Characterization of the heavy, hydrolysable and non-hydrolysable fractions of soil organic carbon in conventional and no-tillage soils
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.
