摘要: The leaching of diuron and oryzalin through undisturbed soil columns was studied in the laboratory using three vineyard soils from Vosne-Romanee (Burgundy): a rendosol, calcosol vegetated calcosol. After 845 mm simulated rainfall 15 days, leachates contained higher amounts (3.2%, 11.8% 18.8% applied diuron, respectively) than (0.2%, 4.9%, 3.7%, respectively). A greater proportion extractable residues obtained for (42.5%, 26.8% 32.2%, (14.7%, 12% 15.5%, mobility might be related to its water solubility (36.4 mgl(-1) compared with 2.6 oryzalin) smaller adsorption coefficient (400 lkg(-1), 700-1100 lkg(-1) oryzalin). two herbicides calcosols not only due different organic carbon contents but also textures structures.
