Özet

High concentrations of heavy metals, low pH and high EC values are the main characteristics of sulphur mine tailings which can cause major revegetation problems. A greenhouse study was conducted by adding various amounts of calcareous soil ( 0, 300 g pot(-1), 600 g pot(-1), 900 g pot(-1) and 1200 g pot(-1)) and farmyard manure ( 0, 36 g pot(-1)) to the sulphur mine tailings to evaluate the amendment effects on revegetation. Zea mays L. (maize) was used as the experimental plant. The results showed that the application of calcareous soil increased pH while it decreased electrical conductivity (EC) and DTPA-extractable concentrations of Fe, Zn, Mn, Cu, Ni, Cr, Pb and Cd in the tailings. Additionally the application demonstrated a decrease in Fe, Zn, Mn, Cu, Ni, Cr, Cd concentrations in the shoots as well as an observed increase in shoot dry weight (g pot(-1)). However, the application of farmyard manure decreased DTPA-extractable concentrations of Zn, Mn, Cu, Ni, Cr, Cd in the tailings and Mn, Cu, Cd concentrations of the shoots only. Calcareous soil and farmyard manure interactions were significant for EC, Ni and Cr concentrations in the tailings and for Cu concentrations of shoots.
