Summary: Soils are the largest terrestrial pool of organic carbon, and the mechanisms by which SOC is stored in subsoils are affected by land use. This study found that woodland land use led to a higher content of mineral-free particulate organic matter (fPOM) in both topsoil and subsoil, while the mineral-associated organic carbon (MinOC) was proportionally higher in the subsoil under all land uses. These findings suggest that land use affects SOC protection, with woodlands containing less protected carbon.

Summary: Tackling the global carbon deficit through soil organic carbon sequestration in agricultural systems has been a recent focus. However, there is still a lack of comprehensive understanding of on-farm SOC sequestration potentials in order to derive effective strategies.

Summary: This study analyzed changes in soil organic carbon (SOC) stock up to 30 years after afforestation of agricultural land in Lithuania, showing that different soil types have varied impacts on SOC after afforestation with different tree species.

Summary: The study reveals that soil organic carbon concentrations are highest in Southeast Australia, but may decrease in the future due to the extension of arid climate conditions. Temperature, elevation, and vegetation index are identified as the significant drivers of SOC concentrations.

Summary: This study used the Land Use and Carbon Scenario Simulator (LUCAS) to model the ecosystem carbon cycle in the Nisqually River watershed and found that total ecosystem biomass carbon increased while total ecosystem soil carbon declined from 1985 to 2017 due to land cover changes. The study also revealed that different land cover types showed varying trends in carbon changes, with some losing carbon through erosion and others gaining carbon through deposition.

Summary: Adopting regenerative agriculture practices, such as cover cropping and ley-arable systems, can increase soil organic carbon concentration and potentially contribute to mitigating climate change. However, reduced tillage intensity does not have a significant impact on soil carbon stocks. Implementing regenerative agriculture practices in Great Britain is important for achieving net zero greenhouse gas emissions in the agricultural sector.

Summary: The abandonment of agricultural land has significant impacts on the environment and society. By combining field monitoring data and literature analysis, this study investigated the factors influencing plant species variability in abandoned land. 81 plant species and 23 botanical families were identified over 27 years of land abandonment. The results showed positive effects of land abandonment on soil fertility, including increased soil organic carbon concentration and stocks.

Summary: The EU Soil Strategy 2030 aims to increase soil organic carbon (SOC) to enhance soil health and offset greenhouse gas emissions. The study found that land use and changes were the main drivers of SOC changes, with converting cropland to grassland leading to the highest positive change in SOC. However, local soil and environmental conditions can affect the effectiveness of converting cropland to grassland.

Summary: Revegetation in the Mu Us Sandy Land led to a substantial increase in soil organic carbon density and inorganic carbon density, as well as enhancements in total nitrogen, available potassium, and other nutrients. These factors played crucial roles in promoting carbon sequestration in the soil during afforestation with shrubs and arbors.

Summary: The study evaluated soil organic carbon, nitrogen stocks, and physico-chemical soil parameters in eight provinces of Gabon, focusing on different land use systems and soil types. The results showed that the soil texture was dominated by sand and clay, and the soil pH was acidic.

Summary: Grazing exclusion is a widely implemented strategy for restoring degraded grassland ecosystems and increasing carbon stocks. This study analyzed data from 199 experiments to understand the temporal responses and factors influencing plant and soil carbon stocks following grazing exclusion in different grassland ecosystems. The results showed that plant biomass carbon stocks and soil organic carbon stocks decreased exponentially or rationally with years since enclosure. Grazing exclusion had positive effects on aboveground biomass carbon, but the effects on belowground biomass and soil carbon were influenced by climate, initial carbon levels, and grazing exclusion duration. The response of carbon stocks to grazing exclusion stabilized after approximately 40 years, with soil carbon sequestration showing a lagged pattern compared to plant biomass carbon. The study highlighted the effectiveness of grazing exclusion in regions with low carbon content and non-water limited conditions. However, it might not be an effective measure to increase soil organic carbon stocks in water-limited areas like desert grasslands.

Summary: Fires have a direct impact on soil properties and can lead to soil degradation. Climate change-induced droughts and elevated temperatures are increasing the severity, extent, and frequency of fires, posing a threat to soil function and ecosystem services. This study assessed the effects of the 2019-2020 fire season in Kangaroo Island, Australia, on dry sclerophyll woodland and the interaction between the fire and historical land use on post-fire soil function.

Summary: Soil Bulk Density (BD) is an important variable for site characterization and policy development. This study integrated BD sampling data with coarse fragment data to improve accuracy in estimating soil organic carbon (SOC) stock. The results showed that computing SOC stock with coarse mass fraction leads to underestimation, especially in woodlands and shrublands.

Summary: Rhizosheaths are aggregated, sheath-like soils that physically adhere to root surface, and they have distinct soil organic carbon (SOC) signatures from rhizosphere soils of non-rhizosheath forming plants. The molecular characteristics of rhizosheath SOC, including more root inputs of labile substrates and relatively recalcitrant compounds, as well as its temporal dynamics, suggest a critical role of rhizosheath in shaping the rhizosphere microenvironment and regulating SOC cycling.
