Soil viruses can greatly influence both microbial catabolism and anabolism. Understanding such influences is crucial for unraveling the fate of soil organic carbon (C). However, previous studies on soil viruses have primarily focused on their role in soil C loss, overlooking their role in C sequestration. In this study, soil viruses and microbes were introduced into sterilized samples of crop and forest soils from typical red and brown soil regions of China to examine the effects of soil viruses on C dynamics, from the perspective of C release and retention. The results showed that the viral effects on soil C emissions varied between soil types. However, they significantly enhanced the accumulation of recalcitrant dissolved and metal-bound organic C, which in turn reinforced the viral effects on C emissions. Furthermore, the accumulation of dissolved and metal-bound organic C was always associated with the microbial utilization of dissolved organic nitrogen (N), highlighting the coupled C and N cycling during the viral shuttle process. Our research demonstrates for the first time the virus-mediated coupling of C and N cycling in soils and the dual role of viruses in soil C release and stabilization, providing a new understanding of virus-driven soil C cycling.

土壤病毒对微生物分解代谢和合成代谢都有很大的影响。了解这些影响对于揭示土壤有机碳(C)的命运至关重要。然而，以往对土壤病毒的研究主要集中在它们在土壤C流失中的作用，而忽视了它们在固碳中的作用。本研究将土壤病毒和微生物引入中国典型红壤和棕壤地区作物和森林土壤的消毒样品中，从碳释放和保持的角度研究土壤病毒对碳动态的影响。结果表明，病毒对土壤碳排放的影响因土壤类型而异。然而，它们显著增强了顽固溶态有机碳和金属结合有机碳的积累，这反过来又增强了病毒对碳排放的影响。此外，溶解有机C和金属结合有机C的积累一直与微生物对溶解有机氮(N)的利用有关，突出了病毒穿梭过程中C和N的耦合循环。我们的研究首次揭示了病毒介导的土壤C和N循环耦合以及病毒在土壤C释放和稳定中的双重作用，为病毒驱动的土壤C循环提供了新的认识。

Green prevention and control management of soil-borne fungal diseases is a hot topic in agriculture, ecology, and the environment. It is an important way to effectively prevent and control soil-borne fungal diseases, solve soil degradation caused by continuous cropping obstacles, and fulfill the sustainable development of agriculture through revealing the mechanisms of functional substances to develop highly effective soil amendments. Humic acid shows an inhibitory effect on soil-borne pathogenic fungi, such as Fusarium oxysporum, Choanephora cucurbitarum, and Rhizoctonia solani, with the inhibition rate exceeding 80%. The molecular and elemental composition and contents of –COOH, phenolic C, methoxy group C, carboxyl C, aromatic C–O, anomeric C, and other functional groups of humic acid have been inferred to be responsible for its inhibitory effects on pathogenic fungi in previous research. The inhibitory mechanisms mainly include cell physiological morphology, biochemical process reactions, and molecular signal transduction. This review systematically summarizes the chemical structure, fungistatic effects, variable characteristics, and inhibitory mechanisms of humic acid, aiming to provide a theoretical basis for the development of green and efficient prevention and control technologies for soil-borne fungal diseases.

土传真菌病害绿色防治管理是农业、生态、环境等领域的研究热点。揭示功能物质的作用机制，开发高效的土壤改良剂，是有效防治土传真菌病害、解决连作障碍导致的土壤退化、实现农业可持续发展的重要途径。腐植酸对土传致病真菌尖孢镰刀菌、葫芦白霉、番茄根丝核菌等均有抑制作用，抑制率达80%以上。腐植酸的-COOH、酚C、甲氧基C、羧基C、芳香族C - o、头聚糖C等官能团的分子和元素组成及含量在以往的研究中被推断为腐植酸对病原真菌具有抑制作用的原因。抑制机制主要包括细胞生理形态、生化过程反应和分子信号转导。本文系统综述了腐植酸的化学结构、抑菌作用、变异特性及抑制机理，旨在为开发绿色高效的土传真菌病害防治技术提供理论依据。

Plastic contamination has become a major environmental concern and impacts human health, and yet this is still a topic that remains largely understudied. Effects of macro- and microplastics on soil physical, chemical, and biological properties, including soil biota, are considered adverse for soils. Due to their small size and porous surface, microplastics can also be a new environmental concern because of their ability to act as carriers of contaminants or diseases. This issue has become particularly relevant in agricultural soils because antibiotics can be present in manure or other kinds of amendments applied to farmlands or adsorbed on agricultural plastics that can be incorporated into soil. Furthermore, plastic debris can serve as a pollutant and carrier of pathogens or antibiotic resistance genes because plastics can favor modifications of bacterial cell membranes, thereby posing increased risks for the environment and humans. Although a vast amount of research has been done on the role of microplastics as tetracycline or oxytetracycline carriers, no studies have considered highly mobile antibiotics such as clarithromycin and combined exposure with microplastics in soil. In addition, more research should focus on the potential impacts of global change on degradation of plastics, especially biodegradable plastics, and plastic impact on the release of contaminants.

