High diversity of reference soil groups (RSG) and qualifiers can be found in a small area, and this diversity is not related to the influence of a single but rather to a set of soil-forming factors. As a part of the study, the classification of soils on postglacial landscape was conducted using the WRB 2022 classification system. The analysis was focused on examining relationships between RSG and qualifiers, and also with type of geological deposits, location on the terrain, human activities (drainage of agricultural land, soil tillage and erosion). Survey showed that, in a relatively small area, soil cover consisted of WRB RSG such as Luvisols, Retisols, Regosols, Stagnosols, Gleysols Phaeozems, Planosols, Podzols, Histosols and Anthrosols, with the respective sets of qualifiers. Soils corresponding to the Anthrosol RSG were formed during the construction of a drainage system by burying the former soil with deeper material and later by translocation of colluvium by soil erosion. In the complex glacial topography, the distribution of RSG and their qualifiers is specific, which poses a number of challenges for soil mapping. The study confirmed the possibility of WRB classification for large-scale mapping of agricultural soils on postglacial landscape at the RSG level. The use of qualifiers for definition of mapping units in similar conditions of complex terrain and geological deposits (when mapping on a scale of 1:10 000) is possible only by increasing sampling density.</p></div>","PeriodicalId":9801,"journal":{"name":"Catena","volume":null,"pages":null},"PeriodicalIF":5.4,"publicationDate":"2024-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142011143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We sampled from 0–20 cm, 20–60 cm and 60–100 cm in natural desert (CK) and windproof sand fixation forests after 3, 7, and 10 years of afforestation. The direction of C flow within the aggregates was quantified using the δ¹³C natural abundance method. Results showed that compared to the CK, afforestation increased in the bulk soil OC stock in the 0 − 100 cm by 2.97, 5.34, and 1.67 Mg·ha⁻¹ at 3, 7, and 10 years of afforestation, respectively. The bulk soil OC content decreased gradually, but the stock increased with soil depth. Furthermore, C sequestration in this region mainly relied on the microaggregates OC. Microaggregates acted as both a “source” and a “sink” in desert ecosystems. During the 7 years of afforestation, the δ¹³C in the aggregates decreased with increasing soil depth, indicating older C in the subsoil. The variations in bulk soil OC stock were mainly regulated by ammonium nitrogen, nitrate nitrogen, and total nitrogen. Therefore, the results suggest that 7 years of afforestation may be the optimal choice among the three afforestation years compared for C sequestration.</p></div>","PeriodicalId":9801,"journal":{"name":"Catena","volume":null,"pages":null},"PeriodicalIF":5.4,"publicationDate":"2024-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142007020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hypotheses were: i) the subjectivity leads to variability in the human perception in the qualitative assessment of the cohesive character; ii) it is possible to develop a TS scale that aids in the quantification and diagnosis of the cohesive character. Three evaluators measured the aggregates/clods’ tensile strength using TS-Soil equipment. An electronic dynamometer was used as a control group, using a completely randomized design. The data were analyzed using statistical tests and regression analysis. Additionally, the values assigned in the qualitative evaluation of consistency by the evaluators were related to the tensile strength data. When comparing the means of the evaluators, who used the TS-Soil equipment to quantify the TS of aggregates/clods, with the electronic dynamometer (standard equipment) using the Dunnett test, no significant differences were found in 70 % of the comparisons for horizons with cohesive character and 57 % for horizons without cohesive character. The threshold for diagnosing the cohesive character was set at a TS value 66 kPa (very hard consistency). A significant number of scores were associated with hard consistency (40≤ TS_kPa &lt;66). The study concluded that there is variability in the qualitative assessment of cohesive character and that a TS scale can be useful in quantification and diagnosis. Furthermore, it highlighted the importance of considering a moderate degree of cohesion in taxonomic systems when diagnosing cohesive character. The academic contribution of this study materializes as soil taxonomic systems begin to incorporate quantitative criteria in the diagnosis of cohesive character in soils. As for practical applications, the use of the cohesion degree scale allows the pedologist to recognize the cohesive character in soils more assertively.</p></div>","PeriodicalId":9801,"journal":{"name":"Catena","volume":null,"pages":null},"PeriodicalIF":5.4,"publicationDate":"2024-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142002424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the contributions of accumulated carbon from water to carbon storage and cycling in wetland ecosystems remain unclear. Moreover, there are no comprehensive estimates of the stability and sustainability of wetland performance in retention of carbon from water on different time scales. We conducted a meta-analysis (2889 paired observations) to estimate the stability and sustainability of constructed wetlands in retention of carbon from input water on short and long time scales. This study showed that the efficiency of carbon retention from water in wetlands significantly increased on short time scales, whereas it remained stable on long time scales and among different seasons. The usage of grave, alum sludge and all types of plant had higher effect sizes on short-term wetland water carbon retention, but the long-term stability of water carbon retention was not affected by substrates or plant types. Variations in precipitation as well as air temperature affected the short-term water carbon retention in wetlands, but they did not affect long-term water carbon retention in wetlands. However, on long time scale, the stability of water carbon retention in wetlands was challenged by operation time, low water temperature and high hydraulic load rate, which posed a threat to the sustainability of wetland performance in water carbon retention. In summary, this study demonstrated the stability and sustainability of carbon retention from water and proved the contribution of accumulated carbon from water to the carbon pool in wetland ecosystems.