Appropriate cover crop (CC) management is an important tool for the improvement of soil carbon stock; however, the relationships between carbon accumulation and CC root traits remain unclear. A literature review was performed to identify the extent and focus of recent research and to answer questions about the role of root traits of CCs in soil C accumulation with regard to species selection, mixture composition and agronomic management. The findings based on the analysis of 69 publications show that a range of root traits such as root biomass, architecture, depth of rooting, root chemical composition, as well as quantity and quality of rhizodeposition, can contribute to soil structure formation and C accumulation. These traits are usually species specific, and it seems that appropriate species combinations in the mixtures can offer the highest potential for optimization of C stock across various environments. However, there has been twice as much recent research on roots of CC monocultures than on mixtures, with little attention paid to agronomic aspects such as plant spatial arrangement or soil tillage in relation to CC root development. Considerations of real management under field conditions could be beneficial in providing greater accuracy of estimation of the contribution of CCs in increasing the SOC stock in croplands.The interactive effects of multiple global change drivers on terrestrial carbon (C) storage remain poorly understood. Here, we synthesise data from 633 published studies to show how the interactive effects of multiple drivers are generally additive (i.e. not differing from the sum of their individual effects) rather than synergistic or antagonistic. We further show that (1) elevatedCO2, warming, N addition, P addition and increased rainfall, all exerted positive individual effects on plant C pools at both single\uffe2\uff80\uff90plant and plant\uffe2\uff80\uff90community levels; (2) plant C pool responses to individual or combined effects of multiple drivers are seldom scale\uffe2\uff80\uff90dependent (i.e. not differing from single\uffe2\uff80\uff90plant to plant\uffe2\uff80\uff90community levels) and (3) soil and microbial biomass C pools are significantly less sensitive than plant C pools to individual or combined effects. We provide a quantitative basis for integrating additive effects of multiple global change drivers into future assessments of the C storage ability of terrestrial ecosystems.

Isotopic signatures (\uffce\uffb4 13 C) are used to assess the C origin of SOC or SIC. However, as measuring SOC and SIC contents, measuring \uffce\uffb4 13 C SOC and \uffce\uffb4 13 C SIC on a non\uffe2\uff80\uff90pretreated aliquot remains a challenge. Thermal analyses, like the Rock\uffe2\uff80\uff90Eval (RE) analysis, are promising to quantify SOC and SIC in a single analysis, but, to our knowledge, no development was conducted to assess \uffce\uffb4 13 C SOC and \uffce\uffb4 13 C SIC . We coupled a RE device to an isotopic gas analyser (Picarro) to continuously measure \uffce\uffb4 13 C CO2 and approach \uffce\uffb4 13 C SOC and \uffce\uffb4 13 C SIC . We hypothesised that different carbonate mineralogies and/or crystal sizes in SIC involve fluctuations of the \uffce\uffb4 13 C CO2 . Two calcareous soils, a lithogenic (calcite) and a biogenic (snail shell) carbonate, and five calcite/shell mixes were analysed with the RE\uffe2\uff80\uff90Picarro setup.

The RE\uffe2\uff80\uff90Picarro setup is promising to assess SOC and SIC contents, \uffce\uffb4 13 C SOC and \uffce\uffb4 13 C SIC and detect mixes of carbonate with different origin on a non\uffe2\uff80\uff90pretreated aliquot. Development is needed (i) on more soil and carbonate samples and (ii) to improve the precision and accuracy of the RE\uffe2\uff80\uff90Picarro setup. Microbial transformation of soil organic matter plays a critical role in carbon (C) cycling making it essential to understand how land use and management practices influence microbial physiology and its connection to C dynamics. One factor that is likely to impact soil microbial physiology is crop diversification via its influence on belowground diversity (e.g., chemical heterogeneity of C inputs, microbial community composition). However, the effect of crop diversification measures on microbial physiology and potential effects on C cycling in agricultural soils is still unclear. To address this knowledge gap, we sampled topsoil from eight experimental sites covering different crop diversification measures across Europe (i.e., cover crops, ley farming, vegetation stripes). We used the 18O\uffe2\uff80\uff90labelling method to analyse microbial C use efficiency (CUE), growth, respiration and biomass C. Additionally, a second sampling at five selected sites examined whether the growing season influenced the impact of crop diversification. Meta\uffe2\uff80\uff90analysis revealed no overall effect of crop diversification on CUE, microbial activity, biomass or soil organic C (SOC). However, the effects varied with the type of diversification measure: cover crops did not affect carbon processing, vegetation stripes increased microbial activity, and ley farming enhanced CUE. The largest variation in CUE was observed between samplings at the same sites, indicating seasonal dynamics. Temperature, precipitation and photosynthetically active radiation predicted seasonal variation in CUE (R2\uffe2\uff80\uff89=\uffe2\uff80\uff890.36). While cover crops did not significantly impact C storage in our study, both ley farming and vegetation stripes increased SOC. The overall effect of crop diversification on SOC seems to be decoupled from highly temporally variable CUE in the bulk soil and rather relate to C\uffe2\uff80\uff90inputs.Human activities have greatly increased the availability of biologically active forms of nutrients [e.g., nitrogen (N), phosphorous (P), potassium (K), magnesium (Mg)] in many soil ecosystems worldwide. Multi\uffe2\uff80\uff90nutrient fertilization strongly increases plant productivity but may also alter the storage of carbon (C) in soil, which represents the largest terrestrial pool of organic C. Despite this issue is important from a global change perspective, key questions remain on how the single addition of N or the combination of N with other nutrients might affect C sequestration in human\uffe2\uff80\uff90managed soils. Here, we use a 19\uffe2\uff80\uff90year old nutrient addition experiment on a permanent grassland to test for nutrient\uffe2\uff80\uff90induced effects on soil C sequestration. We show that combined NPKMg additions to permanent grassland have \uffe2\uff80\uff98constrained\uffe2\uff80\uff99 soil C sequestration to levels similar to unfertilized plots whereas the single addition of N significantly enhanced soil C stocks (N\uffe2\uff80\uff90only fertilized soils store, on average, 11\uffc2\uffa0t C\uffc2\uffa0ha\uffe2\uff88\uff921 more than unfertilized soils). These results were consistent across grazing and liming treatments suggesting that whilst multi\uffe2\uff80\uff90nutrient additions increase plant productivity, soil C sequestration is increased by N\uffe2\uff80\uff90only additions. The positive N\uffe2\uff80\uff90only effect on soil C content was not related to changes in plant species diversity or to the functional composition of the plant community. N\uffe2\uff80\uff90only fertilized grasslands show, however, increases in total root mass and the accumulation of organic matter detritus in topsoils. Finally, soils receiving any N addition (N only or N in combination with other nutrients) were associated with high N losses. Overall, our results demonstrate that nutrient fertilization remains an important global change driver of ecosystem functioning, which can strongly affect the long\uffe2\uff80\uff90term sustainability of grassland soil ecosystems (e.g., soils ability to deliver multiple ecosystem services).

