Résumé

leaching. Finally, a sensitivity test was performed to evaluate the more sensitive
parameters regarding the remaining mass of pesticide in soil and leaching.
The findings of the study show that the dynamic of the remaining mass of
pesticide in soil is a relevant issue to understand pesticide dissipation at long
term. Attention must be paid on parameters influencing sorption and availability
of the pesticide for leaching.
To conclude, the significant discrepancies in the simulated pesticide leaching for
the two types of crops (maize and wheat) highlight the interest of using a crop
model to simulate the fate of pesticides at the catchment scale.
