The removal of macro- and trace elements from the soil by aboveground and belowground parts of P. coriarum depended on plant age developmental phase and yield. The removal by the aboveground parts increased steadily during the 1st year of life until the end of vegetation, and in the 2nd and 3rd years achieved the maximum druing budding or blooming; in the belowground parts the maximum content was observed at the end of vegetation in all years of growth. A minimal quantity of macro- and trace elements were removed during the 1st year of life and a maximum in the 3rd year, except for the removal of Zn by the aboveground part and B by the belowground part, the maximums of which were observed in the 2nd year of life. Harvest of the aboveground mass removed 1.2-4.1 times more macroelements and 1.5-9 times more trace elements from the soil than harvest of the belowground part. Of the macroelements, N and K were most removed, while Mn was the trace element most removed.
