Climate\uffe2\uff80\uff90smart agriculture (CSA) management practices (e.g., conservation tillage, cover crops, and biochar applications) have been widely adopted to enhance soil organic carbon (SOC) sequestration and to reduce greenhouse gas emissions while ensuring crop productivity. However, current measurements regarding the influences of CSA management practices on SOC sequestration diverge widely, making it difficult to derive conclusions about individual and combined CSA management effects and bringing large uncertainties in quantifying the potential of the agricultural sector to mitigate climate change. We conducted a meta\uffe2\uff80\uff90analysis of 3,049 paired measurements from 417 peer\uffe2\uff80\uff90reviewed articles to examine the effects of three common CSA management practices on SOC sequestration as well as the environmental controlling factors. We found that, on average, biochar applications represented the most effective approach for increasing SOC content (39%), followed by cover crops (6%) and conservation tillage (5%). Further analysis suggested that the effects of CSA management practices were more pronounced in areas with relatively warmer climates or lower nitrogen fertilizer inputs. Our meta\uffe2\uff80\uff90analysis demonstrated that, through adopting CSA practices, cropland could be an improved carbon sink. We also highlight the importance of considering local environmental factors (e.g., climate and soil conditions and their combination with other management practices) in identifying appropriate CSA practices for mitigating greenhouse gas emissions while ensuring crop productivity.

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.

It quantifies the effect of change from annual to perennial crops and the subsequent temporal changes in SOC stocks during the perennial crop cycle. It also presents an empirical model to estimate changes in the SOC content under crops as a function of time, land use, and site characteristics. We used a harmonized global dataset containing paired\uffe2\uff80\uff90comparison empirical values of SOC and different types of perennial crops (perennial grasses, palms, and woody plants) with different end uses: bioenergy, food, other bio\uffe2\uff80\uff90products, and short rotation coppice. Salient outcomes include: a 20\uffe2\uff80\uff90year period encompassing a change from annual to perennial crops led to an average 20% increase in SOC at 0\uffe2\uff80\uff9330\uffc2\uffa0cm (6.0\uffc2\uffa0\uffc2\uffb1\uffc2\uffa04.6\uffc2\uffa0Mg/ha gain) and a total 10% increase over the 0\uffe2\uff80\uff93100\uffc2\uffa0cm soil profile (5.7\uffc2\uffa0\uffc2\uffb1\uffc2\uffa010.9\uffc2\uffa0Mg/ha). A change from natural pasture to perennial crop decreased SOC stocks by 1% over 0\uffe2\uff80\uff9330\uffc2\uffa0cm (\uffe2\uff88\uff922.5\uffc2\uffa0\uffc2\uffb1\uffc2\uffa04.2\uffc2\uffa0Mg/ha) and 10% over 0\uffe2\uff80\uff93100\uffc2\uffa0cm (\uffe2\uff88\uff9213.6\uffc2\uffa0\uffc2\uffb1\uffc2\uffa08.9\uffc2\uffa0Mg/ha). The effect of a land use change from forest to perennial crops did not show significant impacts, probably due to the limited number of plots; but the data indicated that while a 2% increase in SOC was observed at 0\uffe2\uff80\uff9330\uffc2\uffa0cm (16.81\uffc2\uffa0\uffc2\uffb1\uffc2\uffa055.1\uffc2\uffa0Mg/ha), a decrease in 24% was observed at 30\uffe2\uff80\uff93100\uffc2\uffa0cm (\uffe2\uff88\uff9240.1\uffc2\uffa0\uffc2\uffb1\uffc2\uffa016.8\uffc2\uffa0Mg/ha). Perennial crops generally accumulate SOC through time, especially woody crops; and temperature was the main driver explaining differences in SOC dynamics, followed by crop age, soil bulk density, clay content, and depth. We present empirical evidence showing that the FAO perennialization strategy is reasonable, underscoring the role of perennial crops as a useful component of climate change mitigation strategies.There is a clear need for transformative change in the land management and food production sectors to address the global land challenges of climate change mitigation, climate change adaptation, combatting land degradation and desertification, and delivering food security (referred to hereafter as \uffe2\uff80\uff9cland challenges\uffe2\uff80\uff9d). We assess the potential for 40 practices to address these land challenges and find that: Nine options deliver medium to large benefits for all four land challenges. A further two options have no global estimates for adaptation, but have medium to large benefits for all other land challenges. Five options have large mitigation potential (>3\uffc2\uffa0Gt CO2eq/year) without adverse impacts on the other land challenges. Five options have moderate mitigation potential, with no adverse impacts on the other land challenges. Sixteen practices have large adaptation potential (>25 million people benefit), without adverse side effects on other land challenges. Most practices can be applied without competing for available land. However, seven options could result in competition for land. A large number of practices do not require dedicated land, including several land management options, all value chain options, and all risk management options. Four options could greatly increase competition for land if applied at a large scale, though the impact is scale and context specific, highlighting the need for safeguards to ensure that expansion of land for mitigation does not impact natural systems and food security. A number of practices, such as increased food productivity, dietary change and reduced food loss and waste, can reduce demand for land conversion, thereby potentially freeing\uffe2\uff80\uff90up land and creating opportunities for enhanced implementation of other practices, making them important components of portfolios of practices to address the combined land challenges.There is growing international interest in better managing soils to increase soil organic carbon (SOC) content to contribute to climate change mitigation, to enhance resilience to climate change and to underpin food security, through initiatives such as international \uffe2\uff80\uff984p1000\uffe2\uff80\uff99 initiative and the FAO's Global assessment of SOC sequestration potential (GSOCseq) programme. Since SOC content of soils cannot be easily measured, a key barrier to implementing programmes to increase SOC at large scale, is the need for credible and reliable measurement/monitoring, reporting and verification (MRV) platforms, both for national reporting and for emissions trading. Without such platforms, investments could be considered risky. In this paper, we review methods and challenges of measuring SOC change directly in soils, before examining some recent novel developments that show promise for quantifying SOC. We describe how repeat soil surveys are used to estimate changes in SOC over time, and how long\uffe2\uff80\uff90term experiments and space\uffe2\uff80\uff90for\uffe2\uff80\uff90time substitution sites can serve as sources of knowledge and can be used to test models, and as potential benchmark sites in global frameworks to estimate SOC change. We briefly consider models that can be used to simulate and project change in SOC and examine the MRV platforms for SOC change already in use in various countries/regions. In the final section, we bring together the various components described in this review, to describe a new vision for a global framework for MRV of SOC change, to support national and international initiatives seeking to effect change in the way we manage our soils.Simulation models represent soil organic carbon (SOC) dynamics in global carbon (C) cycle scenarios to support climate\uffe2\uff80\uff90change studies. It is imperative to increase confidence in long\uffe2\uff80\uff90term predictions of SOC dynamics by reducing the uncertainty in model estimates. We evaluated SOC simulated from an ensemble of 26 process\uffe2\uff80\uff90based C models by comparing simulations to experimental data from seven long\uffe2\uff80\uff90term bare\uffe2\uff80\uff90fallow (vegetation\uffe2\uff80\uff90free) plots at six sites: Denmark (two sites), France, Russia, Sweden and the United Kingdom. The decay of SOC in these plots has been monitored for decades since the last inputs of plant material, providing the opportunity to test decomposition without the continuous input of new organic material. The models were run independently over multi\uffe2\uff80\uff90year simulation periods (from 28 to 80\uffc2\uffa0years) in a blind test with no calibration (Bln) and with the following three calibration scenarios, each providing different levels of information and/or allowing different levels of model fitting: (a) calibrating decomposition parameters separately at each experimental site (Spe); (b) using a generic, knowledge\uffe2\uff80\uff90based, parameterization applicable in the Central European region (Gen); and (c) using a combination of both (a) and (b) strategies (Mix). We addressed uncertainties from different modelling approaches with or without spin\uffe2\uff80\uff90up initialization of SOC. Changes in the multi\uffe2\uff80\uff90model median (MMM) of SOC were used as descriptors of the ensemble performance. On average across sites, Gen proved adequate in describing changes in SOC, with MMM equal to average SOC (and standard deviation) of 39.2 (\uffc2\uffb115.5)\uffc2\uffa0Mg\uffc2\uffa0C/ha compared to the observed mean of 36.0 (\uffc2\uffb119.7)\uffc2\uffa0Mg\uffc2\uffa0C/ha (last observed year), indicating sufficiently reliable SOC estimates. Moving to Mix (37.5\uffc2\uffa0\uffc2\uffb1\uffc2\uffa016.7\uffc2\uffa0Mg\uffc2\uffa0C/ha) and Spe (36.8\uffc2\uffa0\uffc2\uffb1\uffc2\uffa019.8\uffc2\uffa0Mg\uffc2\uffa0C/ha) provided only marginal gains in accuracy, but modellers would need to apply more knowledge and a greater calibration effort than in Gen, thereby limiting the wider applicability of models.

