摘要：
The adsorption of metsulfuron methyl to tropical agricultural soils were found to best fit a Freundlich adsorption isotherm with distribution coefficients (Kd) ranging from 0.45-46.23. A positive correlation between organic matter content and adsorption was observed, while a significant negative correlation was seen between soil pH and adsorption. The extent of desorption of metsulfuron methyl was also observed to decrease with increasing organic matter content of the soil.
