Natural organic nano-fertilizers and their process of production

A process for producing an organic nano-fertilizer with chelated nano-nutrients, comprising:

• (i) producing biomass from fermentation of Aspergillus versicolor NCIM-698 in potato dextrose medium, filtering the biomass and collecting filtrate as a bioactive solution which comprises nano composites from the biomass;
• (ii) forming lactate and gluconate salt solutions, wherein Lactobacillus delbrueckii NCIM 2025 is used under anaerobic fermentation conditions to produce lactic acid fermentation product and then fortifying the lactic acid with zinc, magnesium and iron to produce zinc lactate, magnesium lactate and ferrous lactate salt solutions;
• and wherein Aspergillus niger NCIM-704 is used under aerobic fermentation conditions to produce gluconic acid fermentation product and then fortifying the gluconic acid with zinc, magnesium and iron to produce zinc gluconate, magnesium gluconate and ferrous gluconate salt solutions;
• and
• (iii) incubating the salt solution of (ii), a phosphorus proteinate hydrolysate solution, and the filtrate of (i) together for 24-48 hours at 100-120 rpm to produce the organic nano-fertilizer with chelated nano-nutrients having a nanoparticle size of 20 nm or less.