塑料污染已经成为一个主要的环境问题，影响人类健康，但这仍然是一个很大程度上未被充分研究的话题。宏观和微塑料对土壤物理、化学和生物特性的影响，包括土壤生物群，被认为对土壤不利。由于它们的小尺寸和多孔表面，微塑料也可能成为一个新的环境问题，因为它们能够作为污染物或疾病的载体。这个问题在农业土壤中变得尤为重要，因为抗生素可能存在于粪肥中，或施用于农田的其他种类的改良剂中，或吸附在可被纳入土壤的农业塑料上。此外，塑料碎片可以作为污染物和病原体或抗生素抗性基因的载体，因为塑料有利于细菌细胞膜的修饰，从而增加了对环境和人类的风险。尽管已经对微塑料作为四环素或土霉素载体的作用进行了大量研究，但没有研究考虑到高流动性抗生素，如克拉霉素，以及与土壤中微塑料的联合暴露。此外，更多的研究应该集中在全球变化对塑料降解的潜在影响，特别是可生物降解塑料，以及塑料对污染物释放的影响。

Whilst phosphorus (P) in soil is considered to be abundant, the portion available for plant uptake constitutes less than 1% of the overall P present. To enhance crop productivity, the utilization of mineral P fertilizers has become pervasive in agriculture. Nonetheless, the escalating prices of chemical fertilizers, coupled with new European regulations prohibiting the use of P fertilizers containing cadmium, have highlighted the urgency to identify environmentally friendly products and practices for P fertilization in agricultural soils. This comprehensive review delves into the current landscape of P fertilization from agricultural, political, and economic standpoints. We recognize the potential of microbes in mobilizing P, but emphasize the necessity for more robust research to establish their effectiveness in promoting plant P uptake under real-world conditions. Additionally, we explore the role of agricultural conservation practices, such as optimal tillage, diversified cropping systems, and increased organic carbon input, in conserving P. Furthermore, this review contemplates forthcoming innovations in research. These innovations encompass the development of enhanced formulations for biofertilizers and the undertaking of more comprehensive studies within the realm of conservation agriculture. All these endeavors collectively hold the potential to augment P accessibility to plants in a sustainable manner, thereby advancing agricultural sustainability and productivity.

虽然土壤中的磷(P)被认为是丰富的，但可供植物吸收的部分只占总磷的不到1%。为提高作物生产力，无机磷肥的利用已在农业中广泛应用。尽管如此，化肥价格的不断上涨，加上欧洲禁止使用含镉磷肥的新规定，突显了在农业土壤中寻找环境友好型产品和施肥方法的紧迫性。这篇综合综述从农业、政治和经济的角度深入研究了磷肥施肥的现状。我们认识到微生物在动员磷方面的潜力，但强调有必要进行更有力的研究，以确定它们在促进现实条件下植物吸收磷的有效性。此外，我们还探讨了农业保护措施的作用，如优化耕作、多样化种植制度和增加有机碳输入，在保护P.此外，这篇综述展望了未来的研究创新。这些创新包括发展改良的生物肥料配方和在保护性农业领域内进行更全面的研究。所有这些努力都有可能以可持续的方式增加植物对磷的可及性，从而提高农业的可持续性和生产力。

Soil aggregate stability is a fundamental measure for evaluating soil structure. While numerous tests exist for assessing soil aggregate stability, ultrasonic agitation (UA) is widely recognized for its effectiveness. Nonetheless, a significant limitation of UA is the lack of standardized methodologies and stability assessment criteria, resulting in inconsistency and incomparability across studies. Several critical factors influence the assessment of soil aggregate stability, including sample preparation (e.g., drying, sieving, and settling duration), initial and final aggregate size classes, the definition of final energy form and its calculation, variations in instrumentation and laboratory procedures, and the absence of standardized criteria. Unlike some stability methods, UA produces a broad range of results, with dispersion energy varying significantly (0.5–13 440 J g^-1) across different soil and aggregate types due to divergent procedural settings. These settings encompass factors such as initial power and amplitude, temperature fluctuation, soil/water ratio, probe specification (diameter and insertion depth), and the choice of liquid used during the process. Furthermore, UA faces challenges related to limited reproducibility, raising doubts about its status as a standard stability assessment method. To address these issues, standardization through predefined procedures and stability criteria has the potential to transform UA into a precise and widely accepted method for both qualitative and quantitative assessments of soil stability. In this comprehensive review, we outline the challenges in standardizing UA, elucidate the factors contributing to dispersion energy variation, and offer practical recommendations to establish standardized protocols for UA in soil aggregate stability assessments.

