Abstract ：
Soil organic carbon (SOC) improves soil structure, retains water, and increases nutrient availability, which enhances crop productivity and serves as a significant carbon sink for climate mitigation. While it has been proposed that alterations in land use can significantly influence SOC sequestration, limited research has delved into the distinct impacts of various types of cultivated land use. The main objective of this study was to compare differences in SOC dynamics across diverse cultivated land use types in 84 counties (cities and districts) within Fujian Province, a typical subtropical area of China. This study utilizes 230,445 measured soil samples and a high-resolution 1:50,000 soil map-the most detailed database of its kind applied at the provincial scale-to simulate SOC dynamics under different cultivated land use types from 2008 to 2020. By integrating this comprehensive dataset with the DNDC (Denitrification and Decomposition) model, our approach offers greater spatial precision and more robust simulations. The results indicated that the average annual soil carbon sequestration rate (dSOC) for all cultivated land, paddy fields, dry land, and irrigated land, was 13.16, 30.98,-12.31, and-5.52 kg & sdot;ha- 1, respectively. The total change of SOC (T Delta SOC) values were 171.06 Gg and 402.80 Gg for all cultivated land and paddy fields, while they were-160.20 Gg and-71.72 Gg for dry land and irrigated land, respectively. Over the past 13 years, the interannual variations of T Delta SOC reveal a range of-263.66 to 254.71 Gg across all cultivated land in the province. Positive T Delta SOC for all cultivated land dominated from 2008 to 2016, while a shift to negative values is apparent after 2017. In general, the cultivated land throughout the province displayed a modest carbon-sink behavior. More specifically, paddy fields functioned as effective carbon sinks, while both dry land and irrigated land behaved as carbon sources. The high initial SOC content is the main direct factor negatively correlated with dSOC. Rainfall indirectly reduces dSOC by promoting an increase in clay content in both dry land and irrigated land. To improve future agricultural management, we should increase the amount of organic fertilizer applied to paddy field while maintaining economic efficiency and crop growth, and apply biochar and implement wet season drainage for both dry and irrigated land.

Abstract ：
The ecological stoichiometry of nitrogen to phosphorus ratios (N: P) plays a pivotal role in understanding elemental balance within ecological systems. Deeper understanding the dynamic changes of soil N: P ratios is vital for gaining insight into nitrogen and phosphorus cycling in ecosystems, soil management practices, and ensuring food security. This study aimed to provide a theoretical foundation for understanding of the dynamic N and P cycles within terrestrial ecosystems. Methods: The spatio-temporal variations of N: P ratios and impact factors in cropland topsoils during 1983 to 2018 in Fujian Province, China were studied and discussed by the models of geostatistics, gravity center shift and grey correlation. Results: The N: P ratios in farmland topsoils were 2.01, 2.21, and 1.80 in 1983, 2008, and 2018, respectively, exhibiting a moderate degree of variability. The gravity center of topsoil N: P ratios shifted to northwest during both 1983-2008 and 1983-2018, while it shifted to southwest during 2008-2018. Conclusions: Short-term changes in the topsoil N: P ratio was found to be influenced by N and P fertilizer applications and mean annual temperature, while the long-term changes were closely associated with soil organic matter content, mean annual precipitation, and the proportion of the primary industry. These findings offer valuable insights for formulating soil management strategies and promoting sustainable agricultural development in the study region.

Abstract ：
全球正经历以变暖为主、极端事件趋强趋频的气候变化，但其对土壤有机碳（Soil Organic Carbon,SOC）的影响并不完全一致，区分并量化极端高温和长期变暖对SOC的影响是制定适应性策略的关键。利用1︰5万大比例尺土壤数据库和DNDC(DeNitrification-DeComposition)模型，模拟了1980—2016年福建省漳州市水田土壤在气候平均态、极端高温、长期变暖及实测温度四种气候情景下SOC的动态变化。结果表明，长期变暖、极端高温及二者协同对漳州市水田SOC的净贡献量分别为13.81、–80.02和–66.14 Gg。因此，虽然在气候变暖背景下土壤仍具有较强的固碳能力，但未来频发的极端高温事件可能在一定程度上造成更大的碳损失。