Stabilising and reversing the loss of organic matter from cropland soils is a challenge for all nations to meet the United Nations Sustainable Development Goals. Sustainable land management (SLM) has been promoted as a mechanism of achieving this, but to date, there is no evidence of positive impacts at scale. Here we show the first signs of the reversal of soil carbon loss in cultivated topsoils in Great Britain, following a period of reported SLM uptake, using 40+ years of national soil monitoring from the UKCEH Countryside Survey. Following a prolonged historic decline at rates of \uffe2\uff88\uff920.16\uffe2\uff80\uff89t\uffe2\uff80\uff89ha \uffe2\uff88\uff921 \uffe2\uff80\uff89year \uffe2\uff88\uff921 , there was a significant increase in cropland topsoil SOC stocks (0\uffe2\uff80\uff9315\uffe2\uff80\uff89cm) from 2007 to 2019\uffe2\uff80\uff9322 with an accrual rate of 0.17\uffe2\uff80\uff89t\uffe2\uff80\uff89ha \uffe2\uff88\uff921 \uffe2\uff80\uff89year \uffe2\uff88\uff921 , approximately 0.74\uffe2\uff80\uff89MtC\uffe2\uff80\uff89year \uffe2\uff88\uff921 nationally. We discuss reported management shifts in Great Britain in the corresponding period and identify a reduction in conventional tillage and reduced straw removal as potential drivers, but highlight additional evidence gaps worthy of consideration. This increase in topsoil SOC may represent net carbon sequestration or carbon redistribution (geographic or vertical) but nevertheless demonstrates that topsoil properties can be restored at scale and offers hope that a concerted effort by land managers can halt, and potentially reverse, SOC loss from cropland soils. Biodiversity loss, an important consequence of agricultural intensification, can lead to reductions in agroecosystem functions and services. Increasing crop diversity through rotation may alleviate these negative consequences by restoring positive aboveground\uffe2\uff80\uff93belowground interactions. Positive impacts of aboveground biodiversity on belowground communities and processes have primarily been observed in natural systems. Here, we test for the effects of increased diversity in an agroecosystem, where plant diversity is increased over time through crop rotation. As crop diversity increased from one to five species, distinct soil microbial communities were related to increases in soil aggregation, organic carbon, total nitrogen, microbial activity and decreases in the carbon\uffe2\uff80\uff90to\uffe2\uff80\uff90nitrogen acquiring enzyme activity ratio. This study indicates positive biodiversity\uffe2\uff80\uff93function relationships in agroecosystems, driven by interactions between rotational and microbial diversity. By increasing the quantity, quality and chemical diversity of residues, high diversity rotations can sustain soil biological communities, with positive effects on soil organic matter and soil fertility.

Here, we aimed to develop an open access framework to downscale soil property maps using remote and proximal sensor data and test it for predicting soil organic carbon (SOC) and clay across different regions of Europe. To facilitate the dissemination of this framework, we developed the R package \uffe2\uff80\uff9c soilscaler \uffe2\uff80\uff9d, which contains integrated functions for producing downscaled soil maps. This approach uses coarse resolution maps as a baseline, incorporating sensor data and soil observations to train a model explaining local variation of soil properties. We tested the framework in Denmark, Northern Ireland, Lithuania, The Netherlands, and Turkey. For comparison, we also created high\uffe2\uff80\uff90resolution maps using a conventional digital soil mapping (DSM) approach for each field independently. We found that the downscaling performance depends on the quality of the coarse\uffe2\uff80\uff90resolution soil maps, the spatial variability of soil properties within a given field, and the range of inter\uffe2\uff80\uff90field variations in each country. Although the downscaling process showed lower performance than the conventional DSM approach, the results indicate that the downscaled maps better represent local variability than existing national and global soil maps. Additionally, we found that remote sensing sensors generally better represent the spatial distribution of SOC, while proximal soil sensors better capture clay contents. Future studies should focus on gathering more sensor data and correlating it with soil properties to improve predictions based solely on sensor data. It is unclear how elevated CO2 (eCO2) and the corresponding shifts in temperature and precipitation will interact to impact ecosystems over time. During a 7\uffe2\uff80\uff90year experiment in a semi\uffe2\uff80\uff90arid grassland, the response of plant biomass to eCO2 and warming was largely regulated by interannual precipitation, while the response of plant community composition was more sensitive to experiment duration. The combined effects of eCO2 and warming on aboveground plant biomass were less positive in \uffe2\uff80\uff98wet\uffe2\uff80\uff99 growing seasons, but total plant biomass was consistently stimulated by ~\uffc2\uffa025% due to unique, supra\uffe2\uff80\uff90additive responses of roots. Independent of precipitation, the combined effects of eCO2 and warming on C3 graminoids became increasingly positive and supra\uffe2\uff80\uff90additive over time, reversing an initial shift toward C4 grasses. Soil resources also responded dynamically and non\uffe2\uff80\uff90additively to eCO2 and warming, shaping the plant responses. Our results suggest grasslands are poised for drastic changes in function and highlight the need for long\uffe2\uff80\uff90term, factorial experiments.

