In this regard, bioelectrochemical systems (BES) can be hybridized with existing technologies, upgrading the removal performance of original techniques while avoiding replacement costs. Yet, few demonstrations of merged systems have been given. For the first time, in this work it was built a lab-scale model of a BES merged with a secondary settler, namely e-settler, to enhance the polishing performance of already existing WWTPs. In particular, to concomitantly increase nitrogen removal and perform wastewater (WW) disinfection, avoiding further tertiary treatments. In the e-settlers, nitrogen removal was increased through bioelectrochemical stimulation. Concomitant ammonium and nitrate removal without nitrite accumulation and a negligible amount of nitrous oxide emissions were observed. Ti-MMO as anode material showed a high disinfectant action. In conclusion, it was demonstrated how a simple bioelectrochemical set-up can upgrade existing WWTPs. The following step requires the study at a larger scale, identifying optimal operational and structural parameters for the in-situ application. The main limitations of the e-settlers were discussed, linking them to possible solutions that need to be deepened in a lab-scale model of conventional secondary treatments (activated sludge followed by secondary settler) This work was funded through: the ELECTRA project [grant agreement no. 826244], which was financially supported by the Horizon 2020 programme of the European Union; the NSFC-EU Environmental Biotechnology joint program (No. 31861133001); the Key Research and Development Project of Shandong Province (No. 2020CXGC011202).

The bufferstrip was a 3.5\u00a0m wide unfertilised grass strip adjacent to a ditch on an arable field. In total 24 groundwater wells were installed in 4 transects perpendicular to the ditch to determine Cl, NO3 and \u03b415N concentrations. Piezometers were installed to assess the groundwater flow, which was in the direction of the ditch with small downward leakage across a peat layer at about 3\u00a0m depth. Nitrogen was dominantly present as nitrate (NO3). The NO3-N concentrations under the bufferstrip were significantly lower than under the adjacent arable field. The lower concentrations were due to dilution, uptake by grass and denitrification. Nitrate was actively removed in the bufferstrip, since the Cl/NO3 ratios were higher in the bufferstrip than in the remainder of the field. Furthermore, \u03b415N data indicated that denitrification occurred in the groundwater and increased with decreasing distance to the ditch. NO3-N loads to the ditch were estimated at 8.5\u00a0kg\u00a0ha\u22121yr\u22121, which is relatively low for this area. We can, however, not determine whether these relatively low NO3-N loads were causally related to the reduced NO3-N concentrations in the bufferstrip. Nevertheless, the results of the present study are promising and justify additional research on the efficiency of bufferstrips to reduce NO3 concentrations in shallow groundwater, and subsequently reduce NO3 loading of surface water, under Dutch conditions.", "keywords": ["coastal-plain", "Soil Science", "netherlands", "dynamics", "04 agricultural and veterinary sciences", "01 natural sciences", "6.

However, feedbacks between changes in litter input and soil carbon dynamics remain poorly understood in tropical and subtropical forests. This study aims to test whether the effects of litter manipulation on soil respiration differ between natural and plantation forests. Soil respiration, soil properties, fine root biomass and enzyme activity were measured in adjacent plots with doubling vs. eliminating litter input in both natural and plantation forests of Castanopsis carlesii in southern China. After only 3\u00a0years of litter manipulation, the magnitude of change in soil respiration was greater in response to a doubling of the litter input (+24%) than to the elimination of litter input (\u221215%) in the natural forest, possibly due to a positive priming effect on decomposition of soil organic carbon (SOC). The quick and intense priming effect was corroborated by elevated enzyme activities for five of the six enzymes analyzed. In contrast, the response to litter removal (\u221231%) was greater than the response to litter addition (1%; not significant) in the plantation forest. The lack of positive priming in the plantation forest may be related to its lower soil fertility, which could not meet the demand of soil microbes, and to its high clay content, which protected SOC from microbial attack. The positive priming effect in the natural forest but not plantation forest of C. carlesii is also consistent with the significant declines in total soil carbon observed following litter addition in the natural forest but not the plantation forest. Increases in aboveground litter production may trigger priming effects and subsequently transfer more soil carbon to atmospheric CO2 in the natural forest but not in the plantation forest with low fertility. Changes in litter inputs resulting from global change drivers may have different impacts on natural and plantation forests.", "keywords": ["Litter addition", "Carbon cycling", "Subtropical forest", "13.

