DOIAbstract
Sorption and desorption efficiency of Chlorosulfuron that is sulfonylurea herbicide was checked by selecting different minerals and two types of Pakistani soils that were different on spatial scale. In Pakistan, sulfonylurea herbicide is being used against wide varieties of broad leaf weeds and for some grasses as well. Results obtained after the experimental work showed that adsorption co-efficient isotherm for Chlorosulfuron in tested soils data well fitted the Freundlich equation. In all the cases, slope n<1 was resembling the C type curve and isotherm was nonlinear. Due to low adsorption, distribution co-efficient (Kd) parameters were also low. Results indicated that soil samples (silt loam) collected from northern hilly areas Ayubia, K...
