Short summary
Short summary
Through the analysis and modeling of SOC and isotope (Δ14C and δ13C) data from contrasting treatments in a 60-year agricultural experiment, we found that mineral-associated SOC is highly isolated from recent atmospheric CO₂ inputs, with isolation increasing with soil depth. Integrated crop-pasture rotational systems have not been able to sequester substantial new carbon along the profile, particularly at depth, but they are relevant to preserve the natural carbon legacy of these soils.

Short summary
Short summary
Based on an approach that involved soil organic carbon (SOC) monitoring, radiocarbon measurement in bulk soil, and incubations from a long-term 60-year experiment, it was concluded that the avoidance of old carbon losses in the integrated crop–pasture systems is the main reason that explains their greater carbon storage capacities compared to continuous cropping. A better understanding of these processes is essential for making agronomic decisions to increase the carbon sequestration capacity.

Back to the future? Conservative grassland management can preserve soil health in the changing landscapes of Uruguay(Säumel et al., 2023; https://doi.org/10.5194/soil-9-425-2023). We identified several design and methodological problems in the aforementioned publication that may induce potential misinterpretations.
