Short summary
(1) Solid state 13C-NMR is a powerful tool to study the nature of soil organic carbon. (2) Moderate mowing improved the stability of the grassland soil organic carbon pool. (3) Heavy mowing decreased the stability of the grassland soil organic carbon pool. (4) Mowing once a year is the most recommended practice in the semiarid grassland. (5) Mowing twice a year should be avoided for the long term in the semiarid grassland.
