[PDF][PDF] Wheat grain cadmium under long-term fertilization and continuous winter wheat production
5 strong relationship between soil pH and grain Cd in this study may be attributed to the
narrow range of soil pH and grain Cd observed within each experiment. However, when
data from all experiments were combined, soil acidity was shown to have a large effect on
grain Cd. In this study, the maximum Cd accumulation in grain for the wheat cultivar was 52
ppb at soil pH 4.4. This grain Cd is about half the safety limit for Cd in select (continued on
