The changes in the availability of selected elements (Ca, Mg, K, Al, As, Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) 16 years after amphibolite treatment were studied in the root zone of spruce (40 and 80 cm from the stem base) using the diffusive gradient in thin film (DGT) technique. The effective concentrations of some of the tested elements significantly increased (Ca (34 %), Mg (31 %), K (65 %), Al (143 %), Fe (242 %), and Pb (27 %)) in 80 cm distance from the stem, whereas the total and the water-soluble concentrations of the elements did not differ from the control. The changes in effective concentrations of the elements in soil were related to higher vitality of the trees on amended soil in contrast to the control.
