Can biochar amendment alter the sorption of glyphosate in the Australian Vertosol soil system?

Biochar has the potential to adsorb glyphosate, a potential groundwater pollutant in areas having indiscriminate use in farming activities. Batch sorption experiments were conducted at the University of Sydney, Australia. 14C radiolabeled glyphosate was used to study the behaviour of glyphosate in Vertosol soil systems using the liquid scintillation counting method. Radiotracer data showed no effect of char application on the adsorption behaviour of glyphosate in Vertosols due to the presence of clay.