We collected soils from 59 dryland ecosystems worldwide to investigate the importance of microbial communities as predictor of multifunctionality resistance to climate change and nitrogen fertilisation. Multifunctionality had a lower resistance to wetting\uffe2\uff80\uff93drying cycles than to warming or N deposition. Multifunctionality resistance was regulated by changes in microbial composition (relative abundance of phylotypes) but not by richness, total abundance of fungi and bacteria or the fungal: bacterial ratio. Our results suggest that positive effects of particular microbial taxa on multifunctionality resistance could potentially be controlled by altering soil pH. Together, our work demonstrates strong links between microbial community composition and multifunctionality resistance in dryland soils from six continents, and provides insights into the importance of microbial community composition for buffering effects of global change in drylands worldwide.The net balance of greenhouse gas (GHG) exchanges between terrestrial ecosystems and the atmosphere under elevated atmospheric carbon dioxide (CO2) remains poorly understood. Here, we synthesise 1655 measurements from 169 published studies to assess GHGs budget of terrestrial ecosystems under elevated CO2. We show that elevated CO2 significantly stimulates plant C pool (NPP) by 20%, soil CO2 fluxes by 24%, and methane (CH4) fluxes by 34% from rice paddies and by 12% from natural wetlands, while it slightly decreases CH4 uptake of upland soils by 3.8%. Elevated CO2 causes insignificant increases in soil nitrous oxide (N2O) fluxes (4.6%), soil organic C (4.3%) and N (3.6%) pools. The elevated CO2\uffe2\uff80\uff90induced increase in GHG emissions may decline with CO2 enrichment levels. An elevated CO2\uffe2\uff80\uff90induced rise in soil CH4 and N2O emissions (2.76 Pg CO2\uffe2\uff80\uff90equivalent year\uffe2\uff88\uff921) could negate soil C enrichment (2.42 Pg CO2 year\uffe2\uff88\uff921) or reduce mitigation potential of terrestrial net ecosystem production by as much as 69% (NEP, 3.99 Pg CO2 year\uffe2\uff88\uff921) under elevated CO2. Our analysis highlights that the capacity of terrestrial ecosystems to act as a sink to slow climate warming under elevated CO2 might have been largely offset by its induced increases in soil GHGs source strength.

For this, we collected and analysed 435 topsoil samples (0\uffe2\uff80\uff9310\uffc2\uffa0cm) from 87 locations. We showed that high levels of topsoil element coupling, defined as the average correlation among nineteen soil elements, are maintained over geological timescales globally. Cross\uffe2\uff80\uff90biome changes in plant biodiversity, soil microbial structure, weathering, soil pH and texture, and mineral\uffe2\uff80\uff90free unprotected organic matter content largely controlled multi\uffe2\uff80\uff90element coupling.

However, it remains unexplored how they modify the niche differences that stabilise species coexistence and the average fitness differences driving competitive dominance. We conducted a field study in Mediterranean annual grasslands to parameterise population models of six competing plant species. Spatially explicit floral visitor assemblages and soil salinity variation were characterized for each species. Both floral visitors and soil salinity modified species population dynamics via direct changes in seed production and indirect changes in competitive responses. Although the magnitude and sign of these changes were species specific, floral visitors promoted coexistence at neighbourhood scales while soil salinity did so over larger scales by changing the superior competitor's identity. Our results show how below and aboveground interactions maintain diversity in heterogeneous landscapes through their opposing effects on the determinants of competitive outcomes.

This study employs the DEMENT model of microbial decomposition, along with empirical mutation and dispersal rates, to explore the roles of mutation and dispersal in the adaptation of soil microbial populations to shifts in litter chemistry, changes that are anticipated with climate\uffe2\uff80\uff90driven vegetation dynamics. Following a change in litter chemistry, mutation generally allows for a higher rate of litter decomposition than dispersal, especially when dispersal predominantly introduces genotypes already present in the population. These findings challenge the common idea that mutation rates are too low to affect ecosystem processes on ecological timescales. These results demonstrate that evolutionary processes, such as mutation, can help maintain ecosystem functioning as the climate changes.Soils of grasslands represent a large potential reservoir for storingCO2, but this potential likely depends on how grasslands are managed for large mammal grazing. Previous studies found both strong positive and negative grazing effects on soil organic carbon (SOC) but explanations for this variation are poorly developed. Expanding on previous reviews, we performed a multifactorial meta\uffe2\uff80\uff90analysis of grazer effects onSOCdensity on 47 independent experimental contrasts from 17 studies. We explicitly tested hypotheses that grazer effects would shift from negative to positive with decreasing precipitation, increasing fineness of soil texture, transition from dominant grass species with C3to C4photosynthesis, and decreasing grazing intensity, after controlling for study duration and sampling depth. The six variables of soil texture, precipitation, grass type, grazing intensity, study duration, and sampling depth explained 85% of a large variation (\uffc2\uffb1150\uffc2\uffa0g\uffc2\uffa0m\uffe2\uff88\uff922\uffc2\uffa0yr\uffe2\uff88\uff921) in grazing effects, and the best model included significant interactions between precipitation and soil texture (P\uffc2\uffa0=\uffc2\uffa00.002), grass type, and grazing intensity (P\uffc2\uffa0=\uffc2\uffa00.012), and study duration and soil sampling depth (P\uffc2\uffa0=\uffc2\uffa00.020). Specifically, an increase in mean annual precipitation of 600\uffc2\uffa0mm resulted in a 24%decreasein grazer effect size on finer textured soils, while on sandy soils the same increase in precipitation produced a 22%increasein grazer effect onSOC. Increasing grazing intensity increasedSOCby 6\uffe2\uff80\uff937% on C4\uffe2\uff80\uff90dominated and C4\uffe2\uff80\uff93C3mixed grasslands, but decreasedSOCby an average 18% in C3\uffe2\uff80\uff90dominated grasslands. We discovered these patterns despite a lack of studies in natural, wildlife\uffe2\uff80\uff90dominated ecosystems, and tropical grasslands. Our results, which suggest a future focus on why C3vs. C4\uffe2\uff80\uff90dominated grasslands differ so strongly in their response ofSOCto grazing, show that grazer effects onSOCare highly context\uffe2\uff80\uff90specific and imply that grazers in different regions might be managed differently to help mitigate greenhouse gas emissions.

The altered morphological and physiological traits of the roots exposed to experimental warming could be responsible for this variation in root exudation.

In contrast, the trees exposed to both experimental warming and N fertilization did not show increased exudation rates or soil enzyme activity, indicating that the stimulatory effects of experimental warming on root exudation depend on soil fertility. Collectively, our results provide preliminary evidence that an increase in the release of root exudates into the soil may be an important physiological adjustment by which the sustained growth responses of plants to experimental warming may be maintained via enhanced soil microbial activity and soil N transformation. Accordingly, the underlying mechanisms by which plant root\uffe2\uff80\uff90microbe interactions influence soil organic matter decomposition and N cycling should be incorporated into climate\uffe2\uff80\uff90carbon cycle models to determine reliable estimates of long\uffe2\uff80\uff90term C storage in forests.