Species cover was assessed non-destructively before the start of the treatments (1995), at the end of the treatments (1999) and 4 years after the treatments ended (2003). Shrub removal had rather modest effects on heath vegetation, except for mosses which decreased significantly in removal plots. Fertilization decreased the cover of shrubs, mosses, and some graminoids but increased the cover of Festuca rubra. Fertilization converted heath to grassland, but the response of graminoid species was individualistic. Fertilization decreased vascular species richness and evenness, probably through negative effects of shading and litter accumulation on plant growth or recruitment. The vegetation had not recovered completely 4 years after the perturbations had stopped. This suggests that, in contrast to rapid responses to species removal and fertilization, recovery from these perturbations was rather slow, presumably because recovery was affected by long-term biotic interactions and species controls on ecosystem properties.", "keywords": ["0106 biological sciences", "Competition; Empetrum; Facilitation; Removal; Vaccinium", "15.

The use of cover crops could be a potential strategy to ameliorate any adverse effects of residue removal while allowing greater removal levels. Hence, the objective of this study was to determine changes in water erosion potential, soil organic C (SOC) and total N concentration, and crop yields under early- and late-terminated cover crop (CC) combined with five levels of corn residue removal after 3\u00a0years on rainfed and irrigated no-till continuous corn in Nebraska. Treatments were no CC, early- and late-terminated winter rye (Secale cereale L.) CC, and 0, 25, 50, 75, and 100% corn residue removal rates. Complete residue removal reduced mean weight diameter (MWD) of water-stable aggregates (5\u00a0cm depth) by 29% compared to no removal at the rainfed site only, suggesting increased water erosion risk at rainfed sites. Late-terminated CC significantly increased MWD of water-stable aggregates by 27 to 37% at both sites compared to no CC, but early-terminated CC had no effect. The increased MWD with late-terminated CC suggests that CC when terminated late can offset residue removal-induced risks of water erosion. Residue removal and CC did not affect SOC and total soil N concentration. Particulate organic matter increased with late-terminated CC at the irrigated site compared to no CC. Complete residue removal increased irrigated grain yield by 9% in 1\u00a0year relative to no removal. Late-terminated CC had no effect on corn yield except in 1\u00a0year when yield was 8% lower relative to no CC due to low precipitation at corn establishment.

A new two-step method for the synthesis of OCP is proposed: 1) synthesis of brushite from calcium carbonate and phosphoric acid; 2) subsequent hydrolysis of brushite. Fluoride removal experiments are performed in batch-mode using different initial concentrations of fluoride (from 40 to 140 mg/L) and reaction times. Most of fluoride is removed within the first 2 h of all experiments, and the drinkable limit of 1.5 mg/L is reached within a minimum of 3 h for an initial fluoride concentration of 40 mg/L. The experimental fluoride removal capacity of OCP is 25.7 mg/g, and 4 g of OCP can effectively treat 1 L of water with fluoride concentration up to 50 times higher than the drinking limit of 1.5 mg/L.

This review describes the removal of 35 widely used antibiotics in CWTS covering the most common design parameters (flow configuration, substrate, plants) and operational parameters (hydraulic retention time/hydraulic loading rates, feeding mode, aeration, influent quality), and discusses how to tailor those parameters for improving antibiotic removal based on complex removal mechanisms. To achieve an overall efficient removal of antibiotics in CWTS, our principal component analysis indicated that optimization of flow configuration, selection of plant species, and compensation for low microbial activity at low temperature is the priority strategy. For instance, a hybrid-CWTS that integrates the advantages of horizontal and vertical subsurface flow CWTS may provide a sufficient removal performance at reasonable cost and footprint. To target removal of specific antibiotics, future research should focus on elucidating key mechanisms for their removal to guide optimization of the design and operational parameters. More efficient experimental designs (e.g., the Box-Behnken design) are recommended to determine the settings of the key parameters.

