The field experiments consisted of two Scots pine and four Norway spruce experiments. The treatments, on three replicate 8\u00a0m\u00a0\u2217\u00a08\u00a0m plots in all field experiments, were whole-tree harvesting, i.e. harvesting all the above-ground biomass with no logging residue left on the site (R0), stem-only harvesting, leaving logging residues on the site (R1), and stem-only harvesting with double the amount of logging residues left on the site (R2). In the R1 treatment the amount of logging residue in the spruce stands was 39\u201354\u00a0Mg\u00a0ha\u22121 dry mass and in the pine stands, 11\u201318\u00a0Mg\u00a0ha\u22121 dry mass. Over all sites, logging residues had no consistent effects on seedling growth, amounts of soil carbon and nutrients or organic matter characteristics. In some spruce experiments, however, logging residues increased the average diameter, height and height growth (last three years), as well as the number of seedlings, stem volume and biomass. In pine experiments, logging residues had no effect on tree or stand characteristics. In one pine experiment the amounts of exchangeable base cations increased, and there were also changes in the quality of organic matter: the C/N ratio decreased, and NH4\u2013N, microbial biomass N and C mineralization increased due to residues. In the spruce experiments and the other pine experiment, the effect of logging residues on the soil properties measured was slight. Logging residues did not affect NO3\u2013N concentrations or rates of net nitrification, which in most soils were both negligible. Seedling height and height growth correlated strongly and positively with net N mineralization and its ratio to microbial biomass N. All in all, logging residues improved tree and stand characteristics generally in spruce stands, but the effects on soil properties and processes, if any, occurred mostly in one pine stand. This poor correspondence may point to other changes brought on by the logging residues, such as changes in physical environment or decreased competition with ground vegetation, being more important for seedling growth than nutrient status was.", "keywords": ["0106 biological sciences", "nitrogen cycling", "nutrients", "13.

Elevated CO2 may alter microbial activities that regulate soil N availability by changing the amount or composition of organic substrates produced by roots. Our objective was to determine the potential for elevated CO2 to change N availability in an experimental plant-soil system by affecting the acquisition of root-derived C by soil microbes. We grew Populus tremuloides (trembling aspen) cuttings for 2 years under two levels of atmospheric CO2 (36.7 and 71.5 Pa) and at two levels of soil N (210 and 970 \u00b5g N g-1). Ambient and twice-ambient CO2 concentrations were applied using open-top chambers, and soil N availability was manipulated by mixing soils differing in organic N content. From June to October of the second growing season, we measured midday rates of soil respiration. In August, we pulse-labeled plants with 14CO2 and measured soil 14CO2 respiration and the 14C contents of plants, soils, and microorganisms after a 6-day chase period. In conjunction with the August radio-labeling and again in October, we used 15N pool dilution techniques to measure in situ rates of gross N mineralization, N immobilization by microbes, and plant N uptake. At both levels of soil N availability, elevated CO2 significantly increased whole-plant and root biomass, and marginally increased whole-plant N capital. Significant increases in soil respiration were closely linked to increases in root biomass under elevated CO2. CO2 enrichment had no significant effect on the allometric distribution of biomass or 14C among plant components, total 14C allocation belowground, or cumulative (6-day) 14CO2 soil respiration. Elevated CO2 significantly increased microbial 14C contents, indicating greater availability of microbial substrates derived from roots. The near doubling of microbial 14C contents at elevated CO2 was a relatively small quantitative change in the belowground C cycle of our experimental system, but represents an ecologically significant effect on the dynamics of microbial growth. Rates of plant N uptake during both 6-day periods in August and October were significantly greater at elevated CO2, and were closely related to fine-root biomass. Gross N mineralization was not affected by elevated CO2. Despite significantly greater rates of N immobilization under elevated CO2, standing pools of microbial N were not affected by elevated CO2, suggesting that N was cycling through microbes more rapidly. Our results contained elements of both positive and negative feedback hypotheses, and may be most relevant to young, aggrading ecosystems, where soil resources are not yet fully exploited by plant roots. If the turnover of microbial N increases, higher rates of N immobilization may not decrease N availability to plants under elevated CO2.", "keywords": ["0106 biological sciences", "root-: biomass-", "Ecology and Evolutionary Biology", "nitrogen-fixation", "Environmental-Sciences)", "01 natural sciences", "nitrogen", "biomass-", "nitrogen-cycle", "nitrogen-", "Microorganisms-", "carbon-14", "124-38-9: CARBON DIOXIDE", "C Cycle", "Spermatophytes-", "Spermatophyta-", "Key Words Atmospheric CO2", "Cellular and Developmental Biology", "Populus Tremuloides Michx", "2.

