Proper assessment of environmental quality or degradation requires knowledge of how terrestrial C pools respond to land use change. Forest plantations offer a considerable potential to sequester C in aboveground biomass. However, their impact on initial levels of soil organic carbon (SOC) varies from strong losses to gains, possibly affecting C balances in afforestation or reforestation initiatives. We compiled paired\uffe2\uff80\uff90plot studies on how SOC stocks under native vegetation change after planting fast\uffe2\uff80\uff90growth Eucalyptus species in Brazil, where these plantations are becoming increasingly important. SOC changes for the 0\uffe2\uff80\uff9320 and 0\uffe2\uff80\uff9340\uffe2\uff80\uff89cm depths varied between \uffe2\uff88\uff9225 and 42\uffe2\uff80\uff89Mg\uffe2\uff80\uff89ha\uffe2\uff88\uff921, following a normal distribution centered near zero. After replacing native vegetation by Eucalyptus plantations, mean SOC changes were \uffe2\uff88\uff921\uffc2\uffb75 and 0\uffc2\uffb73\uffe2\uff80\uff89Mg\uffe2\uff80\uff89ha\uffe2\uff88\uff921 for the 0\uffe2\uff80\uff9320 and 0\uffe2\uff80\uff9340\uffe2\uff80\uff89cm depths, respectively. These are very low figures in comparison to C stocks usually sequestered in aboveground biomass and were statistically nonsignificant as demonstrated by a t\uffe2\uff80\uff90test at p\uffe2\uff80\uff89<\uffe2\uff80\uff890\uffc2\uffb705. Similar low, nonsignificant SOC changes were estimated after data were stratified into first or second rotation cycles, soil texture and biome (savanna, rainforest or grassland). Although strong SOC losses or gains effectively occurred in some cases, their underpinning causes could not be generally identified in the present work and must be ascribed in a case basis, considering the full set of environmental and management conditions. We conclude that Eucalyptus spp. plantations in average have no net effect on SOC stocks in Brazil. Copyright \uffc2\uffa9 2012 John Wiley & Sons, Ltd.

Attempts to reclaim mangrove swamps for rice growing have shown the importance of a greater knowledge on the effects of land use change on soil properties and soil carbon storage. To address this problem, a study was undertaken within Cacheur and Oio regions in Northern Guinea-Bissau, along the following chronosequence: mangrove, rice and abandoned fields. Changes in C/N ratio, \u03b4 13 C and \u03b4 15 N values were used to study the dynamics of C 3 plant-derived and marine-derived carbon (C) in order to analyze the origin of soil organic matter (SOM) and estimate the impact of marine contribution to SOC. Isotopic signatures within the mangrove swamp rice soils suggested the inwelling of marine derived C. SOC stock was estimated in 0\u201310, 0\u201320, 0\u201340 and 0\u201380\u00a0cm soil layers using fixed soil depth (FD) and fixed soil mass (FM) approaches. The significantly highest values were found in mangrove soils and the lowest in the abandoned fields for both sites, while no significant differences were recorded for the topsoil (0\u201310\u00a0cm) between mangrove and rice fields. The results of this study revealed that conversion of mangrove to rice cropping has technical potential of SOC sequestration in the upper part of the soil (0\u201340\u00a0cm). On the other hand, the abandonment of the fields caused decreases in carbon storage along the whole soil depth.

Measurements at a range of temporal and spatial scales were used to make three different estimates of F NEE based on: (1) the difference between fluxes of carbon input by photosynthesis and output by autotrophic plus heterotrophic respiration, (2) changes over time in the carbon pools in the above- and below-ground biomass, soil and litter, and (3) micrometeorological flux measurements that provide a continuous estimate of the net exchange. A rigorous comparison of aggregated component fluxes and the net eddy fluxes within a flux tower source area was achieved based on an inventory of the site and a detailed sampling strategy. Measurements replicated in space and time provided mean values, confidence limits and patterns of variation of carbon pools and fluxes that allowed comparisons within known limits of uncertainty. As a result of comparisons between nighttime eddy flux and chamber measurements of respiration, a revised micrometeorological method was developed for estimating nighttime carbon flux using flux tower measurements. Uncertainty in the final estimate of F NEE was reduced through mutual constraints of each of these measurement approaches. F NEE for the period October 2001\u2013September 2002, with average rainfall, was an uptake of 6.7 (5.1\u20138.3)\u00a0tC\u00a0ha \u22121 \u00a0yr \u22121 estimated from component fluxes, and 5.4 (3.0\u20137.5)\u00a0tC\u00a0ha \u22121 \u00a0yr \u22121 estimated from the revised eddy flux method.