Urban grasslands are expanding rapidly along with urbanization, which is expected to increase at unprecedented rates in upcoming decades. The large and increasing area of urban grasslands and their impact on water and air quality justify the need for a better understanding of their biogeochemical cycles. There is also great uncertainty about the effect that climate change, especially changes in winter snow cover, will have on nutrient cycles in urban grasslands. We aimed to evaluate how reduced snow accumulation directly affects winter soil frost dynamics, and indirectly greenhouse gas fluxes and the processing of carbon (C) and nitrogen (N) during the subsequent growing season in northern urban grasslands. Both artificial and natural snow reduction increased winter soil frost, affecting winter microbial C and N processing, accelerating C and N cycles and increasing soil\uffc2\uffa0:\uffc2\uffa0atmosphere greenhouse gas exchange during the subsequent growing season. With lower snow accumulations that are predicted with climate change, we found decreases in N retention in these ecosystems, and increases inN2OandCO2flux to the atmosphere, significantly increasing the global warming potential of urban grasslands. Our results suggest that the environmental impacts of these rapidly expanding ecosystems are likely to increase as climate change brings milder winters and more extensive soil frost.

We studied the interactive effects of C and N on SOM mineralization (by natural 13C labelling adding C4\uffe2\uff80\uff90sucrose or C4\uffe2\uff80\uff90maize straw to C3\uffe2\uff80\uff90soil) in relation to microbial growth kinetics and to the activities of five hydrolytic enzymes. This encompasses the groups of parameters governing two mechanisms of priming effects \uffe2\uff80\uff93 microbial N mining and stoichiometric decomposition theories. In sole C treatments, positive PE was accompanied by a decrease in specific microbial growth rates, confirming a greater contribution of K\uffe2\uff80\uff90strategists to the decomposition of native SOM. Sucrose addition with N significantly accelerated mineralization of native SOM, whereas mineral N added with plant residues accelerated decomposition of plant residues. This supports the microbial mining theory in terms of N limitation. Sucrose addition with N was accompanied by accelerated microbial growth, increased activities of \uffce\uffb2\uffe2\uff80\uff90glucosidase and cellobiohydrolase, and decreased activities of xylanase and leucine amino peptidase. This indicated an increased contribution of r\uffe2\uff80\uff90strategists to the PE and to decomposition of cellulose but the decreased hemicellulolytic and proteolytic activities. Thus, the acceleration of the C cycle was primed by exogenous organic C and was controlled by N. This confirms the stoichiometric decomposition theory. Both K\uffe2\uff80\uff90 and r\uffe2\uff80\uff90strategists were beneficial for priming effects, with an increasing contribution of K\uffe2\uff80\uff90selected species under N limitation. Thus, the priming phenomenon described in \uffe2\uff80\uff98microbial N mining\uffe2\uff80\uff99 theory can be ascribed to K\uffe2\uff80\uff90strategists. In contrast, \uffe2\uff80\uff98stoichiometric decomposition\uffe2\uff80\uff99 theory, that is, accelerated OM mineralization due to balanced microbial growth, is explained by domination of r\uffe2\uff80\uff90strategists.

Since snow insulates soil, a decreased snow pack can increase the frequency of soil freezing, which has been shown to have important biogeochemical implications. One of the most notable effects of soil freezing is increased inorganic nitrogen losses from soil during the following growing season. Decreased nitrogen retention is thought to be due to reduced root uptake, but has not yet been measured directly. We conducted a 2\uffe2\uff80\uff90year snow\uffe2\uff80\uff90removal experiment at Hubbard Brook Experimental Forest in New Hampshire, USA to determine the effects of soil freezing on root uptake and leaching of inorganic nitrogen simultaneously. Snow removal significantly increased the depth of maximal soil frost by 37.2 and 39.5\uffc2\uffa0cm in the first and second winters, respectively (P\uffc2\uffa0<\uffc2\uffa00.001 in 2008/2009 and 2009/2010). As a consequence of soil freezing, root uptake of ammonium declined significantly during the first and second growing seasons after snow removal (P\uffc2\uffa0=\uffc2\uffa00.023 for 2009 and P\uffc2\uffa0=\uffc2\uffa00.005 for 2010). These observed reductions in root nitrogen uptake coincided with significant increases in soil solution concentrations of ammonium in the Oa horizon (P\uffc2\uffa0=\uffc2\uffa00.001 for 2009 and 2010) and nitrate in the B horizon (P\uffc2\uffa0<\uffc2\uffa00.001 and P\uffc2\uffa0=\uffc2\uffa00.003 for 2009 and 2010, respectively).

Results of this study provide direct evidence that soil freezing reduces root nitrogen uptake, demonstrating that the effects of winter climate change on root function has significant consequences for nitrogen retention and loss in forest ecosystems.

However, this region has not been well represented in previous large\uffe2\uff80\uff90scale syntheses of land\uffe2\uff80\uff90use change effects onSOC, especially regarding effects of afforestation. Therefore, we conducted a meta\uffe2\uff80\uff90analysis ofSOCstock change following afforestation in Northern Europe. Response ratios were calculated for forest floors and mineral soils (0\uffe2\uff80\uff9310\uffc2\uffa0cm and 0\uffe2\uff80\uff9320/30\uffc2\uffa0cm layers) based on paired control (former land use) and afforested plots. We analyzed the influence of forest age, former land\uffe2\uff80\uff90use, forest type, and soil textural class. Three major improvements were incorporated in the meta\uffe2\uff80\uff90analysis: analysis of major interaction groups, evaluation of the influence of nonindependence between samples according to study design, and mass correction. Former land use was a major factor contributing to changes inSOCafter afforestation. In former croplands,SOCchange differed between soil layers and was significantly positive (20%) in the 0\uffe2\uff80\uff9310\uffc2\uffa0cm layer. Afforestation of former grasslands had a small negative (nonsignificant) effect indicating limitedSOCchange following this land\uffe2\uff80\uff90use change within the region. Forest floors enhanced the positive effects of afforestation onSOC, especially with conifers. Meta\uffe2\uff80\uff90estimates calculated for the periods <30\uffc2\uffa0years and >30\uffc2\uffa0years since afforestation revealed a shift from initial loss to later gain ofSOC. The interaction group analysis indicated that meta\uffe2\uff80\uff90estimates in former land\uffe2\uff80\uff90use, forest type, and soil textural class alone were either offset or enhanced when confounding effects among variable classes were considered. Furthermore, effect sizes were slightly overestimated if sample dependence was not accounted for and if no mass correction was performed. We conclude that significantSOCsequestration in Northern Europe occurs after afforestation of croplands and not grasslands, and changes are small within a 30\uffe2\uff80\uff90year perspective.

