Glyphosate retention in grassland riparian areas is reduced by the invasion of exotic trees

The study found that treeless riparian vegetation strips in the Argentinean Pampas are more effective at retaining glyphosate, reaching nearly 74%, compared to areas invaded by willow trees. While willow trees reduced runoff by 63% and altered soil moisture and biomass, they did not significantly change sediment retention compared to grassy controls. Glyphosate retention was positively correlated with sediment retention but negatively correlated with riparian slope and litter biomass.

• Riparian vegetation strips without trees exhibited higher glyphosate retention, reaching nearly 74%, compared to areas invaded by willow trees.
• The presence of willow trees resulted in a 63% reduction in runoff and significantly altered biophysical properties, including aboveground biomass and soil moisture, although sediment retention did not differ significantly from grassy controls.
• Glyphosate retention is positively influenced by sediment retention, while it is negatively influenced by litter biomass and the riparian slope.