</p></div>","PeriodicalId":9801,"journal":{"name":"Catena","volume":null,"pages":null},"PeriodicalIF":5.4,"publicationDate":"2024-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141998308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we reconstruct vegetation dynamics from the last glacial period using phytoliths as a proxy from the Wanihama loess-paleosol sequence (LPS) near Srinagar in Kashmir Himalaya, India. Different phytolith assemblages and indices (Ic and Iw) revealed a series of warm and cold events documented in the LPS. The data indicate the predominance of broad-leaved and sparse conifer vegetation from ca. 42 ka to 39 ka, suggesting a comparatively warm and humid climate. After ca. 39 ka, conifers and grasses increased, indicating a transition to a cold climate. The cold climate, intervened by a short stadial, continued until ca. 31 ka with the predominance of conifers, grasses, and sedges. Subsequently, three other cold events were noted until ca. 14 ka, which resulted in vegetation disappearance and a substantial decrease in phytolith count. These cold events roughly coincide with the climatic instability in the Atlantic Ocean that caused severe cooling at high northern latitudes and likely impacted the Asian climate. Phytolith assemblages showed an overall increasing proportion of C4 grasses towards the top of the LPS, suggesting warm and dry climatic conditions. We also correlated the phytolith-based vegetation reconstruction with other paleoenvironmental proxies recorded from the same section, as well as with the last glacial climatic changes documented in different regions, to determine the reliability of phytoliths in LPSs as a proxy for past vegetation and climate reconstruction in the Kashmir Himalaya.</p></div>","PeriodicalId":9801,"journal":{"name":"Catena","volume":null,"pages":null},"PeriodicalIF":5.4,"publicationDate":"2024-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141998307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Erosion removes the topsoil, causing lasting changes and exposing tree roots. Yet, little is known about the environmental factors affecting soil erosion rates determined from tree root analysis. This study, exclusively utilizing microscopic preparations, examines tree root anatomical changes on a lowland trail in Brodnica Lakeland. It aims to understand the temporal and spatial variability of soil erosion rates using dendrogeomorphological records of Scots pine (<em>Pinus sylvestris</em> L.) roots. Up to 64 % of samples show exposure due to continuous denudation, significantly shaping the trail’s relief. Abrupt exposures and secondary growth occur in only 22 % and 14 %, respectively. The average soil erosion rate, calculated from 76 root exposures at the Bachotek site, is 1.93 ± 0.82 mm/year, ranging from 0.71 to 3.80 mm/year, with recently exposed roots exhibiting the highest average soil erosion values on the hiking trail. 45 % of root samples exhibit above-average erosion rates. Statistical analyses reveal that erosion rates (ER) are influenced by soil compaction (COM), bulk density (BULK), root orientation (ASP), and exposure length (EXP). Higher compaction and bulk density correlate with increased erosion, while roots parallel to the trail experience more erosion. Conversely, greater root exposure length leads to decreased erosion rates. These findings suggest that soil erosion on the hiking trail primarily results from gradual geomorphological processes. Wood anatomical analyses of pine roots confirm the role of trampling in initiating and accelerating these processes, altering the trail’s subsurface soil layers, and indirectly affecting soil erosion dynamics. Scots pine roots prove valuable as indicators of the temporal and spatial variability of soil erosion along the lowland trail.</p></div>","PeriodicalId":9801,"journal":{"name":"Catena","volume":null,"pages":null},"PeriodicalIF":5.4,"publicationDate":"2024-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141993398","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The rapid decrease in 2000–2004 may be attributed to the construction of dams such as the Three Gorges Dam (TGD). During the pre-TGD period, the terrestrial input maintained stable high values (except for a distinct peak in 1965), which coincided with enhanced chemical weathering, stable annual temperature, increased precipitation, and strong East Asian winter monsoon (EAWM) driven by climatic factors. After <em>ca</em>. 2000, anthropogenic activities gradually became the dominant controlling factor on terrestrial input variations. In addition, significant coastal erosion recorded by Al/Si ratios during 2000–2004 and intensified nearshore eutrophication captured by δ¹⁵N values from 1950 to 1985 are linked to the construction of the TGD and increased fertilizer usage, respectively.

Multi-generational planting (sprouting from logging stumps) of <em>Eucalyptus</em> is widely adopted for timber production in southern China, which distinctly induces the decline of soil properties and destroys soil microbial communities. However, research on various <em>Eucalyptus</em> management practices has predominantly concentrated on soil nutrients and microbial populations. The effects of these practices on soil multifunctionality remain unexplored. Furthermore, the underlying mechanisms influencing the abundant and rare microorganisms have not been fully understood. Here, an 18-year <em>Eucalyptus</em> plantation experiment, including single-generation continuous planting (Y18), multiple-generation felling of the same years (D4), and evergreen broadleaf forest control (CK), was designed. Twenty-three parameters associated with soil nutrient cycling were obtained to quantify soil multifunctionality, and partial least squares path modeling (PLS-PM) was used to reveal the main driving force regulating soil multifunctionality. Our results demonstrated that multi-generational <em>Eucalyptus</em> planting significantly reduced soil multifunctionality, microbial diversity, and network stability. Comparatively, single-generational planting showed slight effects on soil multifunctionality and microbial communities. Stochastic processes dominated the assembly of abundant taxa in <em>Eucalyptus</em> plantations, whereas deterministic processes dominated rare taxa. PLS-PM results revealed that soil organic carbon (SOC), dissolved organic carbon (DOC), total nitrogen (TN), and total phosphorus (TP) directly regulated soil multifunctionality or indirectly through modifying the diversity and networks of rare taxa. The total effect analysis showed that the diversity and network of rare taxa had a greater impact on soil multifunctionality than abundant taxa.
