Aims Biogenic volatile organic compound (BVOC) emissions from leaf litter play an important role in forest carbon (C) cycles. This study investigated the combined effects of nitrogen (N) addition and leaf litter species on BVOC emissions and the relative contribution of C emissions in the form of BVOCs to CO2 emissions. Methods An incubation experiment was conducted using two levels of N addition and two leaf litter species (Schima superba and Cunninghamia lanceolata). We measured BVOC and CO2 emissions and litter chemical properties during litter decomposition. Results Total BVOC-C emitted from two leaf litter species accounted for 0.19%-0.47% of CO2-C emissions. N addition decreased the total BVOC emissions, but increased CO2 emissions from the decomposition of both litter species. N addition increased total N and soluble sugar contents of leaf litter but reduced the starch content and C/N ratio. Following N addition, the fluxes of most BVOC types were positively correlated with starch and nonstructural carbohydrate contents of S. superba leaf litter and with the C/N ratio of C. lanceolata leaf litter. In addition, the total BVOC and CO2 emissions from S. superba leaf litter were higher than those from C. lanceolata. Corresponding, S. superba leaf litter had higher N and soluble sugar contents but lower C/N ratio and starch content than C. lanceolata leaf litter. Conclusion N addition inhibited BVOC emissions and promoted CO2 emissions during leaf litter decomposition. Leaf litter with a high labile substrate content is likely to release more BVOCs during the early-stage of litter decomposition.

Co-application of Mg fertilizer and biochar alleviated soil acidification and improved soil quality.Co-application of Mg fertilizer and biochar improved the microbial community and enhanced potential beneficial microbes.Co-application of Mg fertilizer and biochar significantly improved the tea quality and yield.Soil acidification and magnesium (Mg) deficiency are common problems in tea plantations. The application of biochar and Mg fertilizer has been believed to alleviate soil acidification and improve soil Mg nutrient. However, it is unclear how co-application of biochar and Mg fertilizer improve soil pH, nutrients, and microbial communities, and then enhance tea quality and yield. A 2-year field experiment was conducted to determine the effects of co-application of biochar and Mg on soil properties, microbial community, tea quality and yield in a strongly acidic tea plantation. The results showed that Mg fertilizer with biochar was conducive to alleviate soil acidification, with pH increased from 4.25 to 4.72. Soil total carbon, total nitrogen, available potassium and exchangeable magnesium contents and bacterial community diversity significantly enhanced. In addition, the relative abundance of some potential beneficial bacteria, including Devosia, Bacillariophyta, Gaiella increased. The contents of amino acid and caffeine in tea were significantly increased, and the yield was increased by 39.40% with biochar and Mg fertilizer co-application. In general, biochar and Mg fertilizer co-application is beneficial to soil acidification and the promotion of tea quality and yield, which may be a visionary fertilizer management strategy for strongly acidic tea plantations.

Abstract ：
Carbonyl sulfide (OCS) and carbon disulfide (CS2) are important sulfur carrier gases in the atmosphere. Higher plants have been identified as both their consumers and emitters, but relatively few studies focus on plants in high-latitude ecosystems. In this study, dominant plants (moss, lichen, and hair grass) and soils were collected across tundra ecotopes in maritime Antarctica and incubated under controlled conditions to explore the uptake and emission of OCS and CS2. Tundra vegetation (e.g., Sanionia georgicouncinata, Sanionia uncinata, Usnea antarctica) consistently consumed OCS (-2.66 to -11.36 pmol m(-2) s(-1)) and CS2 (-0.08 to -0.48 pmol m(-2) s(-1)) with a significant positive correlation between their uptake rates (r = 0.99, p < 0.001), likely driven by the activities of RuBisCO, an enzyme involved in photosynthesis. In comparison, tundra soils fluctuated between sources and sinks of OCS (-1.65 to 4.29 pmol m(-2) s(-1)) but showed consistent CS2 emissions (4.70 to 7.65 pmol m(-2) s(-1)). Particularly, penguin colony soils were uniform sources of OCS and CS2. Plants dominated the overall uptake of OCS and CS2 by Antarctic tundra (>= 66%), and these biogenic sinks are expected to be conserved under climate warming, accompanying the enhancement in OCS uptake with light intensity. This study improved our understanding of sulfur biogeochemical interactions and their environmental implications in Antarctic tundra.

