چکیده انگلیسی
Contributions of organic matter and minerals in soil were evaluated by comparing changes in adsorption of methamidophos (MDP) and glyphosate (GPS) before and after removal of organic matter from argaltoll (mollisol) and typustalf (alfisol) soils. Adsorption isotherms of MDP and GPS by the two soils comforted to Freundlich equation, and the adsorption capacity of GPS by argaltoll soil was higher than that of MDP. Due to the removal of organic matter from soils, Kf values of MDP and GPS adsorbed by argaltoll soil, which were calculated from Freundlich equations and the measure of adsorption capacity, decreased by 46.1% and 75.0%, and these by typustalf soil decreased by 34.9% and 52.5%, respectively. Results from this study suggested that soil organic matter made greater contributions to adsorption of GPS, but soil minerals could provide more available adsorption sites for MDP.
