We'll soon know what kinds of crops we can grow on Mars! Bonus, the fruits will be already freeze-dried!
Handy list of preferred pH's of common garden plants. -Mike -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/

Apparently we're all going to be eating asparagus on Mars.
Stinky urine, anyone? Edit: that article has some ... interesting units. A cubic metre of soil? Blimey! |

Apparently we're all going to be eating asparagus on Mars. Stinky urine, anyone? Edit: that article has some ... interesting units. A cubic metre of soil? Blimey! That article left out half his sentence though... "Preliminary results showed the soil had a pH between 8 and 9, researchers said. A pH less than 7 means the solution is acidic, while a pH over 7 means it is alkaline. Phoenix also detected the presence of magnesium, sodium, potassium and chloride in the mixture. "It's very typical of the soil here on Earth minus the organics," Kounaves said during a teleconference from Tucson, Ariz. On Earth, asparagus, green beans and turnips could be planted in such an environment and chemical-loving bacteria would thrive there, he said. Planetary scientist David Paige of the University of California, Los Angeles, said it is too early to tell whether the minerals found in the soil could support life. Paige, who had no role in the mission, said the find was not surprising because rocks weather over time and bits of minerals mix with the soil." http://news.yahoo.com/s/ap/20080626/ap_on_...3uBRCTV7nL0kPUI |
