Short summary
This study explores heterogeneity in 14C content of soil organic matter (SOM) at different spatial scales and across climatic and geologic gradients, which is essential for a better understanding of SOM stability. Results reveal that despite dissimilar environmental conditions, 14C contents in topsoils is relatively uniform and 14C trends with depth are similar. Plot-scale variability is significant. Statistical analysis found a significant correlation of 14C contents (0–5 cm) and temperature.