However, the mechanisms underlying changes in soil C storage are not well understood, hampering long\uffe2\uff80\uff90term predictions of climate C\uffe2\uff80\uff90feedbacks. The activity of the extracellular enzymes ligninase and cellulase can be used to track changes in the predominant C sources of soil microbes and can thus provide mechanistic insights into soil C loss pathways. Here we show, using meta\uffe2\uff80\uff90analysis, that reductions in soil C stocks with warming are associated with increased ratios of ligninase to cellulase activity. Furthermore, whereas long\uffe2\uff80\uff90term (\uffe2\uff89\uffa55\uffc2\uffa0years) warming reduced the soil recalcitrant C pool by 14%, short\uffe2\uff80\uff90term warming had no significant effect. Together, these results suggest that warming stimulates microbial utilization of recalcitrant C pools, possibly exacerbating long\uffe2\uff80\uff90term climate\uffe2\uff80\uff90C feedbacks.Increased human\uffe2\uff80\uff90derived nitrogen (N) deposition to terrestrial ecosystems has resulted in widespread phosphorus (P) limitation of net primary productivity. However, it remains unclear if and how N\uffe2\uff80\uff90induced P limitation varies over time.

Here we show, using a meta\uffe2\uff80\uff90analysis of 140 studies and 668 observations worldwide, that N stimulation of soil phosphatase activity diminishes over time. Whereas short\uffe2\uff80\uff90term N loading (\uffe2\uff89\uffa45\uffc2\uffa0years) significantly increased soil phosphatase activity by 28%, long\uffe2\uff80\uff90term N loading had no significant effect. Nitrogen loading did not affect soil available P and total P content in either short\uffe2\uff80\uff90 or long\uffe2\uff80\uff90term studies. Together, these results suggest that N\uffe2\uff80\uff90induced P limitation in ecosystems is alleviated in the long\uffe2\uff80\uff90term through the initial stimulation of soil phosphatase activity, thereby securing P supply to support plant growth. Our results suggest that increases in terrestrial carbon uptake due to ongoing anthropogenic N loading may be greater than previously thought.<p>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 &#948;<sup>13</sup>C<sub>PLFA</sub> values as an integrated measure of microbial metabolisms. Changes in litter chemistry and &#948;<sup>13</sup>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 &#948;<sup>13</sup>C<sub>PLFA</sub>). Litter in warmer transect regions accumulated less aliphatic&#8208;C (lipids, waxes) and retained more O&#8208;alkyl&#8208;C (carbohydrates), consistent with enhanced <sup>13</sup>C&#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 &#948;<sup>13</sup>C values and <sup>13</sup>C&#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.</p>

Measurements of DOC concentrations in soil, runoff and drainage are scarce and their spatial distribution highly skewed towards industrialized countries. The contribution of terrestrial DOC leaching to the global\uffe2\uff80\uff90scale C balance of terrestrial ecosystems thus remains poorly constrained. Here, using a process based, integrative, modelling approach to upscale from existing observations, we estimate a global terrestrial DOC leaching flux of 0.28\uffc2\uffa0\uffc2\uffb1\uffc2\uffa00.07\uffc2\uffa0Gt\uffc2\uffa0C\uffc2\uffa0year\uffe2\uff88\uff921 which is conservative, as it only includes the contribution of mineral soils. Our results suggest that globally about 15% of the terrestrial Net Ecosystem Productivity (NEP, calculated as the difference between Net Primary Production and soil respiration) is exported to aquatic systems as leached DOC. In the tropical rainforest, the leached fraction of terrestrial NEP even reaches 22%. Furthermore, we simulated spatial\uffe2\uff80\uff90temporal trends in DOC leaching from soil to the river networks from 1860 to 2010.

Despite their low global contribution to the DOC leaching flux, boreal regions have the highest relative increase (28%) while tropics have the lowest relative increase (9%) over the historical period (1860s compared to 2000s). The results from our observationally constrained model approach demonstrate that DOC leaching is a significant flux in the terrestrial C budget at regional and global scales.The role of soils in the global carbon cycle and in reducing GHG emissions from agriculture has been increasingly acknowledged. The \uffe2\uff80\uff984 per 1000\uffe2\uff80\uff99 (4p1000) initiative has become a prominent action plan for climate change mitigation and achieve food security through an annual increase in soil organic carbon (SOC) stocks by 0.4%, (i.e. 4\uffe2\uff80\uffb0 per year). However, the feasibility of the 4p1000 scenario and, more generally, the capacity of individual countries to implement soil carbon sequestration (SCS) measures remain highly uncertain. Here, we evaluated country\uffe2\uff80\uff90specific SCS potentials of agricultural land for 24 countries in Europe. Based on a detailed survey of available literature, we estimate that between 0.1% and 27% of the agricultural greenhouse gas (GHG) emissions can potentially be compensated by SCS annually within the next decades. Measures varied widely across countries, indicating differences in country\uffe2\uff80\uff90specific environmental conditions and agricultural practices. None of the countries' SCS potential reached the aspirational goal of the 4p1000 initiative, suggesting that in order to achieve this goal, a wider range of measures and implementation pathways need to be explored. Yet, SCS potentials exceeded those from previous pan\uffe2\uff80\uff90European modelling scenarios, underpinning the general need to include national/regional knowledge and expertise to improve estimates of SCS potentials. The complexity of the chosen SCS measurement approaches between countries ranked from tier 1 to tier 3 and included the effect of different controlling factors, suggesting that methodological improvements and standardization of SCS accounting are urgently required. Standardization should include the assessment of key controlling factors such as realistic areas, technical and practical feasibility, trade\uffe2\uff80\uff90offs with other GHG and climate change. Our analysis suggests that country\uffe2\uff80\uff90specific knowledge and SCS estimates together with improved data sharing and harmonization are crucial to better quantify the role of soils in offsetting anthropogenic GHG emissions at global level.