The experiment employed a randomized complete block design with four replicates. Soil samples were taken approximately 5\u00a0years after the N application. The results showed that application of 600\u00a0kg N ha\u20131 significantly increased concentrations of NH4 +-N in 0\u201310\u00a0cm soil compared with the control and application of 300\u00a0kg N ha\u20131. Concentrations of NO3 \u2013-N in soil (both 0\u201310\u00a0cm and 10\u201320\u00a0cm) with an application rate of 600\u00a0kg N ha\u20131 were significantly higher compared with the control. Application of 600\u00a0kg N ha\u20131 significantly increased gross N mineralization and immobilization rates (0\u201310\u00a0cm soil) determined by 15N isotope dilution techniques under anaerobic incubation, compared with the control. However, N application did not significantly affect the concentrations of soil total C and total N. N application appeared to decrease microbial biomass C and N and respiration, and to increase the metabolic quotient (qCO2) in 0\u201310\u00a0cm soil, but these effects were not statistically significant. The lack of statistical significance in these microbial properties between the treatments might have been associated with large spatial variability between the replicate plots at this experimental site.

The stimulation of growth increases the litterfall and imports substrate for soil microorganisms. Microbial biomass forms according to the supply of C and N. The formation of microbial biomass is accompanied by respiratory C losses. The quantity of CO2 efflux depends on the C use efficiency of microbes. When excess N is available, the microbial activity is accelerated and the demand for substrate is high. Litterfall supplies an insufficient amount of C to the soil. In such a case, labile soil C is mineralized and the net effect of N fertilization is a loss of soil C. A strong N fertilization effect on the aboveground biomass can offset the soil C loss. In the case of a low N dosage or high N losses due to leaching or emission of nitrogen oxides, the soil C loss is small. The conceptual model was applied to a case study. The field data, collected over a time span of several decades, could not support sound conclusions on the temporal trend of soil C because the spatial and temporal variability of the chemical data was high.

Calcium-carbonate additions increased soil respiration in the field plots in the SHF; in laboratory incubations, soil respiration was higher in the SHF when soils were fertilised with N, and in THF and LERF after S additions. The addition of N alone or in different combinations generally induced a net immobilisation of soil N. Net nitrification increased during the incubation in SHF and THF soils fertilised with N+P, and in LERF soils fertilised with either N, or P, or CaCO3. In a field experiment using ingrowth bags, a higher fine root production was observed in all forest types when bags were fertilised with CaCl2 or CaCO3, suggesting that Ca may be a limiting nutrient in these soils. Calcium-carbonate addition in a glasshouse bioassay experiment with rice showed an overall positive effect on the survival and growth of the seedlings. In other treatments where soil pH was not raised, the rice showed acute toxicity symptoms, poor root and shoot growth and high mortality.

Alanine, glutamic acid, glycine, isoleucine, leucine, phenylalanine, serine, tryptophan, and valine were the most abundant soil FAA. Organic and conventional soils did not significantly differ in their soil FAA composition and concentrations. Urea significantly modified FAA composition, but only in organic soils, suggesting that urea disrupts microbial structure and/or metabolic pathways in organic soils. Alfalfa and compost did not alter FAA composition and concentrations, indicating that any pulses of amino acids from these materials are short lived. On the contrary, straw significantly increased FAA concentrations after 15\u00a0days, coinciding with an increase in microbial biomass N. FAA concentrations remain low and have a largely constant composition in both organic and conventional soils; however, the addition of some fertilizers can significantly alter FAA composition and concentrations, which may affect the importance of amino acid N in the total N budget of plants.

