MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202621010003 A) filed by Ms. Pranali Dnyaneshwar Thite; and Mr. Paras Prakash Jadhav, Paranda, Maharashtra, on Jan. 30, for 'smart dual -action liquid system.'
Inventor(s) include Ms. Pranali Dnyaneshwar Thite; and Mr. Paras Prakash Jadhav An.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "In standard agricultural practices, fertiliser and herbicides are applied indiscriminately to the soil in order to lead to an increase in both weed and crop growth, however, the overuse of these chemicals results in a decrease in the long term productivity of the land by degrading the soil and may therefore negatively impact the development of crops as well. This industry standard practice leads to excessive use of chemicals; has increased operating costs (due to the high cost of fertilisers/herbicides); and decreased productivity of land (as a direct result of chemical usage). The invention described here is a Smart Dual-Action Liquid System to be used for precision agriculture applications. The Smart Dual-Action Liquid System consists of a combination of various types of sensors that measure soil moisture levels, pH levels, and temperature levels, plus an optional vision sensor used to indirectly measure the root zone characteristics. The Smart Dual-Action Liquid System uses a microcontroller-based control unit to process the data provided by the soil moisture levels/sensors, pH levels/sensors and temperature levels/sensors, plus the optional vision sensor, to determine when to dispense liquids through electronically-controlled microvalves or drip devices in targeted (micro-doses to deliver maximally-nutrient-filled liquid to deep root zones of plants) or specifically (deliver weed-inhibiting liquid to root zones of weeds). In addition, the Smart Dual-Action Liquid System has a built-in feedback mechanism that continuously monitors plant and soil responses, allowing the system to be adjusted as need to accommodate changes to the plants and/or soils. Overall, the Smart Dual-Action Liquid System reduces the total amount of chemicals used in the system; conserves water; preserves soil health; and maximizes productivity in plants, thereby providing businesses with a cost-effective and environmentally-sustainable solution for precision agriculture."
