Abstract In China, the Grain for Green Program (GGP) is an ambitious project to convert croplands into natural vegetation, but exactly how changes in vegetation translate soil organic carbon remains less clear. Here we conducted a meta‐analysis using 734 observations explore effects of land recovery on and nutrients four provinces Southwest China. Following GGP, content (SOCc) stock (SOCs) increased by 33.73% 22.39%, respectively, compared with surrounding croplands. Similarly, nitrogen increased, while phosphorus decreased. Outcomes were heterogeneous, depended variations environmental characteristics. Both regional use cover change indicated landscape type transfer matrix net primary production from 2000 2020 further confirmed that GGP promoted forest area mean production. Our findings suggest could enhance sequestration China help develop carbon‐neutral strategy.
