Converting Air into Plant‑Ready Nitrogen
A research team has introduced a technique that transforms ambient air into ammonia and nitrate, the two primary nitrogen forms required by plants. The method employs plasma‑based electrical discharge to activate nitrogen and oxygen molecules, subsequently producing soluble fertilizers.
Laboratory trials with lunar regolith simulant
When the generated fertilizer solution was mixed with a lunar soil simulant lacking organic matter, rice seedlings successfully germinated and grew. Measurements of leaf area and root development were comparable to those observed under terrestrial conditions.
Implications for sustainable lunar habitation
Being able to harvest nitrogen directly from the thin lunar exosphere could dramatically reduce reliance on Earth‑supplied nutrients, supporting closed‑loop food production on future lunar bases. Since the Moon’s surface contains virtually no ammonia or nitrate, this approach addresses a critical gap in resource availability.
Future work and scalability
The next phase involves testing the system in simulated lunar environments that replicate low gravity and extreme temperature cycles. Researchers also aim to improve conversion efficiency and extend the technology to other staple crops.
