Kinetics of slow release of nitrogen fertiliser from multi-layered nanofibrous structures

Abstract Fertilisers are essential in modern agriculture to enhance plant growth, crop production and product quality. Recent research has focused on the development of delivery systems designed prolong fertiliser release. This study introduces a new technology encapsulate release molecules fertilisers by using multi-layered electrospun nanofibre as carrier. Single-layer poly L-lactic acid (PLLA) nanofibres loaded with urea were fabricated electrospinning. Triple-layer nanofibrous structures produced electrospinning polyhydroxybutyrate (PHB) external layers PLLA impregnated middle layer. Scanning electron microscopy (SEM) Fourier transform infrared spectrophotometry (FTIR) employed characterize morphology nanofibres. Urea dynamic was analysed total nitrogen instrument (TNM-1). The results indicated that triple-layered urea-impregnated led lower initial rate slower cumulative which extended for more than three months. It is concluded triple-layer have potential slow fertilisers.
