Résumé : Applications of so-called organic wastes are recommended in agriculture where the organic matter content of soil is low. However, before applying organic wastes to soil it is essential to assess that these materials do not pose any hazard to humans, animals, or to the environment. This study aims at evaluating the dynamic of trace elements in a soil amended with various organic wastes combining incubation and DGT techniques. Soil/waste samples were incubated to evaluate the impact of organic waste application on trace elements exchangeable fractions by exploring the DGT response. Organic wastes were incorporated at 80 t ha-1 of dry matter. During organic waste mineralization, we have detected increase in the exchangeable fractions of trace elements, which was more noticeable for Zn and Pb than for Cu, Cd, Ni and Cr.
