Bridging Green Intelligent Fertilizers and Nutrient Intelligence for Climate-Smart Food Systems.

Green Intelligent Fertilizers (GIFs) represent a paradigm shift from passive nutrient delivery to intelligent, responsive systems, advancing from nanoscale engineering toward green sustainability. This review presents a multidisciplinary GIF technology system integrating advanced materials science, intelligent responsiveness, targeted application strategies, and precision nutrient release. GIFs mark a fundamental evolution from passive encapsulation to responsive delivery. Innovations driving this transition include environment-triggered release mechanisms, such as those responding to pH, enzymes, or temperature, for adaptive nutrient supply. By integrating delivery systems such as liposomes, polymeric micelles, nanoemulsions, and microneedles, we aim to construct an efficient, responsive, eco-friendly nutrient platform scalable for industrial production and validated under real-field conditions. Integrating advanced carriers, we build scalable, eco-friendly platforms. Overcoming field inconsistencies, ecological risks, and regulatory gaps requires merging materials science, plant nutrition, and policy to decouple productivity from pollution, advancing climate-smart agriculture.
