A brand-new ESA Discovery job led by Norways Solsys Mining is looking into the treatment of lunar soil to create fertilizer for growing plants. “Achieving a sustainable existence on the Moon will include utilizing local resources and gaining access to nutrients present in lunar regolith with the possible to help cultivate plants. The existing study represents an evidence of principle using readily available lunar regolith simulants, opening the method to more in-depth research study in the future.”

From Moonwalkers to Farmers: Turning Lunar Soil into Fertilizer for Hydroponic Farming
Sooner or later, settlers on the Moon will have to become farmers. A new European Space Agency (ESA) Discovery task led by Norways Solsys Mining is checking out the treatment of lunar soil to produce fertilizer for growing plants.
The bright side is that analysis of lunar samples went back to Earth in the past by Moonwalkers and robotics shows adequate essential minerals are offered for plant growth, apart from nitrogen substances. The bad news is that lunar soil (or regolith) compacts in the existence of water, developing issues for plant germination and root growth.
Hydroponic farming for that reason offers a practical option; this kind of farming involves feeding plant roots directly with nutrient-rich water, without the requirement for soil. The potential is still there nevertheless to put lunar regolith to work, on the basis of in-situ resource usage– or living off the land.
The Enabling Lunar In-Situ Agriculture by Producing Fertilizer from Beneficiated Regolith job, led by Solsys Mining with Norways Geotechnical Institute (NGI) and Centre for Interdisciplinary Research in Space (CIRiS), includes studying a combination of mechanical, biological and chemical procedures to extract mineral nutrients from the regolith. Belongings components might require concentrating before use, while unwanted ones would be removed.

” This work is necessary for future long-term lunar exploration,” comments ESA procedures and materials engineer Malgorzata Holynska. “Achieving a sustainable existence on the Moon will involve acquiring and using regional resources access to nutrients present in lunar regolith with the possible to assist cultivate plants. The existing study represents a proof of concept using offered lunar regolith simulants, breaking the ice to more comprehensive research study in the future.”
The Solsys Mining group is positive, having already cultivated beans utilizing simulated lunar highland regolith as a nutrient source.
The task happened as a concept submitted through ESAs Open Space Innovation Platform, seeking out promising originalities for area research. It is now being funded by the Discovery aspect of ESAs Basic Activities.
