Summary: The ongoing global warming is causing paddy soil to experience higher levels of carbon and nitrogen loss. This study investigates the effects of temperature on soil organic matter (SOM) decomposition and microbial characteristics in different soil layers. The results show that warming promotes the decomposition of recalcitrant SOM and enhances the relative abundance of oligotrophic bacteria. Understanding these mechanisms is crucial for monitoring carbon dynamics in deep soil affected by global climate changes.

Summary: This study explores the spatial variability and regulatory mechanisms of soil organic matter (SOM) and temperature sensitivity (Q (10)) along elevational gradients in different mountains globally. The study finds that SOM content changes significantly with increasing altitude, with differences observed across different climate zones. Climate factors and soil properties account for a large portion of the spatial variation in SOM, while Q (10) does not show a clear global pattern but is influenced by changes in soil substrate quality along altitudinal gradients.

Summary: This study reveals the significant impact of incubation temperature range (ITR) scenarios on the temperature sensitivity (Q(10)) of soil organic matter (SOM) decomposition, which is often overlooked. The results suggest that the growing season average temperature range (GSA) scenario performs better than other ITR scenarios and should be considered as the optimum ITR scenario. Additionally, accounting for the variation of main influence factors of Q(10) across different ecosystems is crucial for accurate prediction of the feedback between soil carbon cycle and climate change.

Summary: Soil biogeochemical processes exhibit depth-dependent responses to climate change. This study presents an innovative and cost-effective approach of field incubation of intact soil cores to explore this depth dependence. The results indicate that soil respiration responds significantly to climate shifts induced by translocation experiments, but this response is independent of soil depth.

Summary: The role of soil in Earth's carbon budget is uncertain. A new model shows that soil temperature and moisture are linked to global soil respiration. Heterotrophic respiration has been increasing by 2% per decade since the 1980s, and it is projected to increase by 40% by the end of the century. Soil carbon efflux is the largest terrestrial carbon source to the atmosphere, but it remains one of the most uncertain fluxes in the global carbon budget.

Summary: This study compared the difference in soil organic carbon (SOC) sequestration and stability between farmland and shelterbelt forests by collecting soil samples. The results showed that shelterbelt forests had significantly higher SOC concentration than farmland, while there was no significant difference in SOC respirational decomposition rate between the two. The respiration patterns of both shelterbelt forests and farmland changed with increasing soil moisture. The stability of SOC was influenced by geographic-climate factors and soil properties. The findings suggest that these SOC changes can improve the carbon sequestration function of shelterbelt forests.

Summary: The addition of different oxides in paddy soil affected the mineralization of soil organic matter differently, with ferrihydrite significantly decreasing dissolved organic matter content but increasing microbial biomass carbon content. Oxides like birnessite and ferrihydrite altered soil pH, available nitrogen content, and redox potential, while also impacting soil bacterial abundance and composition. The potential mechanisms of oxides in reducing soil organic matter mineralization included stimulating microbial assimilation of organic carbon, modulating soil properties, and altering bacterial community composition.

Summary: Dissolved oxygen (DO) impairment is a common issue in coastal waters, and rising temperatures exacerbate low DO levels through enhanced organic matter (OM) degradation. This study investigates the temperature sensitivity of OM degradation and found that wetland sites have a higher sensitivity compared to river and stormwater pond sites. Predicted increases in DO decay rates for wetlands are also higher than those for rivers and stormwater ponds due to climate change. These findings highlight the importance of considering OM heterogeneity and temperature sensitivity in predicting the impact of climate change on oxygen impairment in aquatic ecosystems.

Summary: Inland waters (rivers, reservoirs, lakes, ponds, streams) and estuaries are significant emitters of methane (CH4) and nitrous oxide (N2O) to the atmosphere. However, global estimates of these emissions have been limited by the lack of comprehensive data. By synthesizing existing measurements, this study estimates global CH4 and N2O emissions from inland waters and estuaries. The results show that these aquatic systems release large amounts of CH4 and N2O, with rivers and lakes being the major contributors. Ebullition is identified as the dominant flux component of CH4. Dissolved oxygen in water plays a crucial role in influencing both CH4 and N2O emissions.

Summary: Misuse and overuse of antibiotics have led to the rise of antimicrobial resistance. In agricultural soils, antibiotics and antibiotic resistance genes (ARGs) are mostly found due to the application of livestock and organic wastes. Cattle manure, chicken manure, swine manure, and sewage sludge are the primary sources of antibiotics and ARGs in agricultural soils. Sulfonamides, tetracyclines, fluoroquinolones, and corresponding ARGs are the major types of pollution. Land-use type, soil, and climatic factors affect the concentrations of antibiotics and abundances of ARGs. Mobile genetic elements (MGEs), especially the sul1 gene, play a vital role in promoting the dissemination of ARGs. Better management of antibiotic and ARG contamination in agricultural soils is important for human health.

Summary: Based on research findings, the sensitivity of N2O emissions in tea plantations is influenced by soil acidity and climate factors. Tea plantations significantly contribute to N2O emissions in the agricultural sector globally, and the intensity of greenhouse gas emissions per unit yield is higher compared to other upland cereals. Implementing climate-smart practices in Chinese tea plantations can reduce emissions equivalent to one-third of the global total, highlighting the importance of targeted measures for achieving global temperature control targets.

Summary: Applying biochar and 3,4-dimethylpyrazole phosphate (DMPP) can effectively mitigate soil nitrous oxide (N2O) emissions, but their efficiency can be influenced by soil properties and microorganisms. This study investigated the effects of biochar and/or DMPP on N2O emissions from different agricultural soils and found that biochar reduced N2O emissions from vegetable and tea soils by inhibiting ammonia oxidation, while promoting N2O emissions from peach orchard soils. DMPP application mitigated N2O emissions, but its efficiency was weakened when co-applied with biochar in tea and peach soils.

Summary: Existing studies suggest that biochar application can reduce soil nitrous oxide (N2O) emissions, but the effects and mechanisms of the legacy of biochar on N2O emissions after many years of application are still unclear. This study found that biochar can alleviate soil N2O emissions, possibly through the reduced effectiveness of the soil substrate, decrease in nitrification and denitrification activities, and promotion of N2O reduction. However, the abatement capacity of biochar may weaken over time after application, which needs further investigation.

Summary: Applying biochar amendment and manure in tea plantation ecosystems can help reduce soil acidification and degradation. The impact of biochar amendment on soil respiration is not significant, but it can indirectly enhance carbon sequestration. On the other hand, replacing mineral fertilizer with manure significantly stimulates soil respiration and CO2 emissions in a tea plantation.
