We complied the Global Soil Bulk Density DataBase (GSBDDB). This database inlcudes 162,470 soil samples (35,805 sampling sites) with bulk density (BD) and soil organic cabron (SOC) for the globle. Among them, 96,705 soil samples have soil particle size fractions (i.e. clay, silt and sand) as well. In addtion, this dataset also records spatial coordinates, elevation, mean annual precipitation, mean annual temperature, potential evapotranspiration and aridity index. This dataset is asscoated to the "Towards improved pedotransfer functions for estimating soil bulk density using the global soil bulk density database (DSBDDB)" by Chen et al. (in preparation).

Towards improved pedotransfer functions for estimating soil bulk density using the global soil bulk density database (DSBDDB). In preparation. When using the data, please cite repositories as well as the original manuscript. For any questions on the data, please contact Dr. Songchao Chen (chensongchao@zju.edu.cn).