Non-thermal plasma (NTP) treatment has demonstrated promising results in terms of PFAS destruction; however, challenges related to scalability, cost, and environmental impact assessment persist. This study conducts a Life Cycle Assessment (LCA) to evaluate the environmental performance of NTP-based technology and its potential for scaling up, based on published laboratory-scale data. Furthermore, a comparison has been made between NTP technology and traditional evaporation and incineration for PFAS removal. Sofia Landfill's leachate treatment facility in Bulgaria served as a case study. The site's leachate treatment facility currently incorporates conventional mechanical and biological treatment processes, with a reverse osmosis (RO) system being planned as a future final step. Three alternatives were evaluated: 1) A1-RO1/P involves the application of plasma treatment to the RO concentrate; 2) A2-RO2/P includes a second-stage RO system with plasma treatment for its concentrate; and 3) A3-RO2/E comprises of a second-stage RO system with concentrate evaporation and off-site incineration of its sludge. The LCA has identified human toxicity potential, freshwater and marine ecotoxicity, freshwater eutrophication and global warming potential as the five key impact categories. The analysis indicates that Bulgaria's electricity mix was the primary impact contributor, followed by transportation. The plasma-based alternatives demonstrated superior performance over the evaporation-incineration alternative, with A2-RO2/P achieving the lowest normalized environmental impact. However, pilot experiments are needed to validate these conclusions.

After 30\u202fdays of incubation, the highest total petroleum hydrocarbons (TPH) removal was observed in microcosms containing digestate together with bulking agent (17.8% and 12.7% higher than control in clay rich soil and sandy soil, respectively) or digestate together with immobilized bacteria (13.4% and 9% higher than control in clay rich soil and sandy soil, respectively). After digestate application microbial respiration was enhanced in sandy soil and inhibited in clay rich soil due to aggregates formation. After bulking agent addition to clay rich soil aggregates size was reduced and oxygen uptake was improved. Application of digestate to soil resulted in the development of distinct microbial groups in amended and non-amended soils. Genera containing species able to degrade TPH like Acinetobacter and Mycobacterium were abundant in digestate and in soil amended with digestate. Quantification of alkB genes, encoding alkane monoxygenase, revealed high concentration of these genes in digestate bacterial community.

The objective for this study was to document corn (Zea mays L.) grain and stover fraction yields, plant nutrient removal and replacement costs, feedstock quality, soil-test changes, and soil quality indicator response to four stover harvest strategies for continuous corn and a corn-soybean [Glycine max. (L.) Merr.] rotation. The treatments included collecting (1) all standing plant material above a stubble height of 10 cm (whole plant), (2) the upper-half by height (ear shank upward), (3) the lower-half by height (from the 10 cm stubble height to just below the earshank), or (4) no removal. Collectable biomass from Treatment 2 averaged 3.9 ({+-}0.8) Mg ha{sup -1} for continuous corn (2005 through 2009), and 4.8 ({+-}0.4) Mg ha{sup -1} for the rotated corn (2005, 2007, and 2009). Compared to harvesting only the grain, collecting stover increased the average N-P-K removal by 29, 3 and 34 kg ha{sup -1} for continuous corn and 42, 3, and 34 kg ha{sup -1} for rotated corn, respectively. Harvesting the lower-half of the corn plant (Treatment 3) required two passes, resulted in frequent plugging of the combine, and provided a feedstockmore\u00a0\u00bb with low quality for conversion to biofuel. Therefore, Treatment 3 was replaced by a 'cobs-only' harvest starting in 2009. Structural sugars glucan and xylan accounted for up to 60% of the chemical composition, while galactan, arabinan, and mannose constituted less than 5% of the harvest fractions collected from 2005 through 2008. Soil-test data from samples collected after the first harvest (2005) revealed low to very low plant-available P and K levels which reduced soybean yield in 2006 after harvesting the whole-plant in 2005. Average continuous corn yields were 21% lower than rotated yields with no significant differences due to stover harvest. Rotated corn yields in 2009 showed some significant differences, presumably because soil-test P was again in the low range. A soil quality analysis using the Soil Management Assessment Framework (SMAF) with six indicators showed that soils at the continuous corn and rotated sites were functioning at an average of 93 and 83% of their inherent potential, respectively. With good crop management practices, including routine soil-testing, adequate fertilization, maintenance of soil organic matter, sustained soil structure, and prevention of wind, water or tillage erosion, a portion of the corn stover being produced in central Iowa, USA can be harvested in a sustainable manner.\u00ab\u00a0less", "keywords": ["2.

