Abstract

Growing environmental pollution and non-sustainable materials has escalated the need for research in sustainable practices for many areas including crop production and fertilization. The conventional coating for the controlled-release fertilizers (CRFs) is non-biodegradable. Hence, the development of novel biodegradable coatings for fertilizer prills has emerged as an important area of study. In this thesis, conducting synthesis and application of cellulose esters (biomass membrane) as an encapsulation for the controlled release fertilizers. Therefore, the coating would be effective for a controlled release of nutrients to the crops by sustaining nature. Here, synthesized biodegradable cellulose esters by 8 and 16-carbon fatty acids and applied them as a coating on the fertilizer prills, so we could control its release. The integrated cellulose esters are characterized and analyzed as a membrane for fertilizer prills, which enhances the controlled release time by minimizing the environmental effects
