Ghimirey et al. (2025): Understanding soil carbon sequestration: mechanistic insights, management approaches, and future challenges

Vivek Ghimirey, Jay Chaurasia and Nobel Acharya, IN: Carbon Research, https://doi.org/10.1007/s44378-025-00133-5

Soil carbon sequestration (SCS) is a potent, nature-based solution to mitigate climate change by capturing atmospheric CO₂ and storing it in soils as organic matter or in mineral forms such as carbonates. This study examines data from 2000 to 2025, illustrating how SCS works, its benefits, and the challenges to scaling up at a global level. Organic carbon gets stabilized through processes like microbial action, humification, and plant decomposition, while inorganic carbon gets sequestered in soil minerals after undergoing chemical reactions. Effective methods to enhance SCS include sustainable agricultural practices, such as reduced tillage, cover crops, and agroforestry, as well as the use of biochar, organic compost, and wetland restoration.

Nature – Seabloom et al. (2025): Multidecadal persistence of soil carbon gains on retired cropland following fertilizer cessation

Eric W. Seabloom, Sarah E. Hobbie, Andrew S. MacDougall and Elizabeth T. Borer, IN: Nature Geoscience, https://doi.org/10.1038/s41561-025-01801-5

Humans have increased atmospheric carbon dioxide (CO₂), causing major changes in global climate while concurrently increasing the supply of biologically limiting nutrients especially nitrogen (N). Despite myriad negative effects on ecosystems and human health, nutrient pollution can increase the storage of soil carbon (C) in grasslands and retired farmland, potentially reducing atmospheric CO₂. However, the persistence of nutrient-induced soil carbon gains remains a knowledge gap at the heart of a potential policy dilemma: whether reducing nutrient pollution could lead to the release of soil carbon that accumulated under high nutrient supply. Here the authors use a four-decade experiment conducted on retired, marginal cropland to demonstrate that nutrient addition increased soil C storage after intensive tilling, and that these soil C gains persisted for at least three decades following fertilizer and tilling cessation.

de Moraes Sá et al. (2025): Net zero and net negative emissions in Brazilian biomes by no-till system

João Carlos de Moraes Sá, Rattan Lal, Klaus Lorenz, Yadunath Bajgai, Carla Gavilan, Ademir De Oliveira Ferreira, Clever Briedis, Thiago Massao Inagaki, Daniel Ruiz Potma Gonçalves and JeanKleber Bortoluzzi, IN: Science of The Total Environment, https://doi.org/10.1016/j.scitotenv.2025.180720

No-till systems (NTS) predicated on the tenets of conservation agriculture principles are a viable agricultural paradigm to achieve net zero or net negative emissions. The authors assessed the carbon dioxide equivalent (CO₂e) emissions based on soil organic carbon (SOC) stock changes in 1-m depth by plow-based tillage (PBT) and the mitigation potential through a no-till system (NTS) across 26 sites in the Cerrado biome and 37 sites in the Atlantic Forest biome.

Wang et al. (2025): Unlocking the potential of microbial necromass for enhancing soil carbon sequestration: A global perspective on cropland management using meta-analysis

Peng Wang, Ji Liu, Ying Liu, Lidong Mo, Junxi Hu, Zhiming Qi, Yong He and Qianjing Jiang, IN: Environmental Research, https://doi.org/10.1016/j.envres.2025.123008

The formation and sequestration of soil organic carbon (SOC) in croplands are significantly regulated by microbial necromass, a process strongly influenced by agricultural management. However, how management affects microbial necromass carbon (MNC) and its contributions to SOC stocks from an agroecological perspective remains insufficiently understood. To address this issue, the authors collected 834 paired aggregated experimental data from 77 studies worldwide, incorporated the influence of climate factors and soil physical and chemical properties, and constructed a necromass carbon database to reveal the impact of cropland management practices on microbial necromass and SOC.

Enebe et al. (2025): The impacts of biochar on carbon sequestration, soil processes, and microbial communities: a review

Matthew C. Enebe, Ram L. Ray and Richard W. Griffin, IN: Carbon Research, https://doi.org/10.1007/s42773-025-00499-3

Biochar application to the soil is an eco-friendly and sustainable nature-based solution for promoting soil carbon sequestration. It facilitates the reduction in the microbial carbon mineralization rate. Additionally, biochar enhances soil aggregate formation, neutralizes soil acidity, and increases microbial diversity, composition, and functions. The method adopted for this qualitative review entails a detailed examination of various research studies published on the contributions of biochar to soil carbon sequestration, its effect on the microbial community, and its contribution to greenhouse gas emission suppression, while also examining the various key factors that influence biochar’s functional potential as well as biochar’s contribution to environmental sustainability.

Holder et al. (2025): Genotypic Differences in Soil Carbon Stocks Under Miscanthus: Implications for Carbon Sequestration and Plant Breeding

Amanda J. Holder, Rebecca Wilson, Jeanette Whitaker, Paul Robson, IN: GCB Bioenergy, https://doi.org/10.1111/gcbb.70076

Biomass crops provide renewable material for bioproducts and energy generation with the potential for negative greenhouse gas emissions through bioenergy with carbon capture and storage. Miscanthus spp. is a perennial crop with rapid biomass production and low inputs. However, uncertainty exists over impacts on soil organic carbon (SOC) stocks in conversion from agricultural grasslands, and the interaction between divergent Miscanthus species and SOC sequestration. As a C4 plant (in contrast to C3 temperate grassland species) the fate of Miscanthus derived carbon can be traced in the soil through its isotopic signature. Taking advantage of this, the authors use soil cores (pre and post conversion) to investigate species groupings and genotypic effect on SOC stocks in a rare long-term field trial located in the UK.

Fulton et al. (2025): Tracing Blue Carbon Flows Across Diverse Seascapes

Christopher J. Fulton, Diego R. Barneche, Kay Davis, Cal Faubel, Cecilia Pascelli, Julie Vercelloni and Shaun K. Wilson, IN: Global Change Biology, https://doi.org/10.1111/gcb.70420

Plants occupying coastal ecosystems draw in carbon dioxide (CO₂) from the air and water around them during photosynthesis. A fraction of this CO₂ becomes fixed into plant biomass and can eventually contribute to the blue carbon pool—organic carbon (Corg) sequestered in slow-turnover sinks. An important step in protecting and enhancing this natural carbon sequestration pathway is determining the relative contributions of different coastal plants to this blue carbon pool in durable sinks. The authors compiled a global dataset of coastal soil carbon measurements and used a Bayesian hierarchical meta-regression model to explore the relative contribution of local (autochthonous) versus external (allochthonous) sources of Corg in the soils beneath tidal saltmarsh, mangrove, and seagrass wetlands.

El Zohbi et al. (2025): What regional agricultural actors want to know about carbon dioxide removal in Northern Germany

Juliane El Zohbi, Lea Griesing, Gabriele Torma, Diana Rechid, IN: Frontiers in Climate, https://doi.org/10.3389/fclim.2025.1627432

Many countries, including Germany, have made their climate targets dependent on the implementation of methods forto removing carbon dioxide from the atmosphere. Actors in the agricultural sector can contribute to this implementation. However, there is a knowledge gap regarding carbon dioxide removal (CDR) among agricultural actors. In this study, the authors interviewed 34 agricultural actors at the micro, meso, and macro levels to identify the factors hindering the implementation of CDR practices, namely soil carbon sequestration, biochar, and agroforestry. They identified 22 information needs related to the dimensions of Climate Change Mitigation, Technological Conditions, Environmental Impacts, Economics, Policy & Government, and Social Aspects from the interviews.
