摘要：

Soil carbon sequestration is a climate engineering process that could significantly reduce global warming, yet actual estimates of soil organic carbon sequestration in China's croplands are probably underestimated. Here we estimated soil organic carbon sequestration across China's croplands from 1980 to 2018 using four different methods. We found that the average sequestration rate in China's croplands is 298.5 kg ha-1. We present management strategies that could increase the mean soil organic carbon stock by 58.2 Mg ha-1. Insights into the potential for region-specific strategies to enhance soil carbon sequestration are given.
