The rising global food demand needs novel approaches to increasing agricultural yield while minimizing environmental effect. Phosphorus (P) is important for almost all the physiological and biochemical processes in plants. However, the phosphorus availability in soil is limited in soil due to fixation. Excess application of phosphorus-based fertilizers causes environmental hazards like eutrophication, soil degradation, damage to the aquatic ecosystem, and groundwater pollution. One of the most remarkable approaches to counter these issues could be an application of nanotechnology with special regard to nano application of phosphorus nano particles. Phosphorus nanoparticles are expected to enhance phosphorus bioavailability, thereby improving nutrient-use efficiency. These nanoscale fertilizers facilitate controlled released of phosphorus, improved plant growth, germination, and increased crop yield. Other benefits include reduced use of conventional fertilizers, therefore preventing environmental degradation in conjunction with supporting the cause of sustainable agriculture. Despite these potential benefits limited research has explored the detailed application of phosphorus nanoparticles in agriculture. This review has embarked upon the synthesis, sources, and interaction of phosphorus nanoparticles with plants, by highlighting their potential in improving seed germination, crop yield, and bioremediation. Various sources of phosphorus nanoparticles are discussed and their eco-microbiological advantages examined. The introduction of phosphorus nanoparticles in agricultural practices can be a transformative step toward a cost-effective and sustainable agroecosystem.
全球粮食需求不断增长，需要新的方法来提高农业产量，同时将环境影响降至最低。磷（P）对植物几乎所有的生理和生化过程都很重要。然而，由于土壤固定作用，土壤中可利用的磷含量有限。过量施用磷肥会导致富营养化、土壤退化、水生生态系统破坏和地下水污染等环境危害。应对这些问题最显著的方法之一可能是应用纳米技术，特别是磷纳米颗粒的纳米应用。磷纳米颗粒有望提高磷的生物有效性，从而提高养分利用效率。这些纳米级肥料有助于控制磷的释放，促进植物生长、发芽，并提高作物产量。其他好处包括减少传统肥料的使用，因此在支持可持续农业事业的同时防止环境退化。尽管有这些潜在好处，但关于磷纳米颗粒在农业中的详细应用的研究仍然有限。本综述着重介绍了磷纳米颗粒的合成、来源及其与植物的相互作用，突出了它们在改善种子萌发、作物产量和生物修复方面的潜力。讨论了磷纳米颗粒的各种来源，并研究了它们的生态微生物优势。将磷纳米颗粒引入农业实践可能是朝着具有成本效益和可持续的农业生态系统迈出的变革性一步。
