Synthesis of some slow-release nano fertilizers based on hydroxyapatite nanoparticles

Hydroxyapatite(HAP) nanoparticles and slow-release nano fertilizers of hydroxyapatite- Urea and Cu have been synthesized successfully by sonochemical method. In this research work we describe a strategy for sustained and slow release of nitrogen and copper into the soil. solid fertilizers wherein urea and copper are adsorbed on the surface of hydroxyapatite phosphate nanoparticles. Hydroxyapatite nanoparticles and nanofertilizers were characterized by, X-ray powder diffraction(XRD), FT-IR and scanning electron microscopy(SEM).