The sampling effort required to assess SOC and FFC stocks is therefore large, resulting in limited sampling and poor estimates of the size, spatial distribution, and changes in SOC and FFC stocks in many countries. Forest SOC and FFC stocks are influenced by tree species. Therefore, quantification of the effect of tree species on carbon stocks combined with spatial information on tree species distribution could improve insight into the spatial distribution of forest carbon stocks. We present a study on the effect of tree species on FFC and SOC stock for a forest in the Netherlands and evaluate how this information could be used for inventory improvement. We assessed FFC and SOC stocks in stands of beech (Fagus sylvatica), Douglas fir (Pseudotsuga menziesii), Scots pine (Pinus sylvestris), oak (Quercus robur) and larch (Larix kaempferi). FFC and SOC stocks differed between a number of species. FFC stocks varied between 11.1 Mg C ha-1 (beech) and 29.6 Mg C ha-1 (larch). SOC stocks varied between 53.3 Mg C ha-1 (beech) and 97.1 Mg C ha-1 (larch). At managed locations, carbon stocks were lower than at unmanaged locations. The Dutch carbon inventory currently overestimates FFC stocks. Differences in carbon stocks between conifer and broadleaf forests were significant enough to consider them relevant for the Dutch system for carbon inventory.

Unfortunately, optimal sampling of the rangelands for baseline C(s) - the critical first step towards efficient monitoring - has received relatively little attention to date. Moreover, in the rangelands of tropical Australia relatively little is known about how C(s) is influenced by the practice of cattle grazing. To address these issues we used linear mixed models to: (i) unravel how grazing pressure (over a 12-year period) and soil type have affected C(s) and the stable carbon isotope ratio of soil organic carbon (delta(13)C) (a measure of the relative contributions of C(3) and C(4) vegetation to C(s)); (ii) examine the spatial covariation of C(s) and delta(13)C; and, (iii) explore the amount of soil sampling required to adequately determine baseline C(s). Modelling was done in the context of the material coordinate system for the soil profile, therefore the depths reported, while conventional, are only nominal. Linear mixed models revealed that soil type and grazing pressure interacted to influence C(s) to a depth of 0.3 m in the profile. At a depth of 0.5 m there was no effect of grazing on C(s), but the soil type effect on C(s) was significant. Soil type influenced delta(13)C to a soil depth of 0.5 m but there was no effect of grazing at any depth examined. The linear mixed model also revealed the strong negative correlation of C(s) with delta(13)C, particularly to a depth of 0.1 m in the soil profile. This suggested that increased C(s) at the study site was associated with increased input of C from C(3) trees and shrubs relative to the C(4) perennial grasses; as the latter form the bulk of the cattle diet, we contend that C sequestration may be negatively correlated with forage production. Our baseline C(s) sampling recommendation for cattle-grazing properties of the tropical rangelands of Australia is to: (i) divide the property into units of apparently uniform soil type and grazing management; (ii) use stratified simple random sampling to spread at least 25 soil sampling locations about each unit, with at least two samples collected per stratum. This will be adequate to accurately estimate baseline mean C(s) to within 20% of the true mean, to a nominal depth of 0.3 m in the profile.", "keywords": ["2.

Significant greenhouse gas (GHG) emissions can result from land use change due to the expansion and cultivation of soybean. However, this is complex to assess and the results can vary widely. The main goal of this article is to investigate the life-cycle GHG balance for soybean produced in Latin America, assessing the implications of direct land use change emissions and different cultivation systems. A life-cycle model, including inventories for soybean produced in three different climate regions, was developed, addressing land use change, cultivation and transport to Europe. A comprehensive evaluation of alternative land use change scenarios (conversion of tropical forest, forest plantations, perennial crop plantations, savannah and grasslands), cultivation (tillage, reduced tillage and no-tillage) and soybean transportation systems was undertaken. The main results show the importance of land use change in soybean GHG emissions, but significant differences were observed for the alternative scenarios, namely 0.1\u201317.8\u00a0kg\u00a0CO2eq\u00a0kg\u22121 soybean. The original land choice is a critical issue in ensuring the lowest soybean GHG balance and degraded grassland should preferably be used for soybean cultivation. The highest GHG emissions were calculated for tropical moist regions when rainforest is converted into soybean plantations (tillage system). When land use change is not considered, the GHG intensity varies from 0.3 to 0.6\u00a0kg CO2eq\u00a0kg\u22121 soybean.

