Summary: This study investigates the effects of land use changes on soil organic carbon (SOC) stocks and simulates these changes using the RothC model. The results show that SOC stocks are highest in secondary forests and lowest in oil palm plantations. Climate change projections indicate that future SOC stocks will be affected differently based on land use and carbon input from vegetation. The model predicts that SOC stocks will increase, but the rate of change varies depending on land use, plant species, and land management practices.

Summary: The conversion of forest to agriculture in higher latitude regions like northern Ontario, Canada is expected to increase due to warming. Minimizing soil organic carbon (SOC) loss is crucial, but there is limited understanding of best land management practices. This study measured changes in SOC after land conversion and used a model to assess the impacts of climate change on crop yields and SOC stocks. The findings highlight the potential role of pasture and crop diversification in avoiding SOC losses induced by climate-warming.

Summary: Carbon sequestration in soils and plant biomass is seen as an important means to mitigate climate change. However, it is influenced by climate warming, nutrient limitations, and local land use. A study conducted in the UK revealed that realistic targets for grassland restoration and afforestation can enhance carbon sequestration potential by an additional 120 TgC, but this is conditional on climate change being controlled below 2 degrees Celsius. Conversely, arable expansion would decrease carbon storage. The study concludes that concerted land use change can contribute to national-level carbon sequestration, but it is dependent on global reductions in emissions from fossil fuels, deforestation, and soil degradation.

Summary: This study examines the impact of converting forestland to agricultural land on soil organic carbon (SOC) stocks and soil erodibility in the Mae Chaem Basin, Chiang Mai Province, Thailand. The results show that the conversion to maize fields leads to a significant reduction in SOC stocks, while the replacement of maize fields with grassland and pumpkin tends to increase SOC stocks. Additionally, the study finds a positive correlation between silt concentration and soil erodibility, and a negative correlation between SOC and soil erodibility.

Summary: Land Use Change (LUC), especially deforestation in tropical regions, significantly contributes to global anthro-pogenic greenhouse gas (GHG) emissions. In this study, the potential combined impacts of LUC and Climate Change (CC) on Soil Organic Carbon (SOC) stocks in the Ethiopian highlands were investigated. The study found that most of the tested combinations of LUC and CC led to losses of SOC stocks, with deforestation being the biggest threat to SOC stocks. The study recommends conservation of natural forests and longer rotation periods for Eucalyptus plantations to preserve SOC stocks.

Summary: Rural land use patterns in southern China have undergone significant changes, affecting the release and fixation of carbon and nitrogen in paddy soil. This study examines the impact of different land use patterns on soil carbon and nitrogen, highlighting the loss rates of organic carbon and total nitrogen under abandonment, dry-farming, and fish-farming. The changes in land use driven by rising labor cost and market demand have reduced soil carbon sequestration ability. The promotion of sustainable farming practices and nitrogen management is crucial to meet China's resource constraints and carbon neutrality goals.

Summary: Choosing appropriate multivariate calibration and preprocessing transformation techniques is crucial in determining soil organic carbon (SOC) content based on visible and near-infrared (Vis-NIR) spectroscopy. Support vector machine regression (SVMR) model combined with first derivatives of reflectance (FDR) provided the best prediction results for SOC content, outperforming partial least-squares regression (PLSR) and wavelet neural network (WNN) models. Using FDR of Vis-NIR spectroscopy with SVMR model is recommended for high-accuracy determination of SOC content.

Summary: Rock fragments can significantly impact soil carbon and nitrogen cycles through physical mechanisms, with soil carbon and nitrogen outputs showing parabolic relationships with rock fragment content when considering soil hydraulic parameters and carbon-nitrogen stocks. The responses are mainly influenced by carbon-nitrogen stocks for soil CO2 emissions, and by soil hydraulic parameters for soil N2O emissions and N leaching. Differences in responses between DNDC and DayCent models highlight the complexity and role of bulk density in simulating soil dynamics.

Summary: This study simulated the hot moments of soil N2O emissions and mineral N leaching in a mixed landscape of tea garden, bamboo forest, and coniferous and broadleaved mixed forests. The results showed that the hot moments mainly occurred during dry years, summer, months with high air temperature, and months after fertilization. Temperature, precipitation, and fertilization were identified as the main factors controlling the formation of hot moments. The tea garden was the concentrated hot spot area, and soil properties such as carbon/nitrogen ratio and slope also influenced the formation of hot moments. Comprehensive consideration of fertilizer management, climate, and soil properties is crucial to alleviate the formation of hot spots and hot moments of N losses.

Summary: This study used a global meta-analysis method to investigate the influence of conversion from conventional tillage to conservation tillage on soil saturated hydraulic conductivity (K-sat). The results showed that factors like soil layer, conservation tillage type, soil texture type, and cropping system management did not significantly affect the influence of conversion to conservation tillage on K-sat. However, the conversion to conservation tillage significantly increased the surface and subsurface K-sat when measured by a rainfall simulator. The relationship between climatic and topographic factors and K-sat responses to tillage conversion was also explored.