In this study, we determined the effect of elevated CO 2  on decomposition of grass root material ( Lolium perenne  L.).  14 C-labeled root material, produced under ambient (35\u00a0Pa pCO 2 ) or elevated CO 2  (70\u00a0Pa pCO 2 ) was incubated in soil for 64 days. The soils were taken from a pasture ecosystem which had been exposed to ambient (35\u00a0Pa pCO 2 ) or elevated CO 2  (60\u00a0Pa pCO 2 ) under FACE-conditions for 10 years and two fertilizer N rates: 140 and 560\u00a0kg N ha \u22121 \u00a0year \u22121 . In soil exposed to elevated CO 2 , decomposition rates of root material grown at either ambient or elevated CO 2  were always lower than in the control soil exposed to ambient CO 2 , demonstrating a change in microbial activity. In the soil that received the high rate of N fertilizer, decomposition of root material grown at elevated CO 2  decreased by approximately 17% after incubation for 64 days compared to root material grown at ambient CO 2 . The amount of  14 CO 2  respired per amount of  14 C incorporated in the microbial biomass ( q  14 CO 2 ) was significantly lower when roots were grown under high CO 2  compared to roots grown under low CO 2 . We hypothesize that this decrease is the result of a shift in the microbial community, causing an increase in metabolic efficiency. Soils exposed to elevated CO 2  tended to respire more native SOC, both with and without the addition of the root material, probably resulting from a higher C supply to the soil during the 10 years of treatment with elevated CO 2 . The results show the importance of using soils adapted to elevated CO 2  in studies of decomposition of roots grown under elevated CO 2 . Our results further suggest that negative priming effects may obscure CO 2  data in incubation experiments with unlabeled substrates. From the results obtained, we conclude that a slower turnover of root material grown in an \u2018elevated-CO 2  world\u2019 may result in a limited net increase in C storage in ryegrass swards.", "keywords": ["organic-matter dynamics", "2.

Tree growth measurements in this study were carried out at ages 2, 4, 6, 8 and 10 years, while foliar nutrient analyses were carried out at ages 2, 4, 6 and 10 years. Litter production and litter nitrogen (N) and phosphorus (P) measurements were carried out quarterly over a 15-month period between ages 9 and 10 years. Results showed that total tree growth was still greater in residue-retained treatments compared to the RR0 treatment. However, mean annual increments of diameter at breast height (MAID) and basal area (MAIB) declined significantly after age 4 years to about 68-78% at age 10 years. Declining foliar N and P concentrations accounted for 62% (p < 0.05) of the variation of growth rates after age 4 years, and foliar N and P concentrations were either marginal or below critical concentrations. In addition, litter production, and litter N and P contents were not significantly different among the treatments. This study suggests that the impact of residue retention on tree nutrition and growth rates might be limited over a longer period, and that the integration of alternative forest management practices is necessary to sustain the benefits of harvest residues until the end of the rotation.", "keywords": ["Sylviculture", "2.

We conducted a short-term incubation experiment using two (13)C-labelled biochars produced from wheat or eucalypt shoots, which were incorporated in an aridic arenosol to examine the fate of the labile fraction of biochar-C through the microbial community.

A proportion of the biologically-available fraction of both biochars was rapidly (within three days) utilised by gram positive bacteria.

To assess whether and at what rate C accumulates in the soil of young mangrove forests following afforestation, we conducted a field study at an afforestation project in southeast China, including repeated measures taken over six years at two young forests (consisting of  Kandelia obovata  and  Sonneratia apetala , aged 0\u20136 years old), and also a chronosequence of forests aged 0 (mudflat), 6 (both species), 20 ( S.\u00a0apetala ), and 70 ( K.\u00a0obovata ) years old. In the repeated measures, surface (0\u201310\u00a0cm) soil C concentration (%C of dry soil mass) increased significantly over six years, from 1.14% to 1.52% ( K.\u00a0obovata ) and 1.23% to 1.68% ( S.\u00a0apetala ). The rates of increase did not differ significantly between the two species, despite much greater biomass of  S.\u00a0apetala . In the chronosequence, soil C also increased with age across sites, but only the 70-year-old forest was statistically different, suggesting that localized environmental differences may obscure age-related patterns in soil C.

