Selenium (Se) is an essential micronutrient that often deficient in human and animal diets. As primary dietary components, cereals, legumes, vegetables present viable targets for Se biofortification. However, systematic comparisons of behavior the soil environment across diverse crops remain limited. To address this, incubation pot experiments were conducted to investigate fate various crops, including Brassicaceae (pakchoi), Asteraceae (lettuce), Poaceae (wheat maize), Fabaceae (common beans). The evolution bioavailable content pore water its uptake by plants monitored. accumulation, translocation patterns, crop responses based on growth parameters also comprehensively compared among through Mantel test, principal component analysis (PCA), partial least-squares path modeling (PLS-PM). results demonstrated dynamics contents followed a pseudo-second-order reaction model (R2 > 0.95). Pakchoi exhibited highest concentration reaching up 732 ± 137 mg/kg shoots, which are 2.0 4.5 times greater than wheat, with lowest concentration. In pakchoi beans, taken was primarily translocated aboveground parts, factor (TF) ranging from 1.5 4.6, whereas it mainly retained roots other crops. High application (≥3 mg/kg) significantly reduced total dry biomass lettuce 38-50% 22-54%, untreated soil, while markedly increased beans wheat 14-30% 3-29%, respectively. test PCA indicated affected vegetables, showed different response PLS-PM evidenced indirectly shoot regulating root (path coefficient >0.76). high accumulation could be preferable Additionally, this study provides reference understanding soil-plant system, consequently contributing enhancement biofortification strategies.
