Fertilizers are crucial in meeting the increasing demand for food in agriculture. However, excessive concentrations and uncontrolled leaching of nutrients contribute to environmental pollution by increasing reactive, unassimilated nitrogen levels. This study explores the formulation and characteristics of slow-release fertilizers coated with fully biodegradable poly(3-hydroxybutyrate), offering a gradual nitrogen release without soil pollution. Calcium ammonium nitrate, a nitrogen fertilizer, was combined with selected filler materials (poly(3-hydroxybutyrate), struvite, dried biomass) and pelletized. These pellets were then coated with a solution of poly(3-hydroxybutyrate) in dioxolane, forming a thin, high-quality polymer coating. Testing revealed that some coated pellets retained excellent resistance even after 76 days submerged in water, with only 20% of the ammonium nitrate released. Pot experiments conducted in Mitscherlich vegetation vessels assessed the impact of these coated fertilizers on maize growth and soil nitrogen release dynamics. Results demonstrated that utilizing these coated fertilizers effectively supplies maize plants with necessary nutrients while ensuring the poly(3-hydroxybutyrate) coating does not impede maize growth.
