Szukana fraza: [Abstract = "As compared with the initial values the accumulation of total nitrogen and the content of nutrients increased. A slight decrease in P and K content in soil noted in 2000 could have been associated with an increase in the assimilation of nutritive macroelements by the stand in the successive stages of its development. The results of chemical analyses of pine needles suggest the possible deficiency of nitrogen in the nearest future, its current content varying from 1.01\-1.12% dry weight."]