A mean 26.7% enhancement of ozone concentration above the ambient level (A\uffe2\uff80\uff90O3) significantly reduced CH4 emission at tillering and flowering stages leading to a reduction of seasonal integral CH4 emission by 29.6% on average across the two cultivars. The reduced CH4 emission is associated with O3\uffe2\uff80\uff90induced reduction in the whole\uffe2\uff80\uff90plant biomass (\uffe2\uff88\uff9213.2%), root biomass (\uffe2\uff88\uff9234.7%), and maximum tiller number (\uffe2\uff88\uff9210.3%), all of which curbed the carbon supply for belowground CH4 production and its release from submerged soil to atmosphere. Although no significant difference was detected between the cultivars in the CH4 emission response to E\uffe2\uff80\uff90O3, a larger decrease in CH4 emission with IIY084 (\uffe2\uff88\uff9233.2%) than that with YD6 (\uffe2\uff88\uff927.0%) was observed at tillering stage, which may be due to the larger reduction in tiller number in IIY084 by E\uffe2\uff80\uff90O3. Additionally, E\uffe2\uff80\uff90O3 reduced seasonal mean NOx flux by 5.7% and 11.8% with IIY084 and YD6, respectively, but the effects were not significant statistically. We found that the relative response of CH4 emission to E\uffe2\uff80\uff90O3 was not significantly different from those reported in open\uffe2\uff80\uff90top chamber experiments. This study has thus confirmed that increasing ozone concentration would mitigate the global warming potential of CH4 and suggested consideration of the feedback mechanism between ozone and its precursor emission into the projection of future ozone effects on terrestrial ecosystem.

However, little is known about how plant community structure regulates responses of soil respiration to climate change. Here, we used a 13\uffe2\uff80\uff90year field warming experiment to explore the mechanisms underlying plant community regulation on feedbacks of soil respiration to climate change in a tallgrass prairie in Oklahoma, USA. Infrared heaters were used to elevate temperature about 2\uffc2\uffa0\uffc2\uffb0C since November 1999. Annual clipping was used to mimic hay harvest. Our results showed that experimental warming significantly increased soil respiration approximately from 10% in the first 7\uffc2\uffa0years (2000\uffe2\uff80\uff932006) to 30% in the next 6\uffc2\uffa0years (2007\uffe2\uff80\uff932012). The two\uffe2\uff80\uff90stage warming stimulation of soil respiration was closely related to warming\uffe2\uff80\uff90induced increases in ecosystem production over the years. Moreover, we found that across the 13\uffc2\uffa0years, warming\uffe2\uff80\uff90induced increases in soil respiration were positively affected by the proportion of aboveground net primary production (ANPP) contributed by C3 forbs. Functional composition of the plant community regulated warming\uffe2\uff80\uff90induced increases in soil respiration through the quantity and quality of organic matter inputs to soil and the amount of photosynthetic carbon (C) allocated belowground. Clipping, the interaction of clipping with warming, and warming\uffe2\uff80\uff90induced changes in soil temperature and moisture all had little effect on soil respiration over the years (all P\uffc2\uffa0>\uffc2\uffa00.05). Our results suggest that climate warming may drive an increase in soil respiration through altering composition of plant communities in grassland ecosystems.

Solar UVB radiation was manipulated using transparent plastic filter films to create a near\uffe2\uff80\uff90ambient (90% of ambient UVB) or a reduced solar UVB treatment (15% of ambient UVB). The warming treatment was imposed passively by wrapping the same filter material around the plots resulting in a mean air and soil temperature increase of about 1.2\uffe2\uff80\uff83\uffc2\uffb0C. Aboveground plant production was not affected by warming, and marginally reduced at near\uffe2\uff80\uff90ambient UVB only in the second season.

In soil fractions, only isotope compositions of short\uffe2\uff80\uff90chain FAs (C16+18) were affected. Fractions of \uffe2\uff80\uff98new\uffe2\uff80\uff99 (experimental\uffe2\uff80\uff90derived) FAs were calculated using isotope depletion in elevated CO2 plots and decreased from free light to fine mineral fractions. \uffe2\uff80\uff98New\uffe2\uff80\uff99 FAs were higher in short\uffe2\uff80\uff90chain compared to long\uffe2\uff80\uff90chain FAs (C20\uffe2\uff88\uff9230), indicating a faster turnover of short\uffe2\uff80\uff90chain compared to long\uffe2\uff80\uff90chain FAs. Increased N deposition did not significantly affect the quantity of \uffe2\uff80\uff98new\uffe2\uff80\uff99 FAs in soil fractions, but showed a tendency of increased amounts of \uffe2\uff80\uff98old\uffe2\uff80\uff99 (pre\uffe2\uff80\uff90experimental) C suggesting that decomposition of \uffe2\uff80\uff98old\uffe2\uff80\uff99 C is retarded by high N inputs.