In this work, we have conducted the sonochemical treatment of PFOS simulated water under high (500\u00a0kHz) and low (22\u00a0kHz) frequencies while monitoring the operational parameters via an integrated sonochemical system. The integrated advanced sonochemical system includes software to monitor treatment power, solution temperature and frequency while allowing distinctive control of the reaction conditions. Considering the lack of calorimetric measurements in earlier studies and the difficulty in achieving comparative outcomes, precise calorimetric measurements and determination of electrical energy per order (E(EO)) were performed in this study. The complete PFOS removal was achieved under 500\u00a0kHz frequency with optimum parameters including initial pollutant concentration (5\u00a0mg/L), ultrasound power density (400\u00a0W/L) and solution temperature (25\u00a0\u00b0C) within 180\u00a0min of treatment. The removal and mineralization extents (defluorination) were determined by ultra-high performance liquid chromatography\u2013mass spectrometry (UPLC-MS/MS) and ion-chromatography (IC) analysis. Under optimum conditions, 100\u00a0% removal and 99\u00a0% mineralization were achieved. The rate constant (k) ranged from 0.011 to 0.031 [Formula: see text] (first-order reaction), which increased with the increase in the power density. While the solution temperature did not significantly affect the PFOS removal efficiency, the initial concentration was found to have a prominent effect on the reaction rate constant. However, experiments at low frequency (22\u00a0kHz) showed negligible removal efficiency. The specific energy requirement for reaching 90\u00a0% removal while considering the power consumed by the ultrasonic system from the main electrical source was determined to be 700 [Formula: see text] , which is much lower than other reported work under similar conditions.

Nitrate can be cathodically reduced in bioelectrochemical systems using autotrophic denitrifiers with low energy investment and without chemical addition. Successful denitrification was demonstrated in previous studies in both microbial fuel cells and microbial electrolysis cells (MECs) with continuous current flow, whereas the impact of intermittent current supply (e.g., in a fluidized-bed system) on denitrification and particularly the electron-storing capacity of the denitrifying electroactive biofilms (EABs) on the cathodes have not been studied in depth. In this study, two continuously fed MECs were operated in parallel under continuous and periodic polarization modes over 280 days, respectively. Under continuous polarization, the maximum denitrification rate reached 233 g NO3--N/m3/d with 98% nitrate removal (0.6 mg NO3--N/L in the effluent) with negligible intermediate production, while under a 30 s open-circuit/30 s polarization mode, 86% of nitrate was removed at a maximum rate of 205 g NO3--N/m3/d (4.5 mg NO3--N/L in the effluent) with higher N2O production (6.6-9.3 mg N/L in the effluent). Conversely, periodic polarization could be an interesting approach in other bioelectrochemical processes if the generation of chemical intermediates (partially reduced or oxidized) should be favored. Similar microbial communities dominated byGallionellaceaewere found in both MECs; however, swapping the polarization modes and the electrochemical analyses suggested that the periodically polarized EABs probably developed a higher ability for electron storage and transfer, which supported the direct electron transfer pathway in discontinuous operation or fluidized biocathodes.", "keywords": ["bioelectrochemical systems (BESs)", "periodic polarization", "Autotrophic Processes", "Technology and Engineering", "denitrification", "Nitrates", "AUTOTROPHIC DENITRIFICATION", "EABs", "Bioelectric Energy Sources", "NITRATE-CONTAMINATED GROUNDWATER", "02 engineering and technology", "6.

Woody removal often aims to restore the original grassy ecosystem, but few studies have assessed the role of woody removal on ecosystem functions and biodiversity at global scales. We collected data from 140 global studies and evaluated how different woody plant removal methods affected biodiversity (plant and animal diversity) and ecosystem functions (plant production, hydrological function, soil carbon) across global rangelands. Our results indicate that the impact of removal is strongly context dependent, varying with the specific response variable, removal method, and traits of the target species. Over all treatments, woody plant removal increased grass biomass and total groundstorey diversity. Physical and chemical removal methods increased grass biomass and total groundstorey biomass (i.e., non\uffe2\uff80\uff90woody plants, including grass biomass), but burning reduced animal diversity. The impact of different treatment methods declined with time since removal, particularly for total groundstorey biomass. Removing pyramid\uffe2\uff80\uff90shaped woody plants increased total groundstorey biomass and hydrological function but reduced total groundstorey diversity. Environmental context (e.g., aridity and soil texture) indirectly controlled the effect of removal on biomass and biodiversity by influencing plant traits such as plant shape, allelopathic, or roots types. Our study demonstrates that a one\uffe2\uff80\uff90size\uffe2\uff80\uff90fits\uffe2\uff80\uff90all approach to woody plant removal is not appropriate, and that consideration of woody plant identity, removal method, and environmental context is critical for optimizing removal outcomes.

When \uffce\uff94SOC, soil GHG emissions, and agronomic energy usage were used to calculate system GWP, all management systems were net GHG sources.

