  The Effect of Varying Soil Organic Levels on Phytoextraction of Cu and Zn uptake, enhanced by chelator EDTA, DTPA, EDDS and Citric Acid, in Sunflower (Helianthus annuus), Chinese Cabbage (Brassica campestris), Cattail (Typha latifolia), and Reed (Phragmites communis)

  Focusing on the influence of organic soil contents on the Phytoextraction of Cu and Zn, assisted by chelators EDTA, DTPA, EDDS, and citric acid, in Sunflower (Helianthus annuus), Chinese Cabbage (Brassica campestris), Cattail (Typha latifolia), and Reed (Phragmites communis), this study demonstrates prominent Cu and Zn uptake enhancement. Soil organic concentration has been shown to be a critical factor in metal uptake and bioavailability in plants. Organic content has less soil nutrients, and less negatively charged functional groups, such as carboxical, phenolical and hydroxyl groups. This allows adsorption of negative free metal cations, and reduces metal mobility. Regardless of various soil organic contents, this study ranks Cattail, Reed, Sunflower, and Chinese Cabbage, in descending order of propagation efficacy. The mechanism of metal is apoplastic transportation. In plant cell.. Read More»
