Nutrition of silver fir (Abies alba Mill.) and its comparison with Norway spruce (Picea abies L. H. Karst) from the same forest sites in the Czech Republic

Forests in central Europe were affected by heavy bark beetle outbreak during the years 2014–2022. Decline of Norway spruce brought other species forest trees, including fir, to fore. The nutritional level silver fir is one studied topics. Needles 14 (NS) – (SF) mixed stands from 4 regions Czech Republic have been sampled survey their nutrition level. Nutrition NS often near or below deficiency limit, while SF was assessed as sufficient good. Differences between both and tree found. drew more nutrients soil profile than on same site. nutrient concentrations needles significant for N, Ca, Mg, Zn S non-significant P K.