Abstract ：
Background and aimsSilicon (Si) has been shown to alleviate cadmium (Cd) toxicity in plants, but the effect of Si on hyperaccumulators such as S. alfredii has not been fully elucidated. This study evaluated the impact of exogenous Si on growth, Cd accumulation, and rhizosphere properties of S. alfredii.MethodsSi was applied to S. alfredii and various parameters were assessed, including biomass, shoot Cd content, chlorophyll, carotenoid levels, malondialdehyde (MDA) content, antioxidant enzyme activity, cell wall composition, soil nutrient availability, and rhizosphere enzyme activities. A thorough transcriptomic analysis was also conducted.ResultsSi significantly increased shoot biomass (21.47-104.35%) and Cd accumulation (144.60-747.11%) in S. alfredii. Si also enhanced chlorophyll levels, reduced the malondialdehyde (MDA) content, increased antioxidant enzyme activities, and mitigated Cd-induced oxidative stress. Si boosted cell wall components, thereby facilitating Cd transport in roots. In rhizosphere soil, Si improved alkaline hydrolysis of nitrogen (AHN), available phosphorus (AP), available potassium (AK), dissolved organic carbon (DOC), and increased available Cd content. Si enhanced rhizospheric enzyme activities. Positive correlations were observed between rhizosphere nutrient availability and plant biomass, enzyme activities and Cd accumulation. Transcriptome analysis showed a higher expression of stress responsive transcription factors (WRKY, basic leucine zipper (bZIP), MYB, NAC) and genes encoding functions involved in metal transport (Heavy Metal ATPases (HMA), Copper Transporter (COPT), chelation (Phytochelatins (PCs), Metallothioneins (MTs), Glutathione (GSH)), and cell wall biosynthesis (Cellulose synthases (Ces), Pectin Methylesterases (PME)).ConclusionsSi enhanced the tolerance and accumulation of Cd in S. alfredii, underscoring its potential in phytoextraction applications.

Abstract ：
Soluble organic nitrogen (SON) plays a critical role in soil nitrogen cycling, yet the effects of Chinese milk vetch (CMV) application on the composition of SON within paddy soil profiles remains poorly understood. This study aimed to investigate the effects of varying CMV application rates on the composition and vertical distribution of SON in paddy soils, evaluating its potential implications for soil fertility and nitrogen leaching. A three-year field experiment was conducted in a subtropical rice cultivation system, employing four CMV application rates (0, 15,000, 30,000, and 45,000 kg ha-1). Soil samples were collected from three depth layers (0-20 cm, 20-40 cm, and 40-60 cm) at the rice maturity stage, and SON components, including free amino acid nitrogen (FAA-N), amide nitrogen (A-N), and soluble protein nitrogen (SP-N), were analyzed. The results demonstrated that CMV application significantly enhanced SON content, particularly in the topsoil (0-20 cm), with a 49.87% increase under the 45,000 kg ha-1 treatment. SON constituted over 50% of the total soluble nitrogen in the 0-60 cm layer, with FAA-N, A-N, and SP-N identified as the predominant components. CMV facilitated the accumulation of small-molecular SON (e.g., FAA-N and A-N) in deeper soil layers, with FAA-N content increasing by 79.13% in the 20-40 cm layer and A-N content increasing by 64.85% in the 40-60 cm layer under the 45,000 kg ha-1 treatment. In contrast, high-molecular-weight SON (e.g., SP-N) primarily accumulated in the topsoil due to stronger adsorption, while small-molecular-weight SON exhibited greater mobility, thereby elevating the risk of nitrogen leaching. These findings highlight the need for optimized CMV application rates to balance soil fertility and environmental sustainability in rice cropping systems.

