Nowadays sustainable nanotechnological strategies to improve the efficiency of conventional agricultural practices are of utmost importance. As a matter of fact, the increasing use of productive factors in response to the growing food demand plays an important role in determining the environmental impact of agriculture. In this respect, low-efficiency conventional practices are becoming obsolete. On the other hand, the exploitation of nanoscaled systems for the controlled delivery of fertilizers, pesticides and herbicides shows great potential towards the development of sustainable, efficient and resilient agricultural processes, while promoting food security. In this context, lignin - especially in the form of its nanostructures - can play an important role as sustainable biomaterial for nano-enabled agricultural applications. In this review, we present and discuss the current advancements in the preparation of lignin nanoparticles for the controlled release of pesticides, herbicides, and fertilizers, as well as the latest findings in terms of plant response to their application. Special attention has been paid to the state-of-the-art literature concerning the release performance of these lignin-based nanomaterials, whose efficiency is compared with the conventional approaches. Finally, the major challenges and the future scenarios of lignin-based nano-enabled agriculture are considered.
如今，采用可持续的纳米技术策略来提高传统农业生产效率至关重要。事实上，为满足不断增长的粮食需求而增加生产要素的使用，在决定农业对环境的影响方面起着重要作用。在这方面，低效的传统做法正逐渐过时。另一方面，利用纳米级系统来控制肥料、农药和除草剂的释放，在发展可持续、高效和有韧性的农业生产过程以及促进粮食安全方面显示出巨大潜力。在此背景下，木质素——尤其是其纳米结构形式——作为用于纳米农业应用的可持续生物材料可发挥重要作用。在本综述中，我们展示并讨论了制备用于控制释放农药、除草剂和肥料的木质素纳米颗粒的当前进展，以及植物对其应用的反应方面的最新研究结果。我们特别关注了有关这些木质素基纳米材料释放性能的前沿文献，将其效率与传统方法进行了比较。最后，考虑了基于木质素的纳米农业面临的主要挑战和未来前景。
