However, uncertainties persist regarding the extent to which CCs, in co\uffe2\uff80\uff90occurrence with environmental factors, influence SOC responses and associated C pools. We therefore performed a weighted meta\uffe2\uff80\uff90analysis on the effects of CCs on the mineral\uffe2\uff80\uff90associated organic carbon (MAOC), the particulate organic carbon (POC) and the microbial biomass carbon (MBC) pool compared to no CC cultivation in arable cropland. Our study summarized global research of comparable management, with a focus on climatic zones representative of Europe, such as arid, temperate and boreal climates. In this meta\uffe2\uff80\uff90analysis, we included 71 independent studies from 61 articles published between 1990 and June 2023 in several scientific and grey literature databases. Sensitivity analysis was conducted and did not identify any significant publication bias. The results revealed that CCs had an overall statistically significant positive effect on SOC pools, increasing MAOC by 4.8% (95% CI: 0.6%\uffe2\uff80\uff939.4%,                     n                     \uffe2\uff80\uff89=\uffe2\uff80\uff8916), POC by 23.2% (95% CI: 13.9%\uffe2\uff80\uff9334.4%,                     n                     \uffe2\uff80\uff89=\uffe2\uff80\uff8939) and MBC by 20.2% (95% CI: 11.7%\uffe2\uff80\uff9330.7%,                     n                     \uffe2\uff80\uff89=\uffe2\uff80\uff8930) in the top soil, compared to no CC cultivation. Thereby, CCs feed into the stable as well as the more labile C pools. The effect of CCs on MAOC was dependent on soil clay content and initial SOC concentration, whereas POC was influenced by moderators such as CC peak biomass and experiment duration. For MBC, for example, clay content, crop rotation duration and tillage depth were identified as important drivers. Based on our results on the effects of CCs on SOC pools and significant moderators, we identified several research needs. A pressing need for additional experiments exploring the effects of CCs on SOC pools was found, with a particular focus on MAOC and POC. Further, we emphasize the necessity for conducting European studies spanning the north\uffe2\uff80\uff93south gradient. In conclusion, our results show that CC cultivation is a key strategy to promote C accrual in different SOC pools. Additionally, this meta\uffe2\uff80\uff90analysis provides new insights into the state of knowledge regarding SOC pool changes influenced by CCs, offering quantitative summary results and shedding light on the sources of heterogeneity affecting these findings.                   </p", "keywords": ["2.

Carbon isotopic techniques using \uffce\uffb413C were used to track the input of new C into the soil system. At the end of two years, shifts in \uffce\uffb413C content of soil organic matter carbon were observed to a depth of 30 cm. Calculated new C in soil organic matter with grain sorghum was greater for elevated CO2 vs. ambient CO2 (162 and 29 g m\uffe2\uff80\uff932, respectively), but with soybean the new C in soil organic matter was less for elevated CO2 vs. ambient CO2 (120 and 291 g m\uffe2\uff80\uff932, respectively). A significant increase in mineral associated organic C was observed in 1993 which may result in increased soil C storage over the long\uffe2\uff80\uff90term, however, little change in total soil organic C was observed under either plant species.

Ecosystem CO2 and H2O fluxes were measured over several 24\uffe2\uff80\uff90h periods during the 1994 and 1995 growing seasons. Ecosystem CO2 assimilation on a ground area basis decreased with decreasing plant diversity in the first year and this was related to a decline in above\uffe2\uff80\uff90ground plant biomass. In the second year, however, CO2 assimilation was not affected by diversity, and this corresponded to the disappearance of a diversity effect on above\uffe2\uff80\uff90ground biomass. Irrespective of diversity treatment, CO2 assimilation on a ground area basis was linearly related to peak above\uffe2\uff80\uff90ground biomass in both years. Elevated CO2 significantly increased ecosystem CO2 assimilation in both years with no interaction between diversity and CO2 treatment, and no corresponding increase in above\uffe2\uff80\uff90ground biomass. There were no significant effects of diversity on water vapour flux, which was measured only in the second year. There were indications of a small CO2 effect on water vapour flux (3\uffe2\uff80\uff939% lower at elevated CO2 depending on the light level).

Caution is therefore required when extrapolating from short\uffe2\uff80\uff90term measurements to predict long\uffe2\uff80\uff90term responses to global climate change. Our findings are of global significance as increases in atmospheric concentrations of CO2 may, depending on sward composition and fertilizer management, increase greenhouse gas emissions of N2O, thereby exacerbating the forcing effect of elevated CO2 on global climate. Our results suggest that when applying high rates of N fertilizer to grassland systems, Trifolium repens swards, or a greater component of Trifolium in mixed swards, may minimize the negative effect of continued increasing atmospheric CO2 concentrations on global warming.</p>", "keywords": ["13.

