Other claims from this paper (8)
- Association In unfertilized plots, needle N, P and K contents of Scots pine decreased by 62-92% during senescence.
- Association Needle dry weight of Scots pine decreased by 19-51% during senescence in unfertilized plots.
- Association In some years, needle Ca, Mn and Zn contents of Scots pine increased during senescence.
- Association In some years, needle Fe, B and Al contents of Scots pine increased during senescence.
- Association In the fertilized pole-stage stand, needle dry weight of Scots pine did not decrease at senescence four years after fertilization.
- Association In the fertilized pole-stage stand, nutrient content decreased less during senescence than in the other years.
- Association In the mature stand, needle dry weight and nutrient changes during senescence showed no clear differences between years or between unfertilized and fertilized plots.
- Mechanism Needle concentrations of the mobile nutrients N, P and K vary seasonally because of retranslocation.
