Is Martian soil actually good for farming?

Posted by K R on

If we ever wanted to permanently colonize Mars, one thing seems probable: we'd have to figure out how to grow some food there. This raises an interesting question: could we use Martian soil to do it? Previously, NASA researchers had speculated that we'd have to either grow food hydroponically on Mars, or ship soil there from Earth. But a new study published in the journal PLOS ONE suggests that using Martian soil might actually be a possibility. In it, researchers found that plants actually grew better in a simulated Martian soil than in nutrient-poor soils found on Earth (and Martian soil seems to be more suitable than lunar soil). Still, there are lots of caveats to consider before assuming that farming on Martian soil is a real possibility. Read more via Vox.
