The aim of this study was to determine nutrient elements in soybean (Glycine max) plants cultivated in farm soil amended with nCeO₂ at 0–1000 mg kg⁻¹ and nZnO at 0–500 mg kg⁻¹. Digested samples were analyzed by ICP-OES/MS. Compared to control, pods from nCeO₂ at 1000 mg kg⁻¹ had significantly less Ca but more P and Cu, while pods from 100 mg kg⁻¹ nZnO had more Zn, Mn, and Cu. Plants treated with nZnO showed significant correlations among Zn, P, and S in pods with Zn in roots. Correlations among pod Zn/root Zn was r = 0.808 (p ≤ 0.01) and pod P/root P was r = 0.541 (p ≤ 0.05). The correlation among pod S/root S was r = −0.65 (p ≤ 0.01). While nCeO₂ treatments exhibited significant correlations between pod Ca/root Ca (r = 0.645, p ≤ 0.05). The data suggest that nCeO₂ and nZnO alter the nutritional value of soybean, which could affect the health of plants, humans, and animals.
