Crop growth and viability of seeds on Mars and Moon soil simulants
Open Agriculture, 2019 If humans are going to establish a base on the Moon or on Mars they will have to grow their own crops. An option is to use Lunar and Martian regolith. These regoliths are not available for plant growth experiments, therefore NASA has developed regolith ...
