Reference soil samples (pH, soil texture, SOC, TC, TN, P, K, Mg) from the project "pH-BB: Precision liming in Brandenburg" - data set 2 (farm 2)

Within the EIP-AGRI-funded project “pH-BB: Precision liming in Brandenburg”, research was conducted on improving the management of soil acidity on farms in the federal state of Brandenburg (Germany). With the help of mobile proximal soil sensors, the lime-relevant soil parameters pH value, texture and soil organic matter were recorded time-saving, cost-effectively and on a small scale. Regulations for processing the sensor data and deriving fertilization recommendations were developed. An important sub-step in determining the lime requirement is the site-specific calibration of the sensor data in order to obtain high-resolution maps of the lime-relevant soil parameters. For this purpose, soil samples were taken from all mapped plots and analyzed for pH, soil organic carbon and grain size distribution. The analyzed results of the first out of three participating farms in the project are available in this data set. Furthermore, in addition to the analysis of the pH value, a basic soil investigation was carried out determining the plant-availability of phosphorus, potassium and magnesium. To date, the dataset consists of a total of 599 entries for pH, 508 for soil organic carbon, total carbon and total nitrogen content, 581 for P, K and Mg, and 374 for soil texture (clay, fine silt, medium silt, coarse silt, fine sand, medium sand, coarse sand). For each measurement point, both the coordinates in UTM format (EPSG 25833) and the measurement date were recorded. This table contains the index of all tables forming this data collection.
