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.

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 effects are chiefly a result of burn severity, which consists of peak temperatures and duration of the fire. Climate, vegetation, and topography of the burnt area control the resilience of the soil system; some fire-induced changes can even be permanent. Low to moderate severity fires, such as most of those prescribed in forest management, promote renovation of the dominant vegetation through elimination of undesired species and transient increase of pH and available nutrients. No irreversible ecosystem change occurs, but the enhancement of hydrophobicity can render the soil less able to soak up water and more prone to erosion. Severe fires, such as wildfires, generally have several negative effects on soil. They cause significant removal of organic matter, deterioration of both structure and porosity, considerable loss of nutrients through volatilisation, ash entrapment in smoke columns, leaching and erosion, and marked alteration of both quantity and specific composition of microbial and soil-dwelling invertebrate communities. However, despite common perceptions, if plants succeed in promptly recolonising the burnt area, the pre-fire level of most properties can be recovered and even enhanced.

After application of the same amount of N as urea, alfalfa, rice straw, or compost\u00a0in the organic soils and urea or alfalfa in the conventional soils, water-extractable amino acid composition and concentrations, and inorganic and microbial N were measured during a 56 day soil incubation. 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.

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.

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.

Forest fires can alter the biological properties of soils. 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.). We determined the functional profiles by measuring the substrate\uffe2\uff80\uff90induced respiration (SIR) using the Microresp\uffe2\uff84\uffa2 technique and analysed nutrient availability at the end of the incubation. At both temperatures, soil heating altered the respiration responses to substrate additions and the catabolic functional diversity of soils. Functional diversity was initially reduced in T200 soils but recovered at the end of the incubation. In contrast, T450 soils initially maintained the catabolic functional diversity, but decreased at the end of the incubation. Heating\uffe2\uff80\uff90induced nutrient availability stimulated the growth of grass, which in turn increased the response to several substrates and increased the functional diversity to values similar to the unheated controls. Our results suggest that fire\uffe2\uff80\uff90driven alteration of soil microbial communities has consequences at a functional level, and that the recovery of plant communities enhances the recovery of soil microbial functions.

Highlights

Soil experimental heating altered microbial functions and reduced soil functional diversity.

Soil heating also increased nutrient availability, enhancing plant growth.

Growth of plants promoted the recovery of soil functional diversity.

Post\uffe2\uff80\uff90fire recovery of functional diversity may be related to the recovery of photosynthetic tissues.

&lt;p&gt;Plant litter chemistry is altered during decomposition but it remains unknown if these alterations, and thus the composition of residual litter, will change in response to climate. 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;#948;&lt;sup&gt;13&lt;/sup&gt;C&lt;sub&gt;PLFA&lt;/sub&gt; values as an integrated measure of microbial metabolisms. Changes in litter chemistry and &amp;#948;&lt;sup&gt;13&lt;/sup&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;#948;&lt;sup&gt;13&lt;/sup&gt;C&lt;sub&gt;PLFA&lt;/sub&gt;). Litter in warmer transect regions accumulated less aliphatic&amp;#8208;C (lipids, waxes) and retained more O&amp;#8208;alkyl&amp;#8208;C (carbohydrates), consistent with enhanced &lt;sup&gt;13&lt;/sup&gt;C&amp;#8208;enrichment in residual litter, than in colder regions. These results suggest that chemical changes during litter decomposition will change with climate, driven primarily by indirect climate effects (e.g., greater nitrogen availability and decreased fungi:bacteria ratios) rather than direct temperature effects. A positive correlation between microbial biomass &amp;#948;&lt;sup&gt;13&lt;/sup&gt;C values and &lt;sup&gt;13&lt;/sup&gt;C&amp;#8208;enrichment during decomposition suggests that change in litter chemistry is driven more by distinct microbial necromass inputs than differences in the selective removal of litter components. Our study highlights the role that microbial inputs during early litter decomposition can play in shaping surface litter contribution to soil organic matter as it responds to climate warming effects such as greater nitrogen availability.&lt;/p&gt;

Soil C sequestration may mitigate rising levels of atmospheric CO2. However, it has yet to be determined whether net soil C sequestration occurs in N\uffe2\uff80\uff90rich grasslands exposed to long\uffe2\uff80\uff90term elevated CO2. 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. For the first time, we were able to collect dual\uffe2\uff80\uff90labeled soil samples to a depth of 75\uffe2\uff80\uff83cm after 10 years of elevated CO2 and determine the total amount of new soil C and N sequestered in the whole soil profile. 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. The potential use of fertilized and regular cut pastures as a net soil C sink under long\uffe2\uff80\uff90term elevated CO2 appears to be limited and will likely not significantly contribute to the mitigation of anthropogenic C emissions.