At the same time, arctic grazers are known to prevent the establishment of deciduous shrubs and, under certain conditions, promote the dominance of evergreen shrubs. As these different vegetation types associate with contrasting fungal communities, the belowground consequences of climate change could vary among grazing regimes. Yet, at present, the impact of grazing on soil fungal communities and their links to soil carbon have remained speculative. Here we tested how soil fungal community composition, diversity and function depend on tree vicinity and long\uffe2\uff80\uff90term reindeer grazing regime and assessed how the fungal communities relate to organic soil carbon stocks in an alpine treeline ecotone in Northern Scandinavia. We determined soil carbon stocks and characterized soil fungal communities directly underneath and >3\uffc2\uffa0m away from mountain birches (Betula pubescens ssp. czerepanovii) in two adjacent 55\uffe2\uff80\uff90year\uffe2\uff80\uff90old grazing regimes with or without summer grazing by reindeer (Rangifer tarandus). We show that the area exposed to year\uffe2\uff80\uff90round grazing dominated by evergreen dwarf shrubs had higher soil C:N ratio, higher fungal abundance and lower fungal diversity compared with the area with only winter grazing and higher abundance of mountain birch. Although soil carbon stocks did not differ between the grazing regimes, stocks were positively associated with root\uffe2\uff80\uff90associated ascomycetes, typical to the year\uffe2\uff80\uff90round grazing regime, and negatively associated with free\uffe2\uff80\uff90living saprotrophs, typical to the winter grazing regime. These findings suggest that when grazers promote dominance of evergreen dwarf shrubs, they induce shifts in soil fungal communities that increase soil carbon sequestration in the long term. Thus, to predict climate\uffe2\uff80\uff90driven changes in soil carbon, grazer\uffe2\uff80\uff90induced shifts in vegetation and soil fungal communities need to be accounted for.

However, experimental control is often achieved at the expense of representativeness. Here, we present a data\uffe2\uff80\uff90driven reciprocal modelling framework to quantify the individual effects of environmental treatments under field conditions.

This is a letter to Waring et al., 27, e15\uffe2\uff80\uff93e16.The rising atmospheric CO2 concentration leads to a CO2 fertilization effect on plants\uffe2\uff80\uff94that is, increased photosynthetic uptake of CO2 by leaves and enhanced water\uffe2\uff80\uff90use efficiency (WUE). Yet, the resulting net impact of CO2 fertilization on plant growth and soil moisture (SM) savings at large scale is poorly understood. Drylands provide a natural experimental setting to detect the CO2 fertilization effect on plant growth since foliage amount, plant water\uffe2\uff80\uff90use and photosynthesis are all tightly coupled in water\uffe2\uff80\uff90limited ecosystems. A long\uffe2\uff80\uff90term change in the response of leaf area index (LAI, a measure of foliage amount) to changes in SM is likely to stem from changing water demand of primary productivity in water\uffe2\uff80\uff90limited ecosystems and is a proxy for changes in WUE. Using 34\uffe2\uff80\uff90year satellite observations of LAI and SM over tropical and subtropical drylands, we identify that a 1% increment in SM leads to 0.15% (\uffc2\uffb10.008, 95% confidence interval) and 0.51% (\uffc2\uffb10.01, 95% confidence interval) increments in LAI during 1982\uffe2\uff80\uff921998 and 1999\uffe2\uff80\uff922015, respectively. The increasing response of LAI to SM has contributed 7.2% (\uffc2\uffb13.0%, 95% confidence interval) to total dryland greening during 1999\uffe2\uff80\uff922015 compared to 1982\uffe2\uff80\uff921998. The increasing response of LAI to SM is consistent with the CO2 fertilization effect on WUE in water\uffe2\uff80\uff90limited ecosystems, indicating that a given amount of SM has sustained greater amounts of photosynthetic foliage over time. The LAI responses to changes in SM from seven dynamic global vegetation models are not always consistent with observations, highlighting the need for improved process knowledge of terrestrial ecosystem responses to rising atmospheric CO2 concentration.