With one exception soil respiration rates were not significantly different among the six forest sites (site to site variation) and between the years within the same forest site (interannual variation). Only the respiration rate in the spruce stand at Unterl\uffc3\uffbc\uffc3\uff9f was significant lower than the beech stand at Unterl\uffc3\uffbc\uffc3\uff9f in both years. Soil respiration rates of the sandy sites at Unterl\uffc3\uffbc\uffc3\uff9f were limited by soil moisture during the rather dry and warm summer 1999 while soil respiration at the silty Solling site tended to increase. We found a threshold of \uffe2\uff88\uff9280\uffe2\uff80\uff83kPa at 10\uffe2\uff80\uff83cm depth below which soil respiration decreased with increasing drought. Subsequent wetting of sandy soils revealed high CO2effluxes in the stands at Unterl\uffc3\uffbc\uffc3\uff9f.

For the same reason we expect no effect of elevated CO2and N\uffc2\uffa0deposition on litter decomposition. Net primary production of raised ombrotrophic bogs that are at or close to steady state, is regulated by input of nutrients through atmospheric deposition.

Neither above\uffe2\uff80\uff90ground nor below\uffe2\uff80\uff90ground biomass of the C4 perennial grass was significantly affected by the CO2 treatment. Elevated CO2 did not significantly affect root surface area for any species. Total plant nitrogen was also not statistically different between CO2 treatments for any species, indicating no enhanced uptake of N under elevated CO2. Physiological uptake capacities for NO3 and NH4 were not affected by the CO2 treatment during the second harvest; measurements were not made for the first harvest. However, at the third harvest uptake capacity was significantly decreased in response to elevated CO2 for at least one N form in each species. NO3 uptake rates were lower in A. hymenoides and P. rigida, and NH4 uptake rates were lower in B. rubens at elevated CO2. Nitrogen uptake on a whole root\uffe2\uff80\uff90system basis (NO3+NH4 uptake capacity \uffc3\uff97 root biomass) was influenced positively by elevated CO2 only for A. hymenoides after anthesis. These results suggest that elevated CO2 may result in a competitive advantage for A. hymenoides relative to species that do not increase root\uffe2\uff80\uff90system N uptake capacity. Root respiration measurements normalized to 20 \uffc2\uffb0C were not significantly affected by the CO2 treatment. However, specific root respiration was significantly correlated with either root C\uffe2\uff88\uffb6N ratio or root water content when all data per species were included within a simple regression model. The results of this study provide little evidence for up\uffe2\uff80\uff90regulation of root physiology in response to elevated CO2 and indicate that root biomass responses to CO2 are species\uffe2\uff80\uff90specific.</p>", "keywords": ["0106 biological sciences", "2.

Oak was the most  responsive species to all three treatments; elevated CO2 and irrigation increased biomass by an average of 79% and  41%, respectively, whereas the ozone treatment resulted in a 30% reduction in growth. Significant treatment  interactions in this species demonstrated that CO2 ameliorated and irrigation exacerbated the effects of ozone. For  Scots pine and ash, irrigation and elevated CO2 increased growth by approx. 60% and 20%, respectively, whereas  ozone had no detectable effect on ash and resulted in a 15% reduction in growth of Scots pine. Carbon partitioning  to the shoot was enhanced by both the CO2 and H2O treatments in oak, while branching was also increased in this  species in response to elevated O3, resulting in changes to the allometric relationships. CO2 enhanced leaf  production in oak and Scots pine, and together with the promotion of shoot allocation, this indicates an increased  susceptibility to windthrow. Biomass accumulation expressed as relative growth rate, suggested three different  time\uffe2\uff80\uff90dependent growth responses to elevated CO2; the CO2 fertilization effect was maintained through the third  year of growth in oak, had disappeared in Scots pine and a negative effect was evident in ash. Foliar nitrogen and  chlorophyll concentrations indicated a CO2\uffe2\uff80\uff90induced nitrogen deficiency in oak and ash, but not in Scots pine.  Chlorophyll degradation in response to ozone was observed in oak, an effect that was enhanced by irrigation and  reduced by CO2, presumably through stomatal mediated changes in effective ozone dose. These results therefore  suggest that elevated atmospheric CO2 concentrations will enhance growth of some UK forest tree species,  although this might only be apparent during the juvenile phase. However, nitrogen deficiencies might limit this  enhancement on some sites while changes in allocation and leaf area might promote susceptibility to windthrow.  Elevated CO2 also provides some protection against ozone pollution, especially in combination with limited soil  moisture availability. These interactions between CO2, ozone and water supply should be taken into account when predicting the effects of environmental change on tree growth and forest productivity.</p>", "keywords": ["0106 biological sciences", "15.

