Evaluation des contraintes engendrées par les engins dans les systèmes de grandes cultures, viticoles et forestiers français

Abstract : Soil compaction is a major process of soil physical degradation in EU. Soil compaction occurs when soil is subject to mechanical constraints through the use of heavy machinery in agriculture and Forestry. The French ministry of Ecology and sustainable development support a project DST on “Soil physical degradation by compaction”. The aim is to improve knowledge on compaction problems in France. A first work was to evaluate stress which is applied on the ground and the conditions in which they are applied for cropping, vineyard and forest system. First we determined the best way to calculate soil constraints from bibliography and some experiments. Especially the work was focused on the prediction of the contact area between tyre and soil from easily accessible parameters. The second step consisted in meeting the experts of each production, in order to make profit of their knowledge and expertise. From this inventory, we calculated the constraints by system and locating them on a chart of France. With regard to sugar beat production, we put into evidence the effort made by French farmers to limit soil compaction at seedbed preparation. In contrast sugar beat harvesting induces high constraints about 150kPa. Similar constraints at harvesting were found for vineyard and forestry systems.