In this context, the formation of the relatively long\uffe2\uff80\uff90lived mineral\uffe2\uff80\uff90associated organic carbon (MAOC) is key. To date, soils are considered to be limited in their ability to accumulate MAOC, mainly by the amount of clay and silt particles present. Using the comprehensive German Agricultural Soil Inventory, we selected 189 samples with a wide range of SOC (5\uffe2\uff80\uff93118\uffe2\uff80\uff89g\uffe2\uff80\uff89kg\uffe2\uff88\uff921) and clay contents (30\uffe2\uff80\uff93770\uffe2\uff80\uff89g\uffe2\uff80\uff89kg\uffe2\uff88\uff921) to test whether there is a detectable upper limit of MAOC content. We found that the proportion of MAOC was surprisingly stable for soils under cropland and grassland use across the whole range of bulk SOC contents. Soil texture influenced the slope of the relationship between bulk SOC and MAOC, but no upper limit was observed in any texture class. Also, C content in the fine fraction (g\uffe2\uff80\uff89C\uffe2\uff80\uff89kg\uffe2\uff88\uff921 fraction) was negatively correlated to fine fraction content (g\uffe2\uff80\uff89kg\uffe2\uff88\uff921 bulk soil). Both findings challenge the notion that MAOC accumulation is limited by soil fine fraction content per se.South China has been experiencing very high rate of acid deposition and severe soil acidification in recent decades, which has been proposed to exacerbate the regional ecosystem phosphorus (P) limitation. We conducted a 10\uffe2\uff80\uff90year field experiment of simulated acid deposition to examine how acidification impacts seasonal changes of different soil P fractions in a tropical forest with highly acidic soils in south China. As expected, acid addition significantly increased occluded P pool but reduced the other more labile P pools in the dry season. In the wet season, however, acid addition did not change microbial P, soluble P and labile organic P pools. Acid addition significantly increased exchangeable Al3+ and Fe3+ and the activation of Fe oxides in both seasons. Different from the decline of microbial abundance in the dry season, acid addition increased ectomycorrhizal fungi and its ratio to arbuscular mycorrhiza fungi in the wet season, which significantly stimulated phosphomonoesterase activities and likely promoted the dissolution of occluded P. Our results suggest that, even in already highly acidic soils, the acidification\uffe2\uff80\uff90induced P limitation could be alleviated by stimulating ectomycorrhizal fungi and phosphomonoesterase activities. The differential responses and microbial controls of seasonal soil P transformation revealed here should be implemented into ecosystem biogeochemical model for predicting plant productivity under future acid deposition scenarios.Meeting end\uffe2\uff80\uff90of\uffe2\uff80\uff90century global warming targets requires aggressive action on multiple fronts. Recent reports note the futility of addressing mitigation goals without fully engaging the agricultural sector, yet no available assessments combine both nature\uffe2\uff80\uff90based solutions (reforestation, grassland and wetland protection, and agricultural practice change) and cellulosic bioenergy for a single geographic region. Collectively, these solutions might offer a suite of climate, biodiversity, and other benefits greater than either alone. Nature\uffe2\uff80\uff90based solutions are largely constrained by the duration of carbon accrual in soils and forest biomass; each of these carbon pools will eventually saturate. Bioenergy solutions can last indefinitely but carry significant environmental risk if carelessly deployed. We detail a simplified scenario for the United States that illustrates the benefits of combining approaches. We assign a portion of non\uffe2\uff80\uff90forested former cropland to bioenergy sufficient to meet projected mid\uffe2\uff80\uff90century transportation needs, with the remainder assigned to nature\uffe2\uff80\uff90based solutions such as reforestation. Bottom\uffe2\uff80\uff90up mitigation potentials for the aggregate contributions of crop, grazing, forest, and bioenergy lands are assessed by including in a Monte Carlo model conservative ranges for cost\uffe2\uff80\uff90effective local mitigation capacities, together with ranges for (a) areal extents that avoid double counting and include realistic adoption rates and (b) the projected duration of different carbon sinks. The projected duration illustrates the net effect of eventually saturating soil carbon pools in the case of most strategies, and additionally saturating biomass carbon pools in the case of forest management. Results show a conservative end\uffe2\uff80\uff90of\uffe2\uff80\uff90century mitigation capacity of 110 (57\uffe2\uff80\uff93178) Gt CO2e for the U.S., ~50% higher than existing estimates that prioritize nature\uffe2\uff80\uff90based or bioenergy solutions separately. Further research is needed to shrink uncertainties, but there is sufficient confidence in the general magnitude and direction of a combined approach to plan for deployment now.Soil micronutrients are capital for the delivery of ecosystem functioning and food provision worldwide. Yet, despite their importance, the global biogeography and ecological drivers of soil micronutrients remain virtually unknown, limiting our capacity to anticipate abrupt unexpected changes in soil micronutrients in the face of climate change. Here, we analyzed >1300 topsoil samples to examine the global distribution of six metallic micronutrients (Cu, Fe, Mn, Zn, Co and Ni) across all continents, climates and vegetation types. We found that warmer arid and tropical ecosystems, present in the least developed countries, sustain the lowest contents of multiple soil micronutrients. We further provide evidence that temperature increases may potentially result in abrupt and simultaneous reductions in the content of multiple soil micronutrients when a temperature threshold of 12\uffe2\uff80\uff9314\uffc2\uffb0C is crossed, which may be occurring on 3% of the planet over the next century. Altogether, our findings provide fundamental understanding of the global distribution of soil micronutrients, with direct implications for the maintenance of ecosystem functioning, rangeland management and food production in the warmest and poorest regions of the planet.Unprecedented nitrogen (N) inputs into terrestrial ecosystems have profoundly altered soil N cycling. Ammonia oxidizers and denitrifiers are the main producers of nitrous oxide (N2O), but it remains unclear how ammonia oxidizer and denitrifier abundances will respond to N loading and whether their responses can predict N\uffe2\uff80\uff90induced changes in soil N2O emission. By synthesizing 101 field studies worldwide, we showed that N loading significantly increased ammonia oxidizer abundance by 107% and denitrifier abundance by 45%. The increases in both ammonia oxidizer and denitrifier abundances were primarily explained by N loading form, and more specifically, organic N loading had stronger effects on their abundances than mineral N loading. Nitrogen loading increased soil N2O emission by 261%, whereas there was no clear relationship between changes in soil N2O emission and shifts in ammonia oxidizer and denitrifier abundances. Our field\uffe2\uff80\uff90based results challenge the laboratory\uffe2\uff80\uff90based hypothesis that increased ammonia oxidizer and denitrifier abundances by N loading would directly cause higher soil N2O emission. Instead, key abiotic factors (mean annual precipitation, soil pH, soil C:N ratio, and ecosystem type) explained N\uffe2\uff80\uff90induced changes in soil N2O emission. Altogether, these findings highlight the need for considering the roles of key abiotic factors in regulating soil N transformations under N loading to better understand the microbially mediated soil N2O emission.Summer droughts strongly affect soil organic carbon (SOC) cycling, but net effects on SOC storage are unclear as drought affects both C inputs and outputs from soils. Here, we explored the overlooked role of soil fauna on SOC storage in forests, hypothesizing that soil faunal activity is particularly drought\uffe2\uff80\uff90sensitive, thereby reducing litter incorporation into the mineral soil and, eventually, long\uffe2\uff80\uff90term SOC storage.
In a drought\uffe2\uff80\uff90prone pine forest (Switzerland), we performed a large\uffe2\uff80\uff90scale irrigation experiment for 17\uffc2\uffa0years and assessed its impact on vertical SOC distribution and composition. We also examined litter mass loss of dominant tree species using different mesh\uffe2\uff80\uff90size litterbags and determined soil fauna abundance and community composition.
The 17\uffe2\uff80\uff90year\uffe2\uff80\uff90long irrigation resulted in a C loss in the organic layers (\uffe2\uff88\uff921.0\uffc2\uffa0kg\uffc2\uffa0C\uffc2\uffa0m\uffe2\uff88\uff922) and a comparable C gain in the mineral soil (+0.8\uffc2\uffa0kg\uffc2\uffa0C\uffc2\uffa0m\uffe2\uff88\uff922) and thus did not affect total SOC stocks. Irrigation increased the mass loss ofQuercus pubescensandViburnum lantanaleaf litter, with greater effect sizes when meso\uffe2\uff80\uff90 and macrofauna were included (+215%) than when excluded (+44%). The enhanced faunal\uffe2\uff80\uff90mediated litter mass loss was paralleled by a many\uffe2\uff80\uff90fold increase in the abundance of meso\uffe2\uff80\uff90 and macrofauna during irrigation. Moreover, Acari and Collembola community composition shifted, with a higher presence of drought\uffe2\uff80\uff90sensitive species in irrigated soils. In comparison, microbial SOC mineralization was less sensitive to soil moisture. Our results suggest that the vertical redistribution of SOC with irrigation was mainly driven by faunal\uffe2\uff80\uff90mediated litter incorporation, together with increased root C inputs.
Our study shows that soil fauna is highly sensitive to natural drought, which leads to a reduced C transfer from organic layers to the mineral soil. In the longer term, this potentially affects SOC storage and, therefore, soil fauna plays a key but so far largely overlooked role in shaping SOC responses to drought.In Arctic regions, thawing permafrost soils are projected to release 50 to 250 Gt of carbon by 2100. This data is mostly derived from carbon\uffe2\uff80\uff90rich wetlands, although 71% of this carbon pool is stored in faster\uffe2\uff80\uff90thawing mineral soils, where ecosystems close to the outer boundaries of permafrost regions are especially vulnerable. Although extensive data exists from currently thawing sites and short\uffe2\uff80\uff90term thawing experiments, investigations of the long\uffe2\uff80\uff90term changes following final thaw and co\uffe2\uff80\uff90occurring drainage are scarce. Here we show ecosystem changes at two comparable tussock tundra sites with distinct permafrost thaw histories, representing 15 and 25\uffc2\uffa0years of natural drainage, that resulted in a 10\uffe2\uff80\uff90fold decrease in CH4 emissions (3.2\uffc2\uffa0\uffc2\uffb1\uffc2\uffa02.2 vs. 0.3\uffc2\uffa0\uffc2\uffb1\uffc2\uffa00.4\uffc2\uffa0mg C\uffe2\uff80\uff90CH4\uffc2\uffa0m\uffe2\uff88\uff922\uffc2\uffa0day\uffe2\uff88\uff921), while CO2 emissions were comparable. These data extend the time perspective from earlier studies based on short\uffe2\uff80\uff90term experimental drainage. The overall microbial community structures did not differ significantly between sites, although the drier top soils at the most advanced site led to a loss of methanogens and their syntrophic partners in surface layers while the abundance of methanotrophs remained unchanged. The resulting deeper aeration zones likely increased CH4 oxidation due to the longer residence time of CH4 in the oxidation zone, while the observed loss of aerenchyma plants reduced CH4 diffusion from deeper soil layers directly to the atmosphere. Our findings highlight the importance of including hydrological, vegetation and microbial specific responses when studying long\uffe2\uff80\uff90term effects of climate change on CH4 emissions and underscores the need for data from different soil types and thaw histories.Peatlands at high latitudes have accumulated >400\uffe2\uff80\uff89Pg carbon (C) because saturated soil and cold temperatures suppress C decomposition. 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. Peatlands with the initial WT close to the soil surface were more vulnerable to C loss: Non\uffe2\uff80\uff90permafrost peatlands lost >2\uffe2\uff80\uff89kg\uffe2\uff80\uff89C\uffe2\uff80\uff89m\uffe2\uff88\uff922 over 100\uffe2\uff80\uff89years when WT is lowered by 50\uffe2\uff80\uff89cm, while permafrost peatlands temporally switched from C sinks to sources. 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.Soil microbiology has entered into the big data era, but the challenges in bridging laboratory\uffe2\uff80\uff90, field\uffe2\uff80\uff90, and model\uffe2\uff80\uff90based studies of ecosystem functions still remain. Indeed, the limitation of factors in laboratory experiments disregards interactions of a broad range of in situ environmental drivers leading to frequent contradictions between laboratory\uffe2\uff80\uff90 and field\uffe2\uff80\uff90based studies, which may consequently mislead model development and projections. Upscaling soil microbiology research from laboratory to ecosystems represents one of the grand challenges facing environmental scientists, but with great potential to inform policymakers toward climate\uffe2\uff80\uff90smart and resource\uffe2\uff80\uff90efficient ecosystems. The upscaling is not only a scale problem, but also requires disentangling functional relationships and processes on each level. We point to three potential reasons for the gaps between laboratory\uffe2\uff80\uff90 and field\uffe2\uff80\uff90based studies (i.e., spatiotemporal dynamics, sampling disturbances, and plant\uffe2\uff80\uff93soil\uffe2\uff80\uff93microbial feedbacks), and three key issues of caution when bridging observations and model predictions (i.e., across\uffe2\uff80\uff90scale effect, complex\uffe2\uff80\uff90process coupling, and multi\uffe2\uff80\uff90factor regulation). Field\uffe2\uff80\uff90based studies only cover a limited range of environmental variation that must be supplemented by laboratory and mesocosm manipulative studies when revealing the underlying mechanisms.

