Accumulation of chemical elements in tree waste of

We investigated the pattern of phosphorus, nitrogen and ashes accumulation in tree waste of Pinus sylvestris L. growing in various ecological zones. The studied areas were located in the Kemerovo Region: on flood-land of the Tom River (the Kuzbass Botanical Garden) and on the waste dump of the Kedrovsky open-cast mine. It was shown that the chemical composition of tree waste of Pinus sylvestris L. is correlated with ecological conditions of its vegetation. So, the tree waste of Pinus sylvestris L. growing on the waste dump is characterized by three-fold increased level of nitrogen compared to ones from the Kuzbass Botanical Garden. The concentration of phosphorus and ashes showed no differences between groups. We suggested that the diversity in destruction of tree waste proceeding in different conditions and microbial cenosis leads to differentiated accumulation of chemical elements in the tree waste