However, during 40\uffc2\uffa0years of study of reforestation in the subtropical southeastern USA, repeated observations of above\uffe2\uff80\uff90 and belowground carbon documented that significant gains in soil organic matter (SOM) in surface soils (0\uffe2\uff80\uff937.5\uffc2\uffa0cm) were offset by significant SOM losses in subsoils (35\uffe2\uff80\uff9360\uffc2\uffa0cm). Here, we extended the observation period in this long\uffe2\uff80\uff90term experiment by an additional decade, and used soil fractionation and stable isotopes and radioisotopes to explore changes in soil organic carbon and soil nitrogen that accompanied nearly 50\uffc2\uffa0years of loblolly pine secondary forest development. We observed that accumulations of mineral soil C and N from 0 to 7.5\uffc2\uffa0cm were almost entirely due to accumulations of light\uffe2\uff80\uff90fraction SOM. Meanwhile, losses of soil C and N from mineral soils at 35 to 60\uffc2\uffa0cm were from SOM associated with silt and clay\uffe2\uff80\uff90sized particles. Isotopic signatures showed relatively large accumulations of forest\uffe2\uff80\uff90derived carbon in surface soils, and little to no accumulation of forest\uffe2\uff80\uff90derived carbon in subsoils. We argue that the land use change from old field to secondary forest drove biogeochemical and hydrological changes throughout the soil profile that enhanced microbial activity and SOM decomposition in subsoils. However, when the pine stands aged and began to transition to mixed pines and hardwoods, demands on soil organic matter for nutrients to support aboveground growth eased due to pine mortality, and subsoil organic matter levels stabilized. This study emphasizes the importance of long\uffe2\uff80\uff90term experiments and deep measurements when characterizing soil C and N responses to land use change and the remarkable paucity of such long\uffe2\uff80\uff90term soil data deeper than 30\uffc2\uffa0cm.

We show, using a long\uffe2\uff80\uff90term factorial experiment, that plant diversity loss alters the effects of warming on productivity. Aboveground primary productivity was increased by both high plant diversity and warming, and, in concert, warming (\uffe2\uff89\uff881.5\uffc2\uffa0\uffc2\uffb0C average above and belowground warming over the growing season) and diversity caused a greater than additive increase in aboveground productivity. The aboveground warming effects increased over time, particularly at higher levels of diversity, perhaps because of warming\uffe2\uff80\uff90induced increases in legume and C4 bunch grass abundances, and facilitative feedbacks of these species on productivity. Moreover, higher plant diversity was associated with the amelioration of warming\uffe2\uff80\uff90induced environmental conditions. This led to cooler temperatures, decreased vapor pressure deficit, and increased surface soil moisture in higher diversity communities. Root biomass (0\uffe2\uff80\uff9330\uffc2\uffa0cm) was likewise consistently greater at higher plant diversity and was greater with warming in monocultures and at intermediate diversity, but at high diversity warming had no detectable effect. This may be because warming increased the abundance of legumes, which have lower root\uffc2\uffa0:\uffc2\uffa0shoot ratios than the other types of plants. In addition, legumes increase soil nitrogen (N) supply, which could make N less limiting to other species and potentially decrease their investment in roots. The negative warming\uffc2\uffa0\uffc3\uff97\uffc2\uffa0diversity interaction on root mass led to an overall negative interactive effect of these two global change factors on the sum of above and belowground biomass, and thus likely on total plant carbon stores. In total, plant diversity increased the effect of warming on aboveground net productivity and moderated the effect on root mass. These divergent effects suggest that warming and changes in plant diversity are likely to have both interactive and divergent impacts on various aspects of ecosystem functioning.

In the first 3\uffc2\uffa0years (2004\uffe2\uff80\uff932006), lower CH4 emissions in the treatment plots relative to the control coincided with delayed soil temperature increase in the treatment plots at the beginning of the growing season (May). After 11 treatment years (in 2014), CH4 emissions were lower in the treatment plots relative to the control over the entire growing season, resulting in a reduction in total growing season CH4 emission by 27%. From May to July 2014, reduced sedge leaf area coincided with lower CH4 emissions in the treatment plots compared to the control. From July to August, lower dissolved organic carbon concentrations in the pore water of the treatment plots explained 72% of the differences in CH4 emission between control and treatment. In addition, greater Sphagnum moss growth in the treatment plots resulted in a larger distance between the moss surface and the water table (i.e., increasing the oxic layer) which may have enhanced the CH4 oxidation potential in the treatment plots relative to the control in 2014. The differences in vegetation might also explain the lower temperature sensitivity of CH4 emission observed in the treatment plots relative to the control. Overall, this study suggests that greater soil frost, associated with future winter climate change, might substantially reduce the growing season CH4 emission in boreal peatlands through altering vegetation dynamics and subsequently causing vegetation\uffe2\uff80\uff90mediated effects on CH4 exchange.

In this study, we performed a comprehensive meta\uffe2\uff80\uff90analysis of 115 published studies to examine the responses of 19 variables associated with belowground C and N cycling to livestock grazing in global grasslands. Our results showed that, on average, grazing significantly decreased belowground C and N pools in grassland ecosystems, with the largest decreases in microbial biomass C and N (21.62% and 24.40%, respectively). In contrast, belowground fluxes, including soil respiration, soil net N mineralization and soil N nitrification increased by 4.25%, 34.67% and 25.87%, respectively, in grazed grasslands compared to ungrazed ones.

Here, we show in a series of experiments that high\uffe2\uff80\uff90yielding rice cultivars actually reduce CH4 emissions from typical paddy soils. Averaged across 33 rice cultivars, a biomass increase of 10% resulted in a 10.3% decrease in CH4 emissions in a soil with a high carbon (C) content.

Our results were further supported by a meta\uffe2\uff80\uff90analysis, showing that high\uffe2\uff80\uff90yielding rice cultivars strongly decrease CH4 emissions from paddy soils with high organic C contents. Based on our results, increasing rice biomass by 10% could reduce annual CH4 emissions from Chinese rice agriculture by 7.1%.

