Abstract
This study investigates the development of a polymer-based encapsulated urea fertilizer through the incorporation of hydroquinone as a nitrification inhibitor. The primary aim is to mitigate nitrogen losses resulting from volatilization and leaching, thereby improving the nitrogen use efficiency of conventional urea fertilizers. A polymer matrix containing hydroquinone was synthesized and employed as a coating material for urea granules. The encapsulated formulations were systematically evaluated for their nitrogen release kinetics, mechanical durability, and surface morphology. Experimental findings indicate that hydroquinone significantly delays nitrogen release while simultaneously enhancing the structural integrity of the fertilizer granules. These outcomes underscore the potential of hydroquinone-integrated polymer coatings in the advancement of controlled-release fertilizer technologies.
