Researchers have discovered that lunar regolith can be transformed into usable soil with the addition of vermicompost and arbuscular mycorrhizal fungi, paving the way for potential agriculture on the Moon.
Recent research has shown promising results in converting moon regolith into usable soil by adding just a couple of key ingredients. The first ingredient is vermicompost, which consists of processed organic waste from red wigglers rich in nutrients and microorganisms beneficial to plant growth. This compost could be produced during space missions by utilizing leftover food and hygiene products that would otherwise become waste, thus supporting sustainable cultivation practices in space.
The second vital ingredient is arbuscular mycorrhizal fungi, which were applied to the surfaces of chickpea seeds before planting. These fungi form a symbiotic relationship with plants, enhancing nutrient absorption and simultaneously reducing heavy metal uptake. In experiments, researchers planted chickpeas in various mixtures of artificial regolith and vermicompost to test their growth and seed production abilities.
The results showed that chickpeas thrived and produced seeds even in mixtures with up to 75% regolith. While higher ratios of regolith led to a decrease in the number of mature seeds, the quality of the seeds remained unchanged. Notably, plants did not survive in pure regolith but managed to stay alive for an average of two weeks when paired with the mycorrhizal fungi, indicating a step forward in making lunar agriculture feasible and potentially revolutionizing food production in space.