Here, we report on two separate regional and continental empirical studies, including >500 locations, aiming to identify the relative importance of climatic legacies (climatic anomaly over the last 20,000\uffc2\uffa0years) compared to current climates in predicting the relative abundance of ecological clusters formed by species strongly co\uffe2\uff80\uff90occurring within two independent above\uffe2\uff80\uff90 and belowground networks. Climatic legacies explained a significant portion of the variation in the current community assembly of terrestrial ecosystems (up to 15.4%) that could not be accounted for by current climate, soil properties, and management. Changes in the relative abundance of ecological clusters linked to climatic legacies (e.g., past temperature) showed the potential to indirectly alter other clusters, suggesting cascading effects. Our work illustrates the role of climatic legacies in regulating ecosystem community assembly and provides further insights into possible winner and loser community assemblies under global change scenarios.A positive soil carbon (C)\uffe2\uff80\uff90climate feedback is embedded into the climatic models of the IPCC. However, recent global syntheses indicate that the temperature sensitivity of soil respiration (RS) in drylands, the largest biome on Earth, is actually lower in warmed than in control plots. Consequently, soil C losses with future warming are expected to be low compared with other biomes. Nevertheless, the empirical basis for these global extrapolations is still poor in drylands, due to the low number of field experiments testing the pathways behind the long\uffe2\uff80\uff90term responses of soil respiration (RS) to warming. Importantly, global drylands are covered with biocrusts (communities formed by bryophytes, lichens, cyanobacteria, fungi, and bacteria), and thus,RSresponses to warming may be driven by both autotrophic and heterotrophic pathways. Here, we evaluated the effects of 8\uffe2\uff80\uff90year experimental warming onRS, and the different pathways involved, in a biocrust\uffe2\uff80\uff90dominated dryland in southern Spain. We also assessed the overall impacts on soil organic C (SOC) accumulation over time. Across the years and biocrust cover levels, warming reducedRSby 0.30\uffc2\uffa0\uffce\uffbcmol\uffc2\uffa0CO2\uffc2\uffa0m\uffe2\uff88\uff922\uffc2\uffa0s\uffe2\uff88\uff921(95% CI\uffc2\uffa0=\uffc2\uffa0\uffe2\uff88\uff920.24 to 0.84), although the negative warming effects were only significant after 3\uffc2\uffa0years of elevated temperatures in areas with low initial biocrust cover. We found support for different pathways regulating the warming\uffe2\uff80\uff90induced reduction inRSat areas with low (microbial thermal acclimation via reduced soil mass\uffe2\uff80\uff90specific respiration and \uffce\uffb2\uffe2\uff80\uff90glucosidase enzymatic activity) vs. high (microbial thermal acclimation jointly with a reduction in autotrophic respiration from decreased lichen cover) initial biocrust cover. Our 8\uffe2\uff80\uff90year experimental study shows a reduction in soil respiration with warming and highlights that biocrusts should be explicitly included in modeling efforts aimed to quantify the soil C\uffe2\uff80\uff93climate feedback in drylands.Rising levels of atmospheric CO2 frequently stimulate plant inputs to soil, but the consequences of these changes for soil carbon (C) dynamics are poorly understood. Plant\uffe2\uff80\uff90derived inputs can accumulate in the soil and become part of the soil C pool (\uffe2\uff80\uff9cnew soil C\uffe2\uff80\uff9d), or accelerate losses of pre\uffe2\uff80\uff90existing (\uffe2\uff80\uff9cold\uffe2\uff80\uff9d) soil C. The dynamics of the new and old pools will likely differ and alter the long\uffe2\uff80\uff90term fate of soil C, but these separate pools, which can be distinguished through isotopic labeling, have not been considered in past syntheses. Using meta\uffe2\uff80\uff90analysis, we found that while elevated CO2 (ranging from 550 to 800 parts per million by volume) stimulates the accumulation of new soil C in the short term (<1\uffc2\uffa0year), these effects do not persist in the longer term (1\uffe2\uff80\uff934\uffc2\uffa0years). Elevated CO2 does not affect the decomposition or the size of the old soil C pool over either temporal scale. Our results are inconsistent with predictions of conventional soil C models and suggest that elevated CO2 might increase turnover rates of new soil C. Because increased turnover rates of new soil C limit the potential for additional soil C sequestration, the capacity of land ecosystems to slow the rise in atmospheric CO2 concentrations may be smaller than previously assumed.

Most plastics arriving in the oceans were produced, used, and often disposed on land. Hence, it is within terrestrial systems that microplastics might first interact with biota eliciting ecologically relevant impacts. This article introduces the pervasive microplastic contamination as a potential agent of global change in terrestrial systems, highlights the physical and chemical nature of the respective observed effects, and discusses the broad toxicity of nanoplastics derived from plastic breakdown. Making relevant links to the fate of microplastics in aquatic continental systems, we here present new insights into the mechanisms of impacts on terrestrial geochemistry, the biophysical environment, and ecotoxicology. Broad changes in continental environments are possible even in particle\uffe2\uff80\uff90rich habitats such as soils. Furthermore, there is a growing body of evidence indicating that microplastics interact with terrestrial organisms that mediate essential ecosystem services and functions, such as soil dwelling invertebrates, terrestrial fungi, and plant\uffe2\uff80\uff90pollinators. Therefore, research is needed to clarify the terrestrial fate and effects of microplastics.

We explored the effect of long\uffe2\uff80\uff90term N and NPK fertilization on soil bacterial diversity and community composition using meta\uffe2\uff80\uff90analysis of a global dataset. Nitrogen fertilization decreased soil pH, and increased soil organic carbon (C) and available N contents. Bacterial taxonomic diversity was decreased by N fertilization alone, but was increased by NPK fertilization. The effect of N fertilization on bacterial diversity varied with soil texture and water management, but was independent of crop type or N application rate. Changes in bacterial diversity were positively related to both soil pH and organic C content under N fertilization alone, but only to soil organic C under NPK fertilization. Microbial biomass C decreased with decreasing bacterial diversity under long\uffe2\uff80\uff90term N fertilization. Nitrogen fertilization increased the relative abundance of Proteobacteria and Actinobacteria, but reduced the abundance of Acidobacteria, consistent with the general life history strategy theory for bacteria.

