- ... Glyphosate (N-(phosphonomethyl) glycine) is one of the most widely used herbicides in the world. Experiments using distilled water or CaCl₂ extractor resulted in as much as 60% of glyphosate being desorbed from goethite. When Mehlich 1 extractor was used, desorption could reach up to 73%. At pHs 2.0, 4.0, 6.0, and 8.0, an increase in salt content decreased the adsorption of glyphosate onto goethit ...
