Summary
This field-scale investigation characterised the natural variability of stable isotope signatures and elemental composition in agricultural soils to inform sediment fingerprinting and tracing methodologies. The work suggests—as indicated by the title—that understanding temporal and spatial heterogeneity in these properties is essential for reliable sediment source apportionment in agricultural landscapes. The findings have implications for the design and interpretation of sediment tracing studies used to attribute erosion to specific field management practices.
UK applicability
Given the UK authorship and Geoderma journal context, the findings are likely directly applicable to UK farming systems and soil monitoring. The variability thresholds reported would inform soil sampling strategies for sediment source tracing in UK agricultural catchments and support evidence-based erosion control policies.
Key measures
δ13C, δ15N, total carbon (TC), total nitrogen (TN), spatial and temporal variation in soil properties
Outcomes reported
The study examined spatial and temporal variability of carbon and nitrogen stable isotope ratios (δ13C, δ15N) and total carbon and nitrogen content (TC, TN) across a field scale to assess their utility as tracers for sediment source identification.
