  Composited Organic Mobilizing Agents Enhance Cd Accumulation in Sorghum

  To further enhance the efficiency, phytoremediation combined with heavy metal-mobilizing agents has been advocated and attracted research interests in recent years. A pot experiment was conducted with two composited organic agents (oxalic acid or citric acid + dissolved organic fertilizer (OA+DOF and CA+DOF)) and four application periods (seeding, jointing, flag leaf and heading stages) of sorghum (Sorghum bicolor L.), the team of researchers from Institute of Subtropical Agriculture(ISA), Chinese Academy of Sciences to investigate the enhancement effect of composited organic agents on Cd accumulation in shoots at the different growth stages of sorghum.