Recent research has incorporated dynamic permafrost thaw in Earth system models (ESMs) and indicates that Arctic tundra could be a significant future carbon (C) source due to the enhanced decomposition of thawed deep soil C. However, warming\uffe2\uff80\uff90induced biotic changes may influence biologically related parameters and the consequent projections inESMs. How model parameters associated with biotic responses will change under warming and to what extent these changes affect projected C budgets have not been carefully examined. In this study, we synthesized six data sets over 5\uffc2\uffa0years from a soil warming experiment at the Eight Mile Lake, Alaska, into the TerrestrialECOsystem (TECO) model with a probabilistic inversion approach. TheTECOmodel used multiple soil layers to track dynamics of thawed soil under different treatments. Our results show that warming increased light use efficiency of vegetation photosynthesis but decreased baseline (i.e., environment\uffe2\uff80\uff90corrected) turnover rates ofSOCin both the fast and slow pools in comparison with those under control. Moreover, the parameter changes generally amplified over time, suggesting processes of gradual physiological acclimation and functional gene shifts of both plants and microbes. TheTECOmodel predicted that field warming from 2009 to 2013 resulted in cumulative C losses of 224 or 87\uffc2\uffa0g/m2, respectively, without or with changes in those parameters. Thus, warming\uffe2\uff80\uff90induced parameter changes reduced predicted soil C loss by 61%. Our study suggests that it is critical to incorporate biotic changes inESMs to improve the model performance in predicting C dynamics in permafrost regions.Despite their importance, how plant communities and soil microorganisms interact to determine the capacity of ecosystems to provide multiple functions simultaneously (multifunctionality) under climate change is poorly known. We conducted a common garden experiment using grassland species to evaluate how plant functional structure and soil microbial (bacteria and protists) diversity and abundance regulate soil multifunctionality responses to joint changes in plant species richness (one, three and six species) and simulated climate change (3\uffc2\uffb0C warming and 35% rainfall reduction). The effects of species richness and climate on soil multifunctionality were indirectly driven via changes in plant functional structure and their relationships with the abundance and diversity of soil bacteria and protists. More specifically, warming selected for the larger and most productive plant species, increasing the average size within communities and leading to reductions in functional plant diversity. These changes increased the total abundance of bacteria that, in turn, increased that of protists, ultimately promoting soil multifunctionality. Our work suggests that cascading effects between plant functional traits and the abundance of multitrophic soil organisms largely regulate the response of soil multifunctionality to simulated climate change, and ultimately provides novel experimental insights into the mechanisms underlying the effects of biodiversity and climate change on ecosystem functioning.Vast amounts of carbon are bound in both active layer and permafrost soils in the Arctic. As a consequence of climate warming, the depth of the active layer is increasing in size and permafrost soils are thawing. We hypothesize that pulses of biogenic volatile organic compounds are released from the near\uffe2\uff80\uff90surface active layer during spring, and during late summer season from thawing permafrost, while the subsequent biogeochemical processes occurring in thawed soils also lead to emissions. Biogenic volatile organic compounds are reactive gases that have both negative and positive climate forcing impacts when introduced to the Arctic atmosphere, and the knowledge of their emission magnitude and pattern is necessary to construct reliable climate models. However, it is unclear how different ecosystems and environmental factors such as drainage conditions upon permafrost thaw affect the emission and compound composition. Here we show that incubations of frozen B horizon of the active layer and permafrost soils collected from a High Arctic heath and fen release a range of biogenic volatile organic compounds upon thaw and during subsequent incubation experiments at temperatures of 10\uffc2\uffb0C and 20\uffc2\uffb0C. Meltwater drainage in the fen soils increased emission rates nine times, while having no effect in the drier heath soils. Emissions generally increased with temperature, and emission profiles for the fen soils were dominated by benzenoids and alkanes, while benzenoids, ketones, and alcohols dominated in heath soils. Our results emphasize that future changes affecting the drainage conditions of the Arctic tundra will have a large influence on volatile emissions from thawing permafrost soils \uffe2\uff80\uff93 particularly in wetland/fen areas.

There is empirical evidence that exceptionally dry or wet years have an impact on the net C balance in the Amazon. While seasonal and interannual variations in hydrology have a direct impact on the amounts of C transferred through the river\uffe2\uff80\uff93floodplain system, it is not known how far the variation of these fluxes affects the overall Amazon C balance. Here, we introduce a new wetland forcing file for the ORCHILEAK model, which improves the representation of floodplain dynamics and allows us to closely reproduce data\uffe2\uff80\uff90driven estimates of net C exports through the river\uffe2\uff80\uff93floodplain network. Based on this new wetland forcing and two climate forcing datasets, we show that across the Amazon, the percentage of net primary productivity lost to the river\uffe2\uff80\uff93floodplain system is highly variable at the interannual timescale, and wet years fuel aquatic CO2 evasion. However, at the same time overall net ecosystem productivity (NEP) and C sequestration are highest during wet years, partly due to reduced decomposition rates in water\uffe2\uff80\uff90logged floodplain soils. It is years with the lowest discharge and floodplain inundation, often associated with El Nino events, that have the lowest NEP and the highest total (terrestrial plus aquatic) CO2 emissions back to atmosphere. Furthermore, we find that aquatic C fluxes display greater variation than terrestrial C fluxes, and that this variation significantly dampens the interannual variability in NEP of the Amazon basin. These results call for a more integrative view of the C fluxes through the vegetation\uffe2\uff80\uff90soil\uffe2\uff80\uff90river\uffe2\uff80\uff90floodplain continuum, which directly places aquatic C fluxes into the overall C budget of the Amazon basin.Cover crops play an increasingly important role in improving soil quality, reducing agricultural inputs and improving environmental sustainability. The main objectives of this critical global review and systematic analysis were to assess cover crop practices in the context of their impacts on nitrogen leaching, net greenhouse gas balances (NGHGB) and crop productivity. Only studies that investigated the impacts of cover crops and measured one or a combination of nitrogen leaching, soil organic carbon (SOC), nitrous oxide (N2O), grain yield and nitrogen in grain of primary crop, and had a control treatment were included in the analysis. Long\uffe2\uff80\uff90term studies were uncommon, with most data coming from studies lasting 2\uffe2\uff80\uff933\uffc2\uffa0years. The literature search resulted in 106 studies carried out at 372 sites and covering different countries, climatic zones and management. Our analysis demonstrates that cover crops significantly (p\uffc2\uffa0<\uffc2\uffa00.001) decreased N leaching and significantly (p\uffc2\uffa0<\uffc2\uffa00.001) increased SOC sequestration without having significant (p\uffc2\uffa0>\uffc2\uffa00.05) effects on direct N2O emissions. Cover crops could mitigate the NGHGB by 2.06\uffc2\uffa0\uffc2\uffb1\uffc2\uffa02.10\uffc2\uffa0Mg CO2\uffe2\uff80\uff90eq\uffc2\uffa0ha\uffe2\uff88\uff921\uffc2\uffa0year\uffe2\uff88\uff921. One of the potential disadvantages of cover crops identified was the reduction in grain yield of the primary crop by \uffe2\uff89\uff884%, compared to the control treatment. This drawback could be avoided by selecting mixed cover crops with a range of legumes and non\uffe2\uff80\uff90legumes, which increased the yield by \uffe2\uff89\uff8813%. These advantages of cover crops justify their widespread adoption. However, management practices in relation to cover crops will need to be adapted to specific soil, management and regional climatic conditions.
