Short summary
Wetlands are one of the most significant natural sources of the strong greenhouse gas methane. We developed a model that can be used within a larger wetland carbon model to simulate the methane emissions. In this study, we present the model and results of its testing. We found that the model works well with different settings and that the results depend primarily on the rate of input anoxic soil respiration and also on factors that affect the simulated oxygen concentrations in the wetland soil.

Soil produces 98.8 % of the calories consumed by humans, but the contribution that the anthropogenic use of soil makes to global warming is not clear. We show that soil has contributed 15 % of entire global warming caused by the well-mixed greenhouse gases. Thus, our finding that soil is a substantial contributor to global anthropogenic greenhouse gas emissions represents a ‘wicked problem’ – how do we continue to increase food production from soil whilst also decreasing emissions?

We conducted a service soil laboratory comparison study and tested the individual effect of common sieving, grinding, drying and quantification methods on total, inorganic, and organic soil carbon (C) measurements. We found that inter-lab variability is large and each soil processing step impacts C measurement accuracy and/or precision. Standardizing soil processing methods is needed to ensure C measurements are accurate and precise, especially for C credit allocation and model calibration.

This work addresses air–ground temperature coupling and propagation into the subsurface in a mountainous area in central Spain using surface and subsurface data from six meteorological stations. Heat transfer of temperature changes at the ground surface occurs mainly by conduction controlled by thermal diffusivity of the subsurface, which varies with depth and time. A new methodology shows that near-surface diffusivity and soil moisture content changes with time are closely related.

The aim of this study was to investigate the effects of different biopreparations on soil porosity, temperature, and CO2 emission from the soil in northeast Europe (Lithuania) when growing food-type crops. The application of the biopreparations showed a cumulative effect on the soil properties. In the third year of the study, the total porosity of the soil was higher in all scenarios compared to the control, ranging between 51% and 74%.

Earthworm invasion in North American forests can alter soil functioning. We investigated how the presence of invasive earthworms affected microbial communities, key drivers of soil biogeochemistry, across the major soil types of the Canadian boreal forest, which is a region largely understudied. Although total microbial biomass did not change, community composition shifted in earthworm-invaded mineral soils, where we also found higher fungal biomass and greater microbial species diversity.

We analyzed intensification of Uruguayan grasslands in a country-wide survey on fertility proxies, pH and trace metals in topsoils. We observed a loss of nutrients, trace metals and organic matter in grasslands, croplands and timber plantations and accumulation in riverine forests. This raises questions about the carrying capacity of Uruguayan soils with regard to currently implemented intensification strategies and supports more conservative forms of extensive grassland management.

Major soil carbon pools and fluxes were assessed along a climatic gradient expanding 4 °C in mean annual temperature for two important boreal conifer forest stand types. Species and a warmer climate affected soil organic matter (SOM) cycling but not stocks. Contrarily to common hypotheses, SOM lability was not reduced by warmer climatic conditions and perhaps increased. Results apply to cold and wet conditions and a stable vegetation composition along the climate gradient.

We explored the effects of mild alternate wetting and drying (AWD) irrigation combined with rice straw return on N2O emissions and rice yield through rice pot experiments. Mild AWD irrigation significantly increased both N2O and yield-scaled N2O emissions. The addition of rice straw under mild AWD irrigation could promote N2O emissions. Mild AWD irrigation could reduce soil-nitrogen uptake by rice when urea was applied. Mild AWD irrigation reduced rice aboveground biomass but not rice yield.

How subsoil microorganisms respond to warming is largely unknown, despite their crucial role in the soil organic carbon cycle. We observed that the subsoil microbial community composition was more responsive to warming compared to the topsoil community composition. Decreased microbial abundance in subsoils, as observed in this study, might reduce the magnitude of the respiration response over time, and a shift in the microbial community will likely affect the cycling of soil organic carbon.

We do not understand the short- and long-term temperature response of soil denitrifiers, which produce and consume N2O. Boreal forest soils from a long-term climate gradient were incubated in short-term warming experiments. We found stronger N2O consumption at depth, inconsistent microbial gene abundance and function, and consistent higher N2O emissions from warmer-climate soils at warmer temperatures. Consideration of our results in models will contribute to improved climate projections.

Research was conducted to assess the response of microbial communities in a soil with a long history of glyphosate-based herbicides to a secondary imposed perturbation (dry–rewetting event). Both perturbations could increase their frequency under current agricultural practices and climate change. The results of this study demonstrate that acute exposure to a glyphosate-based herbicide does not have a conditioning effect on the response of microbial communities to the dry–rewetting event.

Global warming leads to increased mineralisation of soil organic matter, inducing a positive climate–carbon cycle feedback loop. Loss of organic matter can be associated with loss of soil structure. Here we use a strong geothermal gradient to investigate soil warming effects on soil organic matter and structural parameters in subarctic forest and grassland soils. Strong depletion of organic matter caused a collapse of aggregates, highlighting the potential impact of warming on soil function.

The sub-humid Argentine Chaco, originally covered by forest, has been subjected to clearing since the end of the 1970s and replacement of the forest by no-till farming. The organic carbon stock content up to 1 m depth varied as follows: forest > pasture > continuous cropping, with no impact of the number of years under cropping. The incorporation of pastures of warm-season grasses was able to mitigate the decrease of C stocks caused by cropping and so could be considered sustainable management.

In this study we evaluated CO2 emissions during composting of green wastes with clay and/or biochar in the presence and absence of worms, as well as the effect of those amendments on carbon mineralization after application to soil. Our results indicated that the addition of clay or clay–biochar mixture reduced carbon mineralization during co-composting without worms by up to 44 %. In the presence of worms, CO2 emissions during composting increased for all treatments except for the low clay dose.

Using ranges for variables in a model of organic C stocks of the top 1m of soil on a global 0.5° grid, we assessed the (un)certainty of changes in stocks over the next 75 years. Changes are more certain where land-use change strongly affects carbon inputs and where higher temperatures and adequate moisture favour decomposition, e.g. tropical mountain forests. Global stocks will increase by 1% with a certainty of 75% if inputs to the soil increase due to CO₂ fertilization of the vegetation.

Short summary
We studied greenhouse (GHG) gas fluxes at an agricultural peat soil site with willow, forage and set-aside. The mean annual water table rose from 80 to 30 cm in 2019–2022. Raising the water table slowed down annual CO2 emissions. CH4 fluxes changed from uptake to emissions, and nitrous oxide emissions decreased towards the end of the experiment. The total greenhouse gas balance was relatively high, highlighting the challenge in mitigating emissions from cultivated peatlands.
