The present invention deals with the formation of Natural Organic Nano-Fertilizers with the chelated nano-nutrients to balance plant nutrition; improve water holding capacity, soil health improvement, sustainable productivity and quality improvement. The present invention involves production of eco-friendly and low cost process for the synthesis of nanoparticles of nano-nutrients by utilizing microorganisms comprising of two lab adapted strains of Aspergillus species, one lab adapted strain of Lactobacillus sp. and lactate, gluconate and proteinate salts as a source of nutrient leads to formation of metal nanoparticles (Zn, Mg, Fe and P) with the size of <20 nms. The present invention increases 12-20% of crop yield, stress tolerance of the crops, nutrient mobilization increases and 3 fold increase in nutrient use efficiency.
