Aim of the study:
The study aims to assess soil quality in the Kharkiv Oblast using results from the 10th round of agrochemical surveys, and to develop and present geospatial data layers and thematic maps for monitoring changes in soil properties, in accordance with the requirements of the NSDI and the INSPIRE Directive.

Material and methods:
This article uses materials from the study of the results of the 10th round of agrochemical soil surveys of the Kharkiv Oblast, conducted and prepared in the format of a geospatial database by the State Institution “Soils Protection Institute of Ukraine.” Soil surveys, laboratory tests, classification of results, and visualization were performed in accordance with the approved methodology (Yatsuk and Baliuk, 2019). Cartographic and geospatial data for soil cover analysis were prepared and processed in a geographic information system (GIS) environment. All digital maps created in this study used the international coordinate system of WGS 84. All operations, including vectorization, spatial analysis, and the preparation of final layouts, were performed using QGIS (version 3.32.1).

Results and conclusions:
Using geoinformation technologies, an assessment of the qualitative (agrochemical and eco-toxicological) indicators of the soils of the region’s agricultural lands was conducted based on data from the 10th round of agrochemical studies. Thematic maps were constructed to reflect the spatial distribution of agrochemical parameters according to the approved gradations of agrochemical indicators, and the soil cover was characterized based on the results.
