Agriculture must meet the growing demand for food production while minimizing environmental impacts, particularly greenhouse gas (GHG) emissions. Nanotechnology has emerged as a promising tool with diverse applications across various sectors, including agriculture. This review highlights the application of different nano-agrochemicals in agriculture, and their role in mitigating GHG emissions. This review also outlines the advantages and risks of using nanomaterials in agriculture. The bibliometric analysis revealed a lack of integrated literature addressing the role of nanotechnology in both agricultural productivity improvement and GHG emission reduction. This underscores the importance of the present review, which brings together these two critical topics under a single framework. Compared to their conventional counterpart, nano-agrochemicals have demonstrated superior performance in enhancing plant growth, yield, and protection. Moreover, their application holds significant potential for reducing GHG emissions from the agricultural sector. However, environmental impacts of nano-agrochemicals on soil nutrient dynamics, properties, and microbial communities remain a concern. Factors such as synthesis method, physicochemical properties, dosage, and particle size significantly influence the suitability of NPs for agricultural applications. Additionally, this review underscores the importance of ecological and environmental sustainability in NP use, particularly in restoring soil microbial health and optimizing NP production for GHG reduction. By critically assessing both the benefits and potential risks of nano-agrochemicals, this review provides a balanced perspective to guide future research and the development of sustainable agricultural practices.
农业必须在满足不断增长的粮食生产需求的同时，将环境影响降至最低，尤其是温室气体（GHG）排放。纳米技术已成为一种有前景的工具，在包括农业在内的各个领域有多种应用。本综述重点介绍了不同纳米农用化学品在农业中的应用及其在减少温室气体排放方面的作用。本综述还概述了在农业中使用纳米材料的优势和风险。文献计量分析表明，缺乏综合文献论述纳米技术在提高农业生产力和减少温室气体排放方面的作用。这凸显了本综述的重要性，它将这两个关键主题整合在一个框架下。与传统农用化学品相比，纳米农用化学品在促进植物生长、提高产量和保护方面表现出卓越性能。此外，其应用在减少农业部门温室气体排放方面具有巨大潜力。然而，纳米农用化学品对土壤养分动态、性质和微生物群落的环境影响仍然令人担忧。合成方法、物理化学性质、用量和粒径等因素显著影响纳米颗粒在农业应用中的适用性。此外，本综述强调了纳米颗粒使用中生态和环境可持续性的重要性，特别是在恢复土壤微生物健康和优化纳米颗粒生产以减少温室气体排放方面。通过批判性地评估纳米农用化学品的益处和潜在风险，本综述提供了一个平衡的视角，以指导未来的研究和可持续农业实践的发展。
