Tree planting patterns play a critical role in influencing soil organic carbon (SOC) dynamics and carbon(C) sequestration potential in forest ecosystems. This study investigated the effects of different planting methods on C stocks in Picea crassifolia plantations located in the shallow mountainous region of the Qilian Mountains, northwest China. Fifteen sample plots were established across five plantation types to quantify biomass, SOC content, and carbon storage in vegetation and soil layers.

Glacier retreat in northern latitudes exposes new landscapes that may develop soils and ecosystems, which in turn may sequester carbon and serve as a negative climate change feedback. Proglacial soil development and landscape evolution were investigated using transects from three high-latitude glacial systems. Soil samples were analysed for organic carbon (OC) concentration, bacteriohopanepolyol biomarkers (BHPs, membrane lipids that trace major microbial groups), and 16S rRNA gene sequencing.

The form in which soil organic carbon (SOC) is stored determines its capacity and stability, commonly described by separating bulk SOC into its particulate- (POC) and mineral-associated (MAOC) constituents. MAOC is more persistent, but the association with mineral surfaces imposes a maximum MAOC capacity for a given fine fraction content. Here, the authors leverage SOC fraction data and spectroscopy to investigate POC/MAOC distribution, together with SOC changes data over 2009–2018 period, across pedo-climatic zones in the European Union and the UK.

With the growing importance of adopting biofertilizers management and crop residue addition to combat sustainability issues and carbon (C) sequestration, the present study was conducted in a 12 years long-term rice–wheat cropping system. The study aimed to evaluate the effect of tillage, crop residue, and biofertilizers on C sequestration and different sensitive C pools in the acid alluvial soil of the lower Indo-Gangetic plain of India. For comparison, 3rd and 12th cropping cycle data of eight treatment combinations [tillage (zero tillage (ZT) and conventional tillage (CT)), crop residues, and biofertilizers application] were used. Soil sampling after wheat crop harvest was done at two layers 0–5 cm and 5–20 cm.

There is a lack of understanding of which plant traits to target for SOC enhancement or the ultimate sequestration potential of such measures. Existing long-term common gardens of genetically diverse plant populations may provide an opportunity to evaluate biological controls on SOC outcomes, separate from environmental or management variability. Here the authors report on soil carbon and root chemical data collected for 24 genotypes within a 13-year-old common garden in northwestern Oregon planted with over a thousand natural variants of Populus trichocarpa. Fractionating surface soil (0–15 cm) revealed substantial variation in stocks of mineral-associated organic matter (MAOM; 18–67 tonnes C/ha) and particulate organic matter (POM; 2–22 tonnes C/ha).

Sustainable Soil Systems in Global South, https://doi.org/10.1007/978-981-97-5276-8_14
The roles of microbes and biological matter in enhancing soil carbon sequestration in the Global South are explored in this chapter. The chapter begins by providing an introduction to the significance of soil carbon sequestration and the specific focus on microbial communities and biological matter. Understanding the dynamics of soil carbon sequestration and the factors influencing it forms the foundation for effective strategies. The authors discuss the current challenges and opportunities faced in the Global South regarding soil carbon sequestration and highlight the urgent need for sustainable solutions. Microbes, such as bacteria and fungi, are key players in carbon cycling and storage. The authors delve into the intricate interactions between soil microbial communities and plant roots and emphasize their contribution to carbon sequestration. They explore microbial processes involved in organic matter decomposition, nutrient cycling, and the formation of stable soil organic carbon.

This study adopts a critical research approach to review existing ERW experiments, focusing on the mechanisms of soil improvement and CO₂ sequestration, as well as the economic costs and environmental risks associated with its large-scale implementation. The results demonstrate that while ERW effectively enhances soil pH and provides essential nutrients for crops, its CO₂ sequestration capacity is highly dependent on variables such as soil type, rock type, application rate, and particle size.

This study was designed to investigate the impact of different return-to-field methods of rice straw on the transformation between different carbon components in the soil of Siraitia grosvenorii fields. The authors hypothesize that rice straw and its biochar, as soil amendments, can influence the transformation and cycling of different carbon components in the soil of S. grosvenorii fields through various return-tofield methods. Rice straw, rice straw biochar, and „rice straw + rice straw biochar“ were applied as additives in a 2-year field experiment.

Fertilization, an important component of agricultural management, is a significant factor influencing soil carbon sequestration. This study analyzed literature from the Web of Science from 2008 to 2024 using CiteSpace. It provides a comprehensive overview of the role of fertilization in soil carbon sequestration, providing important insights for improving soil carbon sequestration strategies.
