Assessment of Soil Erosion Over Six Decades in a Long‐Term Experiment Using Fallout 137Cs and RUSLE: A South American Case Study

Land Degradation &Development, EarlyView.
ABSTRACT Soil erosion remains a major global concern affecting agricultural productivity and land sustainability. This study investigates the magnitude and variability of soil erosion in a long‐term experiment (LTE) established in 1963 in Colonia, Uruguay, aiming to compare the performance of the 137Cs tracer technique and the RUSLE model across ...
