Nano/micro-structural supramolecular biopolymers show great potential in sustainable agriculture by improving soil structure, water retention, and plant nutrient uptake. These biopolymers are biodegradable, non-toxic, and can be used to develop controlled-release systems for agrochemicals, bioactive agents, and biostimulators. They can also be used as biosensors for crop protection and as carriers for fertilizers and pesticides. Supramolecular biopolymers have unique properties such as self-assembly, stimuli-responsiveness, and self-healing, which make them suitable for various agricultural applications. They can enhance plant defenses against pests and diseases by incorporating antimicrobial agents and immune-stimulating compounds. Additionally, they can improve soil health by enhancing water retention, nutrient availability, and soil structure. Supramolecular biopolymers can also be used to develop eco-friendly packaging materials that replace conventional plastic packaging. They have the potential to reduce environmental impact while improving agricultural productivity. The review highlights the potential of supramolecular biopolymers in sustainable agriculture, including their applications in soil improvement, nutrient management, and plant protection. The review also discusses the challenges and future prospects of using supramolecular biopolymers in agriculture. The study emphasizes the need for further research to optimize the use of these biopolymers in agricultural practices. The review concludes that supramolecular biopolymers offer a promising solution for sustainable agriculture by enhancing crop productivity while minimizing environmental impact.Nano/micro-structural supramolecular biopolymers show great potential in sustainable agriculture by improving soil structure, water retention, and plant nutrient uptake.
