Processus de transfert superficiel des produits phytosanitaires, de la parcelle au bassin versant

Superficial transfer process of pesticides, from the plot of land to the catchment area

Cemagref, Lyon

Abstract

Runoff and diverse other forms of low depth flow generate transfers towards catchment areas of subtances which are partly due to agriculture practices: nitrogen, phosphorus, pesticides, suspended matter. They are at the origin of pollution in surface water. Numerous factors determine the future and the transfer attenuation from the source to the rivers of these products. The quantification of the processes is still a problem and is a theme of research.
