The development of functional nanomaterials exhibiting cost-effectiveness, biocompatibility and biodegradability in the form of nanoadditives, nanofertilizers, nanosensors, nanopesticides and herbicides, etc., has attracted considerable attention in the field of agriculture. Such nanomaterials have demonstrated the ability to increase crop production, enable the efficient and targeted delivery of agrochemicals and nutrients, enhance plant resistance to various stress factors and act as nanosensors for the detection of various pollutants, plant diseases and insufficient plant nutrition. Among others, functional magnetic nanomaterials based on iron, iron oxide, cobalt, cobalt and nickel ferrite nanoparticles, etc., are currently being investigated in agricultural applications due to their unique and tunable magnetic properties, the existing versatility with regard to their (bio)functionalization, and in some cases, their inherent ability to increase crop yield. This review article provides an up-to-date appraisal of functionalized magnetic nanomaterials being explored in the agricultural sector.
以纳米添加剂、纳米肥料、纳米传感器、纳米农药和除草剂等形式呈现的具有成本效益、生物相容性和生物降解性的功能性纳米材料的开发，在农业领域引起了相当大的关注。这类纳米材料已证明有能力提高作物产量，实现农用化学品和养分的高效靶向输送，增强植物对各种胁迫因素的抗性，并作为检测各种污染物、植物病害和植物营养不足的纳米传感器。其中，基于铁、氧化铁、钴、钴和镍铁氧体纳米颗粒等的功能性磁性纳米材料，由于其独特且可调的磁性、在（生物）功能化方面的现有多功能性，以及在某些情况下其提高作物产量的内在能力，目前正在农业应用中进行研究。本文综述了农业领域正在探索的功能化磁性纳米材料的最新情况。
