Huang et al. (2026): Regulation of Water-Soluble Salt Ions by Plantations to Enhance Carbon Sequestration in Coastal Saline-Alkali Soils

Kaiwen Huang, Jiajun Ou, Wenyi Zhou, Rui Tan, Xin Liu, Ke Huang, Jinling Wang, Jie Lin, IN: Land Degradation & Development, https://doi.org/10.1002/ldr.70501

Soil carbon stability is critical for global carbon balance and ecosystem sustainability. Coastal saline-alkali lands have great potential for carbon sequestration, yet the mechanisms by which water-soluble salt ions regulate soil carbon dynamics remain unclear. To elucidate this relationship, this study systematically evaluated the co-variations among water-soluble salt ion distribution, soil chemical properties, and carbon fractions within the 0–100 cm soil profile under different plantation types (Taxodium hybrid “Zhongshanshan”, Carya cathayensis, and Ulmus parvifolia) in coastal saline-alkali land. The objective was to reveal the regulatory mechanisms of salt ions on soil carbon processes.

te Pas et al. (2026): Enhanced weathering and biochar co-deployment boosts CO₂ sequestration through changing soil properties

Emily E.E.M. te Pas, Rob N.J. Comans, Sarai Bisseling and Mathilde Hagens, IN: Geoderma, https://doi.org/10.1016/j.geoderma.2025.117668

Enhanced rock weathering (ERW) and biochar are potentially effective and scalable options for large-scale carbon dioxide removal (CDR), required to limit global temperature rise to 1.5 °C. Here the authors present experimental data on their co-deployment, an urgent and novel research direction that may render even larger CDR on multiple timescales.

Samanta et al. (2026): Sequestration of Carbon to Acquire Carbon Credit and Minimization of Potent Greenhouse Gases

Kousik Samanta, Madhurima Banik and Aminul Islam, IN: Environment and Ecology, https://doi.org/10.60151/envec/IOTI5134

The escalating global population, coupled with increased urbanization and industrialization, is placing immense strain on natural resources and exacerbating climate change through greenhouse gas (GHG) emissions. Primary sources of these emissions include the burning of fossil fuels, deforestation, and intensive agricultural practices, all of which release significant quantities of carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O). Soil organic carbon (SOC), representing the largest terrestrial carbon reservoir, is crucial in climate change mitigation as it sequesters atmospheric carbon. This study aims to assess the capacity of soil carbon sequestration and carbon credit mechanisms to reduce GHG emissions, enhance soil health, and foster sustainable agriculture.

Gholamahmadi & Kammann (2026): Biochar for durable carbon removal: soil erosion reduction as a key mechanism

Behrouz Gholamahmadi and Claudia Kammann, IN: Biochar, https://doi.org/10.1016/j.bmf.2026.100020

Soil erosion is a major pathway of physical soil organic carbon (SOC) loss and a critical threat to the permanence of land-based carbon dioxide removal (CDR). Biochar is widely recognised as a durable carbon sink, yet its hydrological effects and erosion-mitigation potential remain undervalued in CDR frameworks. Here the authors synthesise global evidence and long-term Mediterranean experiments to show that hydrological improvements—an enhanced soil sponge function—are not ancillary co-benefits but a core mechanism supporting carbon durability.

Perumalsamy et al. (2025): Materials-Based Approach for Enhanced Soil Carbon (C) Sequestration

Vibin Perumalsamy, Muhammad Ibrar Ahmed, Zhihao Lei, Ehsan Tavakkoli, Edward D. Burton, Nanthi Bolan, Ajayan Vinu and Jiabao Yi, IN: Small, https://doi.org/10.1002/smll.202510943

This review highlights recent advances in the use of nanostructured and natural nanoclay materials for soil carbon management. It outlines the importance of soil organic carbon (SOC), key challenges in SOC flux, the mechanisms of sequestration, and the societal implications of implementing these materials, providing groundwork for future research in this critical area.

Xu et al. (2025): Microbial-driven iron transformation and carbon stabilisation in flooded soils: roles of biochar and rock weathering

Qiao Xu, Gefeng Zhang, Feifan Zhang, Tharanga Bandara, Hongyan Guo, Meiling Xu and Caixian Tang, IN: Plant and Soil, https://doi.org/10.1007/s11104-025-08168-x

The escalating climate crisis demands innovative carbon dioxide removal strategies, with biochar and enhanced rock weathering (ERW) emerging as promising carbon-negative solutions. However, their contrasting effects on iron (Fe) (hydr)oxide–organic carbon (OC) interactions, a key mechanism underlying mineral-mediated C persistence, remain poorly understood.

A pot experiment examined the effects of biochar and enhanced basalt weathering alone and in combination on Fe oxide phases, C-binding capacity, Fe-complexed OC characteristics, and shifts in Fe-oxidising and reducing microbial communities via 16S rRNA sequencing in a paddy soil.

Jones et al. (2025): Evaluating the economic co-benefits of soil carbon sequestration: The test case of the UK

Philip Jones, Jacqueline Hannam and Chris Collins, IN: Land Use Policy, https://doi.org/10.1016/j.landusepol.2025.107839

There are no known valuations for ecosystem service flows from soil carbon for any country or region in the world. In this paper the authors make a first attempt to generate such data. The study aims were: develop a framework for acquiring international data for application to a specific region (UK); determine whether data limitations render it insufficient to inform the design of policies to encourage more C sequestration. Total ESS flows from existing soil carbon stock were estimated at £ 1140/ha, excluding food and feed.

Tian et al. (2025): Stover return enhances the transformation and sequestration of photosynthetic carbon through regulating soil food web

Yijia Tian, Xinchang Kou, Tingting An, Liangjie Sun, Qi Li, Wenju Liang, Xiaoke Zhang, IN: Journal of Cleaner Production, https://doi.org/10.1016/j.jclepro.2025.146910

In agroecosystems, the biological fixation of atmospheric carbon by crops through photosynthesis is one of the most important precursors of soil carbon sequestration. Residue return as a conservational agricultural management practice replenishes soil carbon substrates and triggers soil food web. However, there is still a lack of studies on the priming effect of residue return on photosynthetic carbon transformation and turnover, and then soil carbon sequestration through regulating soil food web, which hinders us from evaluating the efficiency and sustainability of resource utilization. To analyze the priming effect of residue return, stover return (SR) and stover removal (CK) were conducted in the maize field experiment. Then the situ ¹³C labeling microplot experiment was further carried out to trace crop photosynthetic carbon turnover pathway into soil on the basis of the field experiment.

Syaranamual et al. (2025): Influence of biochar, compost, and their combination on carbon mineralisation and the priming effect in low-carbon soil: an incubation experiment

Siska Syaranamual, Bahareh Bicharanloo, Shamim Mia & Feike A. Dijkstra, IN: Carbon Research, https://doi.org/10.1007/s44378-025-00139-z

Integrating biochar and compost into soils can enhance both carbon (C) sequestration and soil fertility. However, their combined effects on C mineralisation and priming in C-poor soils are not well understood. To address this gap, the authors conducted a 120-day laboratory incubation study. They applied biochar (2%) and compost (2%) individually and in combination (1% each) to a soil with low organic C content (0.12%).