Our findings derive from a total of 1108 soil cores sampled over 14 permanent plots. The observed pattern in SOC stocks reflects the very different climatic conditions and contrasting soil properties existing along the latitudinal transect. The combined effects of these factors strongly influence vegetation structure. SOC stocks in the first 2\uffc2\uffa0m of soil ranged from 20\uffc2\uffa0Mg\uffc2\uffa0C\uffc2\uffa0ha\uffe2\uff88\uff921 for a Sahelian savanna in Mali to over 120\uffc2\uffa0Mg\uffc2\uffa0C\uffc2\uffa0ha\uffe2\uff88\uff921 for a transitional forest in Ghana. The degree of interdependence between soil bulk density (SBD) and soil properties is highlighted by the strong negative relationships observed between SBD and SOC (r2\uffc2\uffa0&gt;\uffc2\uffa00.84). A simple predictive function capable of encompassing the effect of climate, soil properties and vegetation type on SOC stocks showed that available water and sand content taken together could explain 0.84 and 0.86 of the total variability in SOC stocks observed to 0.3 and 1.0\uffc2\uffa0m depth respectively. Used in combination with a suitable climatic parameter, sand content is a good predictor of SOC stored in highly weathered dry tropical ecosystems with arguably less confounding effects than provided by clay content. There was an increased contribution of resistant SOC to the total SOC pool for lower rainfall soils, this likely being the result of more frequent fire events in the grassier savannas of the more arid regions. This work provides new insights into the mechanisms determining the distribution of carbon storage in tropical soils and should contribute significantly to the development of robust predictive models of biogeochemical cycling and vegetation dynamics in tropical regions.</p>", "keywords": ["550", "Tropical ecosystems", "biotic controls", "West africa", "01 natural sciences", "forest soils", "land-use change", "Precipitation gradient", "Soil bulk density", "senegal", "cycle feedback", "Life Science", "Resistant organic carbon", "organic-matter", "0105 earth and related environmental sciences", "2.

To evaluate the effects of elevated atmospheric CO2on litter chemistry and decomposition, we performed a 111 day laboratory incubation with leaf litter of trembling aspen (Populus tremuloidesMichaux) produced at 36\uffe2\uff80\uff83Pa and 56\uffe2\uff80\uff83Pa CO2and two levels of soil nitrogen (N) availability. Decomposition was quantified as microbially respired CO2and dissolved organic carbon (DOC) in soil solution, and concentrations of nonstructural carbohydrates, N, carbon (C), and condensed tannins were monitored throughout the incubation. Growth under elevated atmospheric CO2did not significantly affect initial litter concentrations of TNC, N, or condensed tannins.

Conventional harvests caused a decrease in carbon storage in the forest floor, but when the whole soil profile was taken into account, we found that this loss in the forest floor was compensated by an accumulation of SOC in deeper soil layers. Conversely, we found that intensive harvests led to SOC losses in all layers of forest soils.

Selective microbial mineralization of litter components and the accumulation of microbial necromass can drive litter compositional change, but the extent to which these mechanisms respond to climate remains poorly understood. We addressed this knowledge gap by studying needle litter decomposition along a boreal forest climate transect. Specifically, we investigated how the composition and/or metabolism of the decomposer community varies with climate, and if that variation is associated with distinct modifications of litter chemistry during decomposition. We analyzed the composition of microbial phospholipid fatty acids (PLFAs) in the litter layer and measured natural abundance &amp;amp;#948;&amp;lt;sup&amp;gt;13&amp;lt;/sup&amp;gt;C&amp;lt;sub&amp;gt;PLFA&amp;lt;/sub&amp;gt; values as an integrated measure of microbial metabolisms. Changes in litter chemistry and &amp;amp;#948;&amp;lt;sup&amp;gt;13&amp;lt;/sup&amp;gt;C values were measured in litterbag experiments conducted at each transect site. A warmer climate was associated with higher litter nitrogen concentrations as well as altered microbial community structure (lower fungi:bacteria ratios) and microbial metabolism (higher &amp;amp;#948;&amp;lt;sup&amp;gt;13&amp;lt;/sup&amp;gt;C&amp;lt;sub&amp;gt;PLFA&amp;lt;/sub&amp;gt;).

