Our study showed that stress-related crop response to changing environmental conditions can be detected by monitoring crops using satellite images at the landscape level. This could be useful for farmers to identify when stresses occur. Our results also suggest that satellite imagery can be used to discover soil impacts on crop development at farm fields. The inclusion of soil properties in satellite image analyses could further improve the accuracy of the prediction of drought stress on crops.

The role of soil aeration in carbon sequestration in arable soils has only been explored little, especially at the farm level. The current study, which was conducted on 30 fields that belong to individual farms, reveals a positive relationship between soil gas transport capability and soil organic carbon content. We therefore conclude that soil aeration needs to be accounted for when developing strategies for carbon sequestration in arable soil.

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.

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 the total global warming caused by 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 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.

This study evaluated the impact of diverse cover crops on topsoil mineral nitrogen (SMN), N2O emissions, and carbon (C) sequestration. Non-legume cover crops reduced SMN levels, showed potential for mitigating indirect N2O emissions, and increased C sequestration, but did not significantly reduce cumulative N2O emissions compared to fallow. The results highlight the need for tailored cover crop strategies to balance SMN capture, N2O emissions, and C sequestration effectively.

Agriculture may have a significant role on the climate change mitigation. For that reason, it is necessary to have good estimation of the greenhouse gases (GHG) emissions from the agricultural activities. In this work, two different chamber systems to determine GHG were compared. Our results highlighted that automated chamber systems, compared to manual chamber systems, are a powerful tool for quantifying GHG fluxes, allowing to capture the large temporal variability that characterizes them.

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.

Executive editor
This is an important forum article highlighting the lack of awareness into plant physiology in global soil carbon research. This issue is highly relevant as much of soil carbon cycling is driven by plant activity, in particular in the rhizosphere or related to plant symbionts. Their results are clear—the large majority of soil carbon studies do not include plant physiology even though a plant physiological perspective could provide novel or more mechanistic insights on soil carbon processes and could inform a new direction in soil carbon modelling.

Short summary
Plant physiology has been addressed by less than 10 % of peer-reviewed soil organic carbon research published in the last century. Thus, our understanding of soil carbon dynamics is overwhelmingly built on research that neglects the fundamental processes underlying organic carbon inputs. Active engagement of plant scientists in soil carbon research is imperative for shedding light on this blind spot and developing holistic policies that support soil carbon sequestration.
