37 Conclusions The content of the majority of the analyzed elements in biomass increases with age, with exception of roots where the amount of sodium (Na) and iron (Fe) clearly stabilizes in older age classes. Similar trend can be observed in the case of heavy metals in the litter fall. The content of cadmium (Cd) is lower than the content of lead (Pb) in almost whole plant with exception of bark, where relations are the opposite.

38 Conclusions For the litter fall, a significant drop in most elements can be observed in the initial phase followed by a relatively stable moderate increase. This fact can not be confirmed for the amount of the litter fall, which increases approximately linearly. The share of the foliage biomass in the whole tree biomass decreases with age, and the share of the trunk strongly increases. After initial moderate increase, the share of bark and branches stabilizes. The share of roots also initially decreases and then levels up.

53 Conclusions For litter fall, content of majority of analyzed elements increases in young ages and then decreases. Reverse tendency can be observed for foliage. Amount of carbon sequestered in stems gets higher with tree's age, whereas in roots it decreases. We observed high content of sodium, lead and especially iron in roots. In 2nd age class it reaches over 80%.

54 Conclusions Sodium content in roots significantly decreases with age and increases in stems. Similar pattern of the element transfer from roots to shoots can be seen for copper and, to a less extent, for magnesium, calcium and lead. Copper, zinc and calcium content peaked in the bark. Foliage stores over 50% of magnesium and potassium.
