Anthropogenic pollution triggers a series of processes that also affect the bioavailability of nutrients, the soil being a key element in food security and sustaining biodiversity. The purpose of this research is to identify the influence of the soil reaction and the values of the adsorptive complex indices (SH, SB, CEC, V) on the nutritional status of the soils around the town of Copșa Mică in the context of over 70 years of pollution). Soil pH is a reliable indicator of chemical transformations and a predictor of possible deficiencies or toxicity of elements necessary for plant physiology. The adsorptive complex indices have a diagnostic and prognostic role on the health of the soils, reflecting the degree of nutrient supply. In the 13 sample areas, the soil reaction varies from very strongly acidic to weakly alkaline, an important role being attributed to the influence of the orography of the land and the local pollutant-dispersing microclimate. The dynamics of the determined or calculated values of the adsorptive complex indices vary depending on the sampling depth and the investigated SP.
