A novel theoretical formulation of a multifunctional nano-fertilizer spray, integrating nano-struvite (MgNH4PO4•6H2O), ammonium sulfate (NH4)2SO4, and calcium sulfate (gypsum, CaSO4•2H2O), stabilized with food-grade additives including potassium sorbate (preservative) and polysorbate-20 (spray adjuvant). Unlike conventional fertilizers, this formulation is designed to function as a slow-release nutrient source of nitrogen (N), phosphorus (P), sulfur (S), and calcium (Ca), while simultaneously acting as a protective spray against pathogens and enhancing soil and plant resilience. The present paper provides a complete theoretical synthesis pathway, chemical interactions, formulation design, potential benefits, applications in agriculture, anticipated challenges, and proposed solutions.
This research contributes to the growing field of sustainable nanotechnology in agriculture, providing a new perspective on integrating multifunctionality into fertilizer systems.
