This dataset contains open-access soil nutrient maps for the Region of Murcia, Spain, produced by Siora. It provides high-resolution (30 m) spatial data for five key soil variables: Nitrogen (N), Phosphorus (P), Potassium (K), Organic Carbon (OC), and pH. Three time steps are included: 2000, 2010, and 2020, allowing comparisons of soil fertility changes across two decades.
Each package includes:
- GeoTIFF raster files with nutrient concentrations (mg/kg)
- Preview PNGs for quick visualization
- Metadata JSON with technical specifications
- A README with methodology notes
- CC-BY 4.0 license
These maps are derived from satellite reflectance spectroscopy combined with auxiliary variables such as terrain and climate, calibrated against reference laboratory methods (ISO and USDA standards).
The dataset is intended for use in agronomic research, precision agriculture trials, environmental monitoring, and geospatial modeling.
