Abstract. The article presents the results of a comprehensive geoecological assessment of agricultural landscapes based on the analysis of spatially differentiated data from agrochemical and soil-physical surveys. А convergent approach was applied, combining methods of GIS analytics, geostatistics and data interpretation. The study was conducted from 2015 to 2025 in the steppe zone of the Orenburg Cis-Ural region. The geoecological stability of soils was evaluated using an Integrated Fertility Coefficient. Cluster analysis made it possible to identify and map four statistically significant (p < 0.05) typological groups of agricultural landscapes determined by the level and nature of anthropogenic pressure. Statistically significant inverse correlations have been established between the soil penetration index and the available soil moisture content (r = -0.87, p < 0.01), as well as a direct relationship with the number of ruderal plant species (r = +0.79). It has been revealed that in the conditions of the steppe zone of the Southern Urals, the physico-mechanical compaction of the soil is the dominant factor in reducing soil fertility and soil degradation. Based on the analysis of the Integrated Fertility Coefficient data, a geoecological zoning scheme of the territory with differentiated recommendations aimed at sustainable land management, has been developed.

Key words: geoecology, soil degradation, integrated soil fertility coefficient, anthropogenic pressure, soil compaction, sustainable land management, agricultural landscape.
