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.
