Short summary
This study set out to determine the quantity of organic carbon (OC) which is protected from microbial decomposition in macro-aggregates of Siberian steppe soils under different land use. Our results imply that the quantity of macro-aggregate protected OC is smaller than in similar steppe ecosystems like the North American prairies. We conclude that the tillage-induced breakdown of macro-aggregates after grassland to arable land conversion has not reduced the OC contents in the studied soils.

We studied the contribution of litter-derived carbon (C) in the formation of subsoil organic matter (OM). Soil core sampling, 13C field labeling, density fractionation, and water extractions were used to track its contribution to different functional OM fractions down to the deep subsoil. We show that while migrating down the soil profile, OM undergoes a sequence of repeated sorption, microbial processing, and desorption. However, the contribution of litter-derived C to subsoil OM is small.

The main contribution of our study is our finding that rhizodeposits and microbe-assimilated carbon contribute significantly to the sequestration of carbon substrates in rice paddy soils. This contribution is theoretically and practically relevant because few studies have investigated the effects of different carbon substrates on the mineralization of native soil organic carbon and our findings have immediate applications for improving the fertility of paddy soils and mitigating global warming.

We studied the spatial distribution of soil C, N, and P (carbon, nitrogen, and phosphorus) stoichiometry of the ecosystems in a subtropical catchment, and found that the stoichiometry was shaped in relatively narrow ranges in agricultural uses, and its spatial variations with topography were remarkably reduced. Thus, our findings demonstrate that intensive agriculture can change the spatial distributions of soil C, N, and P and the associated stoichiometry in a hilly subtropical catchment.

In this study, we provide a holistic view of soil responses to precipitation changes. A total of 16 meta-analyses focusing on the effects of precipitation changes on 42 soil response variables were compared. A strong agreement was found that the belowground carbon and nitrogen cycling accelerate under increased precipitation and slow under decreased precipitation, while bacterial and fungal communities are relatively resistant to decreased precipitation. Knowledge gaps were also identified.

Short summary
Large amounts of soil organic matter stored in permafrost-affected soils from Arctic Russia are present as undecomposed plant residues. This large fibrous organic matter might be highly vulnerable to microbial decay, while small mineral-associated organic matter can most probably attenuate carbon mineralization in a warmer future. Labile soil fractions also store large amounts of nitrogen, which might be lost during permafrost collapse while fostering the decomposition of soil organic matter.

To better understand the mercury (Hg) content in northern soils, we measured Hg concentration in peat cores across a 1700 km permafrost gradient in Siberia. We demonstrated a northward increase in Hg concentration in peat and Hg pools in frozen peatlands. We revised the 0–30 cm northern soil Hg pool to be 72 Gg, which is 7 % of the global soil Hg pool of 1086 Gg. The results are important for understanding Hg exchange between soil, water, and the atmosphere under climate change in the Arctic.

The apparent respiration quotient (ARQ) changes according to which substrates microbes consume, allowing sources of soil respiration to be traced. In a forest soil warming experiment, ARQ had a strong seasonal pattern that reflected a shift from respiration being fueled by sugars and organic acids derived from roots during the growing season to respiration being fueled by dead microbes during winter. ARQ values also changed with experimental warming.

Four wheat cultivars were labeled with 13CO2 to quantify the effect of rooting depth and root biomass on the belowground transfer of organic carbon. We found no clear relation between the time since cultivar development and the amount of carbon inputs to the soil. Therefore, the hypothesis that wheat cultivars with a larger root biomass and deeper roots promote carbon stabilization was rejected. The amount of root biomass that will be stabilized in the soil on the long term is, however, unknown.

Short summary
Experimental warming increased soil respiration (Rs) by more than 25 % in a Tasmanian C-rich soil, but there was no impact on microbial respiration in laboratory experiments. Plant community composition had no effect on Rs, suggesting the response is likely due to enhanced belowground plant respiration and C supply through rhizodeposition and root exudates. Results imply we need studies of both C inputs and losses to model net ecosystem C exchange of these crucial, C-dense systems effectively.

Blue carbonecosystems – tidal marsh, mangrove, and seagrass – serve as important organic carbon sinks, mitigating impacts of climate change. We utilized a robust regional carbon stock dataset to identify ecological, geomorphological, and anthropogenic drivers of carbon stock variability and create high-spatial-resolution predictive carbon stock maps. This work facilitates strategic conservation and restoration of coastal blue carbon ecosystems to contribute to climate change mitigation.

The microbial C : N ratio increased with aridity, while the microbial N : P ratio decreased with aridity, which implied that drought-stimulated microbes tend to be more N conservative. Among all examined ecological factors, substrate supply and microbial structure together controlled the microbial stoichiometry. Overall, these results illustrated N and P limitation in microbial biomass at deeper soil depths along the aridity gradient and limited responses to ecological factors in the subsoil.