This study examined whether N\uffe2\uff80\uff90fertilized grasslands exposed to elevated CO2 sequestered additional C. For 10 years, Lolium perenne, Trifolium repens, and the mixture of L. perenne/T. repens grasslands were exposed to ambient and elevated CO2 concentrations (35 and 60\uffe2\uff80\uff83Pa pCO2). The applied CO2 was depleted in \uffce\uffb413C and the grasslands received low (140\uffe2\uff80\uff83kg\uffe2\uff80\uff83ha\uffe2\uff88\uff921) and high (560\uffe2\uff80\uff83kg\uffe2\uff80\uff83ha\uffe2\uff88\uff921) rates of 15N\uffe2\uff80\uff90labeled fertilizer. Annually collected soil samples from the top 10\uffe2\uff80\uff83cm of the grassland soils allowed us to follow the sequestration of new C in the surface soil layer.

Elevated CO2, N\uffe2\uff80\uff90fertilization rate, and species had no significant effect on total soil C. On average 9.4\uffe2\uff80\uff83Mg new C\uffe2\uff80\uff83ha\uffe2\uff88\uff921 was sequestered, which corresponds to 26.5% of the total C. The mean residence time of the C present in the 0\uffe2\uff80\uff9310\uffe2\uff80\uff83cm soil depth was calculated at 4.6\uffc2\uffb11.5 and 3.1\uffc2\uffb11.1 years for L. perenne and T. repens soil, respectively. After 10 years, total soil N and C in the 0\uffe2\uff80\uff9375\uffe2\uff80\uff83cm soil depth was unaffected by CO2 concentration, N\uffe2\uff80\uff90fertilization rate and plant species. The total amount of 15N\uffe2\uff80\uff90fertilizer sequestered in the 0\uffe2\uff80\uff9375\uffe2\uff80\uff83cm soil depth was also unaffected by CO2 concentration, but significantly more 15N was sequestered in the L. perenne compared with the T. repens swards: 620 vs. 452\uffe2\uff80\uff83kg\uffe2\uff80\uff83ha\uffe2\uff88\uff921 at the high rate and 234 vs. 133\uffe2\uff80\uff83kg\uffe2\uff80\uff83ha\uffe2\uff88\uff921 at the low rate of N fertilization. Intermediate values of 15N recovery were found in the mixture. The fertilizer derived N amounted to 2.8% of total N for the low rate and increased to 8.6% for the high rate of N application. On average, 13.9% of the applied 15N\uffe2\uff80\uff90fertilizer was recovered in the 0\uffe2\uff80\uff9375\uffe2\uff80\uff83cm soil depth in soil organic matter in the L. perenne sward, whereas 8.8% was recovered under the T. repens swards, indicating that the N2\uffe2\uff80\uff90fixing T. repens system was less effective in sequestering applied N than the non\uffe2\uff80\uff90N2\uffe2\uff80\uff90fixing L. perenne system. Prolonged elevated CO2 did not lead to an increase in whole soil profile C and N in these fertilized pastures.

Boreal forest soils are globally an important sink for methane (CH4), while these soils are also capable of emitting CH4 under favourable conditions. Soil wetness is a well-known driver of CH4 flux, and the wetness can be estimated with several terrain indices developed for the purpose. The aim of this study was to quantify the spatial variability of the forest floor CH4 flux with a topography-based upscaling method connecting the flux with its driving factors. We conducted spatially extensive forest floor CH4 flux and soil moisture measurements, complemented by ground vegetation classification, in a boreal pine forest. We then modelled the soil moisture with a random forest model using digital-elevation-model-derived topographic indices, based on which we upscaled the forest floor CH4 flux. The modelling was performed for two seasons: May\uffe2\uff80\uff93July and August\uffe2\uff80\uff93October. Additionally, we evaluated the number of flux measurement points needed to get an accurate estimate of the flux at the whole study site merely by averaging. Our results demonstrate high spatial heterogeneity in the forest floor CH4 flux resulting from the soil moisture variability as well as from the related ground vegetation.

