Inorganic content (IC) and bulk density vary naturally in peatlands and are among the important parameters governing peat fires. However, their roles in fire emissions remain unknown. In this work, bench-scale burning of sphagnum peat conditioned to different values of IC and bulk densities were conducted in the laboratory environment. Mass loss rate, spread rate and transient emissions of 20 gas species and particles (PM10, PM2.5 and PM1) were simultaneously investigated. We found that peat with 50% moisture content can self-sustain smouldering propagation if IC is less than 40%, or its bulk density is lower than 287.5\u202fkg\u202fm\u22123. Increasing IC or bulk density decreases peat mass loss rate and spread rate. High IC peat releases lower gas fluxes (especially for CH4 and NH3) throughout the experiment. In the ignition stage, increasing IC leads to an increase in particles with diameter between 1 and 2.5\u202f\u03bcm; in the fire spread stage, IC has no influence on the particle fluxes. In contrast, increasing bulk density delays both gas and particle emission fluxes without altering the smoke composition significantly. The fundamental understanding of how soil properties affect peat wildfires facilitates the development of mitigation technologies against haze.", "keywords": ["SHALLOW", "Technology", "Engineering", " Civil", "550", "Inorganic content", "Materials Science", "0904 Chemical Engineering", "TRANSIENT GAS", "Materials Science", " Multidisciplinary", "02 engineering and technology", "Pollutant", "MOISTURE", "Civil Engineering", "01 natural sciences", "630", "COMBUSTION", "Engineering", "0204 chemical engineering", "FIRES", "0105 earth and related environmental sciences", "Multidisciplinary", "Science & Technology", "Civil", "Peat", "15.

Determining the effects of biochar additions on CO2 emissions from semi-arid soils is therefore essential for evaluating the potential of biochar as a climate change mitigation strategy. Here, we measured the CO2 that evolved from semi-arid calcareous soils amended with biochar at rates of 0 and 20tha(-1) in a full factorial combination with three different fertilizers (mineral fertilizer, municipal solid waste compost, and sewage sludge) applied at four rates (equivalent to 0, 75, 150, and 225kg potentially available Nha(-1)) during 182 days of aerobic incubation. A double exponential model, which describes cumulative CO2 emissions from two active soil C compartments with different turnover rates (one relatively stable and the other more labile), was found to fit very well all the experimental datasets. In general, the organic fertilizers increased the size and decomposition rate of the stable and labile soil C pools. In contrast, biochar addition had no effects on any of the double exponential model parameters and did not interact with the effects ascribed to the type and rate of fertilizer. After 182 days of incubation, soil organic and microbial biomass C contents tended to increase with increasing the application rates of organic fertilizer, especially of compost, whereas increasing the rate of mineral fertilizer tended to suppress microbial biomass. Biochar was found to increase both organic and inorganic C contents in soil and not to interact with the effects of type and rate of fertilizer on C fractions. As a whole, our results suggest that the use of biochar as enhancer of semi-arid soils, either alone or combined with mineral and organic fertilizers, is unlikely to increase abiotic and biotic soil CO2 emissions.", "keywords": ["Bioqu\u00edmica", "Mineral fertilizer", "Carbonates", "Waste Disposal", " Fluid", "01 natural sciences", "7.

