Abstract : Soil erosion is recognized as one of the main processes of land degradation in agricultural environments. This study develops an original fingerprinting method to examine sediment source contributions in two contrasted agricultural catchments. Several properties were used to trace sediment lithological sources ⁸⁷Sr-⁸⁶Sr ratios, elemental concentrations, soil surface and subsurface sources ¹³⁷Cs and to quantify their temporal dynamics ⁷Be, ²¹⁰Pb xs.In the Louroux catchment 24 km², France, representative of drained areas of Northwestern Europe, results showed the dominant contribution of very fine particles