However, mangroves are disappearing worldwide because of demographic increases. In addition to the loss of CO2 fixation, mangrove clearing can strongly affect soil characteristics and C storage. The objectives of the present study were to quantify the evolution of soil quality, carbon stocks and carbon fluxes after mangrove clearing. Sediment cores to assess physico-chemical properties were collected and in situ CO2 fluxes were measured at the soil-air interface in a mangrove of Northern Vietnam. We compared a Kandelia candel mangrove forest with a nearby zone that had been cleared two years before the study. Significant decrease of clay content and an increase in bulk density for the upper 35cm in the cleared zone were observed. Soil organic carbon (OC) content in the upper 35cm decreased by >65% two years after clearing. The quantity and the quality of the carbon changed, with lower carbon to nitrogen ratios, indicating a more decomposed OM, a higher content of dissolved organic carbon, and a higher content of inorganic carbon (three times higher). This highlights the efficiency of mineralization processes following clearing. Due to the rapid decrease in the soil carbon content, CO2 fluxes at sediment interface were >50% lower in the cleared zone. Taking into account carbonate precipitation after OC mineralization, the mangrove soil lost ~10MgOCha-1yr-1 mostly as CO2 to the atmosphere and possibly as dissolved forms towards adjacent ecosystems. The impacts on the carbon cycle of mangrove clearing as shown by the switch from a C sink to a C source highlight the importance of maintaining these ecosystems, particularly in a context of climate change.", "keywords": ["580", "0106 biological sciences", "2.

In Brazil, significant changes in land use result from the conversion of native vegetation to pasture and agriculture, conversion of pasture to agriculture and, more recently, the conversion of pasture and agriculture to integrated crop-livestock systems (ICL). The ICL system proposes a diversity of activities that include the strategic incorporation of pastures to agriculture so as to benefit both. In agricultural areas, for example, the implementation of ICL requires the production of quality forage for animals between crops as well as the production of straw to facilitate the sustainability of the no-tillage (NT) management system. The objective of this study was to evaluate the modifications in soil C stocks resulting from the main processes involved in the changes of land use in Amazonia and Cerrado biomes. For comparison purposes, areas under native vegetation, pastures, crop succession and ICL under different edapho-climatic conditions in Amazonia and Cerrado biomes were evaluated. This study demonstrated that the conversion of native vegetation to pasture can cause the soil to function either as a source or a sink of atmospheric CO2, depending on the land management applied. Non-degraded pasture under fertile soil showed a mean accumulation rate of 0.46\u00a0g\u00a0ha\u22121\u00a0year\u22121. Carbon losses from pastures implemented in naturally low fertile soil ranged from 0.15 to 1.53\u00a0Mg\u00a0ha\u22121\u00a0year\u22121, respectively, for non-degraded and degraded pasture. The conversion of native vegetation to agriculture in areas under the ICL system, even when cultivated under NT, resulted in C losses of 1.31 in six years and of 0.69\u00a0Mg\u00a0ha\u22121 in 21 years. The conversion of a non-degraded pasture to cropland (soybean/sorghum) released, in average, 1.44 Mg of C ha\u22121year\u22121to the atmosphere. The ICL system in agricultural areas has shown evidences that it always functions as a sink of C with accumulation rates ranging from 0.82 to 2.58\u00a0Mg\u00a0ha\u22121\u00a0year\u22121. The ICL produces soil C accumulation and, as a consequence, reduces atmospheric CO2 in areas formerly cultivated under crop succession. However, the magnitude of C accumulation in soil depends on factors such as the types of crops, the edapho-climatic conditions and the amount of time the area is under ICL.", "keywords": ["[SDV.SA]Life Sciences [q-bio]/Agricultural sciences", "550", "limiting water range", "01 natural sciences", "630", "atlantic forest", "Amazonia", "Crop-livestock systems", "Land use change", "0105 earth and related environmental sciences", "2.

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.

In a long-term experiment (1992-2008) we examined the effects of various tillage intensities: no-tillage (NT), minimum tillage with chisel plow (MT), and conventional tillage with mouldboard plow (CT), on the topsoil profile distribution (0-30cm) of SOC, on a semi-arid loamy soil from Central Spain. The crop sequence established was cheap pea (Cicer arietinun L.) cv. Inmaculada/barley (Hordeum vulgare L.) cv. Volley. Soil organic carbon in the various tillage treatments was expressed on a content bases and the equivalent soil mass approach. Measurements made at the end of 17 years showed that in the 0-30cm depth, stocks of SOC had increased under NT compared with MT and CT. Most dramatic changes occurred within the 0-5cm layer where plots under NT had 5.8 and 7.6Mgha-1 more SOC than under MT or CT respectively. No-tillage plots, however, exhibited strong vertical gradients of SOC with concentrations decreasing from 0-5 to 20-30cm. Stratification ratios of SOC in 1992 showed no significant differences between tillage systems. On the contrary, from 1993 onwards all stratification ratios were significantly higher in NT than in the other two tillage systems. In addition, since 2003 stratification ratios of SOC obtained under NT were systematically >2 and more than 2-fold those obtained under MT and CT. Stratification ratios >2 are uncommon under degraded conditions and could suggest that NT management system may have the most benefits to soil quality in semi arid regions with low native soil organic matter. \u00a9 2010 Elsevier B.V.", "keywords": ["2.

