Research on dynamics of increments of fir stands revealed a relationship between the stands vitality and the chemical properties of the top layers of mineral soils. Comparison of these two elements and chosen macro and micro-elements in needles of fir indicates perturbations in uptaking of nutrients by roots of trees. These perturbations might be the fundamental causes which have been commonly observed associated with a decreasing of fir stand vitality. Current slow, steadily improvement of fir vitality is associated with chemical changes of the soil.
