Fertilizers are essential for meeting agricultural food demand, but excessive nutrient leaching increases environmental pollution. This study examines slow-release fertilizers coated with biodegradable poly(3-hydroxybutyrate) (P3HB) to ensure gradual nitrogen release without soil contamination.Pelletized urea was coated with P3HB in dioxolane, forming a durable polymer layer. Some coated pellets maintained resistance after 76 days in water. Pot experiments in Mitscherlich vessels assessed maize growth and soil nitrogen release, showing the coating did not hinder plant development. Pellets with 50% fertilizer and 50% P3HB exhibited excellent resistance, releasing only 20% of urea after 76 days. Compared to polymer-based coatings reviewed by Lawrencia et al., our formulation demonstrated controlled fertilizer release. By adjusting filler content and coating thickness, we tailored agrochemical release, with potential applications in seed protection. Results confirm coated fertilizers improve nutrient efficiency, reduce nitrogen loss, and minimize pollution while providing sustained nitrogen delivery. Large-scale pelletizing and coating processes suggest industrial feasibility. Further research is needed on soil biodegradation and long-term field effects.
