Dissolved Organic Matter and Adsorption-Desorption of Dimefuron, Atrazine, and Carbetamide by Soils

Dissolved organic matter (DOM) from several sources influenced the absorption and the desorption by soil of there herbicides: dimefuron {4-[2-chloro-4-(3,3-dimethyluyreido) phenyl]-2-t-butyl-1,3,4-oxadiazolin-5-one}, atrazine (2-chloro-4-ethylamino-6-isopropyl-amino-s-triazine), and carbetamine [D-N-ethyl-2-(phenyl-carbamoyloxy)propioamide)]