Land use type is a major determining factor that influences soil microbial community composition in floodplain ecosystems. However, how the structure and diversity of soil microbial communities respond to specific changes in land use, as well as the main drivers of these changes, are still unclear. This study was conducted in the Yellow River floodplain to examine the effects of land use type on soil microbial communities. Four land use types (shrubland, farmland, grassland and forest) were selected, wherein shrubland served as the baseline. We measured soil microbial structure and diversity using phospholipid fatty acids (PLFAs). Land use type significantly affected total, bacterial and fungal PLFAs, and the gram-positive/negative bacterial PLFAs. Compared with shrubland, peanut farmland had higher total and bacterial PLFAs and forest had higher fungal PLFAs. Soil pH and phosphorus were the predominate drivers of microbial PLFAs, explaining 37% and 26% of the variability, respectively. Soil total nitrogen and nitrate nitrogen were the main factors increasing microbial community diversity. Peanut farmland had the highest soil carbon content, soil carbon stock, total PLFAs and microbial diversity, suggesting that farmland has great potential as a carbon sink. Our findings indicated that peanut farmland in the Yellow River floodplain is critical for maintaining soil microbial communities and soil carbon sequestration.
Organic farming (OF) enhances top soil organic carbon (SOC) stocks in croplands compared with conventional farming (CF), which can contribute to sequester C. As farming system differences in the amount of C inputs to soil (e.g. fertilization and crop residues) are not enough to explain such increase, shifts in crop residue traits important for soil C losses such as litter decomposition may also play a role.
To assess whether crop residue (leaf and root) traits determined SOC sequestration responses to OF, we coupled a global meta\uffe2\uff80\uff90analysis with field measurements across a European\uffe2\uff80\uff90wide network of sites. In the meta\uffe2\uff80\uff90analysis, we related crop species averages of leaf N, leaf\uffe2\uff80\uff90dry matter content, fine\uffe2\uff80\uff90root C and N, with SOC stocks and sequestration responses in OF vs. CF. Across six European sites, we measured the management\uffe2\uff80\uff90induced changes in SOC stocks and leaf litter traits after long\uffe2\uff80\uff90term ecological intensive (e.g. OF) vs. CF comparisons.
Our global meta\uffe2\uff80\uff90analysis showed that the positive OF\uffe2\uff80\uff90effects on soil respiration, SOC stocks, and SOC sequestration rates were significant even in organic farms with low manure application rates. Although fertilization intensity was the main driver of OF\uffe2\uff80\uff90effects on SOC, leaf and root N concentrations also played a significant role. Across the six European sites, changes towards higher leaf litter N in CF also promoted lower SOC stocks.
Our results highlight that crop species displaying traits indicative of resource\uffe2\uff80\uff90acquisitive strategies (e.g. high leaf and root N) increase the difference in SOC between OF and CF. Indeed, changes towards higher crop residue decomposability was related with decreased SOC stocks under CF across European sites.
Synthesis and applications. Our study emphasizes that, with management, changes in crop residue traits contribute to the positive effects of organic farming (OF) on soil carbon sequestration. These results provide a clear message to land managers: the choice of crop species, and more importantly their functional traits (e.g. leave and root nitrogen), should be considered in addition to management practices and climate, when evaluating the potential of OF for climate change mitigation.

Yet, the magnitude and temporal scale of these impacts are largely unknown. We undertook a systematic review to examine the influence of LULCC on mangrove carbon stocks and soil greenhouse gas (GHG) effluxes. A search of 478 data points from the peer\uffe2\uff80\uff90reviewed literature revealed a substantial reduction of biomass (82%\uffc2\uffa0\uffc2\uffb1\uffc2\uffa035%) and soil (54%\uffc2\uffa0\uffc2\uffb1\uffc2\uffa013%) carbon stocks due to LULCC. The relative loss depended on LULCC type, time since LULCC and geographical and climatic conditions of sites. We also observed that the loss of soil carbon stocks was linked to the decreased soil carbon content and increased soil bulk density over the first 100\uffc2\uffa0cm depth. We found no significant effect of LULCC on soil GHG effluxes. Regeneration efforts (i.e. restoration, rehabilitation and afforestation) led to biomass recovery after ~40\uffc2\uffa0years. However, we found no clear patterns of mangrove soil carbon stock re\uffe2\uff80\uff90establishment following biomass recovery. Our findings suggest that regeneration may help restore carbon stocks back to pre\uffe2\uff80\uff90disturbed levels over decadal to century time scales only, with a faster rate for biomass recovery than for soil carbon stocks. Therefore, improved mangrove ecosystem management by preventing further LULCC and promoting rehabilitation is fundamental for effective climate change mitigation policy.

