Chromium additions (0-5 ppM Cr(VI)) to soybeans, Glycine max (L) Merrill, grown in nutrient culture resulted in decreased concentrations and total uptake of Ca, K, P, Fe, and Mn in tops and of K, Mg, P, Fe, and Mn in roots. These effects were often apparent at Cr treatments as low as 0.5 ppM. In soil culture Cr additions (0-60 ppM Cr(VI)) appeared to interfere with the accumulation of Ca, K, Mg, P, B, and Cu by soybean tops, with little or no effect on Fe, Mn, or Zn uptake. These effects were generally first observed at the 5-ppM Cr treatment. The initial symptoms of Cr toxicity appeared as severe wilting of tops of treated plants. It could not be concluded from the results of these experiments that Cr, as the hexavalent anion, specifically interfered with uptake of Fe or P by plants, as earlier reported.
