AsianScientist (Jul. 29, 2026) – Think about astronauts harvesting bowls of contemporary rice on the Moon. It might sound like a scene from a science fiction movie, however researchers in Japan have taken a significant step towards making it doable.
Scientists in Japan have developed a transportable gadget that turns air into fertilizer and have efficiently used it to develop rice seedlings in soil designed to imitate the Moon’s floor. The research, revealed within the journal npj Microgravity, acknowledged that the identical know-how might additionally make farming on Earth extra sustainable by decreasing our dependence on fossil fuel-based fertilizers.
Turning air into plant meals
One of many greatest challenges of rising crops on the Moon is the dearth of fertile soil. Regolith, or the Moon’s soil, accommodates no natural materials, and important plant nitrogen sources like ammonia and nitrate are nearly nonexistent.
To resolve this drawback, researchers from Tohoku College and the Japan Aerospace Exploration Company (JAXA) created a inexperienced, energy-efficient plasma know-how that produces nitrogen fertilizer from atmospheric air and electrical energy.
The gadget consumes lower than 100 watts of energy — about the identical as a vibrant mild bulb. It selectively converts nitrogen and oxygen within the air into dinitrogen pentoxide (N₂O₅), a gasoline that dissolves nearly utterly in water to type nitrate, a type of nitrogen that crops can readily take in.
“Our transportable plasma gadget selectively synthesizes dinitrogen pentoxide (N₂O₅) gasoline from atmospheric air, consuming lower than 100 W within the course of,” mentioned Toshiro Kaneko, a professor from the Graduate Faculty of Engineering at Tohoku College and co-author of the research. “This plasma-produced gasoline promptly dissolves in water to generate nitrate (NO₃⁻) with an exceptionally excessive dissolution effectivity of almost 100%.”
Serving to rice thrive in lunar soil
Kaneko and his colleagues examined whether or not the N₂O₅-dissolved water might function a neighborhood nitrogen fertilizer to develop rice seedlings inside a lunar regolith simulant.
The outcomes have been optimistic. The nitrate-rich water diminished the lunar regolith simulant’s alkalinity, decreasing its pH from 9.09 to a plant-friendly 6.76. This alteration unlocked necessary vitamins comparable to calcium, magnesium and potassium ions that had been trapped within the regolith, making them out there for plant roots.
On the similar time, the remedy diminished the discharge of aluminum ions, which might hinder root growth. The discharge of vital minerals and suppression in dangerous ones improved rice progress, particularly in comparison with rice grown utilizing pure water alone.
The researchers additionally discovered one other surprising profit. They found that the gasoline helps strengthen crops’ immune techniques and controls undesirable traits. Spraying N₂O₅ gasoline instantly onto plant leaves activated vital pure protection pathways that strengthen plant immunity. It additionally slowed extreme stem progress, producing shorter, sturdier crops which is a helpful trait within the Moon’s low-gravity surroundings, the place crops might in any other case change into weak and elongated.
Advantages past the moon
Kaneko mentioned that while the know-how is ideally suited to lunar farms, it might additionally assist cut back environmental burdens in agriculture right here on Earth.
“The method of manufacturing this fertilizer operates completely on electrical energy and low energy, utterly decoupling nitrogen fixation from fossil fuels, making the know-how appropriate for sustainable crop manufacturing on the Moon and right here on Earth,” Kaneko mentioned.
