MUMBAI, India, Feb. 6 -- Intellectual Property India has published a patent application (202541123462 A) filed by Nandha Engineering College, Erode, Tamil Nadu, on Dec. 8, 2025, for 'sustainable soil moisture retention using agricultural and domestic by products.'
Inventor(s) include Dr. D. Revathi; A Yoganathan; J A Jebinth; and D Boopalan.
The application for the patent was published on Feb. 6, under issue no. 06/2026.
According to the abstract released by the Intellectual Property India: "Sustainable water management plays a crucial role in modern agriculture, especially in regions facing frequent drought, irregular rainfall, and high evaporation loss. Farmers often struggle to maintain soil moisture for longer periods, resulting in reduced crop productivity and increased irrigation demand. This project focuses on the development of an eco-friendly soil moisture retention material using a combination of agricultural and domestic by-products. The selected raw materials-coconut coir, bagasse, eggshell powder, zeolite, and aloe vera gelwere chosen for their natural availability, low cost, and environmental benefits. Coconut coir is known for its high water-holding capacity and excellent aeration properties, while bagasse contributes additional absorbency and acts as a biodegradable support medium. Eggshell powder, rich in calcium carbonate, improves soil structure and reduces moisture loss by enhancing the soil's ability to bind water molecules. Zeolite, a porous mineral, plays a significant role in retaining both water and essential nutrients, ensuring slow release to the plant root zone. Aloe vera gel contains natural polysaccharides that behave like hydrogel, makingit a suitable binder and moisture-retaining agent in the formulation. The prepared mixture was incorporated into soil samples and monitored over a 14-day period. Moisture levels were recorded at regular intervals to evaluate the drying rate of treated soil compared to untreated control samples. The experimental results showed that the treated soil retained moisture for a significantly longer duration, demonstrating slower evaporation and improved water-holding performance. This indicates that the developed material can effectively reduce irrigation frequency and promote better water conservation in agricultural fields. O.verall, this project highlights a simple, cost-effective, and sustainable. approach to enhancirig soil ~oishiie iete~tion using con'iinoruy available i;a.sie materials: The formulati6n not only supports resource recycling but also contributes to climate-resilient farming practices. The outcome suggests strong potential for practical application in small-scale and large-scale agricultural systems, making it an environmentally responsible solution for future farming challenges."