The objective of this study is to evaluate the effects of cropping systems on the biological attributes of an oxisol in the Amazonian state of Para. The treatments consisted of approximately 20-year-old secondary vegetation, recovered pasture, no-tillage systems (NT) maintained for 4 and 8 years after planting with corn (Zea mays L.) and soybean (Glycine max L.), and conventional tillage (CT) systems every 2 years after planting with rice (Oryza sativa L.) and soybean. The microbial biomass to nitrogen ratio was higher in the NT system (0.68 mg kg\u20131), and the NT system had greater microbial NT8. Thus, the contributions of organic matter from straw improved the soil quality in these areas. The total organic carbon (TOC) content was greater in the secondary forest and CT areas (46.7 and 48.0 mg kg\u20131, respectively), potentially due to the higher amounts of organic matter and organic matter mineralization in these areas. However, the largest TOC stocks were observed in the pasture, which corresponded with greater carbon storage (63.5 Mg ha\u20131). By contrast, the no-till systems were not efficient for storing C, with concentrations of 5.0 and 5.3 Mg ha\u20131 in NT-4 and NT-8, respectively.

Soil samples were collected in areas of native forest (NF), of 8 to 10 year old secondary forest (SF), 1 to 2 year old SF (P1-2), 5 to 7 year old SF (P5-7), and of 10 to 12 year old SF (P10-12), and from under pastures, in the layers 0-2, 2-5 and 5-10 cm, to evaluate C levels and stocks and carry out separation of OM based on particle size. After deforestation, soil density increased to a depth of 5 cm, with greater increase in older pastures. Variation in C levels was greatest in the top soil layer; C contents increased with increasing pasture age. In the layers 2-5 and 5-10 cm, C content proved to be stable for the types of plant cover evaluated. Highest C concentrations were found in the silt fraction; however, C contents were highest in the clay fraction, independent of the plant cover. An increase in C associated with the sand fraction in the form of little decomposed organic residues was observed in pastures, confirming greater sensitivity of this fraction to change in soil use.

Understanding how soil pools of these two elements change in response to disturbance and management is critical to maintaining ecosystem services such as forest productivity, greenhouse gas mitigation, and water resource protection. Fire is one of the principal disturbances acting on forest soil C and N storage and is also the subject of enormous management efforts. In the present article, we use meta-analysis to quantify fire effects on temperate forest soil C and N storage. Across a combined total of 468 soil C and N response ratios from 57 publications (concentrations and pool sizes), fire had significant overall effects on soil C (-26%) and soil N (-22%). The impacts of fire on forest floors were significantly different from its effects on mineral soils. Fires reduced forest floor C and N storage (pool sizes only) by an average of 59% and 50%, respectively, but the concentrations of these two elements did not change. Prescribed fires caused smaller reductions in forest floor C and N storage (-46% and -35%) than wildfires (-67% and -69%), and the presence of hardwoods also mitigated fire impacts. Burned forest floors recovered their C and N pools in an average of 128 and 103 years, respectively. Among mineral soils, there were no significant changes in C or N storage, but C and N concentrations declined significantly (-11% and -12%, respectively). Mineral soil C and N concentrations were significantly affected by fire type, with no change following prescribed burns, but significant reductions in response to wildfires. Geographic variation in fire effects on mineral soil C and N storage underscores the need for region-specific fire management plans, and the role of fire type in mediating C and N shifts (especially in the forest floor) indicates that averting wildfires through prescribed burning is desirable from a soils perspective.", "keywords": ["0106 biological sciences", "Nitrogen", "Science", "soil nitrogen", "Ecology and Evolutionary Biology", "forest management", "04 agricultural and veterinary sciences", "15.

