Original Abstract

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(3hydroxybutyrate), offering a gradual nitrogen release without soil pollution. Our research on controlled-release fertilizers with biodegradable coating involved coated formulations with urea and P3HB filler. We were able to prepare these pellets on a quarter-operational pelletizing device and coat them in larger quantities in a coating drum. This technology could be transferable to the industry. A careful study of the biodegradation of these fertilizer formulations in soil and research into the long-term effect on soil composition under field conditions will also be needed.
