摘要：A critical aspect of predicting soil organic carbon (SOC) concentrations is the lack of available soilinformation; where information on soil characteristics is available, it is usually focused on regions of high agri-cultural interest. To date, in Chile, a large proportion of the SOC data have been collected in areas of intensiveagricultural or forestry use; however, vast areas beyond these forms of land use have few or no soil data available.Here we present a new SOC database for the country, which is the result of an unprecedented national effortunder the framework of the Global Soil Partnership. This partnership has helped build the largest database ofSOC to date in Chile, named the Chilean Soil Organic Carbon database (CHLSOC), comprising 13612 datapoints compiled from numerous sources, including unpublished and difficult-to-access data. The database willallow users to fill spatial gaps where no SOC estimates were publicly available previously. Presented values ofSOC range from 6×10 −5 % to 83.3%, reflecting the variety of ecosystems that exist in Chile.ThedatabasehasthepotentialtoinformandtestcurrentmodelsthatpredictSOCstocksanddynamicsatlargerspatial scales, thus enabling benefits from the richness of geochemical, topographic and climatic variability inChile.The database is freely available to registered users at https://doi.org/10.17605/OSF.IO/NMYS3 (Pfeiffer et al.,2019b) under the Creative Commons Attribution 4.0 International Public License.
