Summary: The Paris Agreement aims to achieve net-zero emissions, requiring decarbonization technologies in agriculture. Agri-waste biochar shows significant potential for reducing carbon emissions in agricultural soils. A study conducted in the Indo-Gangetic Plains compared different residue management methods and nitrogen options for emission reduction and carbon capture. The results showed that biochar application significantly reduced CO2, CH4, and N2O emissions compared to other management methods, and had a lower global warming potential and carbon footprint. Biochar-based approaches have great potential for carbon offset and improving soil carbon in rice-wheat cropping systems.

Summary: This study investigated the impact of different straw management practices on soil humic substances and aggregate-associated humic substances. The results showed that both biochar and straw improved soil aggregate stability and humic carbon content. Straw returning was an effective method for enhancing soil organic carbon and humic substances. Biochar amendment increased soil aggregate stability, humic carbon content, and stability of organic carbon over the span of eight years. These findings suggest that biochar can be a useful approach for carbon sequestration and improving soil quality.

Summary: This study predicts the long-term transport of heavy metals at an abandoned e-waste recycling site, considering historical pollution activities, land use, and metal pollution dynamics. The results show severe heavy metal contamination in the soil profiles, with copper and zinc primarily accumulating in the upper layers and significant migration of cadmium and lead in the deeper layers. Pb isotopes and the Hydrus model trace the sources of Pb contamination and predict its distribution, indicating the significant contribution of e-waste recycling activities and minor impacts from other anthropogenic sources. Additionally, the model predicts a concentration of 60% of Pb contaminants in the surface soil within the next 30 years. These findings provide a foundation for evaluating and remediating abandoned e-waste recycling sites.

Summary: Oxygen dynamics play a key role in controlling nitrous oxide (N2O) production processes in arable soils. Bacterial denitrification is the primary source of N2O emissions during the hot-wet summer, while nitrification or fungal denitrification contribute to about 50.0% of total emissions during the cold-dry winter. The findings help improve process models and develop targeted mitigation measures for N2O emissions.

Summary: Anthropogenic activities significantly increase GHG emissions in inland waters, with land use being more influential than seasonality. Agriculture-dominated catchments and streams with wastewater inflows have much higher and more variable emissions of CO2, CH4, and N2O compared to forested streams. Nutrient, labile carbon, and dissolved GHG inputs from agricultural and settlement areas contribute to these hotspots and hot-moments of fluvial GHG emissions. The annual emissions from anthropogenic-influenced streams are up to 20 times higher than natural streams, primarily driven by CO2.

Summary: Tropical montane forests have high levels of soil organic carbon storage, but global warming may affect these stocks through enhanced soil respiration. In situ and ex situ warming studies were conducted along an elevation gradient in Uganda. The results showed that specific heterotrophic CO2 respiration decreased linearly with increasing elevation, and the temperature sensitivity increased. After 2 years of in situ warming, specific heterotrophic SOC respiration tended to be lower, while the delta C-13 values and SOC content tended to increase and decrease, respectively. In conclusion, climate warming may trigger enhanced losses of SOC from tropical montane forests due to temperature sensitivity and SOC content changes.