The spatial variability in the soil moisture and consequently in the CH4 flux was higher in the early summer (modelled range from \uffe2\uff88\uff9212.3 to 6.19\uffe2\uff80\uff89\uffc2\uffb5mol\uffe2\uff80\uff89m\uffe2\uff88\uff922\uffe2\uff80\uff89h\uffe2\uff88\uff921) compared to the autumn period (range from \uffe2\uff88\uff9214.6 to \uffe2\uff88\uff922.12\uffe2\uff80\uff89\uffc2\uffb5mol\uffe2\uff80\uff89m\uffe2\uff88\uff922\uffe2\uff80\uff89h\uffe2\uff88\uff921), and overall the CH4 uptake rate was higher in autumn compared to early summer. In the early summer there were patches emitting high amounts of CH4; however, these wet patches got drier and smaller in size towards the autumn, changing their dynamics to CH4 uptake. The mean values of the measured and modelled CH4 fluxes for the sample point locations were similar, indicating that the model was able to reproduce the results. For the whole site, upscaling predicted stronger CH4 uptake compared to simply averaging over the sample points. The results highlight the small-scale spatial variability of the boreal forest floor CH4 flux and the importance of soil chamber placement in order to obtain spatially representative CH4 flux results. To predict the CH4 fluxes over large areas more reliably, the locations of the sample points should be selected based on the spatial variability of the driving parameters, in addition to linking the measured fluxes with the parameters.                     </p>", "keywords": ["QE1-996.5", "BOREAL FEN", "Ecology", "methane", "EDDY COVARIANCE", "NITROUS-OXIDE", "Geology", "15.

In this study, we evaluate the feasibility of the proposed soil C loss indicator by assessing its performance using the EU-wide 2009 LUCAS soil survey data. The proposed indicator is the soil organic carbon (SOC) to clay ratio, with a threshold value of 1:13. The results are also compared with the C stock changes reported by countries to the climate convention (UNFCCC). Our results reveal that the variation in SOC and clay content at European scale exceeds that of the data used to develop the proposed indicator. We also found that the variation in the SOC content was influenced not only by clay content but also by climate and land-use reflecting C input levels. Therefore, the defined threshold is inadequate for detecting degraded soils if the SOC and clay content are beyond the conditions used to establish the criteria. Furthermore, major discrepancies were observed between the soil carbon stock changes reported by the national greenhouse gas (GHG) inventories and the proportions of degraded soils identified by using the soil C loss indicator. We conclude that employing a single indicator such as SOC:Clay ratio with one threshold value for all soils across various land covers, management practices, and climatic conditions, as defined by the European Commission for the Soil Monitoring Law, is inappropriate for monitoring soil C loss.", "keywords": ["2.

However, knowledge of how the long-term presence of grazers affects soil carbon sequestration is limited. In this study, we estimated total accumulated organic carbon in soils of a back-barrier salt marsh and determined how this is affected by long-term grazing by both small and large grazers in relation to age of the ecosystem. In young marshes, where small grazers predominate, hare and geese have a limited effect on total accumulated organic carbon. In older, mature marshes, where large grazers predominate, cattle substantially enhanced carbon content in the marsh soil. We ascribe this to a shift in biomass distribution in the local vegetation towards the roots in combination with trampling effects on the soil chemistry. These large grazers thus act as ecosystem engineers: their known effect on soil compaction (based on a previous study) enhances anoxic conditions in the marsh soil, thereby reducing the oxygen available for organic carbon decomposition by the local microbial community. This study showed that the indirect effects of grazing can significantly enhance soil carbon storage through changing soil abiotic conditions. This process should be taken into account when estimating the role of ecosystems in reducing carbon dioxide concentration in the atmosphere. Ultimately, we propose a testable conceptual framework that includes 3 pathways by which grazers can alter carbon storage: (1) through above-ground biomass removal, (2) through alteration of biomass distribution towards the roots and/or (3) by changing soil abiotic conditions that affect decomposition.</p>", "keywords": ["Carbon sequestration", "0106 biological sciences", "IMPACT", "SEA-LEVEL RISE", "01 natural sciences", "Coastal wetland", "Climate change", "Biology", "Soil compaction", "Succession", "VEGETATION SUCCESSION", "0105 earth and related environmental sciences", "2.

