An investigation was conducted to study the interaction between Cd and Ca, Zn and organic matter for Cd-phytoremediation in sunflower on the alluvium soil of the Sheila Dhar Institute (SDI) experimental farm, Allahabad (India). Application of 40 ppm Zn produced 11.18% extra dry matter (DM) content and 5.8% extra seed yield over the control. We recommended 1.0% Ca, 40 ppm Zn and 20 tons/ha of compost to enhance dry matter yield and diminish the Cd accumulation in 15 ppm Cd- ethylenediaminetetraacetic (EDTA)-treated plots up to 1/12 folds in sunflower (<0.21 ppm), which indicated phytoremediation of Cd-contaminated soil through soil-plant-rhizospheric processes.
在印度阿拉哈巴德希拉·达尔研究所（SDI）实验农场的冲积土上，开展了一项研究，以探究镉与钙、锌以及有机物之间的相互作用对向日葵镉植物修复的影响。与对照相比，施加40 ppm锌使干物质（DM）含量额外增加了11.18%，种子产量额外增加了5.8%。我们建议施加1.0%的钙、40 ppm的锌和20吨/公顷的堆肥，以提高干物质产量，并将15 ppm镉-乙二胺四乙酸（EDTA）处理地块中向日葵的镉积累量降低至1/12倍（<0.21 ppm），这表明通过土壤-植物-根际过程对镉污染土壤进行了植物修复。
