Quantification of types of soil organic carbon (SOC) under different tillage systems is important in understanding SOC dynamics and storage. Tillage influenced the stable heavy fraction of SOC, which comprises 90–93% of total SOC. But the impact of tillage on the heavy fraction and its components was only seen in the 0–10 cm soil depth. Newly-derived carbon in the heavy fraction was preserved under no-tillage, but there was no difference in carbon sequestration potential looking at the 0–30 cm depth in the short-term.
Not all soil organic matter is the same, and soil management practices may impact types of organic matter differently. This

This study set out to evaluate crop rotation diversity, perenniality, carbon inputs, and carbon input quality as predictors of soil organic carbon concentration and aggregate
