A new European Space Agency Discovery project led by Norway’s Solsys Mining is looking into the treatment of lunar soil to create fertilizer for growing plants.
The good news is that analysis of lunar samples returned to Earth in the past by Moonwalkers and robots shows sufficient essential minerals are available for plant growth, apart from nitrogen compounds. The bad news is that lunar soil compacts in the presence of water, creating problems for plant germination and root growth.
Hydroponic farming therefore offers a practical alternative; this type of agriculture involves feeding plant roots directly with nutrient-rich water, without the need for soil. The potential is still there however to put lunar regolith to work, on the basis of ‘in-situ resource utilization’ – or living off the land.
