The development of alginate-based composites in agriculture to combat nutrient loss and drought for sustainable development has drawn increasing attention in the scientific community. Existing studies are however scattered, and the retention and slow-release mechanisms of alginate-based composites are not well understood. This paper systematically reviews the current literature on the preparation, characterization, and agricultural applications of various alginate-based composites. The synthesis methods of alginate-based composites are firstly summarized, followed by a review of available analytical techniques to characterize alginate-based composites for the attainment of their desired performance. Secondly, the performance and controlling factors for agricultural applications of alginate-based composites are discussed, including aquasorb, slow-release fertilizer, soil amendment, microbial inoculants, and controlled release of pesticides for pest management. Finally, suggestions and future perspectives are proposed to expand the applications of alginate-based composites for sustainable agriculture.
在农业中开发基于海藻酸盐的复合材料以对抗养分流失和干旱以实现可持续发展，这在科学界引起了越来越多的关注。然而，现有的研究较为分散，并且对基于海藻酸盐的复合材料的保留和缓释机制了解得还不够透彻。本文系统地回顾了关于各种基于海藻酸盐的复合材料的制备、表征和农业应用的现有文献。首先总结了基于海藻酸盐的复合材料的合成方法，然后回顾了现有的分析技术，以对基于海藻酸盐的复合材料进行表征，以达到其所需的性能。其次，讨论了基于海藻酸盐的复合材料在农业中的应用的性能和控制因素，包括Aquasorb、缓释肥料、土壤改良剂、微生物接种剂和农药的控释以进行害虫管理。最后，提出了建议和未来展望，以扩大基于海藻酸盐的复合材料在可持续农业中的应用。
