Russian researchers have engineered a fertilizer derived from algae to support hydroponic plant growth. The project is being advanced by researchers affiliated with the Far Eastern Federal University, which leads the development effort.
Hydroponics and aeroponics offer a soil-free path to cultivation when traditional soil systems aren’t feasible. This approach also helps limit plant exposure to soil-borne diseases and pests, while enabling precise control over water and nutrient delivery. Yet, the success of a hydroponic crop hinges on the chosen nutrient mix and the skill with which it is applied.
The new fertilizer centers on a specific algae known for its widespread use in the food industry. It is delivered in a liquid form with a viscosity reminiscent of light soy sauce. According to the developers, the product matches the performance of conventional mineral fertilizers. “Lettuce grown with our formulation reaches comparable size to lettuce grown in standard nutrient solutions. Moreover, our fertilizer offers cost advantages and yields vegetables that are more nutritious and of higher quality,” the researchers note.
At present, the science team continues to refine the composition to enhance flavor and aroma in produce. There is also potential for the liquid to support soil-free cultivation of fresh vegetables and fruits in space habitats, expanding opportunities for food production beyond Earth.
