Abstract
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.
期刊介绍：
Environmental Chemistry Letters explores the intersections of geology, chemistry, physics, and biology. Published articles are of paramount importance to the examination of both natural and engineered environments. The journal features original and review articles of exceptional significance, encompassing topics such as the characterization of natural and impacted environments, the behavior, prevention, treatment, and control of mineral, organic, and radioactive pollutants. It also delves into interfacial studies involving diverse media like soil, sediment, water, air, organisms, and food. Additionally, the journal covers green chemistry, environmentally friendly synthetic pathways, alternative fuels, ecotoxicology, risk assessment, environmental processes and modeling, environmental technologies, remediation and control, and environmental analytical chemistry using biomolecular tools and tracers.
