2026-08-31 Integration of Selected Soil Monitoring Parameters and Remote Sensing Data in the Black Soil Study Area doi:10.57760/sciencedb.iga.001dz en This dataset comprises image files, tabular data files, and remote sensing imagery. The image files consist of landscape photographs captured in July 2022 during field sampling in the Sanjiang Plain of Heilongjiang Province, stored in JPG format, with a total of 20 images and a data volume of 64.3 MB. The tabular data file, in XLSX format, contains laboratory-measured soil organic matter data and visible–near-infrared spectral reflectance measurements (wavelength range 400–2450 nm), with a data volume of 575 KB. The remote sensing imagery consists of Sentinel-2 surface reflectance images (Level-2A) covering the Youyi Farm in the Sanjiang Plain, spanning April to June of each year from 2019 to 2023; after median compositing, three annual GeoTIFF files were generated, with a total data volume of 12.2 GB. This dataset covers the main cultivated areas of Youyi Farm and supports inter-annual variability analysis. Its applicable fields include remote sensing-based retrieval of soil properties, cultivated land quality assessment, and monitoring of black soil protection policy effectiveness.
