Assessment of the potential risk of leaching pesticides in agricultural soils: study case Tibasosa, Boyac=a, Colombia

Agricultural soils need monitoring systems to address pesticide risks for humans and the environment. The purpose of this paper was to obtain leaching risk maps of the pesticides imidacloprid, lambda-cyhalothrin, and chlorpyrifos in agricultural soil under an onion (Allium cepa L.) crop in Tibasosa, Boyac = a, Colombia. This was obtained by studying the soil types in the area, analyzing the behavior of pollutants in the soil profile, using a delay factor and an attenuation factor to finally include GIS allowing visualization of the areas of greater potential risk in the study area.

Automated summary

This study aims to obtain leaching risk maps of pesticides under an onion crop in Tibasosa, Boyacá, Colombia by studying soil types, analyzing pollutant behavior, and utilizing GIS technology for visualizing areas of greater potential risk.
