We present an elemental profile pattern during the developmental stageof a soybean plant. By neutron activation analysis (NAA), we measured transitionelements, V, Cr, Mn, Fe and Zn. Vanadium and Fe were accumulated in a rootand Cr concentration in a plant was very low throughout the developmentalstage. The concentrations of Mn and Zn in leaves, especially in upper partof the plant, were higher than those in stems. Vanadium treatment inducedlow concentration of Fe in the root.
