Summary: The age of mangrove forests has a significant effect on carbon additionality and carbon accretion rate, with older mangrove stands holding greater carbon stocks and higher soil sequestration rates. However, age also affects soil carbon fluxes, with older mangroves releasing less methane emissions but higher CO2 flux compared to young stands. This suggests that the carbon sink capacity of restored mangrove forests increases with age but stabilizes once they mature.

Summary: This study used a boosted regression trees (BRT) model to map the saturated soil organic carbon (SOC) and its density in cultivated lands in Northeast China. The spatial variation of SOC sequestration potential was also calculated based on the difference between saturated SOC and SOC density. The results showed that climate, topography, lengths of cultivation data (LCD), and soil samples significantly influenced the distribution of SOC and its density.

Summary: This study investigates the relationship between mineral composition and soil organic carbon (SOC) in different regions of China. Results show that SOC is mainly stored as mineral-associated organic carbon (MAOC), and its stability depends on the composition of the host minerals. Aromatic C is also found to play an important role in SOC stabilization. The study suggests that mineralogy and specific organic carbon fractions are key factors in SOC protection.

Summary: The study found that increasing precipitation promotes organic C sequestration in deep soils, and apple orchards have a greater capacity for SOC sequestration compared to arable lands. The SOC sequestration in deep soils for MAP = 422 mm was almost twice as great as that for MAP = 606 mm. Additionally, lower precipitation leads to higher efficiency of SOC sequestration in deep soils.

Summary: Understanding soil organic carbon (SOC) stocks and carbon sequestration potential in cultivated lands is crucial for mitigating climate change. This study predicted SOC levels and sequestration potential in cultivated lands in China using point measurements and environmental variables. The results showed higher SOC levels in northeast China and lower levels in central China. China's cultivated lands have the potential to sequester a significant amount of organic carbon, with regional variations. The primary environmental factors influencing SOC levels were mean annual temperature, clay content, and normalized difference vegetation index.

Summary: In this study, biochar was prepared using waste dander and CaSa(4) was generated on its surface to enhance soil carbon sequestration ability. The results showed that the application of Ca-BC reduced soil organic carbon mineralization rate, increased soil moisture content and organic carbon content. Bioinformatics analysis also revealed a shift in bacterial phyla with the application of Ca-BC.

Summary: Wetland restoration is a common strategy for improving water quality in agricultural catchments, but the ability of wetlands to retain phosphorus varies widely and they can sometimes act as a source of phosphorus. Through meta-analysis, we found that wetlands are often sinks for phosphorus, but the retention efficiency differs depending on the form of phosphorus and the specific wetland. The release of phosphorus from wetlands is influenced by factors such as hydraulic loading rates, influent phosphorus concentration, and soil/sediment phosphorus. Our results emphasize the importance of restoring wetlands for phosphorus retention and suggest strategies for enhancing retention and avoiding release.

Summary: To accurately assess soil organic carbon (SOC) stocks in agroecosystems, sampling strategies should consider topographic variability and soil redistribution through erosion and deposition. This study used digital elevation models (DEMs) to determine primary terrain attributes for guiding sampling in cultivated fields and nearby grasslands. Results showed that digital terrain attribute values were important for predicting SOC stocks in both cropland and grassland soils, with profile and planform curvature being significant factors. The study also found that soil movement can explain SOC variability in upland soils.

Summary: The degradation of peatlands contributes significantly to global carbon dioxide emissions, making the restoration of disturbed and degraded peatlands crucial for climate change mitigation. However, the resilience of restored peatlands to climate change and disturbances is not well-understood. While restoration efforts can achieve net carbon sequestration, the restoration of biodiversity, hydrological regime, and peat soil structure may not be fully achieved, potentially compromising ecosystem resilience to future disturbances.

Summary: In hardwood floodplain forests, significant relationships exist between soil organic carbon (SOC) stocks and hydromorphic features, soil texture, C/N ratio, pH, and forest age. The complexity of interactions among heterogeneous microrelief, anthropogenic effects, and hydrologic situation make it challenging to predict SOC stocks accurately without field validation. Profiling the controlling factors for SOC storage in these environments suggests that relief and sedimentation proxies are the strongest factors influencing SOC stocks, while vegetation plays a subordinate role.

Summary: Cover crops can improve soil health and increase soil carbon sequestration, benefiting both climate adaptation and mitigation. A global meta-analysis of 93 studies found that cover crops increased soil organic carbon (SOC) by 12% and increased several SOC fractions, including microbial biomass carbon (MBC), dissolved organic carbon (DOC), particulate organic carbon (POC), light-fraction organic carbon (LFOC), permanganate oxidizable carbon (POXC), short-term mineralizable carbon (SMC), and mineral-associated organic carbon (MAOC). Soil taxonomic order and experimental duration were key factors influencing the effect of cover crops on SOC fractions.

Summary: Wetland restoration is a common practice to offset the loss of natural wetlands due to human interference. While researchers often compare bird, amphibian, and reptile communities in restored and natural wetlands, they tend to overlook small mammals. However, small mammals play a crucial role in the ecosystem as seed dispersers and prey for larger wildlife. A study conducted in West Virginia, USA, found that restored wetlands provided sufficient habitat for small mammal communities, but the abundance of certain species differed between restored and natural wetlands.

Summary: The voluntary carbon market for agricultural soil carbon sequestration is growing fast, but there is uncertainty regarding the equivalency of carbon credits generated in different programs due to inconsistent protocols. Scientists have a crucial role to play in guiding protocol development and conducting relevant research.

Summary: This study compared the rhizospheric microbiomes of Dongxiang common wild rice (CWR) and Leersia hexandra Swartz (LHS) and found that CWR had a less diverse microbiome but a higher proportion of cold-tolerant microbial groups. It suggests that the cold tolerance of CWR may be associated with specific microbial groups rather than microbial diversity.

Summary: This study investigated the changes in soil microbial communities following rice cultivation on saline-sodic soils using high-throughput sequencing. The results showed that soil fungi and bacteria became more diverse and abundant after rice cultivation, indicating the amelioration of saline-sodic soil. The processes of microbial succession following rice cultivation could be divided into two stages and were influenced by different factors for bacteria and fungi.

Summary: Peatland restoration is important for soil carbon sequestration and climate change mitigation, but successful outcomes require understanding of the soil ecological processes. This study compared soil properties, enzyme activities, and bacterial and archaeal communities in rewetted and natural peatlands. Results showed significant differences between these two types of peatlands. Increasing water levels in rewetted peatlands shifted soil properties and enzymatic activities towards natural peatlands. However, enzymatic activities exhibited opposite trends with increased water levels in the two types of peatlands. Differences in pH and nutrient conditions may contribute to the biological differences between rewetted and natural peatlands, hindering restoration after rewetting. Therefore, it is important to consider measures that promote a nutrient-limited and acidic environment for effective peatland restoration.