We studied how species number and abundance of the understorey vegetation correlates with nutrient contents of soil and tree leaves at a northern boreal forest site. The phosphorus (P) content of the humus layer showed higher correlation with vegetation than the nitrogen (N) content. Usually N is considered more important in boreal forests. The plots with high P content in humus had birch as the dominant tree species, implying that birch leaf litter is an important source of P to the plants.

Temperate rainforests of the Pacific Northwest often have productive soils with high levels of organic matter. We describe the nitrogen and phosphorus attributes of this soil organic matter in relation to the growth of four conifer species. Sitka spruce thrived on high-nitrogen soils, more so than the other conifer species, but productivity overall is likely constrained by phosphorus deficiencies. Study results will guide wood production, carbon sequestration and conservation priorities.

Soil is the largest carbon pool in forests. Whether forest soils function as a sink or source of atmospheric carbon remains controversial. Here, we investigated the 20-year changes in the soil organic carbon pool at eight permanent forest plots in China. Our results revealed that the soils sequestered 3.6–16.3 % of the annual net primary production across the investigated sites, demonstrating that these forest soils have functioned as an important C sink during the past 2 decades.

Reliable methods are required for estimating mineral supply rates to forest growth from weathering. We applied the depletion method, the PROFILE model and the base cation budget method to two forest sites in Sweden. The highest weathering rate was obtained from the budget method and the lowest from the depletion method. The high rate by the budget method suggests that there were additional sources for tree uptake not captured by measurements.

Phosphorus (P) is an important soil nutrient that often limits plant growth and microbial activity in humid tropical forests. These ecosystems receive a large amount of rainfall that helps create frequent anoxic events in soils. Our results show that anoxic conditions reduced the strength of soil minerals to bind P even though a large amount of P was still bound to minerals. Our study suggests that anoxic events might serve as hot moments for plants and microbes to acquire P.

Agropedogenesis, i.e. soil development under agricultural use, is the anthropogenic modification of soil and environmental factors for optimization of crop production. Maximization of only this function, crop production, leads to declines in all other soil functions and consequently promotes uniformity in soil properties around the globe. Here we developed a new scientific background for the theory of agropedogenesis and the identification of soil degradation stages.

The release of elements from soil through weathering is an important process, controlling nutrient availability for plants and recovery from acidification. However, direct measurements cannot be done, and present estimates are burdened with high uncertainties. In this paper we use different approaches to quantify weathering rates in different scales in Sweden and discuss the pros and cons. The study contributes to more robust assessments of sustainable harvesting of forest biomass.

The N–transformation rates and N–related functional gene abundance were surveyed in a tropical forest soil with experimental N additions. The C : N ratio was the determinant factor for N transformations in the dry season while the microbial biomass was the one in the wet season. This study also found that high N addition imposed significant positive effects on the functional gene abundance of AOA amoA and nirK but negative effects on that of AOB amoA and nosZ.

Forest soils have a steep carbon gradient from the forest floor to the mineral soil, indicating that carbon is prevented from entry into the soil. Wild boar are effective in mixing the soil when searching for food. In a 6–year field study, we found no significant changes in soil organic carbon stocks in the wild boar treatment plots. However, around 50 % of forest floor carbon was transferred with mixing into mineral soil carbon and increased the stabilised fraction of soil organic carbon.

Decaying animals perturb soil biogeochemical cycles. Stable δ15N composition, which reflects the sum of all biogeochemical processes, increases during decay and persists for years. Enrichment following beaver decay persisted after at least 1 year, and was evident up to 10 cm depth and 60 cm from the decaying animals, beyond where soils were visibly impacted by decomposition. Nutrients sourced from decaying animals represent an integral and long–lived component of nitrogen cycling in soils.

Coastal terrestrial–aquatic interfaces represent dynamic yet poorly understood zones of biogeochemical cycles. We evaluated associations between the soil salinity gradient, molecular-level soil-C chemistry, and microbial community assembly processes in a coastal watershed on the Olympic Peninsula in Washington, USA.

A combination of gas chromatography and X-ray CT reveals the microscale processes that govern soil respiration. Aerobic and anaerobic respiration in microbial hotspots depends not only on the quality and quantity of soil organic matter, but also on the spatial distribution of hotspots. Denitrification kinetics are mainly governed by hotspot architecture due to local competition for oxygen during growth. Cumulative behavior is mainly governed by water saturation due to the overall supply with O2.

