Summary: This study investigated the impact of soil organic carbon (SOC) and aggregates interaction on carbon sequestration during reforestation in degraded red soil. The results showed that after reforestation, the SOC stock increased by 131.28-140.00%. Coniferous and broad-leaved mixed forests had the highest proportion of macroaggregates and higher SOC accumulation, indicating their greater potential for carbon sequestration.

Summary: Soil degradation poses a global threat to agricultural crop production. To combat this issue, various carbon-rich amendments (CRAs) have been used to improve soil quality. However, the influence of different CRAs on overall soil quality remains poorly understood. This study examined the effects of straw-C, composted straw-C, and humic acid-C on soil quality and tomato yields in two field sites with different nutrient-holding capacities.

Summary: Rubber roots host a diverse community of arbuscular mycorrhizal (AM) fungi, with the genus Glomus representing a large percentage. Rubber genotype does not significantly impact AM fungal communities, but the composition of these communities can vary between old and young rubber plantations. The diversity of AM fungi in rubber roots is crucial for restoring degraded soils.

Summary: The study compared soil C and N sequestration between artificial forests and natural grasslands converted from sloping cropland in the Central Loess Plateau, China, over 20 years post-implementation of the Grain for Green Program. The results showed that both vegetation restoration types significantly increased the soil organic carbon and nitrogen content in the top 60 cm of soil, with artificial forests having higher sequestration capacities. Soil aggregate stability and the quality of input organic matter were found to be crucial in affecting soil C and N sequestration post-restoration, with N fixing species enhancing sequestration.

Summary: Agricultural intensification has led to severe degradation of croplands in China. Converting degraded croplands to grasslands can increase soil organic carbon and nitrogen content, but may decrease soil pH and available phosphorus. The duration of conversion and mean annual precipitation are major factors influencing soil changes.

Summary: Sewage sludge (SS) is widely used as a soil conditioner due to its high content of organic matter and nutrients. This study found that cyanobacteria growth increased in soil amended with low concentrations of composted SS, while higher SS concentrations decreased cyanobacteria growth. However, SS significantly enhanced soil organic carbon gain and tightly-bound exopolysaccharide content. Cyanobacteria inoculation improved soil stability and had the potential for salt immobilization and soil bioremediation.

Summary: The study evaluated the effectiveness of desalinization via freshwater restoration in coastal wetlands by analyzing microbial communities and activities. The results showed that freshwater input significantly increased soil organic carbon content and improved microbial diversity and functions in restored wetlands. The recovered microbial diversity and abundance of specific bacteria in restored wetlands were similar to those in original freshwater wetlands.

Summary: Organic amendments significantly increased soil organic C stock in saline paddy fields, with biochar treatment showing the highest increase. However, rice straw and organic fertilizer were found to be more effective in improving soil aggregate stability compared to biochar. This research highlights the importance of organic amendments in enhancing soil quality and carbon sequestration in saline-alkaline soils.

Summary: The impacts of natural restoration projects on soil microbial carbon cycling functions have not been well recognized. In this study, metagenomic sequencing was used to analyze the changes in soil microbial C cycling potentials at three restoration stages. The results showed that natural restoration altered soil microbial C cycle functions by enhancing C decomposition potentials and causing shifts in microbial composition.

Summary: This study assessed the changes in aboveground C and soil organic C (SOC) stocks in degraded and recovering wetlands in the Yellow River Delta. The results showed that recovering wetlands had higher aboveground C and SOC stocks compared to degraded wetlands, mainly due to improved soil water, salinity, and nutrient conditions. Plant-soil interaction played a crucial role in driving wetland ecosystem C stocks in degraded and recovering wetlands.

Summary: Soil erosion has significantly decreased on the Loess Plateau due to the implementation of soil and water conservation practices. This study analyzed the changes in vegetation cover and identified the distribution of terraces using remote sensing images. The results showed that vegetation restoration and terraces have played an important role in reducing soil erosion.

Summary: The study shows that the tree species used for reforestation in postfire sites play a crucial role in determining the properties of regenerating soils and restoring ecological functions. Among the tree species studied, common birch had the most pronounced effect on soil properties, which is particularly noteworthy as it appeared through spontaneous succession.
