Okey, that's not everything they said but I can't write everything in the title. NASA says Mars's soil has the nutrients for growing plants, though there may not be the right amount depending on where the astronauts land, but that could be fixed with fertilizers. The ability to obtain food plus water and oxygen would be great for a self sustained base. Can plants grow with Mars' soil?
How about the Moon? Does the Moon's soil have the nutrients for growing plants?
