Data from a meta-analysis of the effects of biochar on hydrological properties of soils with different textures

The database was built by searching literature published on the Web of Science and Google Scholar. The search keywords included biochar and soil hydraulic property and/or soil physical property, and/or water retention, and/or field capacity, and/or wilting point, and/or plant-available water, and/or saturated hydraulic conductivity. A total of 104 articles were selected to form the database, categorize and assign appropriate levels to the collected data, considering both categorical and continuous variables。The data were used to assess the effects of biochar on the hydrological properties of soils with different textures by meta-analysis.

该数据库的构建基于对收录于《科学引文索引》和《谷歌学术》的文献进行检索。检索关键词包括生物炭、土壤水力特性及/或土壤物理特性、保水能力、田间持水量、凋萎点、植物有效水分及/或饱和水力传导率。共筛选出104篇文献以构建数据库，并对收集到的数据进行了分类和适当地赋予级别，同时考虑了分类变量和连续变量。数据被用于通过元分析评估生物炭对不同质地土壤水文特性的影响。
