Aragon et al. (2024): The Realistic Potential of Soil Carbon Sequestration in U.S. Croplands for Climate Mitigation

Nazli Uludere Aragon, Yanhua Xie, Daniel Bigelow, Tyler J. Lark, Alison J. Eagle IN: Earth’s Future, 12, https://doi.org/10.1029/2023EF003866

Existing estimates of the climate mitigation potential from cropland carbon sequestration (C-sequestration) are limited because they tend to assume constant rates of soil organic carbon change over all available cropland area, use relatively coarse land delineations, and often fail to adequately consider the agronomic and socioeconomic dimensions of agricultural land use. This results in an inflated estimate of the C-sequestration potential. The authors address this gap by defining a more appropriate land base for cover cropping in the United States for C-sequestration purposes: stable croplands in annual production systems that can integrate cover cropping without irrigation.

Ilakiya et al. (2024): Unlocking the Carbon Sequestration Potential of Horticultural Crops

Tamilselvan Ilakiya, Ettiyagounder Parameswari, Ramakrishnan Swarnapriya, Gunasekaran Yazhini, Periasamy Kalaiselvi, Veeraswamy Davamani, Sudha Singh, Nedunchezhiyan Vinothini, Chelladurai Dharani, Sneha Leela Garnepudi, Ramasamy Ajaykumar IN: Journal of Carbon Research, 10, https://doi.org/10.3390/c10030065

Horticultural crops offer a unique chance to sequester a considerable amount of atmospheric carbon dioxide. In order to fully use this capacity, it is essential to employ effective carbon management systems. Although there are advantages, substantial initial investments and continuous management are required to ensure effectiveness, and these demands might hinder widespread acceptance. This review emphasizes the critical role of horticulture systems in improving soil carbon levels, soil organic matter dynamics, different forms of carbon, and their overall potential for carbon sequestration.

Hu et al. (2024): Bamboo charcoal application altered the mineralization process of soil organic carbon in different succession stages of karst forest land

Lening Hu, Xuehui Liu, Yaqi Xie, Yicheng Zeng, Huiping OU, Yuefeng You, Tieguang He IN: Forntiers in Environmental Science 12, 1411122, https://doi.org/10.3389/fenvs.2024.1411122

As a soil amendment, Bamboo charcoal helps to contributes to the improvement of soil carbon sequestration, but its effect on the accumulation and transformation of different soil organic carbon in soil of karst forests is not clear. In this paper three distinct forest land succession stages were analysed in ordert to study the charcteristics of SOC mineralization, different carbon fractions of organic carbon, and soil enzyme activities.

Kaur et al. (2024): Quantifying the carbon sequestration potential of different soil management practices aimed at increasing organic content in soil and reducing the usage of chemical inputs

Mandeep Kaur, N Nagabhooshanam, Prashant Sharma, Satyendra Singh, RVV Krishna IN: Global NEST Journal, 26, https://doi.org/10.30955/gnj.05932

This research focuses on quantifying the carbon sequestration potential of diverse soil management techniques aimed at increasing organic content in soil while minimizing the use of chemical inputs. It integrates a multidisciplinary approach, conducting field experiments across diverse agroecological regions with different soil types and cropping systems. Key practices under investigation include cover cropping, crop rotations, conservation tillage, compost application, organic amendments, integrated pest management (IPM), and precision agriculture. The study assesses their impact on soil organic carbon levels, greenhouse gas emissions, soil health indicators, and crop productivity through comprehensive data collection and analysis techniques. Statistical analyses and modeling are employed to quantify carbon sequestration rates, evaluate treatment effects, and assess environmental and agronomic benefits.

