Organic amendment additions to cadmium-contaminated soils for phytostabilization of three bioenergy crops
Abstract The effects of organic amendments on the phytoremediation of cadmium (Cd) in acacia (Acacia mangium), jatropha (Jatropha curcas), and cassava (Manihot esculenta) were investigated. The bone meal/bat manure and leonardite/bat manure amendments resulted in better growth performance in both ac...

| description | Abstract The effects of organic amendments on the phytoremediation of cadmium (Cd) in acacia (Acacia mangium), jatropha (Jatropha curcas), and cassava (Manihot esculenta) were investigated. The bone meal/bat manure and leonardite/bat manure amendments resulted in better growth performance in both acacia and cassava (growth rate in dry biomass; GRDB 24.2 and 22.2, respectively), while bone meal (GRDB 17.2) was best for jatropha. The lower root/shoot ratio values of jatropha and acacia suggest that these species were better suited than cassava on Cd-contaminated soil. Cassava experienced toxicity symptoms after harvest (3 months). Acacia root accumulated somewhat greater Cd concentrations (up to 5.1 mg kg−1) than cassava and jatropha roots (2.2–3.9 and 2.7–4.1 mg kg−1, respectively). The bone meal and chicken manure (BMCM) treatment for jatropha had the highest bioconcentration factor for root (1.3) and the lowest translocation factor (0.7). Despite the fact that this treatment had substantial Cd concentrations in the soil (3.1 mg kg−1), low Cd accumulation value (3.2 mg kg−1) and the lowest Cd uptake value (127.8 mg plant−1) were observed, clearly indicating that this amendment reduced Cd bioavailability. When growth performance of the study plants is considered, jatropha and acacia may be suitable for phytomanagement of Cd-contaminated soil. |