We examined the effects of elevated CO2, pine seedlings, and ectomycorrhizal fungi on mineral weathering. Seedlings significantly increased mineral weathering, while elevated CO2 increased plant growth and organic acid concentrations but had no effect on weathering. Ectomycorrhial fungi showed some tendency to increase weathering. We conclude that nutrient uptake, which reduces transport limitation to weathering, is the primary mechanism by which plants enhanced weathering in this system.

Using pathway analysis, we demonstrate that past aridity's effect is mediated by differential mechanisms for substrates of varied complexity. While microbial biomass plays a more important role in the decomposition of fresh litter, enzyme-catalyzed extracellular reactions predominantly govern the mineralization of SOC. Our findings have significant implications for assessing and modeling decomposition in different aridity regimes.

Plant functional traits have increasingly been studied as determinants of ecosystem properties. While the relationships between biological community structures and ecological functions remain poorly understood at the large scale, we found that there was considerable variation in the profiles of different substrate uses along the NSTEC. The soil silt content and plant functional traits together shaped the biogeographical pattern of the soil microbial substrate use.

The carbon stored in soils is the largest reservoir of organic carbon on land. In the context of greenhouse gas emissions and a changing climate, it is very important to understand how stable the carbon in the soil is and why. The deeper parts of the soil have often been overlooked even though they store a lot of carbon. In this paper, we discovered that although deep soil carbon is expected to be old and stable, there can be a significant young component that cycles much faster.

Efforts to understand the global phosphorus (P) cycle are limited by the scarcity of global data on rates of soil P processes, as well as on its environmental controls. Here, we present a novel approach using radiophosphorus labeling of soils, which allows for the measurement of fluxes of abiotic and biotic soil P processes. This approach is also suitable for strongly weathered and P-depleted soils. Biotic processes are corrected for abiotic processes by comparing live and sterile soils.

Surface soils interact strongly with both climate and biota and provide fundamental ecosystem services. However, the quantitative linkages between soil, climate, and biota remain unclear at a global scale. By compiling a large global soil database, we mapped eight major soil properties based on machine learning algorithms and developed a global soil–climate–biome diagram. Our results suggest shifts in soil properties under global climate and land cover change.

Organic carbon (C) stocks within seasonal wetlands are vulnerable to increased severity and duration of droughts in response to climate change. Here we examined the mechanistic controls on C cycling in seasonally flooded mineral wetland soils. We found that different mechanisms preserve C in surface layers (oxygen limitations) compared to subsurface layers (mineral protection and lack of root C inputs).

James Ross Island offers the opportunity to study the undisturbed interplay of microbial activity and pedogenesis. Soils from two sites representing coastal and inland conditions were chosen and analyzed with a wide range of techniques to describe soil properties. We are able to show that coastal conditions go along with more intense weathering and therefore favor soil formation and that microbial communities are initially more affected by weathering and structure than by chemical parameters.

We estimate heterotrophic respiration (Rh) – the respiration from microbes in the soil – using satellite estimates of the net carbon flux and other quantities. Rh is an important carbon flux but is rarely studied by itself. Our method is the first to estimate how Rh varies in both space and time. The resulting new estimate of Rh is compared to the best currently available alternative, which is based on interpolating field measurements globally. The two estimates disagree and are both uncertain.

Denitrification is a key process in the soil nitrogen cycle but poorly investigated due to methodical limitations. The 15N gas flux method is currently the only approach allowing field measurement of denitrification but was subject to bias due to unaccounted fluxes of 15N-labelled gaseous denitrification products to the subsoil. We used field flux experiments and diffusion–reaction modelling to estimate this source of error and developed an approach to correct denitrification rates.

Rare earth mining processes require the removal of topsoil that is mechanically scraped off and relocated to topsoil stockpiles, which proved beneficial for microbial biobanking. But there appears to be a critical time frame for holding topsoil, and rainfall penetration into the stockpile may result in the demise of cyanobacteria. In the longer term, provided conditions are favourable, there may be adequate cyanobacterial survival, at least down to 50 cm, to recolonise the soil surfaces.

In a context of global changes, modeling and predicting the dynamics of soil carbon stocks in forest ecosystems are vital but challenging. Yasso07 is considered to be one of the most promising models for such a purpose. We examine the accuracy of its prediction of soil carbon dynamics over the whole French metropolitan territory at a decennial timescale. We revealed how the bottleneck in soil carbon modeling is linked with the lack of knowledge on soil carbon quality and fine-root litter.

Mineral binding is a major mechanism for soil carbon (C) stabilization. However, soil minerals can also inhibit the growth of bacteria that protect organic C from decay. Here the findings indicate that reduced surface Fe(II) derived from Fe(III)-containing minerals inhibits the growth of bacteria via a free-radical mechanism, which may serve as an ubiquitous mechanism between iron minerals and all of the heterotrophic bacteria in view of bacteria as a vast source of superoxide.

