This papper is about the use of biopolymer of polyvinyl alcohol (PVA) as a coat of different fertilizer granules (Azafoska 16:16:16 and Yara Kristalon 19:19:19) as a core material in presence of nitric acid. The biodegradable polymer layer provides uniform diffusion of minerals into the soil as the PVA shell decays. Scanning Electron Microscope (SEM) and Energy – Dispersive X-ray spectroscopy (EDX - 3600) were carried out for the characterization of bio-modified materials. The agrochemical changes of the soil in terms of macro-and microelements were also determined. |
