Supplementary information files to 'Synergistic effects of multiple "good agricultural practices" for promoting organic carbon in soils: A systematic review of long-term experiments.' by López i Losada et al.

This upload contains the supplementary information files for the systematic review and meta-analysis of time series data of Soil Organic Carbon (SOC) measurements in long-term field experiments performed in 'Synergistic effects of multiple “good agricultural practices” for promoting organic carbon in soils: A systematic review of long-term experiments.' by López i Losada et al. 2025 The protocol for the systematic review can be found in 'Which agricultural management interventions are most influential on soil organic carbon (using time series data)?' by Haddawat et al. 2016 [DOI: 10.1186/s13750-016-0053-z] R scripts used to calculate net SOC change rates from individual time series (regressions.R) and effect sizes from management interventions (metanalysis.R) are provided along with auxiliary files (time_labs.xlsx, statistics.xlsx, and SOCdata.xlsx). Supplementary files S1, S2, and S4 provide an overview of the systematic review method and its findings. Supplementary file S1 is also an auxiliary file to run the R scripts. Supplementary files S3 and S6 contain the output summary of statistics from the analysis performed in the R scripts. This project was financed by the Mistra Council for Evidence-Based Environmental Management (EviEM), FORMAS Grant 2018-01726 (to Y. Clough) and the strategic research area Biodiversity and Ecosystems in a Changing Climate (BECC).本上传文件包含López i Losada等人2025年发表的《多项“优良农业实践”协同促进土壤有机碳累积——长期田间试验系统综述》中，针对长期田间试验土壤有机碳（Soil Organic Carbon, SOC）实测时间序列数据开展的系统综述与元分析的补充信息文件。本系统综述的研究方案可参阅Haddawat等人2016年发表的《哪些农业管理干预措施对土壤有机碳影响最为显著？（基于时间序列数据）》[DOI: 10.1186/s13750-016-0053-z]。本数据集附带了用于从单条时间序列计算SOC净变化率的R脚本（regressions.R）、用于计算农业管理干预措施效应量的R脚本（metanalysis.R），以及辅助文件time_labs.xlsx、statistics.xlsx与SOCdata.xlsx。补充文件S1、S2与S4概述了本系统综述的研究方法与主要研究结果。其中补充文件S1同时可作为运行上述R脚本的辅助文件。补充文件S3与S6包含了通过R脚本开展分析后得到的统计结果汇总。本项目由循证环境管理委员会（Mistra Council for Evidence-Based Environmental Management, EviEM）、FORMAS项目资助编号2018-01726（授予Y. Clough）以及气候变化下生物多样性与生态系统战略研究领域（BECC）资助完成。
