Summary: The increasing quantities of organic residues pose a significant challenge to climate change mitigation, requiring sustainable utilization technologies. Processes such as biogas systems are promising for treating residues and improving agricultural productivity while reducing environmental impact. Research on the effectiveness of digestate on soil quality, crop productivity, and greenhouse gas emissions is still lacking, but promising results have been found in controlled climate conditions.

Summary: This study compared seasonal soil CO2, CH4, and N2O fluxes in a black mangrove forest in Veracruz, Mexico, subjected to different levels of environmental degradation. Results showed a combined effect of seasonality and degradation on CH4 fluxes, while CO2 fluxes were primarily influenced by water level, redox potential, and soil Cl- and SO4-2 concentration.

Summary: This study assessed the greenhouse gas emissions from rice fields amended with composted two-phase olive mill waste (C-TPOW) in Mediterranean conditions. The results showed that compost reduced CO2 emissions but increased CH4 and N2O emissions. However, there were no significant differences in global warming potential (GWP) and yield-scaled GWP between the compost and control treatments after three years.

Summary: In this study, a bibliometric review and global-scale analysis were conducted to explore the potential approaches for controlling greenhouse gas (GHG) emissions in constructed wetlands (CWs). The research on CWs has evolved through three stages over the past 15 years: GHG emission level assessment, mechanisms, and control. It was found that the type of CWs is closely related to GHG emissions, with different types emitting different GHGs. Optimizing CW operation can synergistically reduce GHG emissions while enhancing pollutant removal.

Summary: Changes in the energy market are causing a projected reduction in lignite excavation in the near future. The flooding of lignite mines left abandoned can potentially release greenhouse gases, which is a growing environmental concern. Research has shown that different types of lignite have varying greenhouse gas emissions, with lignite with shorter existence emitting the lowest amount of gases with global warming potential.

Summary: The Guadalete estuary in Spain was found to be a source of CO2, CH4, and N2O to the atmosphere, with CH4 showing the strongest relationship with DOM composition. Terrestrial and microbial humic-like substances with increasing aromaticity were linked to higher pCO2 levels, while N2O was related to the protein-like fraction and humic-like material from anthropogenic activities. This indicates a possible coupling between benthic fluxes of GHGs and DOM in this estuarine system, highlighting the importance of considering DOM composition in studying GHGs distribution in estuaries for better understanding of their roles in response to climate change.

Summary: This study investigated the formation of greenhouse gases during the ensiling process, focusing on the variations in CO2, N2O, and CH4 concentrations in forage. Grass and lucerne were ensiled at different dry matter concentrations in laboratory-scale barrels, showing that low DM concentration led to faster CO2 production, while lucerne forage and higher DM concentrations resulted in increased N2O concentrations. The study also found that butyric acid formation by clostridia contributed to CH4 formation, with lucerne silage exhibiting significantly higher concentrations from day 13 of ensiling. These findings highlight the impact of malfermentation on greenhouse gas emissions during ensiling.

Summary: This study explores the responses of greenhouse gas emissions to land use conversion or reversion. Results show that methane (CH4) and nitrous oxide (N2O) emissions respond positively to land use conversion, while carbon dioxide (CO2) emissions respond negatively to the changes from natural herb and secondary forest to plantation. The study also highlights the long-term impact of soil carbon on CO2 emissions after land use conversion.

Summary: The potential effects of tidal and diel cycles on carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) concentrations and fluxes in tropical estuaries are poorly understood. This study conducted sampling for nine consecutive days in the Mahanadi estuary of India and found that tidal forcing affected CO2 and CH4 concentrations, with higher concentrations during low tide. CO2 concentrations increased with decrease in tidal height, possibly due to higher freshwater contribution. N2O showed no significant variability with tidal cycle or water level fluctuation. The study area was a source of greenhouse gases to the atmosphere, except for the offshore region.

Summary: The use of manure in corn production systems can help reduce GHG emissions by avoiding the production and application of mineral fertilizers. Corn produced under manure has a lower intensity of GHG emissions, about 15% less than those under sole mineral fertilizers, which can contribute significantly to climate change mitigation. Further research is needed to assess the alternative fate of manure and to expand the system boundary to assess agriculture and livestock sectors holistically.

Summary: Precision fertilization, including variable-rate fertilization, is a promising approach to reduce the environmental impacts of nitrogen fertilization. This study evaluated the short-term response of greenhouse gas emissions following variable-rate fertilization on barley. The results showed that variable-rate fertilization can maintain high yields with a significant reduction in nitrogen application and improved nitrogen use efficiency. However, the sensor-based nitrogen application did not result in significantly different greenhouse gas emissions compared to conventional fertilization, suggesting the need for further research.

Summary: In oyster habitats, the sediments show peak carbon dioxide production in spring and summer, as well as consistent methane release into the water column, while nitrous oxide is generally absorbed with occasional release in spring. The overall impact of oysters on sediment greenhouse gas cycling in temperate regions is considered negligible.

Summary: Inland waters, especially small ponds, have a significant but poorly understood role in global greenhouse gas emissions. This study conducted high-resolution temporal sampling and found that temperate constructed ponds are a net source of greenhouse gases, with methane emissions being highly variable within seasons. The study suggests that building ponds to favor mixed conditions can help minimize the global greenhouse gas footprint of future pond construction.

Summary: The study found that after three years of application in the agricultural system, digestate fertilization increased the nitrogen, phosphorus, and potassium content in the soil, with yields higher than synthetic nitrogen fertilizer. There was a strong correlation between nitrogen use efficiency and yield in the digestate treatments, showing potential for short to mid-term use compared to synthetic nitrogen fertilizer.

Summary: This study evaluates the environmental impact of sustainable pig farms and proposes methods for managing nutrient and co-product flows. The findings suggest that utilizing organic waste for biogas production and replacing mineral fertilizers can mitigate gaseous emissions and produce renewable energy and high-quality fertilizers. However, the current system still needs improvement to fully utilize these waste materials.

Summary: Efficiency in achieving a circular economy in agriculture, particularly in sustainable nitrogen management, is a current focus. This study investigates the use of pig manure digestate combined with biochar and ash as a nitrogen source in comparison to mineral fertilization. Results show that these organic amendments have positive effects on potassium, phosphorus, biomass yield, and nitrogen use efficiency. They also have lower carbon dioxide emissions compared to mineral fertilizers. However, they influence nitrous oxide emissions differently. The combination of pig manure digestate with biochar and ash has a negative impact on enzymatic activity but increases soil microbial biomass carbon. Overall, these amendments have the potential to optimize nitrogen and carbon efficiency for sustainable soil management.
