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 co-contamination of arsenic (As) and cadmium (Cd) in paddy soils threatens rice safety, yet synergistic mitigation strategies using silicon (Si) and ferrous sulfate (FeSO4) remain underexplored. This study integrated hydroponic and soil pot experiments to evaluate Si-FeSO4 interactions on As/Cd accumulation and rice growth. Hydroponic trials employed 21-day-old rice seedlings exposed to 0.5 mg As(III)/Cd(II) L-1 with/without 70 mg Si L-1 and 30-70 mg Fe L-1, followed by sequential harvesting at 14 and 21 days. Soil experiments utilized co-contaminated paddy soil (50 mg As kg(-1) and 1.2 mg Cd kg(-1)) amended with Si (80 or 400 mg kg(-1)) and Fe (100 or 1000 mg kg(-1)), with pore water dynamics monitored over 120 days. Hydroponic results demonstrated that 70 mg Si L-1 combined with 30 or 70 mg Fe L-1 enhanced shoot biomass by 12-79% under As stress, while simultaneously reducing shoot As concentrations by 76-87% and Cd concentrations by 14-33%. Iron plaque induced by FeSO4 exhibited contrasting adsorption behaviors: hydroponic roots immobilized both As and Cd (p < 0.01), whereas roots in soil primarily retained Cd (p < 0.05). In soil experiments, the optimal treatment of 100 mg Fe kg(-1) and 400 mg Si kg(-1) (Fe-1 + Si-2) increased grain biomass by 54%, while reducing As and Cd concentrations by 37% and 42%, respectively. However, a higher Fe dosage (Fe-2: 1000 mg kg(-1) Fe) paradoxically increased grain Cd concentrations. Mechanistically, Si amendment elevated soil pH (Delta + 0.72), facilitating Cd immobilization, while FeSO4 lowered pH (Delta-0.07-0.53), increasing Cd mobility. A strong correlation between soluble Cd and plant uptake was observed (p < 0.01), while changes in As accumulation were unrelated to aqueous behavior. The optimized Si/Fe molar ratio of 7.95:1 effectively mitigated As and Cd co-accumulation, offering a dual-functional strategy for safe rice cultivation in contaminated soils.

Abstract ：
Land-use change (LUC) is a significant contributor to the increase in atmospheric CO2 concentrations, with previous studies demonstrating its profound impact on soil organic carbon (SOC). The conversion of primary forests to farmland has been recognized as the most significant type of LUC inducing CO2 release from the soil. Therefore, it is critical to understand the impacts of forest LUC on SOC storage, with a particular focus on primary forest to farmland conversion. In this study, we conducted a meta-analysis of 411 observations from 41 published works and found that SOC storage decreased significantly following the conversion of primary forests to farmland. Factors such as soil depth and climate zone influenced the degree of SOC storage loss, with SOC loss being less severe in deeper soil following a conversion from primary forests to farmland. Moreover, the loss of SOC storage was more severe in temperate regions compared to tropical regions. The input and output of surface SOC, changes in soil structure, and increases in atmospheric CO2 concentrations were significant reasons for the loss of SOC following primary forest to farmland LUC. However, improving tillage methods and implementing sustainable agricultural management strategies can help reduce SOC loss. These findings highlight the importance of sustainable land-use practices in mitigating the negative impacts of forest LUC on SOC storage and the global carbon cycle.

Abstract ：
There is still an incomplete comprehension of the synergistic effects of two common meteorological, temperature (T) and precipitation (P), on soil organic carbon (SOC) stocks. The DeNitrification-DeComposition (DNDC) model is a process-based model for carbon (C) and nitrogen biogeochemistry in agricultural ecosystems and has been well validated. In this study, the DNDC model was applied to explore the synergistic contribution of T and P to SOC changes in paddy soils for 37 years on the southeast coast of China, Fujian Province, using the soil database with high-resolution at 1:50,000. We have found that the total SOC changes decreased by 11.59% (10.22 Tg C), and 19.72% (9.28 Tg C) from 2017 to 2053 under scenarios where T increases 2°C and P simultaneously increases and decreases by 20%, respectively, compared to the C sequestered in paddy soils under conventional management scenario with 11.56 Tg C. Results also indicated that the SOC changes in paddy soils along Fujian's southeast coast (e.g. Putian and Quanzhou) are more dramatic than those in inland northwest regions (e.g. Nanping and Sanming). Furthermore, as T increases, the C sequestration capacity of paddy soils declines steadily but becomes more sensitive to changes in P. Specifically, combining warming with P decrease accelerated SOC loss, but increased P might mitigate slightly the SOC loss induced by warming. However, paddy fields always had a long-term role in absorbing atmospheric CO2 under all scenarios in our study. Moreover, SOC changes within different paddy soil groups respond differently to P and T combined effects or applied separately. It is hoped that this study will contribute to a better understanding of soil carbon sequestration and help policymakers identify alternative scenarios for mitigating climate change and promoting a carbon-neutral sustainable development in China. © 2023, The Authors.

