Short summary
This study follows organic carbon from soils along sediment flow paths at catchment scale to analyse the evolution of OC pools. Selectivity of particles during detachment and transport, and protection of OC during transport and deposition are key for the concentration and quality of OC at depositional settings and for the terrestrial carbon sink. OC can also be increased by ecological processes and by replacement in eroded areas, converting catchments into relevant sinks for C budget.

In order to ensure climate change mitigation via carbon sequestration by temperate grasslands, we suggested modifications to soil organic carbon model to be more adapted to grassland-based livestock systems under humid temperate conditions. The modifications do not impair the performance of the model under temperate conditions and so represent a broadening in its capability. It could be a useful tool for policy makers to develop effective strategies to reduce climate change effect.

Short summary
Extreme weather, like heavy rainstorms and droughts, will become more frequent under climate change, jeopardizing water availability. We show that climate change in a large Mediterranean catchment leads to a redistribution of water from soil to reservoirs and to increased crop stress. Furthermore, increased soil erosion threatens the storage capacity of reservoirs. We conclude that climate change may affect rainfed and irrigated agriculture potential and threatens overall water security.

Short summary
Climate change will likely increase soil erosion in many locations worldwide. This increase in erosion will have large-scale impacts, such as the siltation of reservoirs. We developed a new soil erosion model to evaluate these impacts, which has an advantage over existing models in that it includes most relevant processes: rainfall–runoff generation, vegetation development, and soil erosion and deposition. The model is suited to perform scenario studies on climate change and land management.

The mobility of pyrogenic organic matter (PyOM) in soils is largely unknow, while it is a major and persistent component of the soil organic matter. With a soil column experiment, we identified that only a small proportion of PyOM can migrate through the soil, but its export is continuous. Aging and associated oxidation increase its mobility but also its retention in soils. Further, PyOM can alter the vertical mobility of native soil organic carbon during its downward migration.

The release of CO2 from soils, known as soil respiration, plays a major role in the global carbon cycle. However, the contributions of different soil depths or the sources of soil CO2 have hardly been studied. We quantified the CO2 production for different soil layers (up to 1.5 m) in three soil profiles for 2 years. We found that 90 % of CO2 production occurs in the first 30 cm of the soil profile, and that the CO2 originated from young carbon sources, as revealed by radiocarbon measurements.

The novelty of our work is that it presents a series of potential interactions between drivers of soil organic carbon at broad scales in temperate mountain grasslands. The most relevant contribution of our work is that it illustrates the importance of grazing management for soil carbon stocks, indicating that interactions between grazing species and soil nitrogen and herbage quality may be promising paths in order to design further management policies for palliating climate change.

Soil phosphorus (P) management is a critical challenge for agriculture worldwide; yet, simulation models of soil P processes lag those of other essential nutrients. In this review, we identify hindrances to measuring and modeling soil P pools and fluxes. We highlight the need to clarify biological and mineral interactions by defining P pools explicitly and using evolving techniques, such as tracing P in phosphates using oxygen isotopes.

Short summary
The intensive management of large-scale oil palm plantations may result in high nutrient leaching losses which reduce soil fertility and potentially pollute water bodies. The reduction in management intensity with lower fertilization rates and with mechanical weeding instead of the use of herbicide results in lower nutrient leaching losses while maintaining high yield. Lower leaching results from lower nutrient inputs from fertilizer and from higher retention by enhanced cover vegetation.

The 4 per 1000 initiative aims to restore carbon storage in soils to both mitigate climate change and contribute to food security. The French National Institute for Agricultural Research conducted a study to determine the carbon storage potential in French soils and associated costs. This paper is a part of that study. It reviews recent advances concerning the mechanisms that controls C stabilization in soils. Synthetic figures integrating new concepts should be of pedagogical interest.

Inositol phosphates (IPs) are a major pool of organic P in soil. However, information on their diversity and abundance in soil is limited. We isolated IPs from soil and characterised them using solution nuclear magnetic resonance (NMR) spectroscopy. For the first time, we provide direct spectroscopic evidence for the existence of a multitude of lower-order IPs in soil extracts previously not detected with NMR. Our findings will help provide new insight into the cycling of IPs in ecosystems.

We present a simple model that describes, for the first time, the dynamic two-way interactions between soil organic matter and soil physical properties (porosity, pore size distribution, bulk density and layer thickness). The model was able to accurately reproduce the changes in soil organic carbon, soil bulk density and surface elevation observed during 63 years in a field trial, as well as soil water retention curves measured at the end of the experimental period.

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.

Understanding controls on the persistence of organic matter in soils is essential to constrain its role in the carbon cycle. Emerging concepts suggest that the soil carbon pool is predominantly comprised of stabilized microbial residues. To test this hypothesis we isolated microbial membrane lipids from two Swiss soil profiles and measured their radiocarbon age. We find that the ages of these compounds are in the range of millenia and thus provide evidence for stabilized microbial mass in soils.

Soil organic carbon sequestration across agroecosystems worldwide can contribute to mitigate the effects of climate change by reducing levels of atmospheric carbon dioxide. Maximum carbon sequestration potential is frequently estimated using the linear regression equation developed by Hassink (1997). This work examines the suitability of this equation for use in grasslands across the United Kingdom. The results highlight the need to ensure the fit of equations to the soils being studied.

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.

Humid tropical soils are important sources and sinks of methane. We used model simulation to understand how different kinds of microbes and observed soil moisture and oxygen dynamics contribute to production and consumption of methane along a wet tropical hillslope during normal and drought conditions. Drought alters the diffusion of oxygen and microbial substrates into and out of soil
microsites, resulting in enhanced methane release from the entire hillslope during drought recovery.

This study presents a well-defined and comprehensive experimental setup analyzing total denitrification, i.e. N2O and (N2O+N2) fluxes, in combination with X-ray CT image analysis. (N2O+N2) fluxes were mainly controlled by the interplay of oxygen supply and demand. The former could be estimated by abiotic proxies like the extent of anaerobic soil volumes or diffusivity, whereas the latter was best described by CO2 production or SOM. N2O fluxes additionally depended on the N2O reduction.

Large amounts of organic carbon (OC) in soil are protected against decay by bonding to minerals. We studied the release of mineral-bonded OC by NaF-NaOH extraction and H2O2 oxidation. Unexpectedly, extraction and oxidation removed mineral-bonded OC at roughly constant portions and of similar age distributions, irrespective of mineral composition, land use, and soil depth. The results suggest uniform modes of interactions between OC and minerals across soils in quasi-steady state with inputs.

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.

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.

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.

Ultrasonication/density fractionation is a common method used to extract particulate organic matter (POM) and, recently, microplastic (MP) from soil samples. In this study, ultrasonic treatment with mechanical stress increasing from 0 to 500 J ml−1 caused comminution and a reduced recovery rate of soil derived POMs, but no such effects with MP particles. In consequence, the extraction of MP from soils is not affected by particle size and recovery rate artifacts.

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.

To quantify Phosphorus loss from forests by vertical and lateral soil water flow, we conducted six sprinkling experiments at three beech forests in Germany. Out data showed a nutrient flashing (high P concentrations) during the first 2 hours after the onset but no further depletion thereafter. This suggest that the mobilization of P can keep up with its transport. We also showed that the P concentrations decreased with soil depth suggesting an efficient retention of P in the forest soil.

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. Results revealed salinity-driven gradients in molecular-level C chemistry, with little evidence of an association between C chemistry and microbial community assembly processes.

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.

Short summary
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.
Understanding the mechanisms of OC stabilization within Mediterranean river systems could have...