This uncertainty prevents models from adequately capturing SOC dynamics and challenges the assessment of management and climate change effects on soils. Reducing these uncertainties requires simultaneous investigation of factors controlling the amount (SOC abundance) and duration (SOC persistence) of stored C. We present a global synthesis of SOC and radiocarbon profiles (nProfile\uffe2\uff80\uff89=\uffe2\uff80\uff89597) to assess the timescales of SOC storage. We use a combination of statistical and depth\uffe2\uff80\uff90resolved compartment models to explore key factors controlling the relationships between SOC abundance and persistence across pedo\uffe2\uff80\uff90climatic regions and with soil depth. This allows us to better understand (i) how SOC abundance and persistence covary across pedo\uffe2\uff80\uff90climatic regions and (ii) how the depth dependence of SOC dynamics relates to climatic and mineralogical controls on SOC abundance and persistence. We show that SOC abundance and persistence are differently related; the controls on these relationships differ substantially between major pedo\uffe2\uff80\uff90climatic regions and soil depth. For example, large amounts of persistent SOC can reflect climatic constraints on soils (e.g., in tundra/polar regions) or mineral absorption, reflected in slower decomposition and vertical transport rates. In contrast, lower SOC abundance can be found with lower SOC persistence (e.g., in highly weathered tropical soils) or higher SOC persistence (e.g., in drier and less productive regions). We relate variable patterns of SOC abundance and persistence to differences in the processes constraining plant C input, microbial decomposition, vertical C transport and mineral SOC stabilization potential. This process\uffe2\uff80\uff90oriented grouping of SOC abundance and persistence provides a valuable benchmark for global C models, highlighting that pedo\uffe2\uff80\uff90climatic boundary conditions are crucial for predicting the effects of climate change and soil management on future C abundance and persistence.Integrated food and bioenergy production is a promising way to ensure regional/national food and energy security, efficient use of soil resources, and enhanced biodiversity, while contributing to the abatement of CO2 emissions. The objective of this study was to assess alternative crop rotation schemes as the basis for integrating and enhancing the sustainable biomass production within the food\uffe2\uff80\uff90energy agricultural context. Sunn hemp (Crotalaria spp.) in rotation with wheat (Triticum spp.) in the EU and with sugarcane (Saccharum spp.) in Brazil were evaluated. Sunn hemp did not negatively affect crop's productivity and soil fertility; wheat grain yields were maintained around the mean regional production levels (6, 7, 3 and Mg ha\uffe2\uff88\uff921 in Greece, Italy, and Spain, respectively), and the cumulative biomass in the extended rotation (wheat straw+sunn hemp) was between 1.5 and 2.0 times higher than in the conventional rotation. In Brazil, sugarcane stalks yield in clay soils increased by around 15\uffc2\uffa0Mg ha\uffe2\uff88\uff921\uffc2\uffa0year\uffe2\uff88\uff921 under sunn hemp rotation in comparison with bare fallow. Moreover, sunn hemp in the EU rotations did not have negative effects on soil available macronutrients, organic matter, pH, and cation exchange capacity, neither on C and N stocks in Brazil. The qualitative characteristics (mineral, ash, and hemicelluloses contents) of the cumulated biomass were somehow higher (in average +26%, +35%, and +3.4%, respectively) than in the conventional system. In summary, in temperate and tropical climates the integration of dedicated biomass legume crops within conventional systems could lead to enhanced biomass availability, crop diversification, and efficient use (in space and time) of the land resources.

However, the factors and mechanisms determining the responses of soil AOA:AOB and nitrification to N loading are still unclear, making it difficult to predict future changes in soil nitrification. Herein, we synthesize\uffc2\uffa068 field studies around the world to evaluate the impacts of N loading on soil ammonia oxidizers and nitrification. Across a wide range of biotic and abiotic factors, climate is the most important driver of the responses of AOA:AOB to N loading. Climate does not directly affect the N\uffe2\uff80\uff90stimulation of nitrification, but does so via climate\uffe2\uff80\uff90related shifts in AOA:AOB. Specifically, climate modulates the responses of AOA:AOB to N loading by affecting soil pH, N\uffe2\uff80\uff90availability and moisture. AOB play a dominant role in affecting nitrification in dry climates, while the impacts from AOA can exceed AOB in humid climates. Together, these results suggest that climate\uffe2\uff80\uff90related shifts in soil ammonia\uffe2\uff80\uff90oxidizing community maintain the N\uffe2\uff80\uff90stimulation of nitrification, highlighting the importance of microbial community composition in mediating the responses of the soil N cycle to N loading.Soils store large quantities of carbon in the subsoil (below 0.2\uffe2\uff80\uff89m depth) that is generally old and believed to be stabilized over centuries to millennia, which suggests that subsoil carbon sequestration (CS) can be used as a strategy for climate change mitigation. In this article, we review the main biophysical processes that contribute to carbon storage in subsoil and the main mathematical models used to represent these processes. Our guiding objective is to review whether a process understanding of soil carbon movement in the vertical profile can help us to assess carbon storage and persistence at timescales relevant for climate change mitigation. Bioturbation, liquid phase transport, belowground carbon inputs, mineral association, and microbial activity are the main processes contributing to the formation of soil carbon profiles, and these processes are represented in models using the diffusion\uffe2\uff80\uff93advection\uffe2\uff80\uff93reaction paradigm. Based on simulation examples and measurements from carbon and radiocarbon profiles across biomes, we found that advective and diffusive transport may only play a secondary role in the formation of soil carbon profiles. The difference between vertical root inputs and decomposition seems to play a primary role in determining the shape of carbon change with depth. Using the transit time of carbon to assess the timescales of carbon storage of new inputs, we show that only small quantities of new carbon inputs travel through the profile and can be stabilized for time horizons longer than 50\uffe2\uff80\uff89years, implying that activities that promote CS in the subsoil must take into consideration the very small quantities that can be stabilized in the long term.Emerging evidence points out that the responses of soil organic carbon (SOC) to nitrogen (N) addition differ along the soil profile, highlighting the importance of synthesizing results from different soil layers. Here, using a global meta\uffe2\uff80\uff90analysis, we found that N addition significantly enhanced topsoil (0\uffe2\uff80\uff9330\uffe2\uff80\uff89cm) SOC by 3.7% (\uffc2\uffb11.4%) in forests and grasslands. In contrast, SOC in the subsoil (30\uffe2\uff80\uff93100\uffe2\uff80\uff89cm) initially increased with N addition but decreased over time. The model selection analysis revealed that experimental duration and vegetation type are among the most important predictors across a wide range of climatic, environmental, and edaphic variables. The contrasting responses of SOC to N addition indicate the importance of considering deep soil layers, particularly for long\uffe2\uff80\uff90term continuous N deposition. Finally, the lack of depth\uffe2\uff80\uff90dependent SOC responses to N addition in experimental and modeling frameworks has likely resulted in the overestimation of changes in SOC storage under enhanced N deposition.The global spread of woody plants into grasslands is predicted to increase over the coming century. While there is general agreement regarding the anthropogenic causes of this phenomenon, its ecological consequences are less certain. We analysed how woody vegetation of differing cover affects plant diversity (richness and evenness) and the surrogates of multiple ecosystem processes (multifunctionality) in global drylands, and how these change with aridity.
LocationTwo hundred and twenty\uffe2\uff80\uff90four dryland sites from all continents except Antarctica, widely differing in their environmental conditions (from arid to dry\uffe2\uff80\uff90subhumid sites) and relative woody cover (from 0 to 100%).
MethodsUsing a standardized field survey, we measured the cover, richness and evenness of perennial vegetation. At each site, we measured 14 soil variables related to fertility and the build\uffe2\uff80\uff90up of nutrient pools. These variables are critical for maintaining ecosystem functioning in drylands.
ResultsSpecies richness and ecosystem multifunctionality were strongly related to woody vegetation, with both variables peaking at a relative woody cover (RWC) of 41\uffe2\uff80\uff9360%. This relationship shifted with aridity. We observed linear positive effects of RWC in dry\uffe2\uff80\uff90subhumid sites. These positive trends shifted to hump\uffe2\uff80\uff90shaped RWC\uffe2\uff80\uff93diversity and multifunctionality relationships under semi\uffe2\uff80\uff90arid environments. Finally, hump\uffe2\uff80\uff90shaped (richness, evenness) or linear negative (multifunctionality) effects of RWC were found under the most arid conditions.
Main conclusionsPlant diversity and multifunctionality peaked at intermediate levels of woody cover, although this relationship became increasingly positive in wetter environments. This comprehensive study accounts for multiple ecosystem attributes across a range of levels of woody cover and environmental conditions. Our results help us to reconcile contrasting views of woody encroachment found in the current literature and can be used to improve predictions of the likely effects of encroachment on biodiversity and ecosystem services.

