Abstract

The atrazine molecule in the soil is degraded by chemical and microbiological processes,
depending on the physicochemical, biological properties of the substance and on
meteorological factors such as temperature and humidity. The objective was to evaluate
the time of degradation and the presence of metabolites in contrasting agricultural
managements during a period after application. The work was carried out in a field trial
and we could see that in a period less than 30 days the concentration of atrazine was
reduced by 90% in the first 5 cm of depth.