土壤团聚体稳定性是评价土壤结构的基本指标。虽然存在许多测试来评估土壤团聚体的稳定性，但超声搅拌（UA）因其有效性而得到广泛认可。然而，UA的一个重要限制是缺乏标准化的方法和稳定性评估标准，导致研究之间的不一致和不可比较。有几个关键因素影响土壤团聚体稳定性的评估，包括样品制备（例如，干燥、筛分和沉降时间）、初始和最终团聚体尺寸等级、最终能量形式的定义及其计算、仪器和实验室程序的变化以及标准化标准的缺乏。与一些稳定性方法不同，UA产生的结果范围很广，由于不同的程序设置，不同土壤和团聚体类型的分散能量差异很大（0.5-13 440 J g-1）。这些设置包括初始功率和振幅、温度波动、土壤/水比、探头规格（直径和插入深度）以及过程中使用的液体选择等因素。此外，UA面临着与有限的可重复性相关的挑战，这引起了人们对其作为标准稳定性评估方法的地位的质疑。为了解决这些问题，通过预定义的程序和稳定性标准进行标准化有可能将UA转变为一种精确且广泛接受的土壤稳定性定性和定量评估方法。在这篇综合综述中，我们概述了标准化UA面临的挑战，阐明了导致分散能量变化的因素，并提出了在土壤团聚体稳定性评估中建立标准化UA协议的实用建议。

Wetland plants and their related environmental interfaces are colonized by a wide range of microbial communities, and the symbiotic system of plants and microorganisms can interact and cooperate with each other, playing an important role in environmental remediation of metal pollution, which has garnered significant attention. The dominant communities of wetland plants still have high treatment performance and survival rate under pollution conditions. Many studies show that hyperaccumulating metallophytes have the capacity to accumulate heavy metal up to several times higher than the plants in sterile soil, due to the interaction of microbes within the rhizosphere. Thus, biotechnological efforts are being explored to modify plants for heavy metal phytoremediation and to improve the adaptation of wetland plants, endophytes, and rhizospheric microorganisms to adverse environment. New phytoremediation techniques and enhanced symbiosis technique for endophytic bacteria inoculation with high efficiency are being pursued and utilized in heavy metal phytoremediation in wetland systems. Therefore, in this review, we systematically summarized the interface characteristics of wetland systems and the interaction of symbionts, with emphasis on the enhanced removal potential and regulation mechanisms of heavy metals by plant-microbe symbiosis in wetland systems, along with the applications of plant-microbiomes for heavy metal remediation in wetlands. Moreover, we explored the remediation mechanisms of combined endogenic-ecophytic microorganisms for wetland systems. In recent research, the exogeneous bacteria drastically remodeled the rhizospheric microbiome and further improved the activity of rhizospheric functional enzymes, with the metal removal at the rhizospheric region reaching up to 95%. In order to increase the effectiveness of plant-microbiome engineering in addressing wetland environmental pollution, the significance of incorporating synergistic techniques and taking a variety of environmental factors was discussed.

湿地植物及其相关的环境界面被广泛的微生物群落定植，植物与微生物的共生系统可以相互作用和合作，在金属污染的环境修复中发挥着重要作用，引起了人们的广泛关注。湿地植物优势群落在污染条件下仍具有较高的处理性能和成活率。许多研究表明，由于根际微生物的相互作用，超富集金属植物积累重金属的能力比无菌土壤中的植物高出数倍。因此，人们正在探索利用生物技术改造植物来修复重金属，并提高湿地植物、内生菌和根际微生物对不利环境的适应能力。新型植物修复技术和高效内生菌接种增强型共生技术正在被研究和应用于湿地系统重金属植物修复中。因此，本文对湿地系统的界面特征和共生生物的相互作用进行了系统的综述，重点介绍了湿地系统中植物-微生物共生对重金属的去除潜力和调控机制，以及植物-微生物群落在湿地重金属修复中的应用。此外，我们还探讨了内源-生态微生物联合修复湿地系统的机制。在最近的研究中，外源细菌极大地重塑了根际微生物群，进一步提高了根际功能酶的活性，根际区域的金属去除率高达95%。为了提高植物-微生物组工程在湿地环境污染治理中的有效性，探讨了采用协同技术和考虑多种环境因素的重要性。

