This study presents a spatial assessment of agro-landscape soil contamination by phosphorite plant emissions under semi-arid conditions in the vicinity of Taraz, Kazakhstan. A total of 120 soil samples (0–20 cm) were collected from eight wind-oriented directions (N, S, W, E, NW, NE, SE, SW) at distances of 1, 2, 5, 10, and 20 km from the emission source. The chemical analysis included total and available forms of Zn, Cu, Cd, and Pb, while soil texture was classified based on granularity. Concentrations of total Zn exceeded the maximum permissible concentration (MPC: 100 mg/kg) in 12.5% of the samples, with the highest values observed along the northern and north-eastern transects. Available Cu also surpassed its MPC (3 mg/kg) in several sites located to the north and northwest of the plant. Pearson correlation analysis revealed a strong negative relationship between metal concentrations and distance from the pollution source, particularly for Zn (r = –0.82), Cu (r = –0.65), and Pb (r = –0.59). Additionally, a significant correlation was observed between total Cd and soil texture (r = 0.88 with granularity), highlighting the role of fine particles in metal retention. Principal Component Analysis (PCA) indicated that the first two components (PC1 = 33.1%, PC2 = 18.7%) accounted for over 50% of the variance. PC1 was driven by total and available forms of Zn and Cu, while PC2 was associated with Pb and soil texture. PCA biplot results clearly separated the northern and north-eastern directions from other sectors, corroborating the dominant wind directions identified from meteorological data (southerly and south-easterly flows). This anisotropic pattern of metal deposition suggests a prevailing wind-driven dispersion of contaminants from the phosphorite plant. The findings underscore the necessity of integrating wind-directional considerations into regional soil monitoring frameworks and provide a scientific basis for future environmental risk assessment and remediation planning in industrialized semi-arid zones.
