Controlling phosphorous (P) inputs through management of its sources and transport is critical for limiting freshwater eutrophication. In this study, characteristics of exogenous rare earth elements (REEs) and P and their losses with surface runoff (both in the water and sediments) during simulated rainfall experiments (83 mm h−1) were investigated. The results revealed that on average most REEs (La, 94%; Nd, 93%; Sm, 96%) and P (96%) transported with sediments in the runoff. The total amounts of losses of REEs and P in the runoff were significantly correlated, suggesting the possibility of using REEs to trace the fate of agricultural nonpoint P losses.
► It is a explorative research of using REE as a tracer to track nonpoint P loss. ► The results revealed that most REEs and P transported with sediments in the runoff. ► REEs and P in the runoff were significantly correlated. ► Results suggesting the possibility of using REEs to trace the fate of P losses.
