Abstract

Urea is a cost-effective fertilizer used to promote plant growth and increase crop production. However, uncontrolled use of urea fertilizer is harmful to plants and can lead to soil and water pollution. This study aimed to investigate the effect of different urea concentrations on nitrogen slow release rate from electrospun Poly (L-lactide) (PLLA) nanofibers. Results showed increasing urea percentage loaded into nanofibers from 10% to 40% led to larger nanofiber diameters and increased initial rate of nitrogen release. Furthermore, nanofiber samples released nitrogen for three months, although high urea concentration did not affect the nitrogen release rate significantly.