We examine the influence of climate, soil properties and vegetation characteristics on soil organic carbon (SOC) along a transect of West African ecosystems sampled across a precipitation gradient on contrasting soil types stretching from Ghana (15\uffc2\uffb0N) to Mali (7\uffc2\uffb0N). 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>\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.

Abstract. 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 mean measured CH4 flux at the sample points was \uffe2\uff88\uff925.07\uffe2\uff80\uff89\uffc2\uffb5mol\uffe2\uff80\uff89m\uffe2\uff88\uff922\uffe2\uff80\uff89h\uffe2\uff88\uff921 in May\uffe2\uff80\uff93July and \uffe2\uff88\uff928.67\uffe2\uff80\uff89\uffc2\uffb5mol\uffe2\uff80\uff89m\uffe2\uff88\uff922\uffe2\uff80\uff89h\uffe2\uff88\uff921 in August\uffe2\uff80\uff93October, while the modelled flux for the whole area was \uffe2\uff88\uff927.42 and \uffe2\uff88\uff929.91\uffe2\uff80\uff89\uffc2\uffb5mol\uffe2\uff80\uff89m\uffe2\uff88\uff922\uffe2\uff80\uff89h\uffe2\uff88\uff921 for the two seasons, respectively. 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.

D. octaedra enhanced the shoot biomass of the grass Agropyron trachycaulum (Link) Malte (Poaceae) and increased the shoot\uffe2\uff80\uff94to\uffe2\uff80\uff94root ratio during early plant growth. Microbial biomass, basal respiration and respiratory quotient qCO2 in L/F layer material were reduced by D. octaedra but increased in the H layer. The nutrient (NH4+, NO3\uffe2\uff80\uff94, PO43\uffe2\uff80\uff94) content in soil was also affected by D. octaedra but the effects were small. Effects of the earthworms on soil nutrient content were masked by the great variation in the data and by leaching of nutrients from experimental chambers.

Abstract. 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>SGFOR>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).

Forest fires can alter the biological properties of soils. 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.). We determined the functional profiles by measuring the substrate\uffe2\uff80\uff90induced respiration (SIR) using the Microresp\uffe2\uff84\uffa2 technique and analysed nutrient availability at the end of the incubation. At both temperatures, soil heating altered the respiration responses to substrate additions and the catabolic functional diversity of soils. Functional diversity was initially reduced in T200 soils but recovered at the end of the incubation. In contrast, T450 soils initially maintained the catabolic functional diversity, but decreased at the end of the incubation. Heating\uffe2\uff80\uff90induced nutrient availability stimulated the growth of grass, which in turn increased the response to several substrates and increased the functional diversity to values similar to the unheated controls. Our results suggest that fire\uffe2\uff80\uff90driven alteration of soil microbial communities has consequences at a functional level, and that the recovery of plant communities enhances the recovery of soil microbial functions.

Highlights

Soil experimental heating altered microbial functions and reduced soil functional diversity.

Soil heating also increased nutrient availability, enhancing plant growth.

Growth of plants promoted the recovery of soil functional diversity.

Post\uffe2\uff80\uff90fire recovery of functional diversity may be related to the recovery of photosynthetic tissues.

Forest fires can alter the biological properties of soils. 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.). We determined the functional profiles by measuring the substrate\uffe2\uff80\uff90induced respiration (SIR) using the Microresp\uffe2\uff84\uffa2 technique and analysed nutrient availability at the end of the incubation. At both temperatures, soil heating altered the respiration responses to substrate additions and the catabolic functional diversity of soils. Functional diversity was initially reduced in T200 soils but recovered at the end of the incubation. In contrast, T450 soils initially maintained the catabolic functional diversity, but decreased at the end of the incubation. Heating\uffe2\uff80\uff90induced nutrient availability stimulated the growth of grass, which in turn increased the response to several substrates and increased the functional diversity to values similar to the unheated controls. Our results suggest that fire\uffe2\uff80\uff90driven alteration of soil microbial communities has consequences at a functional level, and that the recovery of plant communities enhances the recovery of soil microbial functions.

Highlights

Soil experimental heating altered microbial functions and reduced soil functional diversity.

Soil heating also increased nutrient availability, enhancing plant growth.

Growth of plants promoted the recovery of soil functional diversity.

Post\uffe2\uff80\uff90fire recovery of functional diversity may be related to the recovery of photosynthetic tissues.
