoqués par les viticulteurs rappellent en de nombreux points les définitions proposées... |

| The rate of conversion from conventional vineyards to organic farming practices is increasing. Organic farming improves some soil properties, although some organic practices have negative effects on soils. The objective of this work was to study the long-term effects of organic farming through the use of soil nematodes as bioindicators of soil processes. Our experimentation was conducted in a commercial vineyard where plots belonged to two types of viticulture: conventional viticulture and organic viticulture (for 7, 11 and 17 years). The nematode community structure and nematode indices were determined. The main result was that organic practices increased soil nematode density. An increase in the available resources, as measured by a higher enrichment... |
