Valorisation de la Carte Numérique des Sols de Wallonie et d'une base de données disponible en analyse de sols, dans le cadre de l'évaluation du risque de pollution des eaux souterraines par les pesticides

Making use of the Digital Soil Map of Wallonia and of an available soil analysis database for assessing the risk of pesticide leaching to groundwater. This study shows how the Digital Soil Map of Wallonia and the associated soil database Aardewerk can be combined with the MetaPEARL model to assess the sensitivity of agricultural soils to pesticide transfer into underground water tables in Wallonia (Southern Belgium). MetaPEARL is based on an analytical expression which describes the concentration of leached pesticides at the soil profile bottom depending on available data on soil characteristi... Mehr ...
