Abstract:
CAROB is a community project that uses a collaborative and open-source approach to standardize and compile open agricultural research data from experiments and surveys. The goal is to facilitate the further use of these data in research and development. The project compiled agricultural research data into groups with similar variables. This resource ("soil_samples") combines 10 standardized individual data sources, aggregating several soil biological, chemical, and physical parameters from 76 countries into a comprehensive dataset.
During the data cleaning process, the SoilHive team dropped some points that either didn’t have information for the soil properties we retain or fell on water. Additionally, some records in the dataset have low-precision coordinates. Users are advised to consider this limitation when working with the data and consult the FAQ for further details. The full dataset, comprehensive of data beyond the soil domain, can be found at carob-data.org.
