Summary: This study reveals that damming of rivers alters the spatial distribution of carbon in sediments, leading to higher CH4 and CO2 concentrations upstream compared to downstream. During reservoir impounding periods, CH4 diffusive flux is higher upstream than downstream, while CH4 emissions are predominantly by ebullition, with significantly higher flux downstream during discharging periods. The increase in TOC in downstream sediment is attributed to riparian zone soil erosion caused by water level fluctuations.

Summary: This study conducted a large-scale survey of 23 major rivers in northern Quebec, finding significant variations in the concentrations of different carbon species, with methane showing the greatest variability. The study also found that the concentration of dissolved organic carbon decreased with an increase in water surface coverage, suggesting that it may primarily originate from water-land interfaces. Furthermore, for heavily dammed rivers, carbon emissions to the atmosphere approached the carbon export component. These findings are crucial for accurately quantifying carbon cycling in boreal rivers, understanding the sources and sinks of carbon, and predicting their responses to anthropogenic pressures and dynamic climate conditions.

Summary: The study found that rice acted as a reducer of N2O emissions in paddy fields, not an emission source. This was influenced by the rhizospheric activities of rice plants and the level of N fertilization, which affected the N2O flux. The differences in N2O fluxes between rice-planted and non-planted soils were likely due to the N2O consumption potential influenced by these factors.

Summary: Conventional tillage (CT) degrades soil and environmental quality, while conservation agriculture, like reduced tillage, can play a significant role in reducing greenhouse gas emissions and maintaining soil organic carbon storage. This study conducted at the Bangladesh Agricultural Research Institute (BARI) evaluated the impact of CT and strip tillage (ST) on greenhouse gas emissions, global warming potential, and net soil organic carbon variations in a rice-mustard-rice cropping system. The findings showed that ST significantly reduced methane emissions, greenhouse gas intensity, and global warming potential compared to CT. Additionally, ST increased net ecosystem CO2 absorption and rice equivalent yields. These results highlight the importance of adopting strip tillage practices in Asian countries to minimize soil carbon loss and reduce greenhouse gas emissions.

Summary: Overfertilization is common in rainfed apple orchards on China's Loess Plateau, but its impacts on soil physicochemical properties in deep soil profiles are poorly understood. This study found that different land-use types showed divergent distribution patterns in soil properties, with low variability for SWC and pH, moderate variability for NH4+-N, AP, and AK, and high variability for SOC, NO3--N, and EC. The results also showed that fertilization influenced soil water content, NO3--N, AP, and AK, and NO3--N played a crucial role in regulating pH and EC. Soil profiles were useful for studying the evolution of soil quality.

Summary: The Mediterranean region is expected to experience more intense rainfall events and severe droughts due to climate change, leading to an increase in runoff and erosion rates in agrosystems. Vegetation cover can help reduce erosion and the soil seed bank can provide cost-effective vegetation. This study assessed the effect of vegetation cover on seed loss in vineyards and evaluated the differences in the soil seed bank along a transect. The results suggest that vegetation may not protect interrows from runoff-induced seed loss.

Summary: This research introduces a hybrid four-sub-deep neural network (HFSD) model for partitioning NEE into GPP and ER. The HFSD employs dual sub-deep neural networks to estimate ERa and ERb and incorporates GPP and environmental variables to predict vegetation transpiration. The results of the model show that the dual sub-DNNs architecture enhances the accuracy of ER simulations, while using EC-derived T as a constraint improves the accuracy of GPP simulations. Correlation analyses suggest that solar radiation and air temperature primarily influence the seasonal variations in GPP and ER, while soil moisture has a strong impact during dry seasons. This study advances the biophysical description of data-driven models for NEE partitioning and enhances the accuracy of GPP and ER estimates.

Summary: Considerable advances have been made in the assessment and mapping of soil organic carbon stocks. However, the rates of change in carbon stocks are influenced by various factors and need to be quantified. This study found that sandy soils under cultivation and forests have different organic carbon stocks. Factors such as tillage, irrigation, and nitrogen applications contribute to the decline in soil organic carbon stocks. Afforestation of abandoned cultivated fields can increase soil organic carbon, but it is still lower than soils under forest that have never been cultivated.

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.
