Elemental composition of the needles of Scots pine growing near JSC "Mazeikiu nafta"

The present study is aimed at evaluation of effect of JSC "Mazeikiu nafta" on the content of macro-, micronutrients in the needles of Pinus sylvestris growing in sites with different level of pollutants and located at different distance from JSC "Mazeikiu nafta". On each site eight dominant trees were chosen for element analysis. According to the values of elements defined as optimal for nutrition of the conifers, the needles had deficiencies in the amount of N and in the amount of Cu. Concentration of sulphur in the needles was elevated compared to values defined for the needles collected in unpolluted areas and ranged between 1200 and 1600 μg g-1 d.m. The highest (p
