ChSPD Chilean soil profile database V2

ChSPD is a soil profile database for Chile. The data was compiled from different published and unpublished sources. This new soil database covers a wide range of ecosystems and climate conditions. It comprises 20 different soil physical, hydraulic, and chemical properties. Each soil property has its own number of observations, which is determined by the soil horizons surveyed and the measurements taken at each point. The ChSPD_V2 includes 19769 georeferenced records, which represent 14029 soil profiles. The properties with the most records are organic matter (15797 data points), texture distribution (clay, sand, and silt content, 4978 data points), bulk density (5088 data points), field capacity (2020), and permanent wilting point (2012).ChSPD（智利土壤剖面数据库）是面向智利的土壤剖面数据库。该数据集整合了多类已发表与未发表的数据源。这款全新的土壤数据库覆盖了丰富多样的生态系统与气候条件，共涵盖20项不同的土壤物理、水文与化学属性。每项土壤属性的观测样本量，取决于所调研的土壤发生层（soil horizons）与各测点的实测数据规模。ChSPD_V2版本包含19769条带地理坐标的记录，共计14029个土壤剖面。观测记录数量最多的几项属性依次为：有机质（15797个数据点）、粒径分布（黏粒、砂粒与粉粒含量，共4978个数据点）、容重（5088个数据点）、田间持水量（2020个数据点）以及永久萎蔫点（2012个数据点）。