Using biochar as a soil additive becomes increasingly common as farmers seek methods for soil improvement and climate change adaptation. Concurrently, there is growing interest in quantifying soil organic carbon (SOC) at the level of individual plots to remunerate farmers for their good agricultural practices and the resulting (temporary) carbon dioxide removal (CDR). However, methods currently applied in routine analysis quantify SOC, irrespective of its speciation or origin, and do not allow to distinguish biochar-C from SOC. As certification of PyCCS-derived CDR is already established using another quantification method (i.e., analysis of biochar-C content, tracking and registration of its application, and offsetting of carbon expenditures caused by the PyCCS process), the analysis of biochar-C as part of SOC may result in double counting of CDR. Hence, the objectives of this review are (1) to compare the physicochemical properties and the quantities of biochar and SOC fractions on a global and field/site-specific scale, (2) to evaluate the established methods of SOC and pyrogenic carbon (PyC) quantification with regard to their suitability in routine analysis, and (3) to assess whether double counting of SOC and biochar C-sinks can be avoided via analytical techniques. The methods that were found to have the potential to distinguish between non-pyrogenic and PyC in soil are either not fit for routine analysis or require calibration for different soil types, which is extremely laborious and yet to be established at a commercial scale. Moreover, the omnipresence of non-biochar PyC in soils (i.e., from forest fires or soot) that is indistinguishable from biochar-C is an additional challenge that can hardly be solved analytically. This review highlights the risks and limits of only result-based schemes for SOC certification relying on soil sampling and analysis. Carbon sink registers that unite the (spatial) data of biochar application and other forms of land-based CDR are suggested to track biochar applications and to effectively avoid double counting.</p></article>", "keywords": ["2.

According to the obtained results, biochar produced at a temperature of 575 \uffc2\uffb0C (BPM575) can function as a sufficient sorbent for the removal of Zn, Cd and Pb from a water solution. The presented results do not confirm the effect of competing metal ions on the sorption efficiency of the selected metals by the investigated biochars.

The harvested duckweed was characterised for its mineral composition and protein content. In animal husbandry, trace elements are specifically added to animal feed as micronutrients and, thus, feedstuffs biofortified with essential trace elements can provide added value. Duckweed grown on the tested mixture of swine manure waste streams could be considered as a source of Mn, Zn, and Fe for swine feed, while it is not a source of Cu for swine feed. Moreover, it was observed that As, Cd, and Pb content were below the limits of the feed Directive 2002/32/EC in the duckweed grown on the tested medium.

Flow and water quality samples were collected at the wetland upper and lower locations, and piezometers sampled inside and outside the wetland. A simple dynamic model operating on an hourly time step was used to assess wetland removal performance for key N species. Hourly measurements of inflow, outflow, rainfall and Penman-Monteith evapotranspiration estimates were used to calculate dynamic water balance for the wetland. A dynamic N mass balance was calculated for each N component by coupling influent concentrations to the dynamic water balance and applying a first order areal removal coefficient (k20) adjusted to the ambient temperature. Flow and water quality monitoring showed that wetland was mainly groundwater fed. The concentrations of oxidised nitrogen (NOx-N, Total Organic Nitrogen (TON) and Total-N (TN) were lower at the outlet of the wetland regardless of flow conditions or seasonality, even during winter storms.

Woody removal often aims to restore the original grassy ecosystem, but few studies have assessed the role of woody removal on ecosystem functions and biodiversity at global scales. We collected data from 140 global studies and evaluated how different woody plant removal methods affected biodiversity (plant and animal diversity) and ecosystem functions (plant production, hydrological function, soil carbon) across global rangelands. Our results indicate that the impact of removal is strongly context dependent, varying with the specific response variable, removal method, and traits of the target species. Over all treatments, woody plant removal increased grass biomass and total groundstorey diversity. Physical and chemical removal methods increased grass biomass and total groundstorey biomass (i.e., non\uffe2\uff80\uff90woody plants, including grass biomass), but burning reduced animal diversity. The impact of different treatment methods declined with time since removal, particularly for total groundstorey biomass. Removing pyramid\uffe2\uff80\uff90shaped woody plants increased total groundstorey biomass and hydrological function but reduced total groundstorey diversity. Environmental context (e.g., aridity and soil texture) indirectly controlled the effect of removal on biomass and biodiversity by influencing plant traits such as plant shape, allelopathic, or roots types. Our study demonstrates that a one\uffe2\uff80\uff90size\uffe2\uff80\uff90fits\uffe2\uff80\uff90all approach to woody plant removal is not appropriate, and that consideration of woody plant identity, removal method, and environmental context is critical for optimizing removal outcomes.