Previous studies have shown that the amount and age of soil carbon are strongly affected by the interaction of climate, vegetation, and mineralogy. However, these findings are primarily based on studies from temperate regions and from fine\uffe2\uff80\uff90scale studies, leaving large knowledge gaps for soils from understudied regions such as sub\uffe2\uff80\uff90Saharan Africa. In addition, there is a lack of data to validate modeled soil C dynamics at broad scales. Here, we present insights into organic carbon cycling, based on a new broad\uffe2\uff80\uff90scale radiocarbon and mineral dataset for sub\uffe2\uff80\uff90Saharan Africa. We found that in moderately weathered soils in seasonal climate zones with poorly crystalline and reactive clay minerals, organic carbon persists longer on average (topsoil: 201\uffe2\uff80\uff89\uffc2\uffb1\uffe2\uff80\uff89130\uffe2\uff80\uff89years; subsoil: 645\uffe2\uff80\uff89\uffc2\uffb1\uffe2\uff80\uff89385\uffe2\uff80\uff89years) than in highly weathered soils in humid regions (topsoil: 140\uffe2\uff80\uff89\uffc2\uffb1\uffe2\uff80\uff8946\uffe2\uff80\uff89years; subsoil: 454\uffe2\uff80\uff89\uffc2\uffb1\uffe2\uff80\uff89247\uffe2\uff80\uff89years) with less reactive minerals. Soils in arid climate zones (topsoil: 396\uffe2\uff80\uff89\uffc2\uffb1\uffe2\uff80\uff89339\uffe2\uff80\uff89years; subsoil: 963\uffe2\uff80\uff89\uffc2\uffb1\uffe2\uff80\uff89669\uffe2\uff80\uff89years) store organic carbon for periods more similar to those in seasonal climate zones, likely reflecting climatic constraints on weathering, carbon inputs and microbial decomposition. These insights into the timescales of organic carbon persistence in soils of sub\uffe2\uff80\uff90Saharan Africa suggest that a process\uffe2\uff80\uff90oriented grouping of soils based on pedo\uffe2\uff80\uff90climatic conditions may be useful to improve predictions of soil responses to climate change at broader scales. Munoz et\u00a0al. (2024) raised concerns regarding our recent contribution and the definition of the term C sequestration in soils (Don et\u00a0al., 2024). We performed a review and therefore based our analysis on existing definitions of C sequestrations, mainly by the IPCC. We recommend sticking with terminologies around C sequestration and climate mitigation, as outlined in our review, in order to keep it consistent and manageable.
Although substantial advances in predicting the ecological impacts of global change have been made, predictions of the evolutionary impacts have lagged behind. In soil ecosystems, microbes act as the primary energetic drivers of carbon cycling; however, microbes are also capable of evolving on timescales comparable to rates of global change. Given the importance of soil ecosystems in global carbon cycling, we assess the potential impact of microbial evolution on carbon\uffe2\uff80\uff90climate feedbacks in this system. We begin by reviewing the current state of knowledge concerning microbial evolution in response to global change and its specific effect on soil carbon dynamics. Through this integration, we synthesize a roadmap detailing how to integrate microbial evolution into ecosystem biogeochemical models. Specifically, we highlight the importance of microscale mechanistic soil carbon models, including choosing an appropriate evolutionary model (e.g., adaptive dynamics, quantitative genetics), validating model predictions with \uffe2\uff80\uff98omics\uffe2\uff80\uff99 and experimental data, scaling microbial adaptations to ecosystem level processes, and validating with ecosystem\uffe2\uff80\uff90scale measurements. The proposed steps will require significant investment of scientific resources and might require 10\uffe2\uff80\uff9320\uffe2\uff80\uff89years to be fully implemented. However, through the application of multi\uffe2\uff80\uff90scale integrated approaches, we will advance the integration of microbial evolution into predictive understanding of ecosystems, providing clarity on its role and impact within the broader context of environmental change.Current biogeochemical models produce carbon\uffe2\uff80\uff93climate feedback projections with large uncertainties, often attributed to their structural differences when simulating soil organic carbon (SOC) dynamics worldwide. However, choices of model parameter values that quantify the strength and represent properties of different soil carbon cycle processes could also contribute to model simulation uncertainties. Here, we demonstrate the critical role of using common observational data in reducing model uncertainty in estimates of global SOC storage. Two structurally different models featuring distinctive carbon pools, decomposition kinetics, and carbon transfer pathways simulate opposite global SOC distributions with their customary parameter values yet converge to similar results after being informed by the same global SOC database using a data assimilation approach. The converged spatial SOC simulations result from similar simulations in key model components such as carbon transfer efficiency, baseline decomposition rate, and environmental effects on carbon fluxes by these two models after data assimilation. Moreover, data assimilation results suggest equally effective simulations of SOC using models following either first\uffe2\uff80\uff90order or Michaelis\uffe2\uff80\uff93Menten kinetics at the global scale. Nevertheless, a wider range of data with high\uffe2\uff80\uff90quality control and assurance are needed to further constrain SOC dynamics simulations and reduce unconstrained parameters. New sets of data, such as microbial genomics\uffe2\uff80\uff90function relationships, may also suggest novel structures to account for in future model development. Overall, our results highlight the importance of observational data in informing model development and constraining model predictions.Global soil nitrogen (N) cycling remains poorly understood due to its complex driving mechanisms. Here, we present a comprehensive analysis of global soil \uffce\uffb415N, a stable isotopic signature indicative of the N input\uffe2\uff80\uff93output balance, using a machine\uffe2\uff80\uff90learning approach on 10,676 observations from 2670 sites. Our findings reveal prevalent joint effects of climatic conditions, plant N\uffe2\uff80\uff90use strategies, soil properties, and other natural and anthropogenic forcings on global soil \uffce\uffb415N. The joint effects of multiple drivers govern the latitudinal distribution of soil \uffce\uffb415N, with more rapid N cycling at lower latitudes than at higher latitudes. In contrast to previous climate\uffe2\uff80\uff90focused models, our data\uffe2\uff80\uff90driven model more accurately simulates spatial changes in global soil \uffce\uffb415N, highlighting the need to consider the joint effects of multiple drivers to estimate the Earth's N budget. These insights contribute to the reconciliation of discordances among empirical, theoretical, and modeling studies on soil N cycling, as well as sustainable N management.Converting natural vegetation for agriculture has resulted in the loss of approximately 5% of the current global terrestrial soil organic carbon (SOC) stock to the atmosphere. Increasing the agricultural area under grassland may reverse some of these losses, but the effectiveness of such a strategy is limited by how quickly SOC recovers after conversion from cropland. Using soil data and extensive land\uffe2\uff80\uff90use histories gathered during the national German agricultural soil inventory, this study aims to answer three questions regarding agricultural land\uffe2\uff80\uff90use change (LUC): (i) how do SOC stocks change with depth following LUC; (ii) how long does it take to reach SOC equilibrium after LUC; and (iii) what is the legacy effect of historic LUC on present day SOC dynamics? By using a novel approach that substitutes space for time and accounts for differences in site properties using propensity score balancing, we determined that sites that were converted from cropland to grassland reached a SOC equilibrium level 47.3% (95% confidence interval (CI): 43.4% to 49.5%) above permanent cropland levels 83\uffe2\uff80\uff89years (95% CI: 79 to 90\uffe2\uff80\uff89years) after conversion. Meanwhile, sites converted from grassland to cropland reached a SOC equilibrium level \uffe2\uff88\uff9233.6% (95% CI: \uffe2\uff88\uff9234.1% to \uffe2\uff88\uff9233.5%) below permanent grassland levels after 180\uffe2\uff80\uff89years (95% CI: 151 to 223\uffe2\uff80\uff89years). We estimate that, over the past century, today's German agricultural soils (16.6\uffe2\uff80\uff89million\uffe2\uff80\uff89ha) have gained about 40\uffe2\uff80\uff89million\uffe2\uff80\uff89Mg\uffe2\uff80\uff89C. Furthermore, croplands with historic LUC from grassland are losing SOC by \uffe2\uff88\uff920.26\uffe2\uff80\uff89Mg\uffe2\uff80\uff89ha\uffe2\uff88\uff921\uffe2\uff80\uff89year\uffe2\uff88\uff921 (10% of agricultural land) while grasslands historically converted from cropland are gaining SOC by 0.27\uffe2\uff80\uff89Mg\uffe2\uff80\uff89ha\uffe2\uff88\uff921\uffe2\uff80\uff89year\uffe2\uff88\uff921 (18% of agricultural land). This study shows