Summary: Biochar addition increased soil CO2 emissions but decreased N2O emissions, while N addition increased both CO2 and N2O emissions. The combination of biochar and N addition showed significant positive effects on CO2 and N2O emissions, with no significant changes in CH4 fluxes. Antagonistic interaction was observed between biochar and N addition in soil GHG fluxes and their global warming potential.

Summary: The purpose of this study was to investigate the variation of stem and soil greenhouse gas fluxes along a topographic gradient in a tropical forest. The results showed that both wetland and slope soils and tree stems were sources of CO2, while fluxes of CH4 and N2O were more variable and influenced by temperature and soil water content.

Summary: Liming, a management practice used worldwide to reduce the negative effects of acidification in soils, has been found to have a significant impact on greenhouse gas emissions. This global meta-analysis study shows that liming can reduce nitrous oxide (N2O) emissions by increasing the abundance of N2O reductase genes and decreasing the fungi:bacteria ratio in soil. It also suggests that liming can reduce methane (CH4) emissions and the abundance of methanogens, but has no effect on CH4 uptake and methanotrophs. Additionally, liming increases soil carbon dioxide (CO2) emissions due to higher respiration. The study highlights the importance of considering soil microbial communities in understanding and mitigating greenhouse gas emissions in response to liming.

Summary: Both nitrogen deposition and soil freeze-thaw cycles have significant effects on greenhouse gas emissions in temperate forest ecosystems, with nitrogen addition leading to increased N2O and CO2 emissions and inhibition of CH4 uptake. Soil respiration rate is significantly increased with medium sodium nitrate addition, and high levels of nitrogen addition inhibit CH4 uptake. Considerations of dissolved organic carbon, microbial biomass carbon and nitrogen, and inorganic nitrogen in soil are important for predicting future feedback effects of greenhouse gas emissions on climate change.

Summary: The study shows that the application of nitrification inhibitors and biochar in rice paddies can significantly increase yield and reduce global warming potential. Controlled-release nitrogen fertilisers have no effect on global warming potential, but can increase rice yield. No-tillage and non-continuous flooding can reduce global warming potential, but have different impacts on rice yield.

Summary: Climate warming increases soil greenhouse gas (GHG) emissions from croplands, with significant increases in carbon dioxide (CO2) and nitrous oxide (N2O) fluxes, as well as changes in methane (CH4) uptake and release. The responses of GHG fluxes to warming are influenced by initial substrates, wetness, and nitrogen fertilizer levels. This study highlights the importance of adjusting agricultural practices to mitigate climate change.

Summary: Despite their small size, fluvial ecosystems play a significant role in carbon processing and methane emissions. However, progress in understanding and estimating methane concentrations and fluxes in streams and rivers has been slow due to variability and limited data availability. In order to address these challenges, the Global River Methane Database (GriMeDB) provides a comprehensive resource of methane concentrations and fluxes, along with physical and chemical data, to examine environmental drivers and estimate fluvial contributions to methane emissions.

Summary: Biochar application has different effects on crop yield, soil organic carbon, and global warming potential when applied alone or combined with chemical fertilizers. The carbon to nitrogen ratio and soil pH are the key factors influencing the impact of biochar application on crop yield, SOC, and GWP. The study suggests that biochar properties and soil pH are crucial in determining the effectiveness of biochar application in improving crop yield, increasing SOC, and reducing GWP.

Summary: Soil salinization affects soil ecology and greenhouse gas emissions. Chitooligosaccharides and Arbuscular mycorrhizal fungi can reduce GHG fluxes in salinized soil by altering rhizosphere microecology. Certain bacterial species are highly correlated with GHG emissions, and foliar spraying of chitooligosaccharides enhances soybean tolerance to salt stress. The co-application of chitooligosaccharides and Arbuscular mycorrhiza fungi has a greater effect than their individual application.

Summary: Geographic information on soil organic carbon (SOC) is crucial for climate change research and understanding the global carbon cycle. This study focused on predicting SOC concentration in forested areas of Japan, using digital soil mapping (DSM) with a 10 m grid resolution. The random forest model (RF) was found to be the most appropriate for the area in comparison to ordinary kriging (OK) and regression kriging (RK), with RFenv+vol considered the best model due to its higher accuracy in predicting SOC stock (OCS).

Summary: This study analyzed the ecological traits of Cryptomeria japonica and Chamaecyparis obtusa, two major timber species in East Asia, to understand their differences in water, nutrient, and drought tolerance. Cryptomeria japonica showed higher photosynthetic rate, stomatal conductance, foliar nutrient content, and soil-to-foliage hydraulic conductance compared to Chamaecyparis obtusa, while Chamaecyparis obtusa exhibited better drought tolerance with lower turgor loss point and xylem pressure. The study highlighted the importance of using plant trait databases to verify empirical knowledge in plantation management and to assess the impact of climate change on forest ecosystems.

Summary: The study analyzed Cs-137 radioactivity data in edible forest products from the Fukushima Daiichi Nuclear Power Plant accident area, revealing varying concentration characteristics among different species. It was found that mycorrhizal mushrooms had higher Cs-137 concentrations, while wild edible plants had lower concentrations. By using a Bayesian model and detailed geographical information, accurate assessment of radiation exposure from contaminated wild mushrooms and plants was improved.

Summary: Soil respiration is an important process in the global carbon cycle and its spatial variability was studied on volcanic ash soil. The study found that organic carbon content in soil is not a key factor in controlling soil respiration rate, while the low-density fraction (LF-C) plays a significant role. After logging, soil respiration rate decreased significantly and LF-C stock was much lower compared to the standing-tree plot.

Summary: This study investigated the interannual changes in the vertical distribution of 137Cs in forest ecosystems contaminated by the Fukushima Dai-ichi Nuclear Power Plant accident. The results showed that the 137Cs inventories in the organic horizon were decreasing exponentially, while most of the 137Cs in the mineral soil horizon was found in the surface layer. Although there were exponentially increasing trends in a lower layer of the mineral soil horizon, there was no clear increasing or decreasing trend in the deeper mineral soil layers. The downward migration of 137Cs was not significant in terms of the overall 137Cs distribution in the mineral soil horizon over 10 years.

Summary: The global forest carbon stock is mainly found in soil organic matter and understanding the effects of forest management practices on soil carbon stocks and greenhouse gas emissions is crucial for effective climate change mitigation strategies. This study synthesized literature on forest management practices that increase soil carbon stocks and reduce greenhouse gas emissions. Soil processes, such as nitrogen fertilization and peatland hydrology management, play a significant role in soil greenhouse gas balance.

Summary: The Fukushima nuclear power plant catastrophe led to the contamination of forest ecosystems with 137Cs in 2011. This study simulated the spatiotemporal distribution of 137Cs concentrations in the litter layer of the contaminated forests over two decades. The deposition of 137Cs was found to be the most significant factor in litter contamination, but vegetation type and mean annual temperature also played important roles. The long-term management of contaminated watersheds should consider not only 137Cs deposition but also elevation and vegetation distribution to identify areas of long-term 137Cs contamination.
