Abstract
Effects of sulfur (S) (0, 30 mg S kg−1 soil) supply on cadmium (Cd) uptake into rice when cultivated in low-Cd soil [38.8 μg kg−1 for diethylenetriaminepentaacetic acid (DTPA)–extractable Cd] and in excessive-Cd soil (748.7 μg kg−1 for DTPA-extractable Cd) were investigated in a combined soil–sand culture experiment. The significant difference in the Cd uptake into rice between –S and +S treatments were observed in relation to soil Cd levels. When rice was exposed to excessive Cd soil, application of S restrained the uptake of Cd into rice, the S supply tended to increase Cd uptake into rice when cultivated in low-Cd soil. The possible mechanisms explaining the interactions among soil Cd level, S supply, and Cd accumulation in rice are proposed. These results suggest that S fertilization may be important for the development approaches to reducing Cd accumulation in rice when cultivated Cd-contaminated soils.
