This study provides an integrated analysis of the pedological characteristics of soils in the Geoagiu area (Hunedoara County, Romania), with a focus on soil types, physico-chemical properties, limiting factors, and their land use implications. The study area is characterized by a high diversity of pedogenetic conditions, resulting from the interaction of major geomorphological units and the variability of lithological substrate, climate, and hydrological regime. The results highlight the predominance of Cambisols (approximately 79%), followed by Luvisols and other soil types occurring in smaller proportions. Cambisols exhibit favorable properties, including high humus content and well-developed structure, being associated with moderate to high fertility. In contrast, Luvisols are characterized by clay accumulation in subsurface horizons, leading to hydrophysical constraints, while Dystric Cambisols are affected by high acidity and low nutrient status. The main limiting factors identified include soil acidity, high skeletal content, clay-rich texture, erosion, and the influence of altitude on climatic conditions. The analysis of pedological relationships reveals direct links between parent material, soil properties, and vegetation types, confirming the key role of lithological substrate and climatic conditions in soil formation and evolution. The findings emphasize the importance of site-specific land use according to soil properties and limitations, as well as the need for sustainable management practices aimed at maintaining soil fertility and preventing soil degradation in the studied area.
