Other claims from this paper (10)
- Observation Phytoextraction of field crops was rarely an efficient process and required a long time even to remove the bioavailable metal fraction.
- Observation Without assistance, only zinc, manganese and copper were harvested by the canopy of field crops in substantial amounts.
- Observation Rapeseed in the agricultural soil had an estimated maximum removal of about 8 kg of metals per hectare.
- Observation Fodder radish in pyrite waste removed only 0.33 kg of metals per hectare.
- Mechanism Poor above-ground productivity was the main factor constraining metal removals by field crops, especially in wastes.
- Observation Root length and metal uptake by field crops had a close relationship.
- Observation Root growth was a key trait in the selection of field crop species and genotypes.
- Intervention effect Auxins, humic acids and chelators increased metal concentrations in fodder radish tissues.
- Intervention effect Auxins, humic acids and chelators reduced metal removals by fodder radish.
- Recommendation Phytoremediation efficiency with crop species may be improved through increased productivity by suitable soil management, including fertilisation, contaminant dilution, soil capping and metal immobilisation.
