The use of environmental radionuclides in soil monitoring has made it possible to establish erosion rates. combined 137Cs and 210Pbex is a common approach for determining mean annual rates retrospectively two different time windows; the past 50–60 years whereas provide longer period up 100 years. However, these have contrasting sensitive behaviors, able be more recent redistribution events its last disintegration (22.3 yr) than 137Cs, being depositional events.

<p>Recent agriculture expansion and land cover conversion (post-1985) induced major deleterious environmental effects in South-America general Uruguay particular, affecting locally the sustainability of soil water resources. Whilst consequences agriculture’s development were largely studied (e.g. monitoring, modeling) Europe or North America, much less attention was devoted to intensity degradation more specifically, on Pampa Biome. In this study, sediment cores...
<p>The study site consists of two sub-basins (“Arbolito”, 20.94 km2; and “Horno”, 10.44 km2) divided by the Rolon stream, which in turn flows into Baygorria hydroelectric dam reservoir (-32.77152 S; -56.84093 W). The "Arbolito" sub-basin natural pasture with extensive cattle from 19th century to present day.  Soils are predominantly eutric brunosols clayey haplic vertisols slopes > 6%...
