Abstract:
This study presents the development of eco-friendly zinc (Zn) and iron oxide (Fe?O?) nanoparticles tailored for sustainable fertilizer delivery in agriculture. Utilizing avocado seed extract as a green reducing and stabilizing agent, nanoparticles were synthesized under optimized conditions by varying precursor concentration, extract volume, reaction time, and temperature. Comprehensive characterization using SEM, FTIR and UV-Vis, confirmed desirable physicochemical features, including particle morphology, functional groups, and stability. To evaluate their application as nanofertilizers, the nanoparticles were tested for compatibility and stability in organic acid solutions—specifically fulvic acid and ascorbic acid. The findings demonstrated that the optimized nanoparticles maintained structural integrity and dispersion in these environments, highlighting their potential for efficient nutrient delivery and reduced environmental impact. This work contributes to the growing field of sustainable nanotechnology in agriculture by integrating green synthesis, stability optimization, and environmentally compatible fertilizer systems.
