Glyphosate adsorption in a soil depth profile

Glyphosate [N-(phosphonomethyl)glycine, PMG] is the most popular, non-selective, post-emergent and widely used herbicide in agriculture, especially in soybean crops. The Ap (0-18 cm), AB (18-50 cm) and BC (105-130 cm) horizons of a Typic Haplustoll soil, located at 62°06'W, 27°24'S, in Pro...
