“…Based on the literature, it is understood that the growth intensity of birch is strongly correlated with nutrient bioavailability, particularly N, P, and potassium (K) (Ingestad 1971;Falkengren-Grerup et al 2006; Uri et al 2007), thus indicating the large potential of their uptake from soil. The soil-plant transfer of nutrients can be effectively accelerated by the root microbiome (e.g., Chojnacka et al 2023). Generally, fresh birch biomass is rich in nutrients.…”

This study was aimed at evaluating the distribution of nutrients in the organs of silver birch growing on extremely nutrient-poor stands associated with inland dunes in central Poland. The study covered three stands, aged 12, 20, and 34 years. Ten average trees were sampled from each stand, including their fine roots, coarse roots, stemwood, bark, coarse branches, fine branches, and leaves. Under each tree, the soils were sampled at depths of 0–10, 10–20, 20–40, and 40–80 cm. The contents of nitrogen (N), phosphorous (P), potassium (K), calcium (Ca), magnesium (Mg), sulfur (S), iron (Fe), manganese (Mn), copper (Cu), and zinc (Zn) were analyzed in the biomass and soil samples. The studied soils were classified as Arenosols; they were strongly acidic and very poor in the studied elements. The nutrient distribution in the birch biomass was highly variable. Most had their highest concentrations in the leaves, followed by the bark (N, S, Cu), roots (P, K, Mg), and branches (Ca). The highest amounts of Fe were in fine roots, whereas Mn and Zn were most abundant in the bark. Wide variability was also apparent in the bioaccumulation factors. These were usually the highest in the leaves or bark and the lowest in the stemwood. Nitrogen showed the highest bioaccumulation intensity among the studied elements, followed by S, Zn, Cu, Mn, and P. The bioaccumulation intensity of the nutrients varied among the stands, in many cases showing significant correlations (both positive and negative) with stand age.

BackgroundSpring rapeseed has developed speci c associations with fungi to adapt to extreme environments on the Qinghai-Tibet Plateau (QTP). However, the correlation among rapeseed, fungi and soil on the QTP remain largely unexplored. MethodsThis study comparatively analyzed the fungal diversity and community in multiple compartment niches (rhizosphere soil, root, stem and leaf) in Brassica rapa L. (Haoyou No. 11) and Brassica napus L. (Qingza No. 4, Qingza No.5, Qingza No. 7, Qingza No. 9, Qingza No. 12 and Qingza No. 15). Internal transcribed spacer (ITS) genes were sequenced by High-throughput Illumina sequencing, followed by function prediction using FUNGuild. ResultsB. napus exhibited higher fungal diversity in plant tissues than B. rapa, while B. rapa demonstrated higher fungal richness in the rhizosphere soil (p < 0.05). Olpidium (66.29%), Lactarius (18.37%), and Verticillium (1.99%) were the most abundant genera, and 46 key genera prevalent in all niches and cultivars.Additionally, 19 biomarkers were identi ed, with Lactarius, Coprinellus, Mortierella and Vishniacozyma signi cantly enriched in cultivars Qingza No. 15, Qingza No. 12, Qingza No. 7, and Qingza No. 4, respectively, while Haoyou No. 11 harbored 15 other genera. Among them, Saprotroph-Symbiotroph (45.00%) as the dominant guild in the rhizosphere soil. Correlation network analysis indicated that the abundant and key genera showed signi cantly positive correlations with yield, and fungal biomarkers may contribute to the promotion of plant growth and stress resistance in rapeseed (p < 0.05). ConclusionsThis study provides valuable insights into the relationship between rapeseed and fungal communities on the QTP.
