Design products or technologies that incorporate metal nanoparticles (NPs) in agriculture need to be safe for consumers, soil microorganisms, and environment friendly. This review analyzed application advances of metal NPs in crop production and soil remediation, which are two major challenges that are constraining world sustainability and food security. The use of NPs in agriculture is also explored as a tool to improve plant productivity, control phytopathogens and viruses, monitor the quality and health of plants and soil, and seed-priming. Concerning soil remediation, this review focuses on potentially toxic element pollution when NPs are used as an assisted phytoremediation alternative, combined with electrokinetic remediation, or for acid mining drainage remediation, as well as their role in photocatalysis. In addition, it addresses the pathways of interaction with soil properties, plants, and soil microorganisms, which are relevant factors influencing NPs fate and behavior in soil and their functions. Finally, this review aimed to explore the common purposes and challenges of nanotechnology in agriculture and remediation, which may be the basis for new technologies.

在农业中加入金属纳米粒子 (NP) 的设计产品或技术需要对消费者、土壤微生物和环境友好。本综述分析了金属纳米颗粒在作物生产和土壤修复中的应用进展，这是制约​​世界可持续性和粮食安全的两大挑战。NPs 在农业中的应用也被探索作为提高植物生产力、控制植物病原体和病毒、监测植物和土壤的质量和健康以及种子引发的工具。关于土壤修复，本综述重点关注当 NPs 用作辅助植物修复替代方案、与电动修复相结合或用于酸矿排水修复时潜在的有毒元素污染，以及它们在光催化中的作用。此外，它解决了与土壤特性、植物和土壤微生物相互作用的途径，这些是影响 NPs 在土壤中的命运和行为及其功能的相关因素。最后，这篇综述旨在探讨纳米技术在农业和修复中的共同目的和挑战，这可能是新技术的基础。
