Short summary
How can carbon be stored in red soils? Our 18-yr manure application reveals that applying manure stabilizes soil carbon through two key mechanisms: it helps soil particles clump together, physically shielding the carbon, and it improves soil conditions to promote minerals that act like glue, binding the carbon chemically. This research provides a sustainable strategy for enhancing soil fertility and mitigating climate change.
