Global Soil Bulk Density DataBase (GSBDDB)

<p>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.&nbsp; 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,&nbsp;elevation, mean annual precipitation, mean annual temperature, potential evapotranspiration and aridity index.</p> <p>This dataset is asscoated to the&nbsp;&quot;Towards improved pedotransfer functions for estimating soil bulk density using the global soil bulk density database (DSBDDB)&quot; by Chen et al. (in preparation).</p> <p>Manuscript citation: Chen, S., Dai, L, Shuai Q., Xue, J., Zhang, X., Xiao, Y., et al.&nbsp;Towards improved pedotransfer functions for estimating soil bulk density using the global soil bulk density database (DSBDDB). In preparation.</p> <p>When using the data, please cite repositories as well as the original manuscript.</p> <p>For any questions on the data, please contact Dr. Songchao Chen (chensongchao@zju.edu.cn).</p>
