Summary: This study estimated the magnitude of NBP in 31 Chinese provinces (except Hong Kong, Macau, and Taiwan) from 2000 to 2018, and clarified its temporal and spatial evolution. The results show that NBP in China is mainly distributed in southwest and south China, with a total amount of about 0.21 Pg C/yr(-1).

Summary: Uncertainties in tree carbon allocation to growth limit projections of forest carbon sequestration and response to climate change. Our study reveals widespread decoupling between carbon assimilation and tree growth, driven by varying climatic sensitivities and tree species. Sink control over tree growth becomes more prominent with canopy closure, aridity, and decreasing temperatures.

Summary: Carbon sink in terrestrial ecosystems is crucial for achieving carbon neutrality and sustainable development goals. The study reveals that China's ecosystems acted as a carbon source in 2017, but the eastern region served as a carbon sink. The potential for the transformation from carbon sink to carbon source is expected to increase in central, eastern, and western China, with precipitation playing a significant role in carbon balance. Additionally, the central subtropical broad-leaved evergreen zone is identified as a key region for future carbon sequestration.

Summary: Land use changes and climate change have significantly impacted the terrestrial ecosystem carbon balance in China. Research found that from 2000 to 2015, there were noticeable regional variations in carbon balance, with North and Northwest China acting as carbon sources while other regions were carbon sinks. Net Ecosystem Productivity (NEP) showed an increasing trend throughout the regions, except for the Mid-South region.

Summary: The timing and magnitude of grassland responses to drought within a growing season remain unresolved. This study used remote sensing data and weather data to investigate the impacts of drought on grasslands in the western US Great Plains biome. The results showed that grassland carbon uptake was reduced during drought, with larger reductions in the warmer and more southern regions. Increased summer vapor pressure deficit was strongly linked to reductions in vegetation greenness during drought.

Summary: This study investigated the impact of climate change and rising CO2 on China's land use/cover change and its effect on the carbon budget. It was found that afforestation and ecological restoration can increase carbon sinks, while agricultural reclamation contributes to carbon loss. The response to climate change varies across different geographic regions, highlighting the need for tailored land management strategies.

Summary: This study investigated the input and output fluxes of dissolved organic carbon (DOC) and their impacts in a subtropical plantation headwater catchment. The results showed that dry deposition of plant-derived DOC was higher than wet deposition from precipitation, and soil-buffered DOC fluxes were significant in the catchment. The findings highlight the importance of considering plant-derived DOC deposition in carbon sink estimations.

Summary: This study investigated the impact of land use change on carbon balance, showing an overall increasing trend in carbon emissions (CE) from 2000 to 2015, especially in the industry sector. The findings suggest a positive correlation between land use intensity and CE, highlighting the importance of strengthening land management and optimizing urban planning for promoting low-carbon development.

Summary: This study investigates the ability of macroalgae to sequester inorganic carbon in the ocean, using the largest green tide caused by Ulva prolifera as a case study. The research shows that massive macroalgae release organic carbon, which is transformed into dissolved inorganic carbon (DIC) by microorganisms. Field investigations reveal that DIC and total alkalinity (TAlk) increase significantly in areas covered by dense U. prolifera, and offshore mapping cruises confirm higher levels of DIC and TAlk during the bloom stage. Laboratory cultivation of U. prolifera further demonstrates the enhancement effect of DIC and TAlk in seawater. This research highlights the importance of macroalgae in regulating the carbon pool in the ocean.

Summary: The study estimated the net primary productivity (NPP) over a two-year period in a 25-year-old Scots pine stand from 2019 to 2020, and found a higher increase in biomass in 2020 compared to 2019, leading to higher carbon use efficiency (CUE) in 2020. However, the CUE values were lower than those reported in the literature for comparable temperate forest stands, indicating a need for further analysis of physiological responses to extreme conditions.

Summary: This study simulated forest carbon fluxes in two major plant functional types in the northwest Himalayan foothills of India using remote sensing data and Biome-BGC model. The study found that integrating remote sensing data into the calibrated process-based model increased the accuracy of model-simulated forest carbon fluxes.

Summary: In a replicated experimental study in loblolly pine plantations, it was found that soil heterotrophic CO2 efflux responds differently than net primary productivity to fertilization and drought treatments, leading to divergent responses of net primary productivity and net ecosystem production. The responses of net primary productivity and soil heterotrophic CO2 efflux to fertilization combined to increase net ecosystem production significantly under drought treatment.

Summary: An empirical model of respiration and net ecosystem productivity was developed and tested in a subtropical coniferous plantation in China, with reasonable agreement between simulation and observation results. The PAR energy method was applied to capture and describe the main energy interactions in CO2 processes, leading to the development of useful empirical models for gross primary production, respiration and net ecosystem productivity.

Summary: Carbon emissions in agriculture are significant in climate change. Modeling studies enable investigation of climate change impact on crops, accounting for soil organic carbon feedbacks and CO2 concentrations. Crop models need to properly consider CO2 exchanges in crop rotations. The model accurately simulates CO2 fluxes in a long-term and diversified crop rotation.

Summary: The application of nitrification and urease inhibitors with urea can reduce nitrogen losses, especially in rice. Urea rate reduction can decrease N2O and NH3 emissions, but may lower yield and N use efficiency. Co-application of urea with inhibitors can maintain good yield and N use efficiency, while also reducing N2O and NH3 emissions.

Summary: Study on acidification of five different organic slurries using different application techniques and commercial acidifications system showed that in spring barley, slurry incorporation and closed slot injection significantly reduced NH3 emissions, with reductions of 89% and 96% respectively, while incorporation alone decreased emissions by 60%. In winter wheat, acidification reduced NH3 emissions by 61-67% in cattle slurry, 45-57% in anaerobic digestate, and 58% in liquid phase of anaerobic digestate. Acidification consistently reduced NH3 emissions of most slurry types, with limited effect in pig slurry.

Summary: Ammonia emissions from agriculture have significantly increased, and agriculture is now the main source of ammonia in the atmosphere. Existing methods for calculating national emissions do not consider regional variations. Researchers have proposed a simple model that takes into account various factors to accurately calculate emissions, without requiring extensive input data.

Summary: Urea granule dissolution in soil and soil urease activity are crucial for accurately predicting nitrogen dynamics after urea application. This study investigated the dissolution of urea granules and the activity of urease in soil under different temperatures. The results showed that soil moisture was the dominant factor at low moisture contents, while temperature controlled the dissolution process at higher moisture levels.

Summary: This study investigated the effects of different forms of nitrogen fertilizers (nitrate vs. ammoniacal nitrogen) and urease inhibitors on N2O emission and crop yield. The results showed no significant difference in N2O emissions between calcium ammonium nitrate (CAN) and urea, but the addition of the nitrification inhibitor, DCD/TZ, significantly reduced N2O emissions. The addition of urease inhibitors did not further reduce N2O emissions, but it improved crop yield and nitrogen utilization efficiency.
