MECHANISMS OF INTERACTIONS AND THE SIGNIFICANCE OF DIFFERENT COLLOIDAL STRUCTURES IN THE VERTICAL TRANSPORT OF GLYPHOSATE IN SOILS WITH CONTRASTING MINERALOGIES.

Soil is regarded as a natural repository for strongly adsorbed pollutants since glyphosate (GLY) is preferentially adsorbed by the inorganic fraction of the soil, which may greatly limits its leaching. In this way, understanding how clay mineralogy influences the sorption and transport processes of glyphosate in soils with different mineralogical characteristics is highly relevant. In this work, two clay mineralogy contrasting soils were used to evaluate GLY retention: a Oxisol (OX) with high levels of iron oxides (amorphous and crystalline) and a Inceptisol (IN) with a predominance of kaolinite.
