Mise en œuvre du Programme de Gestion Durable de l'Azote à l'échelle de deux petits bassins versants agricoles (Arquennes – Belgique) et évaluation d'impact par le suivi des flux de nitrate aux exutoires et par modélisation numérique

Application of the Sustainable Nitrogen Management Program in two small agricultural watersheds (Arquennes – Belgium) and impact evaluation by monitoring of nitrate fluxes at outlets and by numerical modeling. Four water catchments used by the Walloon Society of Water (SWDE) in the rural village of Arquennes (Province of Hainaut, Belgium) have been contaminated by nitrate (concentrations between 60 and 70 mg NO3-·l-1) for several years. The catchment basins (31 ha and 47 ha) are located exclusively in a cultivated area on loamy soils. Since October 2004, these basins have been used as a pilot... Mehr ...
