“…The bioavailable calcium did not show clear differences between natural stands and spruce plantations. Similar results were also reported by Podrázsky et al (2018), who examined the differences between common fir stands and spruce plantations. A statistically higher share of calcium in the surface soil layer in natural stands was found at the sites Sošice and Ivanec, higher share at the sites Bosiljevo and Medvednica, while at all other sites, the ratio was higher in the spruce plantation (Tab.…”

A quantitative analysis of pedo-physiological indicators aimed at determining changes in the soil attributable to the effects of spruce plantations was done. The study was conducted at eight sites in central and north-western Croatia where spruce plantations were planted in the late 20 th century. At each site, a pedological profile was opened within the spruce plantation and the endomorphological parameters of the soil were determined. Composite soil samples from two depths (0-10 cm and 10-20 cm) and from the forest floor were taken in the spruce plantation and compared with samples taken at plots covered by natural vegetation (natural stands) located in the surroundings. The following pedo-physiographic indicators were measured on the collected soil samples: quantity of forest floor, particle size distribution of soil, pH values in H2O and in CaCl2 aqueous solution (concentration 0.01 mol dm -3 ), content of Corg, content of Ntot and content of bioavailable nutrients (using the Mehlich III method). The results showed that the forest floor had a higher mass in the spruce plantations than in natural stands. The mineral soil showed clear trends of influence of the spruce plantations on soil in terms of reduced pH values. Most plots in the spruce plantations showed a lower nitrogen content in the soil, a higher C/N ratio and lower content of bioavailable phosphorus. This study provides an insight into the amelioration effects of spruce plantations on soil, and represent a reliable basis for decision-making in planning specific interventions in terrestrial ecosystems, such as the establishment of new forest plantations.

“…Also, nutritional imbalances may accelerate the decline and death of climatically stressed trees (Hevia et al 2019;Gonzáles de Andrés et al 2022). Silver fir shows humus forms with lower surface humus accumulation, but with soil chemistry very comparable with that of Norway spruce (Podrázský et al 2018). The importance of impaired nutrition may increase in the future, as the concentration of nutrients in foliage is decreasing in the long term on a European scale (Jonard et al 2015).…”

Silver fir (Abies alba Mill.) is still counted among drought-tolerant tree species. However, its ability to cope with the recent extremely dry period has not yet been sufficiently studied. The objective of research was to analyse differences in the climate-growth response between silver fir, Norway spruce (Picea abies L. Karst.) and European larch (Larix decidua Mill.) growing in areas with large-scale disintegration of spruce stands. In 2019-2021, the increment cores were sampled at 16 sites along the altitudinal gradient of 340-775 m a.s.l. in different regions of the Czech Republic affected by bark beetle outbreak. The radial growth pattern of fir was compared with that of spruce or larch growing under the same site conditions. In fir, the missing rings were frequently recorded during the period of peak SO 2 pollution load in 1966-1985, but they were rarely identified in recent years. In spruce and larch, missing rings were less common and occurred mainly in the recent dry period after 2015. Fir was less sensitive to summer drought compared to larch and especially to spruce, which showed high sensitivity to summer drought regardless of the altitude. The significant positive response of fir to summer precipitation was recorded at sites up to 450 m a.s.l., however, its sensitivity to drought has increased in the last two decades. Hence, when considering the wider use of fir, it is necessary to respect its ecological requirements as much as possible in order to preserve its vitality and production potential in changing climatic conditions.

“…More detailed information about the silver https://doi.org/10.17221/162/2022-JFS fir in the Czech Republic can be found in Novák and Dušek (2021). Increasing the share of fir in forest stands is desirable for several reasons: (i) silver fir is an ecological and functional tree species, which stabilises soil and retains water; (ii) it is less vulnerable to wind and snow or ice breakage than Norway spruce; (iii) it is a very important tree species for maintaining high biodiversity in forest ecosystems; (iv) fir has wide plasticity to environmental conditions and the ability to coexist with many tree species in mixtures due to its ability to survive long periods in the understorey and to respond when light conditions become more favourable; and (v) silver fir is also an economically important tree species (Schütz 2002;Tinner et al 2013;Mauri et al 2016;Dobrowolska et al 2017;Podrázský et al 2018;Schwarz, Bauhus 2019;Walder et al 2021). This explains the increased interest in silver fir and its ecological requirements as well as the possibility of increasing its share in forest stands.…”

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