Other claims from this paper (10)
- Intervention effect Flooding-induced redox decreases had little effect on nickel and cadmium availability in sludge-amended soil.
- Intervention effect Flooding-induced redox decreases increased nickel and cadmium availability in naturally metal-rich soil.
- Association Higher soil-solution nickel and cadmium concentrations were associated with higher concentrations in aerial plant parts.
- Association Oat grain nickel increased with soil-solution nickel.
- Association Oat grain cadmium did not follow the reported increase in grain nickel.
- Association Soil type and sludge amendment strongly affected cadmium in vegetative oat and rye-grass parts.
- Observation Grain nickel concentrations exceeded vegetative-part concentrations in every treatment.
- Observation Vegetative-part cadmium concentrations exceeded grain concentrations in every treatment.
- Association Tissue nickel correlated well with extractable soil nickel but poorly with total soil nickel.
- Recommendation The authors consider total soil-metal content inappropriate for regulating agricultural sludge use.