that even long\uffe2\uff80\uff90standing temperate agricultural sites likely have ongoing SOC change as a result of historical LUC.Climate change is causing an intensification of soil drying and rewetting events, altering microbial functioning and potentially destabilizing soil organic carbon. After rewetting, changes in microbial community carbon use efficiency (CUE), investment in life history strategies, and fungal to bacterial dominance co\uffe2\uff80\uff90occur. Still, we have yet to generalize what drives these dynamic responses. Here, we collated 123 time series of microbial community growth (G, sum of fungal and bacterial growth, evaluated by leucine and acetate incorporation, respectively) and respiration (R) after rewetting and calculated CUE\uffe2\uff80\uff89=\uffe2\uff80\uff89G/(G\uffe2\uff80\uff89+\uffe2\uff80\uff89R). First, we characterized CUE recovery by two metrics: maximum CUE and time to maximum CUE. Second, we translated microbial growth and respiration data into microbial investments in life history strategies (high yield (Y), resource acquisition (A), and stress tolerance (S)). Third, we characterized the temporal change in fungal to bacterial dominance. Finally, the metrics describing the CUE recovery, investment in life history strategies, and fungal to bacterial dominance after rewetting were explained by environmental factors and microbial properties. CUE increased after rewetting as fungal dominance declined, but the maximum CUE was explained by the CUE under moist conditions, rather than specific environmental factors. In contrast, higher soil pH and carbon availability accelerated the decline of microbial investment in stress tolerance and fungal dominance. We conclude that microbial CUE recovery is mostly driven by the shifting microbial community composition and the metabolic capacity of the community, whereas changes in microbial investment in life history strategies and fungal versus bacterial dominance depend on soil pH and carbon availability.Tree diseases are increasingly affecting woodland ecosystems across the world. However, the impact of these diseases upon the soil, and in particular soil carbon, is still poorly understood. Here we present the results of a field survey of ~100 woodlands across Great Britain measured in 1971, 2001 and 2022 and evaluate the fifty\uffe2\uff80\uff90year trend in topsoil (0\uffe2\uff80\uff9315\uffe2\uff80\uff89cm) carbon based upon measurements of soil organic matter (SOM) and the impact of Hymenoscyphus fraxineus (ash dieback). To better represent the full SOM distribution, including the extremely high SOM measurements, we adopt a Beta mixture modelling approach within a Bayesian framework. Across all woodlands, comprising ~1,500 plots per survey, average SOM remained constant across the fifty\uffe2\uff80\uff90year time series. However, the 311 plots with ash dieback had lower SOM in the most recent survey compared to the 328 plots with ash trees present but no dieback recorded, due to a slight decline in SOM under ash dieback. This resulted in plots with ash dieback having a modelled mean SOM of 12.2% compared to 13.4% in plots without ash dieback, a difference of 1.23 percentage points (95% CI 0.25\uffe2\uff80\uff932.21). Ash dieback was more likely to be recorded in plots that had higher soil pH pre\uffe2\uff80\uff90ash dieback invasion, but the decline in SOM under ash dieback was not explained by changes in soil pH or changes in the ground flora composition. Converting our results to soil C and extrapolating for broadleaved woodland across the entirety of Great Britain, the total amount of topsoil carbon lost to date due to ash dieback could be 6 MtCO2 (\uffc2\uffb1\uffe2\uff80\uff894\uffe2\uff80\uff89s.d.). Our results show the importance of understanding the impacts of tree disease when considering current and future woodland carbon dynamics.Unsustainable soil management, climate change, and land degradation jeopardize soil biodiversity and soil\uffe2\uff80\uff90mediated ecosystem functions. Although the transition from conventional to organic agriculture has been proposed as a potential solution to alleviate these pressures, there is limited evidence of its effectiveness in enhancing belowground biodiversity across different biogeographical regions, climates, and land degradation levels. In this study, we holistically assessed the status of soil biodiversity, from microorganisms to meso\uffe2\uff80\uff90 and macrofauna, in agroecosystems distributed across four continents. We identified the primary environmental community composition drivers and assessed the effects of the transition from conventional to organic management (no chemical inputs) on soil ecology. Our findings highlight the mean temperature and precipitation of the warmest and coldest quarters of the year, aridity, pH, and soil texture as the primary drivers of the different soil biodiversity components. Overall, organic farming has a significant but small impact on soil biodiversity compared to the other community drivers. On top of that, the results demonstrate the importance of a regional\uffe2\uff80\uff90specific context for a future generalized transition towards organic soil management. Specifically, under the most arid conditions in our study, organic management showed potential to buffer biodiversity loss in highly degraded soils, with a significant increase in diversity for prokaryotes and protists compared to conventionally managed soils. Therefore, the combination of a global and, simultaneously, regional\uffe2\uff80\uff90specific approach supports the hypothesis that a shift towards organic agriculture would maximize its beneficial impact on belowground diversity in highly degraded soils under arid conditions over the coming years, being a crucial tool to increase resilience and adaptation to global change for agriculture.Warming alters soil microbial traits through ecological and evolutionary processes, directly influencing the decomposition of organic matter, which significantly affects global soil carbon emissions. Yet, soil carbon models largely ignore these processes and their implications for global responses to warming. Here, we incorporate eco\uffe2\uff80\uff90evolutionary theory into a mechanistic model describing microbial soil carbon decomposition to address the question of whether such processes could have consequential effects on climate carbon feedbacks globally. We assume that a key trait of microbes, their resource allocation to production of exoenzymes (which facilitate decomposition of organic matter)\uffe2\uff80\uff94is optimized to environmental temperatures by natural selection. We find that eco\uffe2\uff80\uff90evolutionary optimization results in microbes allocating more resources to enzyme production under warming. When applied at the global scale, eco\uffe2\uff80\uff90evolutionary optimization enhances the biological realism of soil carbon models and significantly amplifies global soil carbon loss by 2100. Our results highlight the significant potential of microbial eco\uffe2\uff80\uff90evolutionary responses to influence carbon cycle feedbacks to climate change, and motivate an urgent need for more comprehensive data to accurately quantify the adaptive potential of microbiomes in response to climate change.Our objective was to test how a long\uffe2\uff80\uff90term increased water limitation affects structural and functional properties of a Mediterranean ecosystem, and how these changes modify the response of the main carbon fluxes to climatic controls. In 2003, a 27% throughfall exclusion experiment was installed in a Quercus ilex L. forest in France. Gross primary production (GPP), ecosystem respiration (RECO) and net ecosystem exchange (NEE) were estimated in a control and a dry treatment. Decreasing throughfall decreased GPP by 14% and had a smaller effect on RECO (\uffe2\uff88\uff9212%), especially soil respiration RS (\uffe2\uff88\uff9211%). Interannual variability of GPP (29%) was higher than for RECO (12%). Error propagation was used to estimates uncertainties in the NEE fluxes, which ranged from 3% to 10% in the control treatment but up to 167% for NEE in the dry treatment because more steps and data types were involved in the scaling. After 3 years of throughfall exclusion, we found no acclimation of RS to climatic drivers. Functional properties of the response of RS to soil water, temperature and rain pulse remained similar in the control and the dry treatments. A diurnal clockwise hysteresis in RS was probably controlled by canopy photosynthesis with a 3\uffe2\uff80\uff83h lag. The proportion of diurnal variation of respiration due to photosynthesis was similar in all treatments (4\uffe2\uff80\uff935%). Because of the characteristic of rain in Mediterranean climates, a continuous decrease of water input in these environments have an effect on topsoil water and consequently on RS only during short periods when rainfall is characterized by infrequent and small events that does not allow the topsoil to reach field capacity and does not allow to dry completely. However, in the longer term, we expect a stronger decrease in RS in the dry treatment driven by the decrease in GPP.

