We Might Be Able To Grow Edible Food In Martian Soil

In a dystopian future where we’ve depleted the shrinking resources of our home planet and a few lonely, intrepid survivors are trying to eke out an existence on Mars, at least the vegetables won’t kill us. Probably. New research from scientists at Wageningen University in the Netherlands found that radishes, peas, tomatoes and rye grown in soil formulated to simulate the soil on Mars were safe to eat. The "Mars" dirt was enhanced with some organic matter from Earth that isn't present in soil from the red planet. The researchers have said previously that people colonizing Mars could theoretically bring small amounts of organic matter with them to assist in growing crops.  For the study, researchers grew 10 different crops in the Mars-like soil. Some scientists feared that the heavy metals present in the dirt — like lead, copper and cadmium — would contaminate the food. But researchers announced Thursday that the four items they tested were were safe for human consumption, based on standards set by the Dutch Food Agency and the U.S. Food and Drug Administration. More funding is needed to test the remaining six crops. "These remarkable results are very promising" ecologist Wieger Wamelink said in a news release. But don’t sign up for a Martian gardening class just yet. The study has not yet been formally written up or published, ecologist Wamelink told The Huffington Post in an email, which means it hasn’t been peer...