We established 18 10-m radius plots, each containing a pair of 1-m radius subplots (n =36), evenly arrayed across three forest stands that contained areas of both high AM and high EcM tree relative basal area as well as a patchy distribution of the ErM shrub Kalmia latifolia.\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\u00a0 \u00a0 Within each of the 18 plots, we established paired 1-m radius subplots with and without K. latifolia in the understory ( \u201c+/- ErM subplot\u201d) within 2 m of the center of the 10-m radius plot. In each 1-m radius subplot, we measured trees \u22651 cm diameter at breast height (DBH; 1.37 m). We also measured DBH of all trees \u226520 cm DBH within 10 m and trees \u22655 cm DBH within 5 m of plot center. We calculated the percentage of EcM tree basal area out of total basal area, scaled to m2 ha-1. \u00a0 In June 2021, we collected and pooled two soil samples for each of three depths within the 36 paired subplots (i.e. 18 +ErM and 18 -ErM subplots). The three depths included: (1) the Oa horizon (depth varied depending on the thickness of the horizon); (2) the top 10 cm of the A horizon, beginning at the base of the Oa horizon; and (3) a second, contiguous A horizon sample that reached a cumulative sampling depth of 30 cm, inclusive of the depth of the Oa horizon. For the organic layer, we removed the litter layer (i.e. the Oi and Oe horizons) and collected and pooled two 25 by 25-cm areas of the Oa horizon using a square template. For the mineral layers, we collected two contiguous depth increments from the A horizon within the footprint of the 25 by 25-cm areas using a 5.08-cm diameter hammer corer. In each instance, we recorded the exact sampling depth. Two subplots did not have an Oa horizon, so we collected a total of 106 samples (3 sites \u00d7 6 plots \u00d7 2 subplots \u00d7 3 depths \u2212 2 Oa samples). Soils were stored at 4\u00b0C prior to their analysis. \u00a0 To prepare the soil samples for analysis, we weighed and homogenized each sample, air dried a representative subsample of non-sieved soil, and passed the remaining field-moist sample through a 4-mm sieve. Using the non-sieved subsample, we estimated the mass and volume of roots and stones and calculated soil bulk density values. For total soil organic matter (SOM) content, we heated samples at 550\u00b0C for 12-h in a muffle furnace and calculated loss on ignition. \u00a0 We used a modified substrate-induced respiration method as an indicator of active saprotrophic microbial biomass. Using autolyzed yeast extract solution as a labile C substrate, we measured rates of CO2 efflux over a 4-h incubation period with an Infra-Red Gas Analyzer and calculated the rate of C-CO2 production per unit of equivalent soil dry mass. For microbially-available C, we estimated potential CO2 production rates over a 14-d incubation period. We measured CO2 efflux over 24-h periods at days 1, 5, 8, and 14 and integrated the four measurements to calculate cumulative C-CO2 production. We estimated water holding capacity by saturating each field-moist sample with water and allowing it to drain freely for 2 h. To calculate the equivalent dry mass of field-moist samples, we measured gravimetric water content by oven-drying the samples to constant mass at 105\u00b0C. \u00a0 We separated the >53 and <53\u2009\u00b5m particle size fractions to quantify particulate (POM) and mineral-associated soil organic matter fractions. We passed air-dried samples through a 2-mm sieve and then dispersed soil aggregates by shaking ~30 g of the sieved, air-dried sample with 30\u2009mL of sodium hexametaphosphate (NaHMP) solution for 18 h. We rinsed each sample over a 53-\u00b5m sieve with deionized water until the water passing through the sieve ran clear. We oven-dried the >53-\u00b5m fraction retained on the top of the sieve and a representative subsample of the <53-\u00b5m fraction suspended in solution at 70\u00b0C. To estimate the mass of the <53-\u00b5m fraction, we calculated the difference between the initial soil mass (105\u00b0C equivalent) and the recovered mass of the >53-\u00b5m fraction (105\u00b0C equivalent). To convert air-dried soil mass to oven-dried mass we dried a subsample of each air-dried sample at 105\u00b0C. Fractions were ground to a fine powder and analyzed for total carbon (C) and nitrogen (N) concentrations using a Costech ESC 4010 Elemental Analyzer. \u00a0 We used an equivalent soil mass approach to calculate soil C, N, SOM, microbial biomass, and microbially-available C stocks in three equivalent soil mass layers as well as the sum of the three layers to estimate cumulative stocks at the subplot level. Following this approach, we report stocks to a standard soil mass and therefore allow the depth of the equivalent soil mass layers to vary depending on soil bulk density. To calculate equivalent soil mass stocks, we added or subtracted elemental stocks of the deeper soil layer to the upper soil layer in 1-mm increments until the soil mass from the upper layer is closest to that of the target soil mass. We chose reference soil masses using the median or target field sampling depth and the mean bulk density value for each of the three depth increments to make them roughly equivalent to the sampled depths. Based on this method, the organic layer had an equivalent mass of ~2.5 kg soil m-2 (median Oa depth = 2.5 cm; mean Oa bulk density = 0.10 g cm-3), the surface mineral layer had an equivalent mass of ~37 kg soil m-2 (target sampling depth = 10 cm; mean bulk density = 0.37 g cm-3), and the subsurface mineral layer had an equivalent mass of ~126 kg soil m-2 (the target sampling depth was 17.5 cm for a sample with a 2.5 cm Oa depth; mean bulk density = 0.72 g cm-3). The cumulative equivalent soil mass for the subplot-level stocks was the sum of the three layers, or ~166 kg soil m-2.", "keywords": ["equivalent soil mass", "ericoid mycorrhizal fungi", "13.