Abstract ：
为探讨配施紫云英对不同类型稻田土壤溶解性有机碳（Dissolved organic carbon,DOC）和溶解性有机氮（Dissolved organic nitrogen,DON）含量的影响程度，阐明稻田土壤DOC和DON的淋溶特性，本研究以亚热带3种典型水稻土（黄泥田、灰黄泥田和灰泥田）为研究对象，通过田间试验，探讨等氮磷钾条件下单施化肥（CK）和紫云英配施化肥（cmv）处理对不同水稻土DOC和DON的动态变化、淋溶特性及损失的影响。结果表明，不同土壤类型水稻土DOC和DON的淋溶特性有所不同。3种供试水稻土中，灰泥田水稻土DOC淋溶损失量最大，其CK处理DOC淋溶损失量较灰黄泥田和黄泥田分别显著提高24.09%和72.15%,cmv处理淋溶损失量较灰黄泥田和黄泥田分别显著提高16.53%和40.55%；而黄泥田水稻土DON淋溶损失量最大，其CK处理淋溶损失量较灰黄泥田和灰泥田分别显著提高18.93%和37.01%,cmv处理3种不同类型水稻土DON淋溶损失量无显著差异。配施紫云英可显著降低水稻土DON的淋溶损失量，每季水稻中cmv处理黄泥田、灰黄泥田和灰泥田DON淋溶损失量较CK处理分别降低了24.67%、14.88%和13.54%；黄泥田cmv处理DOC较CK处理提高了19.19%，而灰黄泥田和灰泥田2种施肥处理无显著差异。供试稻田中DOC和DON在土层间的淋溶具有一定的延迟性，且DOC的延迟时间大于DON。灰色关联分析表明，在土壤性质中有机质是影响水稻土DOC淋溶损失的重要因素，孔隙度是DON淋溶损失的重要影响因素。不同类型水稻土DON的淋失早于DOC，且DON在黄泥田中淋溶损失较高，而DOC在灰泥田中淋溶损失较高；在等氮磷钾的条件下，配施紫云英可减少水稻土DON的淋溶损失，而低肥力水稻土DOC的淋溶损失量有所增加。

Abstract ：
With the acceleration of industrialization, Cd pollution has emerged as a major threat to soil ecosystem health and food safety. Hyperaccumulating plants like Sedum alfredii Hance are considered to be used as part of an effective strategy for the ecological remediation of Cd polluted soils. This study delved deeply into the physiological, transcriptomic, and metabolomic responses of S. alfredii under cadmium (Cd) stress when treated with exogenous salicylic acid (SA). We found that SA notably enhanced the growth of S. alfredii and thereby increased absorption and accumulation of Cd, effectively alleviating the oxidative stress caused by Cd through upregulation of the antioxidant system. Transcriptomic and metabolomic data further unveiled the influence of SA on photosynthesis, antioxidant defensive mechanisms, and metal absorption enrichment pathways. Notably, the interactions between SA and other plant hormones, especially IAA and JA, played a central role in these processes. These findings offer us a comprehensive perspective on understanding how to enhance the growth and heavy metal absorption capabilities of hyperaccumulator plants by regulating plant hormones, providing invaluable strategies for future environmental remediation efforts.

Abstract ：
Soil phosphorus (P) plays a vital role in both ecological and agricultural ecosystems, where total P (TP) in soil serves as a crucial indicator of soil fertility and quality. Most of the studies covered in the literature employ a single or narrow range of soil databases, which largely overlooks the impact of utilizing multiple mapping scales in estimating soil TP, especially in hilly topographies. In this study, Fujian Province, a subtropical hilly region along China's southeast coast covered by a complex topographic environment, was taken as a case study. The influence of the mapping scale on soil TP storage (TPS) estimation was analyzed using six digital soil databases that were derived from 3 082 unique soil profiles at different mapping scales, i.e., 1:50 000 (S5), 1:200 000 (S20), 1:500 000 (S50), 1:1 000 000 (S100), 1:4 000 000 (S400), and 1:10 000 000 (S1000). The regional TPS in the surface soil (0-20 cm) based on the S5, S20, S50, S100, S400, and S1000 soil maps was 20.72, 22.17, 23.06, 23.05, 22.04, and 23.48 Tg, respectively, and the corresponding TPS at 0-100 cm soil depth was 80.98, 80.71, 85.00, 84.03, 82.96, and 86.72 Tg, respectively. By comparing soil TPS in the S20 to S1000 maps to that in the S5 map, the relative deviations were 6.37%-13.32% for 0-20 cm and 0.33%-7.09% for 0-100 cm. Moreover, since the S20 map had the lowest relative deviation among different mapping scales as compared to S5, it could provide additional soil information and a richer soil environment than other smaller mapping scales. Our results also revealed that many uncertainties in soil TPS estimation originated from the lack of detailed soil information, i.e., representation and spatial variations among different soil types. From the time and labor perspectives, our work provides useful guidelines to identify the appropriate mapping scale for estimating regional soil TPS in areas like Fujian Province in subtropical China or other places with similar complex topographies. Moreover, it is of tremendous importance to accurately estimate soil TPS to ensure ecosystem stability and sustainable agricultural development, especially for regional decision -making and management of phosphate fertilizer application amounts.
