Summary: Intermittent irrigation systems, such as mid-season drainage (MSD), have been found to significantly reduce methane (CH4) emissions in rice cultivation. A recent study in Spain showed that MSD not only reduced CH4 emissions during the growing season by around 80%, but also continued to lower emissions by approximately 60% during the following winter flooded fallow season.

Summary: Denitrification bioreactors are effective in reducing nitrate from subsurface drainage, but they may also produce other pollutants and greenhouse gases. A woodchip bioreactor system showed near complete removal of nitrate in both chambers during the first two years of monitoring. In the third year, significant nitrate reduction was observed in chamber A, alongside production of dissolved methane and nitrous oxide in both chambers. The overall impact on the landscape-scale was small, but pollution swapping can be reduced in woodchip bioreactors under low-flow conditions.

Summary: One of the main causes of climate change is agriculture, which emits greenhouse gases (GHGs) through plant production. However, this study found that the application of beneficial plant growth-promoting rhizobacteria (PGPRs) in strawberry cultivation can help limit GHG emissions. By experimenting with different bacterial strains and moisture conditions, five strains were identified as having the potential to reduce GHG emissions. Therefore, the application of these bacterial strains can be an effective strategy for mitigating climate change.

Summary: Organic rice farming is considered safe and environmentally friendly, but the use of fresh organic matter as fertilizer can lead to increased methane emissions. This study evaluated methane and net greenhouse gas emissions in long-term organic rice paddy fields, and looked at the effects of green manure and mid-season drainage on rice grain yield. Early incorporation of green manure did not increase CO2 or decrease CH4 emissions, while early mid-season drainage reduced CH4 emissions and contributed to soil carbon sequestration and greenhouse gas reduction.

Summary: A study was conducted to determine the optimal timing for mid-season drainage (MSD) in rice cultivation based on canopy light interception (CLI) indicators. The results showed that the CLI values varied significantly depending on the rice variety, planting method, and growing season. Further optimization of the current parameters is needed to improve their robustness.

Summary: Maintaining current levels of rice production in the face of future climate changes presents a significant challenge. High-resolution climate projections suggest advancements in secure sowing dates and delays in secure maturation dates, along with a potential increase in growing season length and growing accumulated temperature. Southern regions such as Guangdong, Guangxi, and Hainan are projected to experience earlier sowing, later maturation, longer growing seasons, and higher temperatures. This information can help farmers make informed decisions on cultivation adjustments and variety selections.

Summary: The study indicates that shallow urban polluted reservoirs in tropical regions can be hotspot for CO2 and CH4 emissions, with nutrient-rich conditions leading to increased greenhouse gas emission. High concentrations of nutrients in the water column support the production of autotrophic biomass that contribute to CH4 emission. The findings highlight the importance of water quality improvement and eutrophication mitigation in highly urbanized reservoirs in tropical regions.

Summary: This study evaluated the effects of mid-season drainage on iron toxicity, rice yield, and water productivity, and identified the factors that favor rice yield in fields with mid-season drainage compared to continuous flooding. The results showed that mid-season drainage significantly reduced iron toxicity and increased rice yield and water productivity. It is recommended to use mid-season drainage and appropriate fertilizer management in fields with high soil organic carbon and iron toxicity to improve rice yield and water productivity.

Summary: After changes in tillage, it is important to assess the effects on soil organic carbon dynamics. This study found that the changes in irrigation and tillage in rice cultivation did not significantly affect the input and output of organic carbon in the soil. However, compared to agroforestry, the irrigation and tillage management systems in rice cultivation showed a negative difference between carbon inputs and outputs due to increased crop root respiration and microbial activity. Agroforestry was proven to be a carbon sink.

Summary: Integrated rice-crayfish farming system (RCS) is popular in China, but the impact of trench on greenhouse gas (GHG) emissions has been ignored. This study compared GHG emissions between rice monoculture (RM) and RCS, finding that RCS had lower CH4 emissions due to lower mcrA abundance and higher pmoA abundance. However, the trench resulted in higher CH4 emissions and lower N2O emissions compared to the RCS field. Overall, RCS does not mitigate global warming potential (GWP) compared to RM, unless the area ratio of the trench to the system is controlled below 13.9%.

Summary: Soil carbon cycling and ecosystem functioning depend on how microbial communities regulate their metabolism and adapt to changing environmental conditions. Investing in extracellular enzyme production is an important strategy to acquire resources, but the trade-offs between enzyme production and growth are not well understood. This study shows that regulating the enzyme production rate per unit biomass can maximize biomass specific growth rate. The optimal enzyme production rate decreases hyperbolically with soil organic carbon content. Integrating optimal enzyme production into soil microbial carbon models can significantly change soil carbon projections under global warming, highlighting the need to improve parameterization of microbial processes.

Summary: Enhanced weathering (EW) is a sustainable negative emissions technology that can sequester CO2 through accelerated dissolution of silicate rocks. However, fundamental advances such as identifying suitable environmental conditions, improving estimates of field dissolution rates and efficacy of CO2 removal, and finding alternative sources need to be addressed before widespread adoption of EW.

Summary: Climate change and unsustainable land management practices have led to extensive soil degradation, including changes in soil structure, loss of soil organic carbon, and reduced water and nutrient holding capacities. To improve predictions of soil hydrological and biogeochemical cycles, models need to incorporate dynamics of soil structure and macroporosity, whether in natural or agricultural ecosystems.

Summary: Climate has a critical role in influencing soil carbon turnover and storage by regulating water availability and temperature. This study shows that soil carbon turnover time and its variability are strongly related to ecosystem aridity. Wetter regions have faster but more variable soil carbon turnover, indicating complex carbon cycling processes. These findings are important for improving soil carbon models and predicting soil carbon dynamics under climate change.