In the laboratory, under controlled temperature and equalised gravimetric water content, biochar amendment suppressed soilCO2emissions by 53% and net soilCO2eq. emissions by 55%.

These findings demonstrate that biochar amendment has the potential to suppress net soilCO2eq. emissions in bioenergy crop systems for up to 2\uffc2\uffa0years after addition, primarily through reducedCO2emissions. Suppression of soilCO2emissions may be due to a combined effect of reduced enzymatic activity, the increased carbon\uffe2\uff80\uff90use efficiency from the co\uffe2\uff80\uff90location of soil microbes, soil organic matter and nutrients and the precipitation ofCO2onto the biochar surface. We conclude that hardwood biochar has the potential to improve theGHGbalance of bioenergy crops through reductions in net soilCO2eq. emissions.

Both utilize the ability of plants to assimilate atmosphericCO2, and are thus intrinsically linked with soil processes. Research to date has shown that biochar and bioenergy cropping change both aboveground and belowground carbon cycling and soil fertility. Little is known, however, about the form and function of soil food webs in these altered ecosystems, or of the consequences of biodiversity changes at higher trophic levels for soil carbon sequestration. Hitherto studies on this topic have been chiefly observational, and often report contrasting results, thus adding little mechanistic understanding of biochar and bioenergy cropping impacts on soil organisms and linked ecosystem processes. This means it is difficult to predict, or control for, changes in biotic carbon cycling arising from biochar and bioenergy cropping. In this study we explore the potential mechanisms by which soil communities might be affected by biochar, particularly in soils which support bioenergy cropping. We outline the abiotic (soil quality\uffe2\uff80\uff90mediated) and biotic (plant\uffe2\uff80\uff90 and microbe\uffe2\uff80\uff90mediated) shifts in the soil environment, and implications for the abundance, diversity, and composition of soil faunal communities.

The aim of our study was to determine the potential carbon sequestration of the two chars at different timescales. We investigated the modification in composition and stability resulting from physical weathering of two different chars produced (i) at low temperature (250\uffc2\uffa0\uffc2\uffb0C) by hydrothermal carbonization (HTC); and (ii) at high temperature (1200\uffc2\uffa0\uffc2\uffb0C) by gasification (GS) using contrasting feedstocks. Physical weathering of HTC and GS placed on a water permeable canvas was performed through successive wetting/drying and freezing/thawing cycles. Carbon loss was assessed by mass balance. Chemical stability of the remaining material was evaluated as resistance to acid dichromate oxidation, and biological stability was assessed during laboratory incubation. Moreover, we assessed modification in potential priming effects due to physical weathering. Physical weathering induced a carbon loss ranging between 10 and 40% of the total C mass depending on the feedstock. This C loss is most probably related to leaching of small particulate and dissolved compounds. GS produced from maize silage showed the highest C loss. The chemical stability of HTC and GS was unaffected by physical weathering. In contrast, physical weathering strongly increased the biological stability of HTC and GS char produced from maize silage. After physical weathering, the half\uffe2\uff80\uff90life (t1/2) of GS was doubled but only slight increase was noted for those of HTC. During the first weeks of incubation, HTC addition to soil stimulated native soil organic matter (SOM) mineralization (positive priming effect), while the GS addition led to protection of the native SOM against biologic degradation (negative priming effect). Physical weathering led to reduction in these priming effects. Model extrapolations based on our data showed that decadal C sequestration potential of GS and HTC is globally equivalent when all losses including those due to priming and physical weathering were taken into account. However, at century scale only GS may have the potential to increase soil C storage.

Compared to baseline values, stover retention increased average SOC stocks temporally at a rate of 0.41\uffc2\uffa0Mg C\uffc2\uffa0ha\uffe2\uff88\uff921\uffc2\uffa0year\uffe2\uff88\uff921 (statistically significant at p\uffc2\uffa0<\uffc2\uffa00.01 when averaged across all soil layers). Although SOC sequestration rates were lower with stover removal, with moderate (<50%) removal they can be positive, thus emphasizing the importance of site\uffe2\uff80\uff90specific management. Our results also showed that tillage effects on SOC stocks were inconsistent due to the high variability in practices used among the experimental sites. Finally, we conclude that research and technological efforts should continue to be given high priority because of the importance in providing science\uffe2\uff80\uff90based policy recommendations for long\uffe2\uff80\uff90term global carbon management.
