The determination of changes in soil organic carbon (SOC) content under different cropping systems is necessary for policy development oriented towards soil conservation, C sequestration, and future C credit markets. The aim of this study was to generate an open SOC dataset resulting from a systematic literature search related to the agricultural systems for Southeast Asia. The dataset has 209 articles and 4341 observations on soils of cropping systems in this region from articles published between 1987 and 2023. This dataset included different management practices, land uses, soil sampling depth, and length of SOC content assessment. In addition, inherent features of crop production reported in the experiments were included in the dataset. This dataset can be applied to quantify and compare the impact of different land uses or management practices on SOC content, providing foundational knowledge towards identifying sustainable practices. Lastly, it is a useful guide for future regional SOC sequestration policies and the development of C credit markets.

确定不同耕作制度下土壤有机碳（SOC）含量的变化对于制定面向土壤保持、碳封存和未来碳信贷市场的政策是必要的。本研究的目的是通过与东南亚农业系统相关的系统文献检索来生成开放的 SOC 数据集。该数据集包含 1987 年至 2023 年间发表的文章中关于该地区耕作系统土壤的 209 篇文章和 4341 个观察结果。该数据集包括不同的管理实践、土地利用、土壤采样深度和 SOC 含量评估的长度。此外，实验中报告的作物生产的固有特征也包含在数据集中。该数据集可用于量化和比较不同土地利用或管理实践对 SOC 内容的影响，为识别可持续实践提供基础知识。最后，它对未来区域性SOC封存政策和C信贷市场的发展具有有益的指导作用。
