Modelling herbicide treatment impact on groundwater quality in a central Italy area

Abstract: -A simulation study, using the MACRO-DB pesticide leaching model, was carried out to determine the impact of different weed control strategies on groundwater quality in a Central Italy area (Umbria) where the drinking water wells for the city of Perugia are located. The simulations considered nine representative soil profiles and two different crop rotations. Weather conditions were those of ten years. Thirty herbicides and twenty-two weed control strategies were tested for their groundwater concentrations. Tw… Show more

“…These include limitations to the crops to which a compound can be applied, the timing/crop stage at which application may be made to each specific crop, application rate, number of applications, and the interval between applications (6). Businelli et al (7) suggest that risk of groundwater pollution may be mitigated by a carefully designed crop rotation: crop rotation changes the interval between applications and manages pest populations by breaking the developmental cycle of pests (8). For these reasons, crop rotation should be considered as a mitigation technique.…”
