Summary: Mollisols in Northeast China have shown relatively stable soil organic carbon (SOC) stocks over the past few decades, with a trend of accumulation. The implementation of conservation tillage and a slowdown in land reclamation have helped maintain and restore SOC stocks, but severe soil erosion has led to an imbalance in SOC redistribution.

Summary: Ephemeral gullies are important erosion features that lead to significant soil loss and sediment production, mainly influenced by rainfall, slope, tillage, and crop management. Cross-slope cultivated areas are more susceptible to severe erosion compared to areas cultivated up and down the slope, with soybean fields experiencing more serious erosion than corn fields.

Summary: This study compared the effects of straw and biochar application on soil carbon sequestration and fertility conservation. It was found that applying both straw and biochar significantly increased soil organic matter content, labile and humic carbon, and corn yield. Biochar was more effective in stabilizing and accumulating soil organic matter, while straw contributed to improving soil fertility. Co-application of straw and biochar synergistically improved the biological activity and stability of soil organic matter. Therefore, it is recommended to add a small amount of biochar to straw returning practice to enhance soil organic matter stability and activity, and achieve low carbon strategy and fertility conservation.

Summary: The composite fingerprinting approach is valuable for sediment source identification, but few studies have explored its use in catchments with multiple check dams. In this study, sediment sources were identified in an agricultural catchment in Northeast China using optimal fingerprints from different particle size fractions. The results showed consistent sediment contributions based on fine particle size ranges, but inconsistent contributions based on a coarse particle size range. Sediment in check dams was mainly from hillslopes or gully slopes, depending on the particle size and organic correction factors used.

Summary: Soil quality plays a critical role in sustainable agricultural development, especially in regions with thin-layer black-soil coverage that have experienced severe degradation. This study constructed an integrated soil quality index (SQI) using diverse datasets and found that soil degradation was observed in a typical thin-layer black-soil region in China. Black-soil thickness, soil organic matter, and total nitrogen content were strongly correlated with corn yield. The minimum-dataset-based SQI using six soil properties within 0-30 cm was the optimal solution for SQ evaluation. Improving soil quality and managing surface black soil loss are crucial for increasing crop yield in these regions.

Summary: This paper presents a comparative study of sediment budgets for the largest Siberian rivers in Northern Eurasia. The data suggests that sediment sinks and storage in catchment and river networks dominate the sediment budget, leading to a significant decline in sediment transport compared to catchment erosion.

Summary: This study conducted experiments on the Chinese Loess Plateau and found that erosion-induced network of rills and gullies increased flow connectivity, resulting in uniform runoff from the upper hillslope to the headwater outlet. The results suggest that scale-independent runoff is typical of highly degraded slope systems.

Summary: The study showed that integrated catchment management is crucial for controlling soil erosion. Effective catchment management measures can significantly reduce soil loss, but further efforts are needed on certain slopes, especially in gully areas.

Summary: This study utilized a multi-tracer method with rare earth elements to investigate seasonal soil erosion and its spatial distribution, revealing that surface runoff is the primary external erosive force of hillslope soil erosion, which is crucial for understanding soil erosion on long slopes.

Summary: This study examines the potential impacts of climate change on soil erosion in an agricultural catchment in eastern Canada. The Modified Universal Soil Loss Equation (MUSLE) and a hydrological model were used to calculate sediment yields and assess climate sensitivity. Results suggest that conservation and no-till practices could significantly reduce annual sediment yields.

Summary: This study evaluates the impacts of environmental changes on soil erosion and sediment yield in the Merguellil watershed in Central Tunisia over the past forty years. The results show that the combined impact of land use change and soil and water conservation techniques has resulted in a slight decrease in soil erosion and sediment yield. However, the predictions suggest that further degradation of natural vegetation and a reduction in the efficiency of soil and water conservation works may lead to a slight increase in soil erosion and sediment yield.

Summary: In this study, soil erosion in the complex Chenab river basin was estimated using the Revised Universal Soil Loss Equation (RUSLE) and remote sensing (RS) technology. The results underscore the urgent need for enhanced strategies to control and mitigate soil erosion in the region due to severe environmental degradation.

Summary: Long-term tillage practices can alter soil microbial and faunal communities and their relationships, and have significant effects on soil properties. Subsoil tillage is recommended as the optimal practice in Northeast China.
