“…The fresh litter is also characterized by the quantitative dominance of fungi. The biomass of bacteria increases gradually during decomposition (58,74), as does their diversity (57,72). During decomposition, the abundance of mycophagous bacteria coincides with the peak of fungal biomass in the fresh litter.…”

“…While the acidic soils of coniferous forests harbor mainly Proteobacteria, Acidobacteria, and Actinobacteria (8,55), in temperate deciduous forests, litter bacterial communities seem to be especially enriched with Proteobacteria and Bacteroidetes (45,56,57). Indeed, significant differences in the chemical structure of litter and root exudates among tree species influence soil bacterial communities through changes in substrate chemistry (45,58,59). Litter quality, which includes the quantity of nutrients, tissue structure, and the C/N ratio, varies between tree species and results in varying litter decomposability (60)(61)(62).…”

“…During decomposition, the chemical composition of litter changes with the gradual removal of cellulose, hemicellulose, and lignin (58,71). In contrast to fungi, bacteria inhabiting the phyllosphere of living leaves do not seem to be largely involved in litter decomposition and are quickly replaced by other taxa (72).…”

The ecology of forest soils is an important field of research due to the role of forests as carbon sinks. Consequently, a significant amount of information has been accumulated concerning their ecology, especially for temperate and boreal forests. Although most studies have focused on fungi, forest soil bacteria also play important roles in this environment. In forest soils, bacteria inhabit multiple habitats with specific properties, including bulk soil, rhizosphere, litter, and deadwood habitats, where their communities are shaped by nutrient availability and biotic interactions. Bacteria contribute to a range of essential soil processes involved in the cycling of carbon, nitrogen, and phosphorus. They take part in the decomposition of dead plant biomass and are highly important for the decomposition of dead fungal mycelia. In rhizospheres of forest trees, bacteria interact with plant roots and mycorrhizal fungi as commensalists or mycorrhiza helpers. Bacteria also mediate multiple critical steps in the nitrogen cycle, including N fixation. Bacterial communities in forest soils respond to the effects of global change, such as climate warming, increased levels of carbon dioxide, or anthropogenic nitrogen deposition. This response, however, often reflects the specificities of each studied forest ecosystem, and it is still impossible to fully incorporate bacteria into predictive models. The understanding of bacterial ecology in forest soils has advanced dramatically in recent years, but it is still incomplete. The exact extent of the contribution of bacteria to forest ecosystem processes will be recognized only in the future, when the activities of all soil community members are studied simultaneously.

“…Nevertheless, there are only a few studies of decomposition that have been conducted on afforested postindustrial sites (Dutta & Agrawal, 2001;Horodecki & Jagodziński, 2017;Lawrey, 1977;Singh, Singh, & Tripathi, 1999). A few studies were also concerned with postmining sites left for natural succession (Esperschütz et al, 2013;Frouz, 2008;Urbanová et al, 2014). Surely, decomposition studies on disturbed sites should be developed soon.…”

Advantages of mixed tree stands in restoration of upper soil layers on postmining sites: A five‐year leaf litter decomposition experiment

No in‐depth studies covering litter decomposition were previously conducted on afforested postmining sites despite the importance of litter decomposition on soil formation, especially in degraded areas. We aimed to compare leaf litter decomposition rates of 14 tree species growing in mixed stands on a postmining spoil heap, and to compare their decay rates with those obtained in pure stands of tree species that are very often planted in postmining areas. The study was conducted on the Bełchatów Lignite Mine spoil heap, central Poland. We studied litter decomposition rates over 5 years using the litterbag method. Leaf litter decomposition rates (k constants; yr−1) after 5 years of the experiment were arranged from highest to lowest as follows: Prunus serotina (1.04), Alnus glutinosa (0.86), Fraxinus excelsior (0.81), Ulmus laevis (0.73), Acer pseudoplatanus (0.68), Populus tremula (0.63), Populus × canadensis (0.59), Betula pendula (0.54), Populus nigra ‘Italica’ (0.38), Quercus rubra (0.36), Pinus sylvestris (0.34), Robinia pseudoacacia (0.34), Fagus sylvatica (0.25), and Quercus robur (0.22). Decomposition rates increased with Mg, Ca, and summed Mg + Ca + P + K contents in freshly fallen leaves (%). All species‐specific decomposition rates were higher in mixed than in Scots pine stands. Half of them were also higher than in pure stands of other tree species. Our results indicate that tree species composition could significantly affect the physiochemical properties of upper soil horizons on reclaimed areas. Based on these findings, we recommend planting high share of not only A. pseudoplatanus, A. glutinosa, and U. laevis but also F. sylvatica and Q. robur in stands on postmining spoil heaps, because mixed stands can accelerate soil development more than pure stands.

“…This is of key importance in providing nutrients to trees because a limited amount of nutrients in soil can be replaced by rapid biological cycling of elements. Soil organic matter, even in its initial phase of accumulation, plays an important role in the tree nutrient balance in newly developed ecosystems on reclaimed and afforested post‐mine sites (Roberts et al, 1988; Rumpel et al, 1999; Ellerbrock et al, 1999; Frouz, 2008; Urbanová et al, 2014). Thus, the dynamics of initial soil organic matter accumulation and decomposition is vital to the success of reclamation on post‐mine sites (Roberts et al, 1988; Rumpel et al, 1999; Filcheva et al, 2000; Pietrzykowski and Krzaklewski, 2007).…”

The impact of litter decomposition on chemical substrate properties and element leaching during early soil formation in afforested post-mine sites and the influence of different tree species are key issues in new ecosystem development. Scots pine ( L.) and common birch ( Roth) are important pioneering species used in afforestation of post-mine sites in central and eastern Europe. The aim of this study was to assess the impact of litter decomposition of these species on the chemical properties of mine soil substrates. The impact of litter decomposition on soil properties was tested on quaternary and neogene substrates with different textures (sands, loams, and mixtures of clays and sands) in a controlled incubation experiment using PVC columns. Simulation of precipitation and leaching was undertaken for 10 wk at a temperature of 16°C with distilled water (200 mL wk) through cylinders with litter, substrate + litter, and control substrate (no litter). Filtrated water solution was collected once a week for laboratory analysis, and the concentrations of dissolved organic C, total N, K, Ca, Mg, and P were determined. The study results indicate a stronger impact of the common birch on the chemical properties of reclaimed mine soils compared with pine. After the experiment, birch litter caused significant changes in pH in quaternary sands, concentration of P in quaternary loams (Ql) and mixtures of neogene clays and quaternary sands (QsNc), exchangeable Ca in QsNc, and Mg in Ql and QsNc compared with pine litter. Birch, in comparison to pine, may affect the intensity of early-stage soil-forming processes by increasing nutrient availability and transport into the soil profile, which may affect the development of soil microbial communities. This process results in different soil properties under the two tree species.
