“…The transport of Br − in these columns was previously described in Okada et al (2014). The authors found that the Br − breakthrough curves (BTC) exhibited an asymmetric behavior and tailing, indicating the occurrence of preferential flow.…”

“…Inside the chamber, a fraction collector was used to collect the effluent at different time intervals. Previous to the glyphosate injection, bromide (Br − ) was used as a tracer to characterize nonreactive solute movement in the studied columns (Okada et al, 2014). After all the Br − was leached (approximately 3 PV), a pulse of a commercial solution of glyphosate (ATANOR II®) equivalent to 6 L ha was applied for 15 min (volume of injection: 6 ml; pulse concentration: 199 mg L −1 of active ingredient dissolved in a 0.01 M CaCl 2 solution).…”

“…Ochsner et al (2006) reportaron que la accesibilidad a los sitios de adsorción pareciera estar influenciada por el contenido hídrico del suelo, especialmente en texturas arcillo limosas y francas, en comparación con suelos limosos. Okada et al (2014) analizaron el impacto a largo plazo de la SD y la LC en el transporte de solutos en tres tipos de suelos distintos de la Región Pampeana Argentina. Estos autores encontraron que en los suelos con alto contenido de arcilla, la dispersión de soluto, obtenida a partir de ensayos de desplazamiento miscible hechos con bromuro de potasio como soluto, fue mayor en SD.…”
