- •
Grain for Green Project initiated in 1999 converts cropland to grassland/shrubland.
- •
Impact of Grain for Green on carbon cycling on Qinghai–Tibetan Plateau is unknown.
- •
Effects on carbon partitioning and turnover were accessed by 13CO2 pulse labeling.
- •
Different mass of 13C in excess, similar 13C partitioning are shown in grasslands.
- •
Soil organic carbon of cropland will be restored to natural grassland over 100 yr.
