Abstract
In the Ardennes, spruce decline is correlated with Mg deficiency caused by acid rain leaching of soil nutrients, associated with solubilization of Al-containing soil minerals. Laboratory experiments were carried out to measure the uptake and translocation of Ca-45 and Mg-28 by intact roots of spruce seedlings in solutions containing various amounts of added AlCl3. Translocation rates in the various organs of the seedlings were higher for magnesium than for calcium. A 1 mM Al nutrient solution had a much stronger inhibitory effect on uptake and translocation of Mg than it had on Ca. These rate differences result largely from differences in the chemical characteristics of these two elements.
