Bio-based microcapsules for sustained fertilizer nutrient release
This technology utilizes yeast particle encapsulation and bio-based coatings to create slow-release fertilizers, which can control nutrient delivery and stimulate plant immunity. Designed for environmentally friendly agricultural applications, this approach enhances nutrient efficiency through controlled release mechanisms.
Overview
Bio-based microcapsules for sustained fertilizer nutrient release offer a cutting-edge solution in agricultural technology. By leveraging yeast particles (YPs) for encapsulation, this technology provides a modular platform for slow-release fertilizers. The microcapsules combine YP encapsulation with bio-based coatings, such as chitosan and cardanol-derived polyurethanes, creating a controlled nutrient delivery system that also stimulates plant immune responses through the β-1,3-D-glucan content. This innovative approach not only extends the efficacy of nutrient delivery but also reduces environmental impact compared to traditional fertilizers.
