Abstract

In this research, we developed a novel slow-release biofertilizer by utilizing an environmentally friendly method to synthesize ZnO-NPs using sodium hydroxide, zinc acetate salt, and Lepidium sativum seed extract. The commercial fertilizer urea 46% was encapsulated in the nano-ZnO/alginate beads. The structural and morphological characteristics of the nanocomposites were confirmed using X-ray diffraction (XRD) and scanning electron microscopy, which confirmed the successful creation of nanocomposite alginate beads. The results indicated that the ZnO/alginate/urea beads exhibited a steady and continuous release of urea for up to one hour and extended nutrient availability over time. This research demonstrates the potential of ZnO-NP/alginate composites as a promising platform for developing slow-release biofertilizers, combining the beneficial properties of ZnO nanoparticles with the controlled-release capabilities of alginate matrices. This research highlights the potential of ZnO-NP/alginate composites as a sustainable and efficient solution for agricultural applications, providing a controlled release of nutrients that could minimize their environmental impact and enhance crop productivity.
