In: Zagazig Journal of agricultural research 2009.v.36(3)Summary: Chelation and complexation of heavy metals were evaluated as practical ways to solubilize, detoxify, and enhance heavy metals accumultion by plants. sunflower (helianthus annuus) was selected as a potential heavy metals accumulator for metals in two selected soils different in texture and contamination levels. to enhance metals phyto-extraction, ammonium nitrate and organic chelators (edta, and citric acid) were added to soils at rates of 0 to 20 mmol kg⁻¹ pots experiment was run for 8 weeks.