Ultrahigh-resolution Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) is an advanced instrument capable of separating and determining molecular mass-to-charge ratios with sub-ppm level accuracy. A typical FT-ICR MS spectrogram can identify hundreds to thousands of formulas in a complex sample. This perspective briefly examines the application of FT-ICR MS to soil organic matter and plant biomass studies, highlighting their significant contributions to sustainable agriculture and environment. Increased analyses by FT-ICR MS of soil, agricultural biomass, and bioactive samples would provide greater insights into the distribution and changing patterns of molecular diversity within soil organic matter, as they relate to soil health issues and environmental stresses such as climate change and soil contamination. As one step toward these goals, it will open new opportunities for valorization of agricultural biomass products/byproducts, thus accelerating the development of a more circular agricultural economy.

超高分辨率傅里叶变换离子回旋共振质谱（FT-ICR MS）是一种先进的仪器，能够以亚ppm级别的精度分离和确定分子的质量电荷比。典型的FT-ICR质谱图可以识别复杂样品中的数百到数千种配方。本文简要介绍了FT-ICR质谱在土壤有机质和植物生物量研究中的应用，强调了它们对可持续农业和环境的重要贡献。增加对土壤、农业生物量和生物活性样品的FT-ICR质谱分析，将为土壤有机质分子多样性的分布和变化模式提供更深入的了解，因为它们与土壤健康问题和气候变化和土壤污染等环境压力有关。作为实现这些目标的一步，它将为农业生物质产品/副产品的增值创造新的机会，从而加速更加循环的农业经济的发展。

Black soils represent only one-sixth of the global arable land area but play an important role in maintaining world food security due to their high fertility and gigantic potential for food production. With the ongoing intensification of agricultural practices and negative natural factors, black soils are confronting enhanced degradation. The holistic overview of black soil degradation and the underlying mechanisms for soil health improvement will be key for agricultural sustainability and food security. In this review, the current status and driving factors of soil degradation in the four major black soil regions of the world are summarized, and effective measures for black soil conservation are proposed. The Northeast Plain of China is the research hotspot with 41.5% of the published studies related to black soil degradation, despite its relatively short history of agricultural reclamation, followed by the East European Plain (28.3%), the Great Plains of North America (20.7%), and the Pampas of South American (7.9%). Among the main types of soil degradation, soil erosion and soil fertility decline (especially organic matter loss) have been reported as the most common problems, with 27.6% and 39.4% of the published studies, respectively. In addition to the natural influences of climate and topography, human activities have been reported to have great influences on the degradation of black soils globally. Unsustainable farming practices and excess in agrochemical applications are common factors reported to accelerate the degradation process and threaten the sustainable use of black soils. Global efforts for black soil conservation and utilization should focus on standardizing evaluation criteria including real-time monitoring and the measures of prevention and restoration for sustainable management. International cooperation in technology and policy is crucial for overcoming the challenges and thus achieving the protection, sustainable use, and management of global black soil resources.

黑土仅占全球耕地面积的六分之一，但由于其高肥力和巨大的粮食生产潜力，在维持世界粮食安全方面发挥着重要作用。随着农业实践的不断强化和不利的自然因素，黑土正面临着加剧的退化。黑土退化的整体概况和土壤健康改善的潜在机制将是农业可持续性和粮食安全的关键。本文综述了世界四大黑土区土壤退化的现状和驱动因素，并提出了黑土保持的有效措施。中国东北平原是黑土退化的研究热点，尽管其农业开垦历史相对较短，但发表的黑土退化相关研究占41.5%，其次是东欧平原（28.3%）、北美大平原（20.7%）和南美潘帕斯草原（7.9%）。在土壤退化的主要类型中，土壤侵蚀和土壤肥力下降（特别是有机质损失）是最常见的问题，分别占已发表研究的27.6%和39.4%。除了气候和地形的自然影响外，据报道，人类活动对全球黑土的退化也有很大影响。据报道，不可持续的耕作方式和农用化学品的过量使用是加速退化进程和威胁黑土可持续利用的共同因素。全球黑土保护与利用工作的重点应是标准化评价标准，包括实时监测和预防和恢复措施，以实现可持续管理。技术和政策方面的国际合作对于克服这些挑战，从而实现对全球黑土资源的保护、可持续利用和管理至关重要。
