Resumen:

ABSTRACT.- Integrated crop-pasture rotational systems can store larger soil organic carbon (SOC) stocks in the topsoil (0-20?cm) than continuous grain cropping. The aim of this study was to identify if the main determinant for this difference may be the avoidance of old C losses in integrated systems or the higher rate of new C incorporation associated with higher C input rates. We analyzed the temporal changes of 0?20?cm SOC stocks in two agricultural treatments of different intensity (continuous annual grain cropping and crop?pasture rotational system) in a 60-year experiment in Colonia, Uruguay. © Author(s) 2024.
