LUZZI, Johana Ines et al. Degradation of atrazina in agricultural rotations on molisols in southwest chaqueño. Cienc. suelo [online]. 2021, vol.39, n.1, pp.183-189. ISSN 1850-2067.

SUMMARY

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.

Keywords : agricultural management herbicidal dissipation.
