Researchers Successfully Grow Chickpeas in Simulated Lunar Soil

Scientists at Texas A&M University have successfully grown chickpeas in a soil mixture containing up to 75% simulated lunar regolith, marking a significant advancement in extraterrestrial agriculture. The research, led by graduate student Jessica Atkin, utilized a combination of simulated moondust, vermicompost, and beneficial fungi to cultivate the legumes.

The study involved planting desi chickpea seeds coated with arbuscular mycorrhizal fungi in a blend of lunar regolith simulant and vermicompost—a nutrient-rich byproduct of earthworm digestion. This combination aimed to enhance soil fertility and structure, facilitating plant growth in the otherwise inhospitable lunar-like substrate. The chickpeas matured to seed in approximately 120 days, slightly longer than the typical 100-day growth period on Earth, and exhibited signs of stress. However, the successful cultivation in high regolith concentrations is a promising step toward sustainable food production for future lunar missions.

Atkin emphasized the importance of this research for long-term space exploration, stating that the ability to grow crops in space could reduce reliance on Earth-based resupply missions and contribute to waste reduction. The findings suggest that with appropriate amendments, lunar regolith can be transformed into a viable medium for agriculture, potentially supporting astronauts on extended missions.