Development of aboveground biomass and MOM was dependent on elevation and frequency of tidal inundation. Aboveground biomass ofSpartina alterniflora, which occupied low elevations along tidal creeks and was inundated frequently, developed to levels similar to the natural marsh (750 to 1,300 g/m2) within three years after creation.Spartina cynosuroides, which dominated interior areas of the marsh and was flooded less frequently, required 9 years to consistently achieve aboveground biomass equivalent to the natural marsh (600 to 1,560 g/m2). Aboveground biomass ofSpartina patens, which was planted at the highest elevations along the terrestrial margin and seldom flooded, never consistently developed aboveground biomass comparable with the natural marsh during the 15 years after marsh creation. MOM (0 to 10 cm) generally developed at the same rate as aboveground biomass. Between 1988 and 1998, soil bulk density decreased and porosity and organic C and N pools increased in the created marsh. Like vegetation, wetland soil development proceeded faster in response to increased inundation, especially in the streamside zone dominated byS. alterniflora.We estimated that in the streamside and interior zones, an additional 30 years (nitrogen) to 90 years (organic C, porosity) are needed for the upper 30 cm of created marsh soil to become equivalent to the natural marsh. Wetland soil characteristics of theS. patenscommunity along upland fringe will take longer to develop, more than 200 years. Development of the benthic invertebrate\uffe2\uff80\uff90based food web, which depends on organic matter enrichment of the upper 5 to 10 cm of soil, is expected to take less time. Wetland soil characteristics and functions of created irregularly flooded brackish marshes require longer to develop compared with regularly flooded salt marshes because reduced tidal inundation slows wetland vegetation and soil development. The hydrologic regime (regularly vs. irregularly flooded) of the \uffe2\uff80\uff9ctarget\uffe2\uff80\uff9d wetland should be considered when setting realistic expectations for success criteria of created and restored wetlands.</p>", "keywords": ["13.

Chemical weathering of silicate, carbonate and sulfidebearing rocks releases cations and anions that can consume (or release) atmospheric carbon dioxide (CO2), as well as biologically important nutrients such as phosphorous, iron and silicon, which can impact downstream ecosystems (Figure 1). How these cryospheric weathering processes will respond to future climate-driven changes in permafrost thaw and glacial melt is difficult to predict due to the role of complex forcing mechanisms and feedbacks. Isotope geochemistry utilizes changes in the relative abundance of different isotopes due to physical, chemical and biological reactions, allowing some of the complexities of cryospheric weathering processes to be unpicked. In recent years, there has been an explosion in the range of stable and radiogenic isotope systems used for the study of high-latitude environments, including isotopes of major elements such as carbon, oxygen, and silicon (e.g., Opfergelt et al., 2013; Kutscher et al., 2017), and trace metal isotopes such as strontium (Hindshaw et al., 2014), lithium (Murphy et al., 2019), iron (Zhang et al., 2015), uranium-series (e.g., Arendt et al., 2018) and rare earth elements (e.g., Clinger et al., 2016). This research topic explores some of the developments in high-latitude field and experimental studies that utilize such geochemical tools to trace the degree and nature of weathering reactions that play a critical role in carbon cycling. The nine contributions to the research topic involve the analysis of traditional (C, N, S, O) and non-traditional (Mg, Li, Si, Ge) isotopes from different samples types such as river waters, lake waters, rocks, sediments, or mineral separates from locations both in the Northern (Greenland, Iceland, Canada, Svalbard) and Southern Hemisphere (Patagonia, Antarctica). Two papers use isotope geochemistry to explore organic and inorganic carbon cycling within permafrost and active layer soils. Jones et al. show that biogeochemical processes and decomposition pathways of organic carbon in ice-wedge polygons in Svalbard are dependent upon water and organic carbon content. Sulfur (\u03b434S) and oxygen (\u03b418O) isotopes show that iron and sulfate reduction processes dominate in water saturated, high organic carbon environments, whereas sulfide oxidation dominates in drier areas with less organic carbon.

