MUMBAI, India, Aug. 10 -- Intellectual Property India has published a patent application (202641089544 A) filed by Srm University-Ap on July 23, 2026, for Offline Soil Fertility Assessment Apparatus And Method For Local Nutrient Estimation And Qr- Based Advisory Generation.
Inventors include Dr. Sravan S S; Ch. Manikanta Eswar; D. Venkata Lakshmi Jyoshika; K. Smitha Vagdevi; and I. V. S Kushwanth.
The application for the patent was published on July 31, 2026, under issue no. 31/2026.
Abstract: The present invention relates to an offline edge-based soil fertility assessment apparatus (104) and method (200) for generating crop and fertilizer recommendations without Internet connectivity. The apparatus (104) comprises a microcontroller (110) coupled to soil moisture, pH, electrical conductivity, temperature-humidity, and GPS sensors (112A–112D, 114), a memory (116) storing a rule-based recommendation matrix, a display (120), and a LoRa transceiver (122). The microcontroller (110) acquires soil parameters, estimates nutrient values, generates crop and fertilizer recommendations locally, and produces a QR code (118A) for immediate offline retrieval. The same information is transmitted through a LoRa communication link (124) to a Raspberry Pi-based village hub (106) for geo-tagged storage and historical analysis, thereby eliminating dependence on cloud computing and laboratory infrastructure while enabling localized agricultural advisory services.
