Development of Controlled Release fertilizers using engineered coatings

With the rapid growth in the global population, to maintain adequate food supply, an increasing amount of nitrogen-based fertilizers (mostly urea) is required. Due to the high solubility of nitrogen-based nutrients in water, not only is the efficiency of these fertilizers for plant growth low, but additionally ammonia volatilization causes air and water pollution. Controlled Release Urea (CRU) using engineered coating is regarded as a potential candidate to solve both the durability and the environmental questions due to their beneficial features. This includes reducing application dosage, prolonging nutrient release time, reducing time waste, reducing environmental pollution, and so on. The main objective of my research is to develop a generation of smart fertilizers by facile self-assemblies of polyphenolic compounds, which are highly biocompatible and low-cost to address the fast dissolution of urea in water and soil environment.

Omid Mazaheri has a Bachelor of Science in Applied Chemistry (2010) and the Master of Science (2013) in Organic Chemistry on the synthesis of solid acid catalysts (i.e., hierarchical zeolites, functionalized mesoporous silica, and mesoporous carbon and polymers) from Islamic Azad University (Iran). He has worked as a researcher at different universities and companies where he specialized in heterogeneous acid-metal bifunctional catalysts and nanocomposites and their applications in organic reactions and heavy metal removal from water and soil. He is currently undertaking his Ph.D. under Assoc. Prof. Helen C. Suter, Assoc. Prof. Kathryn A. Mumford, and Prof. Deli Chen at the University of Melbourne. His thesis focuses on biocompatible materials development for advanced fertilizer technology to enhance the efficiency of fertilizers by controlling the release rate of nutrients in soil.