Li et al. (2024): Estimation methods of wetland carbon sink and factors influencing wetland carbon cycle: a review

Lixin Li, Haibo Xu, Qian Zhang, Zhaoshun Zhan, Xiongwei Liang & Jie Xing IN: Carbon Research, 3, https://doi.org/10.1007/s44246-024-00135-y

In current studies, most research has focused on the impact of individual factors on wetland carbon sinks, often ignoring the interaction between various factors, which further leads to uncertainty in wetland carbon measurements. This paper aims to elucidate the process of the wetland carbon cycle, summarize the factors affecting wetland carbon sinks, and explore the interplay between various factors and their influence on wetland carbon sinks, aiming to provide theoretical support for the study of wetland carbon sinks. Additionally, this paper reviews the advantages and disadvantages of current wetland carbon measurement methods, proposes research directions for combining machine learning methods, identifies existing difficulties in current wetland carbon measurement, and offers suggestions to serve as a reference for future wetland carbon sink estimation and wetland management.

Budai et al. (2024): Qualitative evaluation of nine agricultural methods for increasing soil carbon storage in Norway

Alice E. Budai, Daniel P. Rasse, Thomas Cottis, Erik J. Joner, Vegard Martinsen, Adam O’Toole, Hugh Riley, Synnøve Rivedal, Ievina Sturite, Gunnhild Søgaard, Simon Weldon, Samson Øpstad IN: European Journal of Soil Science, https://doi.org/10.1111/ejss.13493

In Norway, where soils have relatively high carbon content because of the cold climate, adapting management practices that prevent the loss of carbon to the atmosphere in response to climate change is also important. This work presents an overview of the potential for carbon sequestration in Norway from a wide range of agricultural management practices and provides recommendations based on certainty in the reported potential, availability of the technology, and likelihood for implementation by farmers.

Yu et al. (2024): Soil acidification enhanced soil carbon sequestration through increased mineral protection

Mengxiao Yu, Ying-Ping Wang, Qi Deng, Jun Jiang, Nannan Cao, Xuli Tang, Deqiang Zhang, Junhua Yan IN: Plant Soil, https://doi.org/10.1007/s11104-024-06608-8

As a significant land carbon sink, highly acid subtropical forests in southern China continued to accumulate a significant amount of soil carbon under elevated acid deposition, yet the mechanism of how soil organic carbon and its two components: particulate and mineral-associated organic carbon increased remain unclear. This paper aims to assess which mechanism and drivers dominated the accumulation of SOC and its two fractions under elevated acid deposition.

Chapter: Impact of Rice Husk Biochar on Soil Carbon Sequestration, Methane Emission, and Rice Yield in Wetland Soil (Ultisol)

Kamala Rajalekshmi, Betty Bastin, Sandeep Sasidharan IN: Reducing Carbon Footprint – Microscale to Macroscale, Technical, Industrial and Policy Regulations, 2024, DOI: 10.5772/intechopen.1005103

Rice husk biochar (RHB), produced from the pyrolysis of rice husk (RH), has a higher nutritious value than biochar made from wood. A field research was conducted to evaluate the short-term implications of RHB-derived nutrient translocation and distribution in rice crop, as well as their effects on soil nutrients, rice productivity, and methane (CH4) emissions in wetland Ultisol. The treatments included applying four organic fertilizers: rice husk biochar, daincha (Sesbania aculeata), jack tree (Artocarpus heterophyllus) leaves, and farm yard manure (FYM) at rates of 35 (N1), 70 (N2), and 105 (N3) kg N ha−1.

Aguilera-Huertas et al. (2024): Intercropping in rainfed Mediterranean olive groves contributes to improving soil quality and soil organic carbon storage

Jesús Aguilera-Huertas, Luis Parras-Alcántara, Manuel González-Rosado, Beatriz Lozano-García IN: Agriculture, Ecosystems & Environment, 361, 108826, https://doi.org/10.1016/j.agee.2023.108826

The objective of this study was to evaluate in the short term (3 years) the effect of alley cropping with minimum tillage versus conventional tillage in a traditional rainfed olive grove on soil organic carbon, total nitrogen concentrations, and stocks. Changes in soil quality through a stratification index, and the success of the 4‰ strategy in these soils with this type of management were also evaluated. Three intercropping strategies were tested: Crocus sativus (D-S), Vicia sativa and Avena sativa in rotation (D-O), and Lavandula x intermedia (D-L), all with minimum tillage versus olive with conventional tillage without intercropping, which was used as a control.
