MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202641063989 A) filed by Dr. R. Kavitha; and D. Evangelin, Salem, Tamil Nadu, on May 20, for 'composite fertilizer bead from parthenium ash and fish-scale gelatin for controlled-release.'
Inventor(s) include Dr. P. K. Senthilkumar; Dr. R. Revathi; Dr. M. Shenbagam; and Dr. P. Gowsalya.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses a composite fertilizer bead system, designated Parthagel beads, comprising mineral-rich ash derived from the controlled thermal combustion of the invasive weed Parthenium hysterophorus and gelatin isolated from waste fish scales, co-formulated with sodium alginate and cross-linked through ionotropic gelation in calcium chloride solution to yield stable spherical beads for controlled-release nutrient delivery in agricultural soils. The Parthenium ash is prepared by muffle furnace combustion at five hundred to six hundred degrees Celsius and provides essential mineral nutrients including potassium, calcium, and phosphorus, while the fish scale-derived gelatin, isolated through sequential deproteinization, demineralization, and thermal extraction, functions as a biodegradable binding and slow-release matrix. Physicochemical characterization by Fourier Transform Infrared Spectroscopy, Scanning Electron Microscopy, and Energy-Dispersive X-ray Analysis confirms successful organic-inorganic composite formation. Pot experiments using Vigna radiata in lacustrine sandy loam soil demonstrate statistically highly significant enhancement of all plant growth parameters over untreated controls and commercial urea fertilizer."