Abstract ：
明确不同秸秆还田量对土壤“碳汇”的贡献大小是合理制定农业碳中和措施的基础。以我国典型亚热带地区——福建省水田土壤为研究对象，基于2016年15833个土壤样点实测数据和目前该地区最详细的1︰5万大比例尺土壤数据库，运用农业生态系统中广泛使用的DNDC(DeNitrification and DeComposition)模型模拟了不同秸秆还田率下全省未来的土壤有机碳动态变化。结果表明，2017—2053年传统管理（15%）以及秸秆还田30%、50%和90%下水田土壤的年均固碳速率分别为173、302、478和838 kg·hm~(-2)，固碳总量分别为11.56、20.15、31.90和55.95 Tg。从土壤亚类来看，咸酸和盐渍水稻土的年均固碳速率最大，不同秸秆还田率下介于220～920kg·hm~(-2)·a~(-1)之间；而渗育和潴育水稻土的固碳量最大，不同秸秆还田率下合计介于9.45～45.52 Tg之间，约占研究区总固碳量的81%。从行政区来看，龙岩、泉州两个地级市的固碳速率和总量均最大，不同秸秆还田率下均分别在202～937 kg·hm~(-2)·a~(-1)和1.55～8.34 Tg之间。总体而言，福建省水稻土亚类和行政区在不同秸秆还田率下的固碳潜力差异很大，应有针对性制定“固碳减排”管理措施。

Abstract ：
水稻土磷素流失引起的水体富营养化等生态风险已受到普遍关注，而明确其动态变化和富集效应是制定合理防控措施的基础.以福建省1.8×10~6 hm~2水稻土为研究对象，以1982年全国第二次土壤普查1 471个、 2008年农业农村部测土配方施肥项目215 534个和2018年农业农村部耕地质量监测项目2 895个表层水稻土样点建立的1∶5万三期大比例尺土壤数据库为基础，分析全省水稻土有效磷含量近40年来的富集效应及潜在生态风险.结果表明，1982～2018年间福建省水稻土有效磷含量增加了47 mg·kg~(-1),富集面积达到1.65×10~6 hm~2,占全省水稻土总面积的91%;其中，1982～2008年福建省水稻土有效磷含量增加了28 mg·kg~(-1),富集面积为1.47×10~6 hm~2,占全省水稻土总面积的82%; 2008～2018年福建省水稻土有效磷含量增加了19 mg·kg~(-1),富集面积为1.22×10~6 hm~2,占全省水稻土总面积的69%.进一步的潜在生态风险评估表明，2008～2018年全省处于磷素富集生态风险的水稻土面积呈逐增加趋势，且主要分布于坡度低于2°的渗育和潴育水稻土，今后应根据不同水稻土亚类和地形地貌区制定有效的磷施肥管理措施，以防止水体富营养化等环境问题发生.

明确土壤固碳速率和潜力是制定耕地固碳减排措施的基础。以我国典型亚热带地区—福建省不同地理位置的闽侯、浦城、同安、武平和永定5个县为研究区，运用生物地球化学过程模型DNDC(De Nitrification and Decomposition），模拟这5个县在目前区域尺度最详细的1︰5万土壤数据库下1980—2009年和2010—2039年有机碳动态变化，并运用尺度上推的方法估算出全省耕地土壤固碳速率和潜力。结果表明，福建省耕地土壤1980—2009年的固碳总量为7.37 Tg，而2010—2039年的固碳潜力为7.04 Tg，两个时段的年均固碳速率分别为190 kg·hm~(–2)和176 kg·hm~(–2)，说明目前的农田管理措施有利于研究区长期固碳。其中，水稻土和盐渍水稻土分别在土类和亚类级别中固碳速率最大，不同时段均大于175 kg·hm~(–2)·a~(–1)；而红壤在土类和亚类级别中固碳速率皆最小，不同时段均小于3 kg·hm~(–2)·a~(–1)。总体来看，1980—2009年和2010—2039年水稻土的固碳总量均占全省耕地固碳总量的92%以上，是今后制定固碳减排措施的重点。