From the prism of the sustainable development, reuse of the exhaused SBP contributed to closing material and energy flows. Finding a solution for the reuse of exhausted SBP transforms linear to circular bioeconomy on a micro level. Key role of the application of SBP as biosorbent for metal ions removal has surface of the biomaterial and their textural characteristics. Comprehensive analysis was conducted in this work regarding determining surface of the sugar beet pulp: Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy with energy dispersive X-ray spectrometry (SEM-EDX), thermogravimetric analysis (TGA), Boehm titrations, and detecting the point of zero charge (pHpzc). The texture and surface of SBP were analyzed before and after the applied biosorption process of the removal of molassigenic metal ions (Na+, K+, Ca2+) from the alkalized sugar juice. From the results obtained after the FTIR analysis could be concluded that main centers for the metal ions exchange are carboxyl, hydroxyl and phenyl functional groups. The graph obtained after thermogravimetric analysis confirms presence of the cellulose, hemicellulose and lignin in the structure of the sugar beet pulp which are mainly constructed of the carboxyl groups. Higher presence of the acidic groups on the surface of the sugar beet pulp (1.61mmol/g), than the base (0.25mmol/g), also confirms presence of the acid functional groups, possible proton donors for the exchange with molassigenic metal cations. Aditionally, acidic groups detected by the Boehm titration at the surface of sugar beet pulp after the applied biosorption process is smaller than before the process (1.10mmol/g). The pH working environment in which is conducted experiment (10.5) is convenient for the successful reduction of the present metal ions in alkalized juice, due to the negatively charged surface of the sugar beet pulp in the pH range higher than 10, whereas pHpzc is 6.4. During this biosorption process morphological structure regarding the density of shrinks, cracks and surface smoothness is not changed at the significant level according to SEM micrographs. EDX used as detector, additionaly confirmed increase in the amount of Na+, K+, Ca2+ after the biosorption process at the surface of the sugar beet pulp. Therefore, SBP has appropriate surface structure suitable for the metal ions removal and at the same time process is not harmful to the environment and minimizes the depletion of this by-product from the sugar refinery.", "keywords": ["textural analysis", "8.

