The present invention relates to a chelated fertilizer composition for enriching Iron and Phosphorus content in agriculture/horticulture crops and plants through foliar application. The fertilizer composition is prepared using compounds comprising chelating agent and Ferric Oxide (Fe2O3). The chelation of Fe by disodium salt of Hydroxy Ethylidene Di Phosphonic Acid (Na2 HEDP) developed 17% to 18% Fe-HEDP and 31% Phosphorus pentoxide (P2O5). The final chelated fertilizer composition obtained is in powder form and is 100% water-soluble concentrate. The chelated fertilizer composition can be used to cure Iron and Phosphorus deficiency in crops and plants, increase yield with more Iron and Phosphorus content, thus reducing the risk of Iron and Phosphorus deficiency in humans.