Large herbivores can control plant community composition and, under certain conditions, even induce vegetation shifts to alternative ecosystem states. As different plant assemblages maintain contrasting carbon (C) cycling patterns, herbivores have the potential to alter C sequestration at regional scales. Their influence is of particular interest in the Arctic tundra, where a large share of the world\u2019s soil C reservoir is stored. 2. We analysed how grazing mammals influence tundra vegetation and how grazer-induced vegetation shifts affect tundra C stocks, by resampling two sites located along pasture rotation fences in northern Norway. These fences have separated lightly grazed areas from heavily grazed areas (in close proximity to the fences) and moderately grazed areas (further away from the fences) for the past 50 years. 14 years earlier, the lightly and moderately grazed areas were dominated by dwarf shrubs, whereas heavy grazing had promoted the establishment of graminoid-dominated vegetation. Since then, both reindeer densities and temperatures have increased, and more time has passed for transient dynamics to be expressed. We expected that the vegetation and C stocks would have changed under all grazing intensities, but not necessarily in the same way. 3. At the site where relative reindeer numbers and trampling intensity had increased the most, graminoid-dominated vegetation was now also found in the moderately grazed area. At the other site, the dominant vegetation types under all grazing intensities were the same as 14 years earlier. 4. We show that the heavily grazed, graminoid-dominated, areas stored less C aboveground than the lightly grazed, shrub-dominated, areas. Yet, the belowground consequences of grazing-induced grassification varied between the sites: Grazing did not alter organic soil C stocks at the site where both evergreen and deciduous shrubs were abundant in the lightly grazed area, whereas heavy grazing increased organic soil C stocks at the site where the deciduous shrub Betula nana was dominant. 5. Our results indicate that despite the negative impacts of grazers on aboveground C storage, their impact on belowground C may even be positive. We suggest that the site-specific responses of organic soil C stocks to grazing could be explained by the differences in vegetation under light grazing. This would imply that the replacement of deciduous shrubs by graminoids, as a consequence of grazing, could be beneficial for C sequestration in tundra soils.", "keywords": ["carbon stocks", "Plant functional types", "13.

The rationale was that the corresponding change in temperature (14\u00b0C to 26\u00b0C) would influence tree growth and decomposition of organic matter.

Partial cutting, which removes some individual trees from a forest, is one of the major and widespread forest management practices that can significantly alter both forest structure and carbon (C) storage. Using 746 observations from 82 publications, we synthesized the impacts of partial cutting on three variables associated with forest structure (i.e. mean annual growth of diameter at breast height (DBH), basal area (BA), and volume) and four variables related to various C stock components (i.e. aboveground biomass C (AGBC), understory C, forest floor C, and mineral soil C). Results shows that the growth of DBH elevated by 112% after partial cutting, compared to the uncut control, while stand BA and volume reduced immediately by 34% and 29%, respectively. On average, partial cutting reduced AGBC by 43%, increased understory C storage by 392%, but did not show significant effects on C storages on forest floor and in mineral soil. All the effects on DBH growth, stand BA, volume, and AGBC intensified linearly with cutting intensity (CI) and decreased linearly with the number of recovery years (RY). In addition to the strong impacts of CI and RY, other factors such as climate zone and forest type also affected forest responses to partial cutting. The data assembled in this synthesis were not sufficient to determine how long it would take for a complete recovery after cutting because long-term experiments were rare. Future efforts should be tailored to increase the duration of the experiments and balance geographic locations of field studies.

Predictions had modest temporal variation, with an average decrease for the entire country from 2.55 to 2.48\uffe2\uff80\uff89kg\uffe2\uff80\uff89C\uffe2\uff80\uff89m \uffe2\uff88\uff922 over the 36\uffe2\uff80\uff90year period (equivalent to a decline of 211 Gg C, 3.0% of the total 0\uffe2\uff80\uff9330\uffe2\uff80\uff89cm SOC stock in Argentina). The Pampa region had a larger estimated SOC stock decrease from 4.62 to 4.34\uffe2\uff80\uff89kg\uffe2\uff80\uff89C\uffe2\uff80\uff89m \uffe2\uff88\uff922 (5.9%) during the same period. For the 2001\uffe2\uff80\uff932015 period, predicted temporal variation was seven\uffe2\uff80\uff90fold larger than that obtained using the Tier 1 approach of the Intergovernmental Panel on Climate Change and United Nations Convention to Combat Desertification. Prediction uncertainties turned out to be substantial, mainly due to the limited number and poor spatial and temporal distribution of the calibration data, and the limited explanatory power of the covariates. Cross\uffe2\uff80\uff90validation confirmed that SOC stock prediction accuracy was limited, with a mean error of 0.03\uffe2\uff80\uff89kg\uffe2\uff80\uff89C\uffe2\uff80\uff89m \uffe2\uff88\uff922 and a root mean squared error of 2.04\uffe2\uff80\uff89kg\uffe2\uff80\uff89C\uffe2\uff80\uff89m \uffe2\uff88\uff922 . In spite of the large uncertainties, this work showed that machine learning methods can be used for space\uffe2\uff80\uff93time SOC mapping and may yield valuable information to land managers and policymakers, provided that SOC observation density in space and time is sufficiently large.
Highlights
We tested the use of machine learning for space\uffe2\uff80\uff93time mapping of soil organic carbon (SOC) stock.
Predictions for Argentina from 1982 to 2017 showed a 3% decrease of the topsoil SOC stock over time.
The machine learning model predicted a greater temporal variation than the IPCC Tier 1 approach.
Accurate machine learning SOC stock prediction requires dense soil sampling in space and time.