Long-term recovery of above- and belowground interactions in restored grassland after topsoil removal and seed addition. Journal of Applied Ecology_  Please cite this paper together with the citation for the datafile.  Study area and experimental design The study was conducted in and around two nature reserves, Eigental and Altl\u00e4ufe der Glatt, which were located approximately 5 km apart (47\u00b027\u00b4 to 47\u00b029\u00b4 N, 8\u00b037\u00b4 to 8\u00b032\u00b4 E, 417 to 572 m a.s.l., Canton of Zurich, Switzerland; Figure S1 and S2, Table S1). Mean annual temperature and precipitation are 9.8 \u00b1 0.6 \u00b0C and 990 \u00b1 168 mm (Kloten climate station 1988-2018; MeteoSchweiz, 2019). TFor this study, we used a space-for-time approach based on eight restoration sites that were between 3 and 32 years old. We measured recovery and restoration success by comparing the restored grasslands with intensively managed and semi-natural grasslands. Using a space-for-time approach requires high similarities in historical properties of the site, such as soil conditions and management regimes, to assure that temporal processes are appropriately represented by spatial patterns (Walker et al., 2010). This was the case in our study. The restored sites had similar soil conditions (i.e., soil type, structure, water availability) as the targeted semi-natural grasslands, while they shared the same agricultural legacy with intensively managed grasslands, i.e., biomass harvest and fertilization (manure and/or slurry) three to five times a year as well as tillage. We randomly established three 5 m x 5 m (25-m2) plots for plant identification and three 2 m x 2 m (4-m2) subplots for soil biotic and abiotic data collection at least 2 m away from the 25-m2 plots in each restoration site. Sites of similar age were grouped into four age classes: Y.4 (3 & 4 years after restoration), Y.18 (17 & 19 years), Y.24 (23 & 25 years), and Y.30 (27 & 32 years). Six intensively managed (Initial) and six semi-natural grassland (Target) sites complemented the experimental set-up, for a total of 36 plots. All plots were sampled under similar conditions, i.e., day of the year, air temperature, soil moisture, and time since last rain event, in June/July 2017 (intensively managed and semi-natural plots) and 2018 (restored plots).  Collection of plants and selected soil biota data Plant species cover (in %) was visually estimated in each 25-m2 plot in mid-June (Braun-Blanquet, 1964; nomenclature: Lauber & Wagner, 1996). We calculated Shannon diversity and assessed plant community structure. We included soil microbial (fungi, procaryotes) and nematodes in our study as they represent the majority of soil biotic diversity and abundance (Bardgett & van der Putten, 2014), cover various trophic levels of the soil food web (Bongers & Ferris, 1999), and play key roles in soil functioning and ecosystem processes (Bardgett & van der Putten, 2014). In particular, soil nematodes were found to be well suited belowground indicators to evaluate recovery/development after restoration (e.g. Frouz, et al. 2008; Kardol et al., 2009; Resch et al., 2019). We randomly collected ten soil cores (2.2 cm diameter x 12 cm depths; sampler from Giddings Machine Company, Windsor, USA) in the 4-m2 subplots to assess soil nematode and microbial (fungal, prokaryotic) diversities and community structures. For soil nematodes, eight of the soil cores were combined and gently homogenized, placed in coolers and stored at 4 \u00b0C and transported to the laboratory (Netherlands Institute of Ecology, NIOO, Wageningen, Netherlands) within three days after collection. Free-living nematodes were extracted from 200 g of fresh soil using Oostenbrink elutriators (Oostenbrink, 1960). After extraction, each sample was divided into three subsamples, two for molecular identification and one to determine nematode abundance (see Resch et al., 2019). For the molecular work, two subsamples were stored in 70% ethanol (final volume 10 mL each) and transported to the laboratory at the Swiss Federal Research Institute WSL (Birmensdorf, Switzerland). Each subsample was reduced to roughly 200 \u03bcL by centrifugation and removal of the supernatant. The remaining ethanol was vaporized (65 \u00b0C for 3 h). Thereafter, 180 \u03bcL ATL buffer solution (Qiagen, Hilden, Germany) was immediately added and samples were stored at 4 \u00b0C until further processing. From these samples, nematode metagenomic DNA was extracted using the DNeasy Blood & Tissue Kit (Qiagen, Hilden, Germany) according to the manufacturer`s protocol, except for the incubation step which was run at 56 \u00b0C for 4 h. PCR amplification of the V6-V8 region of the eukaryotic small-subunit (18S) was performed with 7.5 \u03bcL of genomic DNA template (ca. 1 ng/\u03bcL) in 25 \u03bcL reactions containing 5 \u03bcL PCR reaction buffer, 2.5 mM MgCL2, 0.2 mM dNTPs, 0.8 \u03bcM of each primer (NemF: Sapkota & Nicolaisen, 2015; 18Sr2b: Porazinska et al., 2009), 0.5 \u03bcL BSA, and 0.25 \u03bcL GoTaq G2 Hot Start Polymerase (Promega Corporation, Madison, USA). Amplification was using an initial DNA denaturation step of 95 \u00b0C for 2 min, followed by 35 cycles at 94 \u00b0C for 40 sec, 58 \u00b0C for 40 sec, 72 \u00b0C for 1 min, and a final elongation step at 72 \u00b0C for 10 min. Filtering, dereplication, sample inference, chimera identification, and merging of paired-end reads was implemented using the DADA2 pipeline (v.1.12; Callahan et al., 2016) to finally assign amplicon sequence variants (ASVs) as taxonomic units. We combined and homogenized the remaining two soil cores to assess soil microbes, placed them in coolers (4 \u00b0C) and transported them to the laboratory at WSL. Metagenomic DNA was extracted from 8 g sieved soil (2 mm) using the DNAeasy PowerMax Soil Kit (Qiagen, Hilden, Germany) according to the manufacturer\u00b4s protocol. PCR amplification of the V3-V4 region of the small-subunit (16S) of prokaryotes (i.e., bacteria and archaea) and the ribosomal internal transcribed spacer region (ITS2) of fungi was performed with 1 ng of template DNA using PCR primers and conditions as previously described (Frey et al., 2016). PCRs were run in triplicates, pooled and sent to the Genome Quebec Innovation Centre (Montreal, QC, Canada) for barcoding using the Fluidigm Access Array technology (Fluidigm) and paired-end sequencing on the Illumina MiSeq v3 platform (Illumina Inc., San Diego, USA). Quality filtering, clustering into operational taxonomic units (OTUs, 97% similarity cutoffs) and taxonomic assignment were performed as previously described (Resch et al., 2021).Taxonomic classification of nematode, prokaryotic and fungal sequences was conducted querying against the most recent versions of PR2 (v.4.11.1; Guillou et al., 2013), SILVA (v.132; Quast et al., 2013), and UNITE (v.8; Nilsson et al., 2019) reference sequence databases. Taxonomic assignment cutoffs were set to confidence rankings \u2265 0.8 (below ranked as unclassified). Prokaryotic OTUs assigned to mitochondria or chloroplasts as well as OTUs or ASVs assigned to other than Fungi or Nematoda were manually removed prior to data analysis. The three datasets were filtered to discard singletons and doubletons. Taxonomic abundance matrices were rarefied to the lowest number of sequences per community to achieve parity of the total number of reads between samples (Prokaryotes: 10,929 reads; Fungi: 18,337 reads; Nematodes: 6,662 reads). We calculated Shannon diversity and assessed community structures for soil nematodes, prokaryotes and fungi based on their relative abundances of ASV or OTU at the taxon level.  Collection of soil physical and chemical properties We randomly collected one undisturbed soil core (5 cm diameter, 12 cm depth) per 4-m2 subplot using a steel cylinder that fit into the soil corer. The cylinders were capped to avoid disturbance during transport and used to measure field capacity, rock content and fine earth density as previously described (Resch et al., 2021). We randomly collected another three soil cores (5 cm diameter, 12 cm depths) in each 4-m2 subplot to determine soil chemical properties. The cores were pooled, dried at 60 \u00b0C for 48 h and passed through a 2 mm sieve. We measured soil pH (CaCl2) on dried samples, total nitrogen (N) and organic carbon (C) concentration on dried and fine-ground samples (\u2264 0.5 mm; for details see Resch et al., 2021). We calculated total N and organic C pools after correcting its concentration for soil depth, rock content and fine earth density.", "formats": [{"name": "XLS"}], "keywords": ["bacteria", "biodiversity", "ch", "fungi", "grassland", "nematodes", "plants", "restoration", "soil", "soil-biodiversity", "soil-biology", "soil-chemistry", "topsoil-removal"], "contacts": [{"organization": "Anita C.

