Abstract:
L’élimination des produits agrochimiques indésirables des eaux de drainage agricole dans les bassins versants peut être réalisée par des zones humides ouvragées. Les oxy-hydroxydes de fer sont parmi les composés les plus réactifs chimiquement dans les sols tempérés et pourraient être un support idéal en mélange avec un support traditionnel pour la végétation dans ces systèmes. Le présent mémoire expose un travail de recherche visant à tester l’efficacité d’un procédé novateur d’élimination du glyphosate par un filtre minéral planté qui utilise les propriétés d’un support de grande surface spéc

Abstract:
Dans le département de l'Eure, l'utilisation de la ressource souterraine pour l'alimentation en eau est contrariée par différents types de pollution ; les nitrates, les matières en suspension, les contaminations bactériennes, les produits phytosanitaires pour l'essentiel. La nature karstique du sous-sol favorise l'écoulement rapide des eaux de surface non épurées vers l'aquifère. L'évolution de ces vingt dernières années a vu une intensification des pratiques culturales, même si celle-ci est maintenant suivie d'une limitation des volumes de production. Le drainage constituait alors un outil de

Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgico<br>Salt excess in the soil solution is a serious problem in agriculture, caused mainly by irrigation water, causing soil salinization. These salts, when absorbed affects the growth of plants because of the osmotic effect, reducing the absorption of water in the soil. In order to mitigate the deleterious effects of these salts in plants, several strategies have been developed in order to make plants most tolerant to salt stress.
