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: lunar soil (or ‘regolith’) compacts in the presence of water, creating problems for plant germination and root growth.
Hydroponic farming emerges as a viable solution. This method bypasses traditional soil-based agriculture by nourishing plant roots directly with nutrient-enriched water. Nonetheless, the opportunity remains to harness lunar regolith through the principle of ‘in-situ resource utilization’—essentially, making the most of what the lunar surface has to offer for sustainable living.
