From Moonwalkers to Farmers: Turning Lunar Soil into Fertilizer for Hydroponic Farming
Sooner or later on, inhabitants on the Moon will need to end up being farmers. A brand-new European Space Agency (ESA) Discovery job led by Norway’s Solsys Mining is checking out the treatment of lunar soil to produce fertilizer for growing plants.
The great news is that analysis of lunar samples went back to Earth in the past by Moonwalkers and robotics reveals adequate vital minerals are readily available for plant development, apart from nitrogen substances. The problem is that lunar soil (or ‘regolith’) compacts in the existence of water, producing issues for plant germination and root development.
Hydroponic farming for that reason provides an useful option; this kind of farming includes feeding plant roots straight with nutrient-rich water, without the requirement for soil. The capacity is still there nevertheless to put lunar regolith to work, on the basis of ‘in-situ resource utilization’– or living off the land.
The ‘Enabling Lunar In-Situ Agriculture by Producing Fertilizer from Beneficiated Regolith’ job, led by Solsys Mining with Norway’s Geotechnical Institute (NGI) and Centre for Interdisciplinary Research in Space (CIRiS), includes studying a mix of mechanical, chemical and biological procedures to draw out mineral nutrients from the regolith. Valuable components may require focusing prior to usage, while unfavorable ones would be eliminated.

“This work is essential for future long-term lunar exploration,” remarks ESA products and procedures engineer MalgorzataHolynska “Achieving a sustainable presence on the Moon will involve using local resources and gaining access to nutrients present in lunar regolith with the potential to help cultivate plants. The current study represents a proof of principle using available lunar regolith simulants, opening the way to more detailed research in the future.”
The Solsys Mining group is positive, having actually currently cultivated beans utilizing simulated lunar highland regolith as a nutrient source.
The job happened as a concept sent through ESA’s Open Space Innovation Platform, looking for appealing originalities for area research study. It is now being moneyed by the Discovery component of ESA’s Basic Activities.