Extreme sensitivity of soil organic carbon (SOC) to climate and land use change warrants further research in different terrestrial ecosystems. The aim of this study was to investigate the link between aggregate and SOC dynamics in a chronosequence of three different land uses of a south Chilean Andisol: a second growth Nothofagus obliqua forest (SGFOR), a grassland (GRASS) and a Pinus radiata plantation (PINUS). Total carbon content of the 0-10cm soil layer was higher for GRASS (6.7 kg C m-2) than for PINUS (4.3 kg C m-2, while TC content of SGFOR (5.8 kg C m-2) was not significantly different from either one. High extractable oxalate and pyrophosphate Al concentrations (varying from 20.3-24.4 g kg-1, and 3.9-11.1 g kg-1, respectively) were found in all sites. In this study, SOC and aggregate dynamics were studied using size and density fractionation experiments of the SOC, \uffce\uffb413C and total carbon analysis of the different SOC fractions, and C mineralization experiments. The results showed that electrostatic sorption between and among amorphous Al components and clay minerals is mainly responsible for the formation of metal-humus-clay complexes and the stabilization of soil aggregates. The process of ligand exchange between SOC and Al would be of minor importance resulting in the absence of aggregate hierarchy in this soil type. Whole soil C mineralization rate constants were highest for SGFOR and PINUS, followed by GRASS (respectively 0.495, 0.266 and 0.196 g CO2-Cm-2d-1 for the top soil layer). In contrast, incubation experiments of isolated macro organic matter fractions gave opposite results, showing that the recalcitrance of the SOC decreased in another order: PINUS&gt;SGFOR&gt;GRASS. We deduced that electrostatic sorption processes and physical protection of SOC in soil aggregates were the main processes determining SOC stabilization. As a result, high aggregate carbon concentrations, varying from 148 till 48 g kg-1, were encountered for all land use sites. Al availability and electrostatic charges are dependent on pH, resulting in an important influence of soil pH on aggregate stability. Recalcitrance of the SOC did not appear to largely affect SOC stabilization. Statistical correlations between extractable amorphous Al contents, aggregate stability and C mineralization rate constants were encountered, supporting this hypothesis. Land use changes affected SOC dynamics and aggregate stability by modifying soil pH (and thus electrostatic charges and available Al content), root SOC input and management practices (such as ploughing and accompanying drying of the soil).                     </p>", "keywords": ["DECOMPOSITION", "NEW-ZEALAND", "DENSITY FRACTIONS", "[SDU.ASTR] Sciences of the Universe [physics]/Astrophysics [astro-ph]", "HUMIC-ACID", "Life", "QH501-531", "QH540-549.5", "2.