The present work reports findings from a site near Canberra, Australia, where a pine forest (Pinus radiata) was planted onto a former unimproved pasture site. We report a number of detailed observations seeking to understand the basis of the decline in soil C stocks. This is supported by simulations using the whole-ecosystem carbon and nitrogen cycling model CenW 3.1. The model indicated that over the first 18 years after forest establishment, the site lost about 5.5\u00a0t\u00a0C\u00a0ha\u22121 and 588\u00a0kgN\u00a0ha\u22121 from the soil. The C:N ratio of soil organic matter did not change in a systematic manner over the observational period. Carbon and nitrogen stocks contained in the biomass of the 18-year old pine stand exceeded that of the pasture by 88\u00a0t\u00a0C\u00a0ha\u22121 and 393\u00a0kgN\u00a0ha\u22121. An additional 6.1\u00a0t\u00a0C\u00a0ha\u22121 and 110\u00a0kgN\u00a0ha\u22121 accumulated in above-ground litter. These changes, together with the vertical distribution of carbon and nitrogen in the soil, agreed well with the observation at the site. It was assumed that over 18 years, there was also a loss of 86\u00a0kgN\u00a0ha\u22121 from the ecosystem because of normal gaseous losses during nitrogen turn-over and a small amount of nitrogen leaching. Those losses could not be replenished in the pine system without symbiotic biological nitrogen fixation, and there were no fertiliser additions. A simple mass balance approach indicated that the amount of nitrogen accumulating in plant biomass and the litter layer plus the assumed nitrogen loss from the site matched the amount of nitrogen lost from the soil organic nitrogen pool. This reduction in soil nitrogen, together with an unchanged C:N ratio, provided a simple and internally consistent explanation for the observed reduction of soil carbon after reforestation. It supports the general notion that trends in soil carbon upon land-use change can often be controlled by the possible fates of available soil nitrogen.", "keywords": ["550", "Nitrogen", "CenW", "Reforesting pasture lands", "910", "Carbon inorganic compounds", "01 natural sciences", "Ecosystems", "Nitrogen compounds", "C:N ratio", "Nitrogen fixation", "Pasture", "Biomass", "Reforestation", "0105 earth and related environmental sciences", "Keywords: Biological materials", "Pinus radiata", "Nitrogen cycling models", "modeling", "04 agricultural and veterinary sciences", "15.

In a column experiment, we monitored rhizosphere effects on lime dissolution, CO2 effluxes, and the concentrations of dissolved inorganic carbon (DIC) and dissolved organic carbon (DOC) in leachate from an acidic Kandosol. The experiment consisted of four treatments viz: soil only (control), soil\u00a0+\u00a0lime, soil\u00a0+\u00a0wheat, and soil\u00a0+\u00a0lime\u00a0+\u00a0wheat. We measured CO2-C effluxes at 7, 43 and 98 days after planting (DAP) and leachate was collected at 56 and 101 DAP. The soil CO2-C efflux rate increased significantly with lime addition at 7 and 43 DAP compared to control. At 43 DAP, the largest increase in CO2-C effluxes was observed in the lime\u00a0+\u00a0wheat treatment. However, at 98 DAP similar CO2-C effluxes were observed from wheat and lime\u00a0+\u00a0wheat treatments, suggesting that most of the lime was dissolved in the lime\u00a0+\u00a0wheat treatment. Both DOC and DIC concentrations in the leachate increased significantly with lime and wheat only treatments (cf. control). In contrast to DOC, there was an increase in the DIC concentration in the soil leachate from lime\u00a0+\u00a0wheat treatment columns at 101 DAP (significant wheat\u00a0\u00d7\u00a0lime interaction), thus, accentuating the pronounced role of wheat roots. We conclude that plant mediated dissolution of lime increased the concentration of DIC in the soil leachate, while both liming and presence of plants enhanced DOC leaching.", "keywords": ["2.

We analyzed the impact on SOC of four N fertilization rates (0\uffe2\uff80\uff93270 kg N ha\uffe2\uff88\uff921) and four cropping systems: continuous corn (CC) (Zea mays L.); corn\uffe2\uff80\uff93soybean [Glycine max (L.)

Soils were sampled in 2002, Years 23 and 48 of the experiments located in northeast and north\uffe2\uff80\uff90central Iowa, respectively. The experiments were conducted using a replicated split\uffe2\uff80\uff90plot design under conventional tillage. A native prairie was sampled to provide a reference (for one site only). Cropping systems that contained alfalfa had the highest SOC stocks, whereas the CS system generally had the lowest SOC stocks. Concentrations of SOC increased significantly between 1990 and 2002 in only two of the nine systems for which historical data were available, the fertilized CC and COAA systems at one site. Soil quality indices such as particulate organic carbon (POC) were influenced by cropping system, with CS &lt; CC &lt; CCOA. In the native prairie, SOC, POC, and resistant C concentrations were 2.8, 2.6, and 3.9 times, respectively, the highest values in cropped soil, indicating that cultivated soils had not recovered to precultivation conditions. Although corn yields increased with N additions, N fertilization increased SOC stocks only in the CC system at one site. Considering the C cost for N fertilizer production, N fertilization generally had a net negative effect on C sequestration.</p>", "keywords": ["corn\u2013soybean MAP", "2.

