Description
| - V roce 2003 bylo v porostech břízy na plochách Litvínov (Buttersteig) provedeno meliorační vápnění dolomitickým vápencem v dávkách 0, 1500, 3000 a 6000 kg ha-1 a následně byl po tři roky sledován obsah S, N, P, Ca, Mg, K, Mn, Zn, Cu, Pb, Cd a Al v listech. Výsledky ukázaly současný vliv vápnění a imisí v případě S a N, vyšší obsah Ca a Mg, nižší obsah P a K, mírný pokles obsahu Mn, kolísání obsahu Zn, Cu a Pb, pokles obsahu Cd; obsah Al nebyl ovlivněn.

- In 2003, in birch stands on Litvínov (Buttersteig) plots, reclamation liming was carried out by dolomitic limestone at a rate of 0, 1500, 3000 and 6000 kg ha-1 and the content of S, N, P, Ca, Mg, K, Mn, Zn, Cu, Pb, Cd and Al in leaves was monitored for the following three years. Results showed the present effect of liming and air pollution in case of S and N, higher content of Ca and Mg, lower content of P and K, moderate decline of Mn, fluctuation in the content of Zn, Cu and Pb and decrease in the content of Cd; the content of Al was not affected.
