Influence of Anions on the Uptake of Calcium and Magnesium by Plants and on Calcium and Magnesium Movement in Soils1

  1. J. T. Gillingham and
  2. N. R. Page2



The influence of Cl, NO3, SO4, and PO4 on the uptake of Ca and Mg by sunflowers were studied under greenhouse conditions. Calcium uptake was increased only by Cl and NO3. Magnesium uptake was increased by all anions except Cl. In a lysimeter experiment, the vertical movement of Ca and Mg through the profile and into the leachate by the various anions was in the order of their solubility: NO3 > Cl > SO4 > PO4.
