The growth of the human population is causing an exponential increase in the need for food. Fertilizers are one of the most important elements to meet this increased demand and to ensure global food security. Many enhanced efficiency fertilizers, such as controlled-release fertilizers (CRFs) have been developed. Although these fertilizers offer many advantages over prior generations, their high cost of production as well as unfavorable effects on the environment and soil quality have limited their use. To mitigate these issues, CRFs based on biopolymers (CRF@BB) represent a new generation of fertilizers produced by coating the granules with biopolymers. In addition to controlling the nutrient release rate, these products also enhance the soil quality and they reduce the negative effects associated with conventional fertilizers. This review summarizes the recent advances in biopolymers and derived biopolymers used in the area of CRF@BB, the coating technologies, and the parameters governing the release behavior through organic coating materials, as well as the effect of coated CRFs on the soil and plants growth.
人口增长导致对食物的需求呈指数级增长。肥料是满足这一增长需求和确保全球粮食安全的最重要因素之一。已经开发出许多增效肥料，例如控释肥料 (CRF)。尽管这些肥料比前几代肥料具有许多优势，但它们生产成本高，对环境和土壤质量的不利影响限制了它们的使用。为了减轻这些问题，基于生物聚合物的 CRF (CRF@BB) 代表了新一代肥料，它通过用生物聚合物涂覆颗粒来生产。除了控制养分释放率外，这些产品还能提高土壤质量，并减少与传统肥料相关的负面影响。本文综述了在 CRF@BB 领域中使用的生物聚合物和衍生生物聚合物、涂层技术以及通过有机涂层材料控制释放行为的参数，以及涂覆 CRF 对土壤和植物生长的影响。
