Biosurfactant solutions for drought-resilient lawns
Mechanism-driven evaluation of biosurfactants to enhance drought resilience in lawns by improving soil wettability and hydraulic connectivity. This research aims to optimize biosurfactant use for better water retention and plant health under stress.
Overview
This solution focuses on the use of biosurfactants to enhance drought resilience in lawn and garden systems. By improving soil wettability and hydraulic connectivity, biosurfactants increase the amount of water available to plants during periods of heat and drought. This research project, conducted by Tennessee State University, provides a detailed mechanistic evaluation of biosurfactant products, linking soil physical changes to improved root function and plant stress responses. The outcome will be actionable insights into how and when biosurfactants can be applied to optimize water-use efficiency and landscape resilience.
Technical specifications
- Biosurfactants: Compounds that modify soil wettability and enhance hydraulic connectivity.
- Research methods: Controlled soil-plant experiments to assess changes in soil wettability, water retention, and unsaturated water flow.
- Performance metrics: Evaluation of root development, plant water status, turf quality, and drought recovery under stress conditions.
- Outcome: Mechanistic evidence and practical guidelines for the deployment of biosurfactants in lawn and garden systems.
Technology readiness level
This technology is at TRL 9, indicating it is ready for full-scale deployment. The research has passed through controlled experimental phases and is supported by evidence demonstrating its efficacy in improving drought resilience in landscape soils.
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.
