Data underlying the publication: Assessment of the enhanced weathering potential of different silicate minerals to improve soil quality and sequester CO2

This data set contains the data collected from a down-flow soil column experiment studying the effects of enhanced weathering on soil quality and CO2 sequestration. The aim of the study was to quantify and compare the enhanced weathering potential, including effects on both soil quality and CO2 sequestration, of five different silicate minerals/rocks, namely olivine, basalt, wollastonite, anorthite, and albite. The soil column experiment was conducted for 64 days in a conditioned room. Soil columns contained 150 g of soil on which one of the silicate minerals was applied. Every two to four days, 40 mL de-mineralized water was added to the columns, after which leachate was collected and analysed. The data set contains one file with analyses conducted on the leachate during the experiment and one file with the analyses of the soils after the experiment. Further details can be found in the related paper published in Frontiers in Climate in 2023.

本数据集采集自一项探究增强风化（enhanced weathering）对土壤质量与二氧化碳封存（CO2 sequestration）影响的下渗土柱实验（down-flow soil column experiment）。本研究旨在定量对比五种硅酸盐矿物/岩石——橄榄石（olivine）、玄武岩（basalt）、硅灰石（wollastonite）、钙长石（anorthite）及钠长石（albite）——的增强风化潜力，及其对土壤质量与二氧化碳封存的综合影响。该土柱实验于可控环境室内开展，持续时长为64天。每个土柱装填150 g土壤，并施加上述某一种硅酸盐矿物。每2至4天向土柱中加入40 mL去离子水，随后收集渗滤液并开展分析检测。本数据集包含两份数据文件：其一为实验期间渗滤液的分析结果文件，其二为实验结束后土壤的分析结果文件。更多详细信息可参阅2023年发表于《气候前沿（Frontiers in Climate）》的相关研究论文。
