Other claims from this paper (11)
- Intervention effect Soil DTPA-extractable Cd increased significantly with Cd application up to 200 mg Cd kg–1 soil.
- Intervention effect Cd application significantly increased Cd content in Indian mustard over the control at every rate.
- Intervention effect Cd uptake by Indian mustard significantly increased over the control at every application rate, from 5.95 to 150.6 μg pot–1 at the highest rate.
- Intervention effect Cd application decreased plant micronutrient content.
- Intervention effect Fe content fell significantly only beyond 50 mg Cd kg–1 soil.
- Intervention effect Total removal of Fe, Zn, and Cu declined significantly at and above 10 mg Cd kg–1 versus control.
- Intervention effect Total Mn removal declined significantly beyond 10 mg Cd kg–1.
- Observation The upper soil threshold for Indian mustard was 3.8 mg kg–1 DTPA-extractable Cd.
- Observation The upper plant Cd threshold for Indian mustard was 28.0 μg Cd g–1 DMY.
- Observation Residual Cd in contaminated soil may remain available for decades.
- Observation Food crops on Cd-contaminated soils may be a significant source of Cd toxicity to humans and grazing animals.