Composting of organic matter 'exogenous' to soil (such as from municipalities, industries and agriculture sources) is recommended as an effective way to ensure the return of biomass to soil and the return of the soil organic matter losses. The composting of municipal solid wastes is seen as a strategy to divert organic waste materials from landfills. A municipal source-separated solid waste compost was used in a study carried out during 2003-2006 in Southern Italy. An annual tomato-snap bean-lettuce rotation was planted on a sandy loam soil with 26 g kg\u22121 organic carbon under greenhouse conditions. Different rates of compost (15-30-45 t ha\u22121 on a dry weight basis) and combinations of compost at a rate of 15 t ha\u22121 with reduced doses of mineral N fertilizer (1/2 or 1/4 of optimal supply) were compared with an untreated control and a N, P, K fertilized control. We found that: (1) increasing compost rates produced increasing positive soil organic carbon balances. The C conversion efficiency was 23 and 36% with 15 and 30 t ha\u22121, respectively, but declined to 28% with the highest rate of compost. Indeed, the higher the compost amounts applied, the higher the soil organic carbon losses. (2) Under tunnel-greenhouse conditions, all the fertilization strategies, except compost at a rate of 15 t ha\u22121, increased soil nitrate concentrations by up 100 to 400 mg kg\u22121 dry weight of soil, particularly in the spring-summer seasons. In the same period, nitrate contents in the untreated control reached 100 mg kg\u22121. (3) The average yield of marketable tomato for the four-year period was 114 t ha\u22121 and did not vary significantly among treatments. No differences in snap bean yields were detected among the fertilization treatments. In lettuce cultivation, however, 30 and 45 t ha\u22121 of compost yielded more than other treatments. In the tunnel-greenhouse environment, a high initial content of soil organic matter resulted in high vegetable yields over all four years, even without mineral or organic fertilizer supply. However, among the various fertilization strategies, the best solution able to restore annual soil carbon mineralization was the supply of 15 t ha\u22121 of compost. In addition, this rate reduced the hazards linked to the high release of nitrates in soil caused by 30 and 45 t ha\u22121 rates of compost or mineral fertilization.", "keywords": ["2.

Compacted embankment materials are generally partially saturated due to seasonal variation in the water content. At the onset of the overflow process embankments undergo to a wetting process due to the changes at the outer surface boundary conditions (i.e. overflow). Erosion behaviour is known to be a counterbalance between gravity forces and shear erosion forces. However, as the particle size decreases (i.e. clayey soils), gravitational forces become negligible and electrochemical interaction between particles play a dominant role. Clay microstructure (e.g. particle configuration and inter-particle forces) changes with the hydro-mechanical stresses history. Thus, it is necessary to consider the microstructural changes in particle configuration to understand the influence of microstructure on the macroscopic behaviour of clay during erosion. Upon wetting, clay have a swelling/collapse behaviour. This research presents experimental results on erosion of clay samples compacted at the same initial dry density but with different compaction water content. The influence of different wetting times on erosion is also investigated. We show that for a given as-compacted water content, the longer the wetting stage, and hence the higher the sample water content, the more erodible the samples. Additionally, for samples compacted at the same dry density, the ones compacted on the dry side of optimum are more erodible than samples compacted at the optimum water content, despite the lower water content at formation. We hypothesise that this may be due to the formation of a different initial microstructure in sample on the dry side of optimum (i.e. bi-modal pore size distribution). Our results contribute to the fundamental understanding of time-dependent mechanisms that influence erosion of clay embankments during overflow and, hence, to embankment failure.

Currently, geotechnical analysis and design approaches mainly consider the soils either totally dry or totally saturated. Environmental actions, like infiltration due to rainfall, can significantly affect the lateral earth pressure of soils, influencing the performance of both temporary or permanent retaining structures. This paper deals with the investigation of the water retention behaviour of a silty soil for the computation of the soil thrust on a retaining wall during rainfall events. In this regard, the retention property of the involved geomaterial is investigated in laboratory through the combined use of high capacity tensiometers (HCT) and a dew-point hygrometer (WP4C). Considering drying and wetting paths, the experimental results are employed to calibrate the water retention behaviour for the computation of the failure shear strength of the geomaterial. The importance to monitor volume change during the characterization of the water retention behaviour of fine soils is highlighted. A series of analytical uncoupled hydro-mechanical analyses is performed to estimate the changing in the thrust of an unsaturated soil on a retaining wall under several infiltration rates. An appropriate modelling of the soil water retention behaviour is resulted to be crucial for the computation of lateral earth thrust.</p>", "keywords": ["Environmental sciences", "0211 other engineering and technologies", "GE1-350", "02 engineering and technology", "15.

