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.

Ashes to ashes, carbon to soil: A cost-benefit analysis of abatement measures to increase soil carbon-sequestration capacity

This study examines five soil improvement measures — three crop management practices (cover cropping, no tillage and use of green manure) and two broader land restoration techniques (agroforestry and sustainable forest management) — that can enhance soil quality, in six countries: Germany, France, the Netherlands, Italy, Spain and the UK. All these measures contribute to preventing soil erosion, enhancing carbon sequestration, and improving biodiversity.

Meena et al. (2024): Agriculture models for restoring degraded land to enhance CO2 biosequestration and carbon credits in the Vindhyan region of India

Ram Swaroop Meena, Gourisankar Pradhan, Kanchan Singh, Sandeep Kumar, Ambuj Kumar Singh, K.S. Shashidhar, Krishan Kant Mina, Ch. Srinivasa Rao IN: Science of The Total Environment, 929, 172661, https://doi.org/10.1016/j.scitotenv.2024.172661

The study’s objective was to evaluate the status of converted degraded land into productive agricultural models by improving the physicochemical properties of the soil, soil organic matter (SOM), soil organic carbon (SOC) fractions (active and passive), and microbial biomass carbon (MBC), while also generating carbon (C) credit for additional farmers’ income. Six models were analyzed.

Mattila & Vihanto (2024): Agricultural limitations to soil carbon sequestration: Plant growth, microbial activity, and carbon stabilization

Tuomas J. Mattila, Noora Vihanto IN: Agriculture, Ecosystems & Environment, 367, 108986, https://doi.org/10.1016/j.agee.2024.108986

The aim of this study was to survey the challenges and limitations found on pioneering farms testing C sequestration using a Finnish network of farmers testing carbon farming practices. A combination of satellite monitoring, on-site measurements and soil analysis was used to quantify and evaluate soil physical, chemical, and biological quality indicators and plant productivity on 20 farms (40 fields). The indicators were assessed through a conceptual C sequestration model, classifying them into limitations for three stages of plant growth, microbial activity or C stabilization.

Soinne et al. (2024): High organic carbon content constricts the potential for stable organic carbon accrual in mineral agricultural soils in Finland

Helena Soinne, Matti Hyyrynen, Medilė Jokubė, Riikka Keskinen, Jari Hyväluoma, Sampo Pihlainen, Kari Hyytiäinen, Arttu Miettinen, Kimmo Rasa, Riitta Lemola, Eetu Virtanen, Jussi Heinonsalo, Jaakko Heikkinen IN: Journal of Environmental Management, 352, 119945, https://doi.org/10.1016/j.jenvman.2023.119945

The authors used agronomic soil test results representing c. 95% of the farmed land area in Finland to estimate the potential of the uppermost 15 cm soil layer of mineral agricultural soils to sequester organic carbon (OC) and to contribute to the mitigation of climate change. The estimation of the maximum capacity of mineral matter to protect OC in stable mineral-associated form was based on the theory that clay and fine-sized (fines = clay + silt) particles have a limited capacity to protect OC. In addition, they used the clay/OC and fines/OC ratios to identify areas with a risk of erosion and reduced productivity, thus indicating priority areas potentially benefitting from the increased soil OC contents.

Zhang et al. (2023): Estimating Soil Carbon Sequestration of Jatropha for Sustainable Aviation Fuel Pathway

Zongwei Zhang, Junqi Li, Zihan Wang, Haonan Liu, Keheng Wei IN: Water, Air & Soil Pollution 235, 47, https://doi.org/10.1007/s11270-023-06832-5

The sustainable aviation fuel raw material planting process will inevitably cause carbon emissions from induced land use change. However, limited by the regional specificity of energy plants, the ILUC emissions value of SAF is less considerable in the case of soil carbon sequestration during the raw material planting process. Therefore, this study used the CENTURY model to predict the carbon sequestration of soil in Jatropha plantations and compared it with the preparation of aviation fuel from soybean oil.

Chen et al. (2023): Trade-off between soil carbon sequestration and net ecosystem economic benefits for paddy fields under long-term application of biochar

Zhuoxi Chen, Shuo Han, Zhijie Dong, Hongbo Li, Aiping Zhang IN: GCB-Bioenergy, https://doi.org/10.1111/gcbb.13116

Here, the life cycle assessment method was used to quantify the carbon footprint (CF) and net ecosystem economic benefits (NEEB) of paddy fields under different biochar and nitrogen fertilizer application rates in 7 years. Three biochar rates of 0 (B0), 4.5 (B1) and 13.5 t ha−1 year−1 (B2) and two nitrogen fertilizer rates of 0 (N0) and 300 kg ha−1 year−1 (N) were set.
