We assessed the phytoextraction potential for Cd of two edible amaranthus herbs (red amaranth: Amaranth Paniculatus L. and green amaranth: Amaranth Paniculatus L.)and the effect of application of N, NP and NPK fertilizers on Cd uptake of the two cultivars from soil contaminated with 5 mg/kg Cd. Two edible amaranthus herbs had high levels of Cd concentration in their tissues, ranging from 124.1 to 225.9 mg/kg in leaves, from 56.2 to 87.6 mg/kg in stems, and from 57.1 to 100.6 mg/kg in roots, resulting in average Bioaccumulation Factors(BCF) ranging from 22.4 to 40.2. Application of N, NP or NPK fertilizers had significantly influenced Cd content in leaves, stems and roots. Fertilizers of NPK fertilizer greatly increased dry biomass, by a factor of 3.5 for red amaranth or 3.2 for green amaranth, resulting in a large increment of Cd uptake per plant. Two edible amaranthus herbs have great potential in phytoremediation of Cd contaminated soil. They have the merits of high Cd content in tissues, high biomass, easy cultivation, and little effect on Cd uptake by fertilization.