This substantial amount of C in Arctic and Boreal peatlands is potentially subject to increased decomposition if the water table (WT) decreases due to climate change, including permafrost thaw\uffe2\uff80\uff90related drying. Here, we optimize a version of the Organizing Carbon and Hydrology In Dynamic Ecosystems model (ORCHIDEE\uffe2\uff80\uff90PCH4) using site\uffe2\uff80\uff90specific observations to investigate changes in CO2 and CH4 fluxes as well as C stock responses to an experimentally manipulated decrease of WT at six northern peatlands. The unmanipulated control peatlands, with the WT <20\uffe2\uff80\uff89cm on average (seasonal max up to 45\uffe2\uff80\uff89cm) below the surface, currently act as C sinks in most years (58\uffe2\uff80\uff89\uffc2\uffb1\uffe2\uff80\uff8934\uffe2\uff80\uff89g C\uffe2\uff80\uff89m\uffe2\uff88\uff922\uffc2\uffa0year\uffe2\uff88\uff921; including 6\uffe2\uff80\uff89\uffc2\uffb1\uffe2\uff80\uff897\uffe2\uff80\uff89g C\uffe2\uff80\uff93CH4 m\uffe2\uff88\uff922\uffc2\uffa0year\uffe2\uff88\uff921 emission). We found, however, that lowering the WT by 10\uffe2\uff80\uff89cm reduced the CO2 sink by 13\uffe2\uff80\uff89\uffc2\uffb1\uffe2\uff80\uff8915\uffe2\uff80\uff89g\uffe2\uff80\uff89C\uffe2\uff80\uff89m\uffe2\uff88\uff922\uffc2\uffa0year\uffe2\uff88\uff921 and decreased CH4 emission by 4\uffe2\uff80\uff89\uffc2\uffb1\uffe2\uff80\uff894\uffe2\uff80\uff89g CH4 m\uffe2\uff88\uff922\uffc2\uffa0year\uffe2\uff88\uff921, thus accumulating less C over 100\uffe2\uff80\uff89years (0.2\uffe2\uff80\uff89\uffc2\uffb1\uffe2\uff80\uff890.2\uffe2\uff80\uff89kg\uffe2\uff80\uff89C\uffe2\uff80\uff89m\uffe2\uff88\uff922). Yet, the reduced emission of CH4, which has a larger greenhouse warming potential, resulted in a net decrease in greenhouse gas balance by 310\uffe2\uff80\uff89\uffc2\uffb1\uffe2\uff80\uff89360\uffe2\uff80\uff89g\uffe2\uff80\uff89CO2\uffe2\uff80\uff90eq\uffc2\uffa0m\uffe2\uff88\uff922\uffc2\uffa0year\uffe2\uff88\uff921.

These results highlight that reductions in C storage capacity in response to drying of northern peatlands are offset in part by reduced CH4 emissions, thus slightly reducing the positive carbon climate feedbacks of peatlands under a warmer and drier future climate scenario.Permafrost thaw will release additional carbon dioxide into the atmosphere resulting in a positive feedback to climate change. However, the mineralization dynamics of organic matter (OM) stored in permafrost-affected soils remain unclear. We used physical soil fractionation, radiocarbon measurements, incubation experiments, and a dynamic decomposition model to identify distinct vertical pattern in OM decomposability. The observed differences reflect the type of OM input to the subsoil, either by cryoturbation or otherwise, e.g. by advective water-borne transport of dissolved OM. In non-cryoturbated subsoil horizons, most OM is stabilized at mineral surfaces or by occlusion in aggregates. In contrast, pockets of OM-rich cryoturbated soil contain sufficient free particulate OM for microbial decomposition. After thaw, OM turnover is as fast as in the upper active layer. Since cryoturbated soils store ca. 450 Pg carbon, identifying differences in decomposability according to such translocation processes has large implications for the future global carbon cycle and climate, and directs further process model development.