Wie P in Sedimenten gebunden ist, wirkt sich auf dessen Bioverf\u00fcgbarkeit aus. Unter reduzierenden, sulfid-freien Bedingungen kann das eisenhaltige Phosphatmineral Vivianit eine wesentliche Rolle bei der P-Bindung in K\u00fcstensedimenten spielen und somit die Wasserqualit\u00e4t positiv beeinflussen. Trotz der Bedeutung von Vivianit f\u00fcr die Regulierung der P-Verf\u00fcgbarkeit in K\u00fcstensedimenten sind die in-situ Bildung, Zusammensetzung und Stabilit\u00e4t von Vivianit nur unzureichend untersucht. In dieser Doktorarbeit wurden Feldexperimente mit einer Laborstudie kombiniert, um die Bildungs- und Umwandlungsprozesse von Vivianit in gezeitenbeeinflussten Sedimenten und den Einfluss der isomorphen Substitution auf diese Prozesse aufzudecken. Diese Erkenntnisse bieten wertvolle Einblicke in die Prozesse des P-Kreislaufs in K\u00fcstensedimenten und sind bedeutend f\u00fcr die Entwicklung industrieller Anwendungen, die darauf abzielen, den anthropogenen P-Kreislauf zu schlie\u00dfen.   Im ersten Teil der Arbeit wurde eine Methode entwickelt, bei der isotopisch 57Fe-markiertes Ferrihydrit mit dem Sediment vermischt wurde, um die Vivianitbildung in-situ in gezeitenbeeinflussten Sedimenten zu verfolgen. Mit dieser Methode konnte gezeigt werden, dass sich Vivianit innerhalb von sieben Wochen in gezeitenbeeinflussten Sedimenten mit g\u00fcnstigen geochemischen Bedingungen bilden kann. Die Adsorption von Phosphat an Ferrihydrit war ein wesentlicher Vorl\u00e4ufer f\u00fcr die Bildung von Vivianit. Die reduktive Aufl\u00f6sung des Ferrihydrits bildete wahrscheinlich lokale Bedingen, welche n\u00f6tig waren, um die Vivianitbildung auszul\u00f6sen. W\u00e4hrend das gebildete Vivianit nur ein kleiner Teil des Eisen (Fe)-Pools war (bis zu 15%), machte es bis zu 72% des P-Pools aus basierend auf st\u00f6chiometrischen Berechnungen. Diese Ergebnisse zeigen, dass Vivianit eine entscheidende Rolle bei der Regulierung der P-Retention in K\u00fcstensedimenten spielen kann.   In der Umwelt enth\u00e4lt Vivianit h\u00e4ufig andere zweiwertige Kationen, wie Mangan (Mn) und Magnesium (Mg), die in der Kristallstruktur Fe ersetzen. Im zweiten Experiment wurde untersucht, ob Mn oder Mg bei unterschiedlichen Salzgehalten bevorzugt eingebaut wird und wie die isomorphe Substitution die Kristallstruktur und Morphologie ver\u00e4ndert. Die Synthese von neunzehn Vivianiten mit unterschiedlichen Mn- und/oder Mg-Konzentrationen bei verschiedenen Salzgehalten ergab, dass bei niedriger Ionenst\u00e4rke sowohl Mn als auch Mg Fe in der Kristallstruktur gleichwertig ersetzen k\u00f6nnen, wobei Mn bei h\u00f6herer Ionenst\u00e4rke bevorzugt wurde. Vivianit weist zwei unterschiedliche Fe-Atompositionen auf. Die Substitution von Fe durch Mn und/oder Mg fand vorzugsweise an der Atomposition statt, welche Elektronentransfer ausf\u00fchren kann, wodurch Vivianit gegen Oxidation stabilisiert wird. Somit kann sich die isomorphe Substitution wahrscheinlich direkt auf das Oxidationsverhalten von Vivianit auswirken. Au\u00dferdem f\u00fchrte die isomorphe Substitution zu kleineren, raueren Kristallen mit geringerer Kristallinit\u00e4t. Diese beobachteten Ver\u00e4nderungen k\u00f6nnten sich auf die Reaktivit\u00e4t von Vivianit in der Umwelt auswirken, weshalb die isomorphe Substitution bei der Untersuchung der Reaktivit\u00e4t von Vivianit ber\u00fccksichtigt werden sollte.   