We propose an approach in which: (1) we delineate soil units applying unsupervised classification to a set of environmental covariates, proxies of the soil\uffe2\uff80\uff90forming factors (pedogenon mapping) and (2) use semi\uffe2\uff80\uff90natural native forests (i.e., secondary forests of native species with lesser human interventions compared to past decades) as references for setting unit\uffe2\uff80\uff90specific thresholds for soil indicators (reference approach) and (3) assessing and mapping the condition of forest plantations (intensively managed forests). We apply this approach to the Basque Country using soil data from the forest monitoring network Basonet. When considering the threshold suggested by the SML for SOC:clay (&lt;\uffe2\uff80\uff891/13), 61% of plots at 0\uffe2\uff80\uff9320\uffe2\uff80\uff89cm layer and 90% at 20\uffe2\uff80\uff9340\uffe2\uff80\uff89cm layer of plantations were in poor condition (unhealthy), while 37% of plots at 0\uffe2\uff80\uff9320\uffe2\uff80\uff89cm and 79% at 20\uffe2\uff80\uff9340\uffe2\uff80\uff89cm of semi\uffe2\uff80\uff90natural forests would be considered unhealthy. When considering semi\uffe2\uff80\uff90natural forest as references the proportion of plantation plots in poor condition for SOC:clay ranged between 14%\uffe2\uff80\uff9350% depending on the percentile used to set thresholds (5th and 25th percentiles). Forest plantations had lower soil pH compared to semi\uffe2\uff80\uff90natural forests, with 15%\uffe2\uff80\uff9360% of plantation plots with pH lower than the unit\uffe2\uff80\uff90specific thresholds (poor condition). Only 3% of topsoils and 2% of subsoils under plantations were considered unhealthy with a fixed pH threshold of 4.2. All plantation plots were in good condition (healthy) in terms of bulk density with the EU criteria, but 9.6% of semi\uffe2\uff80\uff90natural plots had greater bulk density than the suggested thresholds. Our approach demonstrates the need of considering the context of soil\uffe2\uff80\uff90forming factors when identifying thresholds for soil health indicators.</p", "keywords": ["European soil monitoring law", "Soil health", "Forest soil", "Thresholds", "Soil monitoring unit"], "contacts": [{"organization": "Mercedes Rom\u00e1n Dobarco, Alex B.

There is increasing evidence that fires cause a shift in soil microbial communities, which play a central role in forest carbon and nutrient cycling. In this study, we evaluate the effect of soil heating on soil microbial functions. We hypothesised that fire reduces the catabolic functional diversity of soil, and that post\uffe2\uff80\uff90fire plant growth enhances its recovery. To test this, we experimentally heated a forest soil at 200\uffc2\uffb0C (T200) or 450\uffc2\uffb0C (T450). Heated and unheated soils were then incubated in tubs with or without live grass (                       Lolium perenne                       L.).

Geothermally active areas in Iceland provided wide, continuous and stable gradients of\u00a0soil temperatures\u00a0to test this hypothesis. In order to characterize the stoichiometric demands of microbes from these subarctic soils, we incubated soils from ambient temperatures after the factorial addition of C, N and P substrates separately and in combination. In a second experiment, soils that had been exposed to different\u00a0in situ\u00a0warming intensities (+0, +0.5, +1.8, +3.4, +8.7, +15.9\u00a0\u00b0C above ambient) for seven years were incubated after the combined addition of C, N and P to evaluate the capacity of soil microbes to store and immobilize C and N at the different warming scenarios. The seven years of chronic soil warming triggered large and proportional soil C and N losses (4.1\u00a0\u00b1\u00a00.5% \u00b0C\u22121\u00a0of the stocks in unwarmed soils) from the upper 10\u202fcm of soil, with a predominant depletion of the physically accessible organic substrates that were weakly sorbed in\u00a0soil minerals\u00a0up to 8.7\u202f\u00b0C warming. Soil microbes met the increasing respiratory demands under conditions of low C accessibility at the expenses of a reduction of the standing biomass in warmer soils. This together with the strict microbial C:N stoichiometric demands also constrained their capacity of N retention, and increased the vulnerability of soil to N losses. Our findings suggest a strong control of\u00a0microbial physiology and C:N stoichiometric needs on the retention of soil N and on the resilience of soil C stocks from high-latitudes to warming, particularly during periods of vegetation dormancy and low C inputs.", "keywords": ["0301 basic medicine", "Microbial carbon and nutrients limitation", "Microbial biomass", "TERM", "03 medical and health sciences", "FOREST SOIL", "Temperature increase", "ORGANIC-CARBON", "Substrate induced respiration", "SDG 13 - Climate Action", "TEMPERATURE SENSITIVITY", "CYCLE", "106026 Ecosystem research", "METAANALYSIS", "2.
