Advancing sustainable food production in soilless environments
Land-grant universities across the nation are working to make the food supply more secure by exploring the best ways to produce crops without soil. Hydroponic and aquaponic systems have many benefits, including reducing the inputs and space needed to produce food. Researchers are studying how to make the foods grown in these controlled environments safer and better. Extension personnel are taking the message to the public, helping them learn to implement these soilless systems.
Here are a few examples of that work:
- In an effort to boost local food production in Guam, researchers are studying aquaponics, a system that produces both plants and fish as food while using 90% less water than traditional agriculture. Researchers are evaluating three approaches to aquaponics that use different equipment setups to determine which methods are most efficient, affordable and durable.

In Ohio, researchers studied microbial dynamics in hydroponic systems and identified beneficial microbial species that promote plant health and mitigate disease and food safety risks.

The indoor farm facility is open to tours and features a model hydroponic system that beginner producers can easily reproduce at home using supplies from a hardware store.

The initiative is important as urban and rural producers alike cope with soil limitations due to natural disasters such as flooding and wildfires, which affect their productivity and profitability.
