Can plants grow in moon soil?
Probably if treated properly. All plants need to grow is light, water and nutrients. There really is no need for soils as many plants can grow straight in a nutrient solution. It´s called hydroponics. But growing in a medium like soil is how plants usually grow and some plants, like potatoes, require it. Lunar regolith could work as a growth medium if properly treated (soil is a terrestrial term as it contains lots of organic material. There are no orgnic substances in lunar regolith). Just treating the lunar regolith with water an CO2 could make it quite safe for plants. It is bound to contain alkaline oxides. Water would turn them into caustic hydroxides but CO2 would turn them into carbonates. Carbonates are not only pH neutral but they are also pH buffers and good nutrients for plants. There might be some other exotic minerals in regolith but most of it is composed of SiO2 or glass. Actually it is made up out of microscopic chards of glass that could potentially shred the cellwalls
