Growing plants in lunar soil isn't easy, but new research suggests hydroponics, with some locally sourced nutrients, could prove to be a more useful technique.
, albeit not very well. One of the main challenges is that lunar regolith lacks certain amounts of nitrogen compounds—a key ingredient in soil that allows flora to flourish. Another issue is that lunar soil gets
tightly compact when wet, which creates trouble for plants trying to put down healthy and strong roots., Norway’s Geotechnical Institute, and the Center for Interdisciplinary Research in Space are turning to hydroponics, in which plants are grown in nutrient-rich water instead of soil. This current research project is studying the best methods of leeching the nutrients out of lunar soil.The idea is that astronauts can extract nutrients in lunar regolith to create fertilizer for hydroponic farming. These nutrients could be pulled from soil using a processing plant and then dissolved into water, all on the Moon’s surface.
nutrient-rich water can then be pumped into a greenhouse for hydroponic farming, a crucial part of maintaining a“This work is essential for future long-term lunar exploration,” Malgorzata Holynska, ESA materials and processes engineer, said in. “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.
