“…One interesting approach would be to investigate soil microbial communities and their activities in the two forest types. We found lower soil pH in topsoil in the larch forest than in the mixed forest, confirming a general phenomenon that coniferous forests make the soils acidic (Iwashima et al, 2012; Yang et al, 2015). Soil pH is the master soil property that affects soil microbial activity, decomposition rates, and nutrient (N, phosphorus, and calcium) availability (Högberg et al, 2007; Zhao et al, 2017).…”

Conversion of natural and secondary mixed forests to plantation monocultures can alter soil physical, chemical, and biological properties, which may lead to changes in ecosystem nitrogen (N) status by altering soil N availability. However, assessing and comparing N status between forest types within and across sites remain challenging because different indicators often yield contradicting conclusions. We developed a multiple‐indicator approach to evaluate N status across sites and between larch monocultures and mixed secondary forests paired at three sites (Daxinganling, Maoershan, and Qingyuan) in northeastern China. The selected indicators were foliar N content (%N), soil carbon‐to‐N ratio (C/N), soil inorganic N, foliar 15N natural abundance (δ15N), and δ15N of bulk soil, ammonium, and nitrate in the soil profiles. Our results, as shown mainly by C/N of soil organic layer and the fraction of nitrate in soil inorganic N, showed that N availability increased from north to south in the order Daxinganling < Maoershan < Qingyuan, along with the increasing climatic (mean annual temperature and mean annual precipitation) and N deposition gradients. We also found that the mixed forests had lower N availability than the larch plantations at the two north sites (Daxinganling and Maoershan), while the opposite was found in the south site (Qingyuan). The site‐specific pattern of N availability in the larch versus mixed stands reflects the difference in their succession and management histories. Our study demonstrated that a multiple‐indicator approach is needed for a comprehensive comparison of the N status of different forest types both within and across sites.

“…The litter of the conifer tree has been reported to be more acidic than that of deciduous species (Ranger et al, 2002). Compared with the coniferous forest, the litter in broad-leaved forest has been found to have higher exchangeable cations, for example, Mg2 + and Ca2 + (Iwashima et al, 2012), which can lead to an increase in soil buffering capacity and soil pH (Finzi et al, 1998;TÓTh et al, 2011). During the forest succession from the pure pine forest to eventual broadleaved trees forest, changes in litter input may also be an important cause of increased soil pH.…”

1. Forest succession is a key driver of plant communities and understanding succession is central to forest restoration. Currently, the information on the response of the microbial community to the forest succession process, however, is limited. In the present study, we investigated the dynamics of the soil bacterial community in three forest types undergoing succession caused by pine wilt disease, representing the initial pine forest, gradual mixed pine and broadleaved forest, and eventual broadleaved forest, using Illumina MiSeq coupled with Functional Annotation of Prokaryotic Taxa (FAPROTAX) analysis. 2. The results showed that the soil pH, contents of soil organic carbon (SOC) and soil total nitrogen (TN) increased after the occurrence of initial succession and differed among the forest sites. The mixed pine forest had significantly higher bacteria biomass (p < 0.05), whereas, the total microbial biomass did not differ during the succession. The bacterial community diversity and richness increased significantly following the succession process (p < 0.05). Proteobacteria, Actinobacteria, Acidobacteria and Bacteroidetes were the dominant phyla across the succession, in which the abundance of Bacteroidetes significantly increased (p < 0.05), whereas, Planctomycetes, WPS-2 and Burkholder decreased in abundance after succession occurred (p < 0.05). 3. The three forests formed distinct bacterial community structures during the succession (p < 0.05), whereas, only two functional structures were clustered, in which the mixed and pure broadleaved forest did not differ. The dominant functional groups involved in the C cycle in the initial pure pine forest were replaced gradually by the groups involved in N and S cycles following the subsequent succession. The soil pH, soil TN and SOC were the most important factors affecting the bacterial community and functional structures during the succession. 4. These results indicate that the bacterial community and function shift drastically in the early stages of succession, which reflects the changes in ecological environment caused by succession. The findings provide useful information to better understand the response of microbes to natural forest disturbance and highlight the importance of microbes during forest succession. | 2549 Functional Ecology QU et al.

“…This suggested that, in 2008, Al concentration remained more mobilized in the organic horizons due to the atmospheric acid deposition that occurred during 1980-1990. On the contrary, in 2013 concentration was observed to be accumulated more in H and A horizons under both forest tree species, which resulted from increases in organic acids from the decomposition in the soil and the initial stage of weathering of minerals in mineral phases (Akbar et al 2010;Iwashima et al 2012). On the other hand, Dijkstra and Fitzhugh (2003) reported that it may have originated from Al release after SOM decomposition and also from the increased Al dissolution induced by low soil pH.…”

“…The SOC stabilization takes place according to the abiotic and biotic processes (Campbell and Paustian 2015) and goes through these mechanisms: conservation due to recalcitrance, the interchange of elements, and inaccessibility to the decomposer community due to the occlusion in the aggregate soil (Poirier et al 2018). The content of nutrients such as nitrogen (N), calcium (Ca), potassium (K), and phosphorus (P) in the coniferous forest soils is also likely lower than in deciduous forest soils (Iwashima et al 2012) due to less decomposition and mineralization. It is also shown by Berger et al (2006) that beech had higher Ca content than spruce due to the association with the effect of Ca-pump under beech resulting from transpiration of beech and uptake water from deeper soil horizons, in which the soil solution contains more Ca because of weathering supply of the bedrock.…”

Temporal changes in soil chemical compositions in acidified mountain forest soils of Czech Republic

et al. 2023

The study aimed to investigate the temporal changes of pH, sorption complex, and structure of soil organic matter through the forest soil profile under beech and spruce forests located in Jizera mountains (Czech Republic) and affected by natural and anthropogenic acidification. Soil samples were collected in four different years (2008, 2013, 2015, and 2020) in each horizon: fermented horizons (F), humified horizons (H), organo-mineral horizons (A), and subsurface mineral horizons (B) (cambic or spodic). The cation exchange capacity (CEC), base saturation (BS), exchangeable element contents, pH, and soil organic carbon content (SOC) were determined. The infrared soil spectra were used to calculate indices of potential wettability, aromaticity, and decomposition. Our results showed that most nutrients and aliphatic compounds were retained in the uppermost soil layers. The aromaticity of organic matter increased with depth, while polysaccharides, regarding the decomposition compound, disappeared through the soil horizons. In a long-term observation, SOC content had constantly increased under beech, while spruce remained stable in the organic horizons. Exchangeable element contents increased in each horizon, except for Al and Fe; their content quickly decreased in F horizons and slowly decreased in H horizon under both forest tree species, while the deeper horizons remained constant, but increased in A horizon under spruce. Continuously increasing base cations concentrations in sorption complex of both forest tree species during the study period revealed the effect of forest stand types on acid deposition reduction and mitigation. The temporal changes in CEC, BS, SOC, and soil wettability are more intensive in beech than in spruce forest floor.