Umweltver\u00e4nderungen, einschlie\u00dflich des Anstiegs des Meeresspiegels, k\u00f6nnten die Bildung von Sulfid in derzeit nicht sulfidischen Sedimenten, die Vivianit enthalten, verst\u00e4rken und zu thermodynamisch instabilen Bedingungen f\u00fcr Vivianit f\u00fchren. Das letzte Experiment untersuchte die in-situ Stabilit\u00e4t von unsubstituiertem und Mn-Mg-substituiertem Vivianit, gemischt mit Meeressand und mit oder ohne die Zugabe von Kalziumkarbonat. Die Mischungen wurden 56 Tage lang in zwei Gezeitenzonen inkubiert, von denen ein Standort eine niedrige und der andere eine hohe Sulfidkonzentration aufwies. Die Inkubation von unsubstituiertem und Mn-Mg-substituiertem Vivianit bei unterschiedlichen Sulfidkonzentrationen ergab eine teilweise Aufl\u00f6sung von Vivianit, die durch die isomorphe Substitution deutlich verst\u00e4rkt wurde. Der gr\u00f6\u00dfte Teil der verbleibenden Mineralphase wurde weiterhin als Vivianit charakterisiert, was darauf hindeutet, dass ein Teil des Vivianits \u00fcber die Versuchsdauer erhalten blieb. Bei niedrigen Sulfidkonzentrationen war Gr\u00fcner Rost das Hauptumwandlungsprodukt, das wahrscheinlich einen Teil des freigesetzten Phosphats adsorbierte. Bei hohem Sulfidgehalt dominierte die Bildung von Fe-Sulfidmineralen, welche aufgrund der geringen Sorptionskapazit\u00e4t f\u00fcr Phosphat zu einem erh\u00f6hten P-Verlust f\u00fchrte. Ein erh\u00f6htes Sorptionspotenzial f\u00fcr Phosphat durch die Zugabe von Kalziumkarbonat k\u00f6nnte den Phosphatverlust geringf\u00fcgig verringern. Diese Ergebnisse zeigen, dass vivianithaltige Sedimente als Quelle f\u00fcr bioverf\u00fcgbares Phosphat dienen k\u00f6nnen, wenn sich die geochemischen Bedingungen \u00e4ndern.   Diese Arbeit liefert neue experimentelle Ans\u00e4tze zur Untersuchung und Quantifizierung von Umwandlungs- und Bildungsprozessen von Vivianit. Die Ergebnisse zeigen eine schnelle in-situ Bildungskinetik, w\u00e4hrend die Aufl\u00f6sung von Vivianit unter den untersuchten Bedingungen langsam verl\u00e4uft. Die schnelle in-situ Bildungskinetik deutet darauf hin, dass die Vivianitbildung die P-Retention in Umgebungen mit sowohl schwankenden als auch stabilen geochemischen Bedingungen regulieren kann. Die Ver\u00e4nderungen der Kristallstruktur und -morphologie durch isomorphe Substitution erh\u00f6hten das Ausma\u00df der Aufl\u00f6sung und Umwandlung des Vivianits. Aufgrund der langsamen in-situ Aufl\u00f6sung k\u00f6nnte Vivianit bei kurzfristigen Umweltst\u00f6rungen eine stabile P-Retentionsphase darstellen. Langfristig destabilisierende Bedingungen k\u00f6nnten jedoch zu einer vollst\u00e4ndigen Aufl\u00f6sung f\u00fchren und die P-Retentionskapazit\u00e4t des Sediments schw\u00e4chen. Die Ergebnisse unterstreichen die Bedeutung von Vivianit als P-Retentionsphase in salzarmen K\u00fcstensedimenten, k\u00f6nnten aber auch f\u00fcr das Verst\u00e4ndnis von Bildungs- und Umwandlungsprozessen von Vivianit in anderen Umweltsystemen, wie limnischen Sedimenten und B\u00f6den in Feuchtgebieten, von Bedeutung sein. Dar\u00fcber hinaus haben diese Ergebnisse Auswirkungen auf andere Forschungsbereiche, wie die Gew\u00e4ssersanierung und die industrielle P-R\u00fcckgewinnung.", "keywords": ["iron biogeochemistry", "info:eu-repo/classification/ddc/550", "Phosphorus cycling", "Coastal biogeochemistry", "X-ray absorption spectroscopy", "Laboratory experiments", "VIVIANITE (MINERALOGY)", "Field experiments", "6.

