In this study, we tested the effects of different soil zinc concentrations on the accumulation of zinc (Zn) in two plant species: Sorghum bicolor (sorghum) and Chenopodium album (lambsquarters). These plants have the potential to be used for phytoremediation and zinc biofortification in zinc-deficient locations, thus it is important to understand how they react to varying levels of soil zinc. Plants were cultivated in containers for three months in soils with zinc concentrations of 10, 30, 50, 90, 130, and 210 mg Zn per kilogram of soil. Zn concentration in the plants and bio-available Zn in the soils were measured at the conclusion of the growing season in addition to plant height, chlorophyll a/b/total content, biomass, and Zn availability in the soils. Plant height, a and b content, total chlorophyll, and biomass were all found to be significantly (p0.05) reduced with increasing Zn concentration in soil. Soil Zn concentration of 2100 mgzn/kgsoil resulted in a maximum Zn content of 1213 mg/kg in Common lambsquarter