Soils store large amounts of carbon in soil organic matter, which comes from plant debris and roots. The mechanisms protecting it from biodegradation are not fully understood. Here, we carry out a size-fractionation of soil sampled on different dates in a field experiment. Using carbon and nitrogen content and spectroscopy and microscopy we conclude that organic matter enriched in nitrogen is preferentially protected from biodegradation and that clay minerals have differing protective abilities.

Soil water is a medium from which microbes acquire resources and within which they are able to move. Occupancy and availability of water and oxygen gas in soils are mutually exclusive. In addition, as soil dries the remaining water is held with an increasing degree of adhesive energy, which restricts microbes' ability to extract resources from water. We introduce a mathematical model that describes these interacting effects and organic matter decomposition.

Understanding the mechanisms of OC stabilization within Mediterranean river systems could have important implications for the stability of soil carbon stocks affected by erosion. These results underline the importance of studying soil erosion, soil formation, and geomorphological processes together in semiarid and subhumid catchments, where intermittent fluvial courses are predominant. Good management of these environments will be a powerful tool for climate change mitigation.

Carbon stored in coastal wetlands is of global relevance to climate regulation, but broadscale inventories of this "blue carbon" are lacking. Sampling salt marshes in the UK, we developed a predictive tool with the capacity to predict up to 44 % of spatial variation in soil carbon from simple observations of plant community and soil type. Marsh-specific maps of soil carbon were also produced, demonstrating the application of this easy-to-use tool for landscape-scale predictions of blue carbon.

Increasing shrub cover promotes land degradation in semi-arid grasslands and has the potential to impact the soil nitrogen pool, which is essential to primary production. Our study showed that increasing shrub cover concentrates soil nitrogen into localised patches beneath shrub canopies. Further, we determined that increasing shrub cover inhibits inputs of nitrogen by the soil microbial community. Thus, we conclude this phenomenon can perturb nitrogen cycling in these ecosystems.

Our laboratory study shows how microhabitat formation linked to soil aggregates, litter accumulation and plant soil interactions affects conditions under which
hot momentsof enhanced N2O emissions from floodplain soils during the drying phase after saturation occur. Larger aggregate size led to higher integrated flux rates when soil was unamended or mixed with leaf litter, whereas planting with willow significantly reduced emissions. Also, emission time patterns differed among the treatments.

Arctic soils store vast amounts of frozen carbon that will thaw, fueling microbes that produce carbon dioxide and methane greenhouse gases. We compared methane producing and oxidizing activities in incubated soils and permafrost of Arctic tundra to improve estimates of net emissions. The methane oxidation profile in these soils differs from temperate ecosystems: maximum methane oxidation potential occurs in suboxic soils and permafrost layers, close to the methanogens that produce methane.

Arctic warming mobilizes belowground organic matter in northern high latitudes. This study focused on the size of organic carbon pools and organic matter quality in ice-rich permafrost on the Baldwin Peninsula, West Alaska. We analyzed biogeochemistry and found that three-quarters of the carbon is stored in degraded permafrost deposits. Nonetheless, using biomarker analyses, we showed that the organic matter in undisturbed yedoma permafrost has a higher potential for decomposition.

Eucalyptus plantations produce large extensions of fine roots that release energy-rich organic compounds into the soil, causing an increase in the number of microorganisms that degrade soil organic matter and release N to the trees, in the so-called rhizosphere priming effect. In order to estimate the quantitative importance of this phenomena, a mechanistic model was elaborated – the ForPRAN. It has been estimated that rhizosphere cycling can supply about 24.6 % of N accumulated in Eucalyptus.

Biocrusts are photosynthetic communities on the surface of many desert soils. We investigated the response of biocrusts and the soil beneath them (including plant roots) to 9 years of simulated warming and changing precipitation patterns. We monitored the exchange of carbon between soil and atmosphere using automated chambers. As plants and biocrusts responded negatively to the treatments, we saw reduced photosynthesis in biocrusts but variable overall carbon exchange over 9 years.

Short summary
This study suggests that soil moisture significantly affects soil organic matter dynamics along a salinity gradient in semiarid steppe soils. The covarying moisture gradient along the salinity gradient serves as an explanatory factor for (i) the increasing soil organic carbon (OC) stocks with increasing salinity, (ii) the constant proportion and stability of particulate OC along the transect, and (iii) a similar fungi : bacteria ratio in the topsoils along the studied gradient.
This study suggests that soil moisture significantly affects soil organic matter dynamics along...