Widespread shrub encroachment in global drylands may increase plant  biomass and change soil organic carbon stocks of grassland ecosystems.

We conducted a systematic field survey in 75 pairs of  shrub-encroached grassland and control plots at 25 sites in the grasslands  of the Inner Mongolia Plateau to evaluate how shrub encroachment affects  SIC density (SICD) in these ecosystems. 3. We found that shrub  encroachment significantly reduced SICD in the upper 100 cm (3.85 vs. 4.74  kg C m-2, P &lt; 0.05), especially in the subsurface soil (20-50 cm  layer). The magnitude of SICD changes was related to the change in soil  pH, shrub patch size, and initial SICD, reflecting that the reduction in  SICD might be attributed to the shrub encroachment-related soil  acidification. Our results also revealed that the lost SIC was mainly  released into the atmosphere rather than redistributed into deeper soil  layers. 4. Synthesis.

Considering that a mineral that matched calcite crystal lattice parameters even more closely than HAP would be expected to provide a consolidating action even greater than HAP, in this study aluminum phosphate (AP) was investigated as a potential new consolidant. Indeed, AP has lattice parameters differing from those of calcite by only 1%. The consolidating ability of AP was preliminarily investigated here in comparison with HAP. Both treatments were tested on artificially weathered marble samples, in the view of their application for conservation of sugaring marble. A novel method is also proposed for producing samples with near-surface damage similar to that of sugaring marble in the field. The results of the study point out that the novel weathering method is able to provide samples with tailored gradient in dynamic elastic modulus, closely resembling naturally sugaring marble. The AP treatment was found to significantly improve the dynamic elastic modulus of weathered marble, at least as efficiently as the HAP treatment investigated in this study.

The aim of this study is to provide insights into how ML can predict toxicity using a large but sparse dataset. We developed models to predict LC50-values, based on experimental LC50-data covering 2431 organic chemicals and 1506 aquatic species from the ECOTOX-database. Several well-known ML techniques were evaluated and a new ML model was developed, inspired by recommender systems. This new model involves a simple linear model that learns low-rank interactions between species and chemicals using factorization machines. We evaluated the predictive performances of the developed models based on two validation settings: 1) predicting unseen chemical-species pairs, and 2) predicting unseen chemicals. The results of this study show that ML models can accurately predict LC50-values in both validation settings.

However, to date, few studies have addressed these processes. Here, we use meta-analysis and nationwide-survey datasets to investigate changes in soil inorganic carbon (SIC) stocks in China. We observe an overall decrease in SIC stocks in topsoil (0\uffe2\uff80\uff9330\uffc2\uffa0cm) (11.33\uffc2\uffa0g C m\uffe2\uff80\uff932 yr\uffe2\uff80\uff931) from the 1980s to the 2010s.

The consumption of SIC may offset a large portion of global efforts aimed at ecosystem carbon sequestration, which emphasizes the importance of achieving a better understanding of the indirect coupling mechanisms of nitrogen and carbon cycling and of effective countermeasures to minimize SIC loss.</p", "keywords": ["Carbon sequestration", "Cartography", "China", "Mechanics and Transport in Unsaturated Soils", "Carbonate", "Nitrogen", "Soil Science", "Organic chemistry", "Carbon Dynamics in Peatland Ecosystems", "soil inorganic carbon stocks", "Soil pH", "Environmental science", "Carbon sink", "Agricultural and Biological Sciences", "carbonate", "Engineering", "Soil water", "Soil Carbon Sequestration", "Biology", "global change", "Ecosystem", "Soil acidification", "Civil and Structural Engineering", "Soil science", "2.
