The dataset of biochar effects on soil hydrology and crop water use efficiency

The published studies used for database construction until September 2020 were collected from Web of Science and China National Knowledge Infrastructure (CNKI), using the keywords ‘biochar’ or ‘charcoal’, ‘soil’ and ‘yield’ or ‘soil porosity’ or ‘available water content’ or ‘field water capacity’ or ‘water use efficiency’ for literature retrieval. The period of literature search for database building was from 2010 to 2020.Abbreviations: WUE, water use efficiency; AWC, available water content; SSHC, soil saturated hydraulic conductivity; WC, soil water content; SP, soil porosity; BD, soil bulk density; SOC, soil organic carbon ; FWC, field water capacity; PWP, permanent wilting point ; CP, capillary porosity; SMC, saturated moisture content; MWD, mean weight diameter.
