Soil fertilizers have the potential to significantly increase crop yields and improve plant health by providing essential nutrients to the soil. The use of fertilizers can also help to improve soil structure and fertility, leading to more resilient and sustainable agricultural systems. However, overuse or improper use of fertilizers can lead to soil degradation, which can reduce soil fertility, decrease crop yields, and damage ecosystems. Thus, several attempts have been made to overcome the issues related to the drawbacks of fertilizers, including the development of an advanced fertilizer delivery system. Biopolymer aerogels show promise as an innovative solution to improve the efficiency and effectiveness of soil-fertilizer delivery systems. Further research and development in this area could lead to the widespread adoption of biopolymer aerogels in agriculture, promoting sustainable farming practices and helping to address global food-security challenges. This review discusses for the first time the potential of biopolymer-based aerogels in soil-fertilizer delivery, going through the types of soil fertilizer and the advert health and environmental effects of overuse or misuse of soil fertilizers. Different types of biopolymer-based aerogels were discussed in terms of their potential in fertilizer delivery and, finally, the review addresses the challenges and future directions of biopolymer aerogels in soil-fertilizer delivery.
土壤肥料有潜力通过向土壤提供必需养分来显著提高作物产量并改善植物健康状况。肥料的使用还有助于改善土壤结构和肥力，从而形成更具韧性和可持续性的农业系统。然而，过度使用或不当使用肥料会导致土壤退化，进而降低土壤肥力、减少作物产量并破坏生态系统。因此，人们已经进行了多次尝试来克服与肥料缺点相关的问题，包括开发先进的肥料输送系统。生物聚合物气凝胶有望成为一种创新解决方案，以提高土壤肥料输送系统的效率和有效性。该领域的进一步研究和开发可能会导致生物聚合物气凝胶在农业中得到广泛应用，促进可持续农业实践，并有助于应对全球粮食安全挑战。本综述首次讨论了基于生物聚合物的气凝胶在土壤肥料输送中的潜力，介绍了土壤肥料的类型以及过度使用或滥用土壤肥料对健康和环境的不利影响。从其在肥料输送方面的潜力出发，讨论了不同类型的基于生物聚合物的气凝胶，最后，本综述阐述了生物聚合物气凝胶在土壤肥料输送方面面临的挑战和未来发展方向。
