Smart soil monitoring for efficient urban agriculture
Developing low-cost sensor technology for real-time soil moisture monitoring to optimize irrigation in urban food production, conserve water, and improve plant health. Fully scalable for diverse growing environments, enhancing sustainability and efficiency.
Overview
The smart soil monitoring system is designed to revolutionize urban agriculture by providing real-time moisture data to growers. This innovative technology addresses the common issue of water wastage in above-ground and container-based vegetable production. By alerting users as their growing media approach critical dryness levels, it enables precise irrigation, conserving water and enhancing plant health. This sustainable approach reduces labor, runoff, and supports improved decision-making, making it ideal for urban farms, nurseries, and home gardeners.
Technical specifications
- Real-time soil moisture monitoring: Sensors provide instant data on moisture levels via a personal device, allowing timely irrigation interventions.
- Scalable system: Additional sensors can be added to accommodate gardens of any size, offering flexibility for various growing environments.
- Compatibility with growing media like Scotts Miracle-Gro: Optimizes water retention and plant growth in containers and raised beds.
- Dashboard integration: Accompanying data dashboard for comprehensive moisture level tracking and management.
- Controlled trials and field testing: Includes greenhouse trials and collaboration with local nurseries to refine sensor technology and establish effective moisture thresholds.
Technology readiness level
This sensor-based technology is at Technology Readiness Level 6, indicating a prototype demonstration in a relevant environment. Ongoing trials and user feedback will guide further development and optimization for commercial deployment.
About Tennessee State University
Tennessee State University conducts applied and fundamental research across agriculture and environmental sciences, engineering and computer science, education and learning sciences, and health and behavioral studies. Its land‑grant programs include agricultural research and Cooperative Extension with long‑running USDA‑supported projects in plant science, urban agriculture, food safety, and natural resource management. Notable research units include the College of Agriculture’s research programs and extension centers, the Center of Excellence for Learning Sciences, and the Center of Excellence in Information Systems, along with specialized facilities such as the Otis L. Floyd Nursery Research Center. TSU investigators regularly secure funding from federal agencies including USDA‑NIFA, NSF, NIH, and the State of Tennessee, often in partnership with regional industry and community organizations. Technology transfer and outreach emphasize practical solutions in sustainable agriculture, biotechnology, data and information systems, and workforce development for Middle Tennessee and beyond.