From the prism of the sustainable development, reuse of the exhaused SBP contributed to closing material and energy flows. Finding a solution for the reuse of exhausted SBP transforms linear to circular bioeconomy on a micro level. Key role of the application of SBP as biosorbent for metal ions removal has surface of the biomaterial and their textural characteristics. Comprehensive analysis was conducted in this work regarding determining surface of the sugar beet pulp: Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy with energy dispersive X-ray spectrometry (SEM-EDX), thermogravimetric analysis (TGA), Boehm titrations, and detecting the point of zero charge (pHpzc). The texture and surface of SBP were analyzed before and after the applied biosorption process of the removal of molassigenic metal ions (Na+, K+, Ca2+) from the alkalized sugar juice. From the results obtained after the FTIR analysis could be concluded that main centers for the metal ions exchange are carboxyl, hydroxyl and phenyl functional groups. The graph obtained after thermogravimetric analysis confirms presence of the cellulose, hemicellulose and lignin in the structure of the sugar beet pulp which are mainly constructed of the carboxyl groups. Higher presence of the acidic groups on the surface of the sugar beet pulp (1.61mmol/g), than the base (0.25mmol/g), also confirms presence of the acid functional groups, possible proton donors for the exchange with molassigenic metal cations. Aditionally, acidic groups detected by the Boehm titration at the surface of sugar beet pulp after the applied biosorption process is smaller than before the process (1.10mmol/g). The pH working environment in which is conducted experiment (10.5) is convenient for the successful reduction of the present metal ions in alkalized juice, due to the negatively charged surface of the sugar beet pulp in the pH range higher than 10, whereas pHpzc is 6.4. During this biosorption process morphological structure regarding the density of shrinks, cracks and surface smoothness is not changed at the significant level according to SEM micrographs. EDX used as detector, additionaly confirmed increase in the amount of Na+, K+, Ca2+ after the biosorption process at the surface of the sugar beet pulp. Therefore, SBP has appropriate surface structure suitable for the metal ions removal and at the same time process is not harmful to the environment and minimizes the depletion of this by-product from the sugar refinery.", "keywords": ["textural analysis", "8.
