Enhancement of phytoextraction of Zn, Cd, and Cu from calcareous soil: The use of NTA and sulfur amendments

摘要: In a field experiment we investigated the efficiency of two hyperaccumulating species, four agricultural crop plants, and one woody crop, at phytoextraction Zn, Cd, Cu from polluted calcareous soil. addition, examined possibility to enhance these metals by application nitrilotriacetate (NTA) elemental sulfur (S8) Metal uptake species was higher than that but generally low in all treatments compared results reported literature, maybe as result lower total available soil metal concentrations. Soil amended with either S8 or NTA increased solubility (NaNO3-extraction) ions factors 21, 58, 9, respectively, plant accumulation only factor 2−3. As result, even highest removal rates achieved this study were still far what would be required make technique practicable for remediation D...
