Estimating the amount of pesticides applied on watersheds. Pesticide input parameters are required for using the main models which have been proposed to describe the fate of pesticides. We suggest a method to evaluate the input of agrochemicals on an agricultural watershed. First, land use was estimated using aerial photographs, fields observations, and data from the French National Agricultural Census (RGA). Second, the input of agrochemicals on each cropping was estimated, since 1970, from a survey at the farm level. These data were confirmed by local marketing technicians. Finally, the total quantity of agrochemicals was computed as the product of the input of agrochemicals on each cropping and the surface area of each type of land use. ...