Abstract ：
Soil water availability and nitrogen (N) deposition critically influence biogenic volatile organic compound (BVOC) emissions, thereby affecting atmospheric chemistry. However, their differential short- and long-term effects remain unclear. Here, Ormosia pinnata and Pinus massoniana seedlings were exposed to three water regimes (moderate drought, MD; normal irrigation, NI; near-saturated irrigation, NSI) and two nitrogen (N0; 0 kg N ha-1 yr-1; N80; 80 kg N ha-1 yr-1) treatments for 20 months. Branch-level BVOC emissions and leaf physiological and biochemical traits were examined after 8 months (short term) and 16 months (long term). In the short term, P. massoniana predominantly emitted alpha-pinene, beta-pinene, and gamma-terpinene, whereas O. pinnata emitted isoprene (ISO). After prolonged exposure, ISO became the dominant in both species. Short-term MD and NSI conditions stimulated ISO emissions in O. pinnata, with N80 addition further amplifying this effect. In contrast, long-term treatments tended to suppress ISO emissions in O. pinnata, particularly under N80. Short-term water treatments had no significant effect on monoterpene (MT) emissions in P. massoniana. Under long-term water treatments, N80 suppressed ISO emissions; nevertheless, ISO emission rates (ISOrate) progressively increased with increasing soil water availability. Although leaf intercellular CO2 concentration (Ci), stomatal conductance (gs), and photosynthesis-related enzymes exhibited partial correlations with BVOC emissions, an overall decoupling between leaf traits and emission patterns was evident. Our findings demonstrate the significant changes in both BVOC composition and emission magnitudes under the joint effects of water availability and nitrogen deposition, providing important implications for improving regional air quality modeling and BVOC emission predictions.

Abstract ：
Biochar amendments are effective in stabilizing soil aggregates and improving soil organic carbon content. Although the influence of soil aggregates, organic carbon fractions and pH on soil organic carbon (SOC) stability is acknowledged, the effects of biochar on highly acidic soil and their relation with soil aggregates and SOC stability remain understudied. Our study highlights the potential benefits of biochar application on soil carbon stabilization compared to soils without biochar. The study aimed to investigate the impact of biochar on changes of aggregate distribution and SOC stability in a highly acidic tea plantation soils over an eight-year period. Soil samples were collected from plots with varying biochar application amounts (0, 2.5 t ha−1, 5 t ha−1, 10 t ha−1, 20 t ha−1 and 40 t ha−1). The content of SOC, iron-bound organic carbon (OC-Fe), particulate organic carbon (POC), and mineral-associated organic carbon (MAOC) was analyzed. Additionally, the functional group composition of SOC was characterized using diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS). The results indicated that biochar application led to significant enhancements in soil pH, compared with CK, the value of soil pH increased from 3.92 to 4.28, the content of macro-aggregate (particle size>0.25 mm) and soil aggregates mean weight diameter (MWD) significantly increased with higher biochar application amounts. Compared with CK, the content of SOC increased from 6.68%(BC2.5) to 187.02%(BC40). DOC and OC-Fe content exhibited downward trend, decreased from 2.43%(BC5) to 6.97%(BC10) and 4.18%(BC2.5) to 19.91%(BC10). POC and MAOC content increased from 8.31% to 66.78% and 13.07% to 236.47% respectively, compared with CK. Furthermore, aromatic-C levels increased, with increased biochar application amounts. The integration of biochar not only bolstered soil aggregate stability but also amplified the presence of aromatic-C, thereby enhancing the resilience of organic carbon in highly acidic tea garden soil (BC40＞BC20＞BC5＞BC2.5＞BC10＞CK), with increases ranging from 6% to 47%. The principal component analysis identified soil pH, SOC, POC, MAOC, TN, R＞0.25 and MWD as key factors of soil organic carbon stability. These findings provide crucial insights into the mechanism underlying biochar’s efficiency in fortifying organic carbon stability, particularly in the context of strongly acidic soil. © 2024, The Authors.

Abstract ：
Isoprenoids (including isoprene (ISO) and monoterpenes (MTs)) are the majority of biogenic volatile organic compounds (BVOCs) which are important carbon -containing secondary metabolites biosynthesized by organisms, especially plant in terrestrial ecosystem. Results of the warming effects on isoprenoid emissions vary within species and warming facilities, and thus conclusions remain controversial. In this study, two typical subtropical tree species seedlings of Schima superba and Cunninghamia lanceolata were cultivated under three conditions, namely no warming (CK) and two warming facilities (with infrared radiators (IR) and heating wires (HW)) in open top chamber (OTC), and the isoprenoid emissions were measured with preconcentor-GC - MS system after warming for one, two and four months. The results showed that the isoprenoid emissions from S. superba and C. lanceolata exhibited uniformity in response to two warming facilities. IR and HW both stimulated isoprenoid emissions in two plants after one month of treatment, with increased ratios of 16.3 % and 72.5 % for S. superba , and 2.47 and 5.96 times for C. lanceolata . However, the emissions were suppressed after four months, with more pronounced effect for HW. The variation in isoprenoid emissions was primarily associated with the levels of Pn, Tr, monoterpene synthase (MTPS) activity. C. lanceolata predominantly released MTs (mainly alpha-pinene, alpha-terpene, gamma -terpene, and limonene), with 39.7 % to 99.6 % of the total isoprenoid but ISO was only a very minor constituent. For S. superba , MTs constituted 24.7 % to 96.1 % of total isoprenoid. It is noteworthy that HW generated a greater disturbance to physiology activity in plants. Our study provided more comprehensive and more convincing support for integrating temperature -elevation experiments of different ecosystems and assessing response and adaptation of forest carbon cycle to global warming.