The octacalcium phosphate (OCP), a mineralogical precursor of bio-apatite, is here tested as a fluoride remover. A new two-step method for the synthesis of OCP is proposed; it consists of 1) synthesis of brushite from calcium carbonate and phosphoric acid and, 2) subsequent hydrolysis of brushite. Fluoride removal experiments were performed in batch-mode using 200 mg of OCP in 50 ml solutions with different initial concentrations of fluoride (from 40 to 140 mg/L). Most of fluoride is removed within the first two hours, whereas the WHO limit of 1.5 mg/L is reached within a minimum of 3 hours for a starting Fconcentration of 40 mg/L, and in about 12 hours for a starting F-concentration of 80 mg/L. One gram of OCP can remove up to 26 mg of fluoride. The pH of the solution after the treatment is within the range of drinking water.

The weak-wind stable boundary layer (wwSBL) is poorly described by theory and breaks basic assumptions necessary for observations of turbulence. Understanding the wwSBL requires distributed observations capable of separating between sub-mesoscales and turbulent scales.

Additionally, flights with a fiber-optic cable attached to a tethered balloon (termed FlyFOX, Flying Fiber Optics eXperiment) provide an unprecedentedly detailed view of the boundary layer structure with a resolution of 0.254\uffe2\uff80\uff89m and 10\uffe2\uff80\uff89s between 1 and 200\uffe2\uff80\uff89m height.

Given the simplicity of the system design, SMFCs have great potential to be used for decentralised solutions, especially in areas where access to conventional energy sources is limited. Yet, the high cost to power ratio severely limits the translation of this technology into the market. With the aim of reducing the capital cost, in this study we explore the effect of decreasing the amounts of current collector (CC) on the performance. The results demonstrate that increasing the amount of current collector per surface area of the electrode is not a feasible way of enhancing power densities, as to increase the performance by 20% and 35%, the amount of current collector would have to be increased by 150% and 300%, respectively. This highlights the importance of economic evaluations when optimising the design of a SMFC.</p></article>", "keywords": ["Environmental sciences", "GE1-350", "7.

Des semis ont ete recoltes a intervalle de 5-7 semaines. Le traitement CO 2  a eu un effet positif sur la croissance des semis. Les differences observees dans le poids de la biomasse entre les deux traitements CO 2  ont augmente au cours de la periode d'experimentation. La disponibilite du sol en azote n'a pas affecte la croissance de maniere significative. Neanmoins, la croissance en CO 2  elevee, en combinaison avec des niveaux eleves d'azote, amene une accumulation uniformement plus elevee de biomasse totale en fin d'experience (30-40 %). L'allocation de biomasse entre les differentes parties a ete semblable dans tous les traitements, mais etait sensiblement differente entre les recoltes. Les regimes azotes n'ont pas entraine de difference dans les taux de croissance relative (RGR) et les taux d'assimilation nette (NAR), alors que le traitement de CO 2  avait un effet significatif. A travers toutes les concentrations en CO 2  et les niveaux d'apport azote, il a ete mis en evidence une relation positive entre la masse des plantes et RGR, et cette relation n'a pas differe entre les traitements. La surface specifique de feuille (SLA) a diminue en concentration elevee de CO 2 . Le rapport de la masse de racine fine et de la masse de feuillage a ete augmente en forte concentration en CO 2  et a diminue avec les fortes concentrations en azote. Les semis traites avec une forte concentration en azote en CO 2  ont eu la plus grande croissance en hauteur et en diametre. Les rapports allometriques entre la biomasse de tige et de la racine et entre la croissance en hauteur et en diametre n'ont pas ete sensiblement affectes par une concentration elevee. Les concentrations du feuillage en azote ont ete reduites par les basses concentrations en azote du sol. La concentration en azote des semis diminue avec le temps. La concentration elevee en CO 2  a augmente le rapport C/N de tous les compartiments des semis, en raison de la diminution des concentrations en azote. Les semis soumis a une concentration elevee en CO 2  ont reduit les concentrations en azote comparativement au traitement CO 2  en concentration actuelle, si la comparaison se fait sur une base temporelle, mais sont semblables si l'on compare des semis de hauteurs identiques.", "keywords": ["0301 basic medicine", "0303 health sciences", "03 medical and health sciences", "[SDV.SA.SF] Life Sciences [q-bio]/Agricultural sciences/Silviculture", " forestry", "15.
