Investigators examined these the samples, exploring how fertile the ruddy surface of <\/span>Mars<\/a> <\/span>might be.<\/p>\n \u201cSimulating the mineral makeup or salt content of these Martian mixtures can tell us a lot about the potential fertility of the soil. Things like nutrients, salinity, pH are part of what make a soil fertile and understanding where Mars\u2019 soils are at in that spectrum is key to knowing if they are viable and if not, are there feasible solutions that can be used to make them viable,\u201d explained <\/span>Laura Fackrell<\/a>, UGA geology doctoral candidate and lead author on the study.<\/p>\n Plans are underway at <\/span>NASA<\/a> <\/span>to place the first humans on Mars sometime in the mid 2030\u2019s, but this crew would return to Earth as soon as possible. This group of explorers would be able to bring all the food needed with them for the journey.<\/p>\n The most ambitious plan to colonize Mars comes from Elon Musk and <\/span>SpaceX<\/a>, who plan to launch 100,000 colonists to Mars every 26 months. By 2050, the team plans to have one million people on the face of the Red Planet. Large-scale farming on Mars would require the development of significant Martian agricultural infrastructure and production methods.<\/p>\n Despite its thin atmosphere and frigid temperatures, the upper <\/span>crust of Mars<\/a> <\/span>contains many of the nutrients needed by plants, including nitrogen, potassium, and phosphorous.<\/p>\n If you think the ocean isn\u2019t important, imagine Earth without it. Mars comes to mind. No ocean, no life support system. \u2014 Sylvia Earle<\/p>\n<\/blockquote>\n However, the presence of these chemical components in soil does not mean the growing medium is good for crops. Whether or not these vital components of soil are available to plants remains an additional concern.<\/p>\n \u201cSoil on Mars is known to contain the majority of planet essential nutrients, but many questions of both the benefits (e.g. bioavailability of present nutrients) and limitations (e.g. extent of toxins) of Martian soil as a plant growth medium remain unanswered,\u201d researchers describe in an article published in the journal <\/span>Icarus<\/a>, detailing their study.<\/p>\n Simulated <\/span>Martian soil<\/a> <\/span>is dry and crusty, driving researchers to enhance the medium with beneficial bacteria and fungi for farming on Mars, as farmers might do on Earth.<\/p>\n \u201cSpecific types of bacteria and fungi are known to be beneficial for plants, and may be able to support them under stress conditions like we see on Mars,\u201d said Fackrell.<\/p>\n With the ability to grow food on <\/span>Mars<\/a>, the possibility of colonizing the Red Planet \u2014 and beyond \u2014 dramatically increases.<\/p>\n In addition to aiding in the future colonization of Mars, this new study could also aid farmers on Earth seeking to grow food in challenging environments.<\/p>\n This article was originally published on <\/span><\/i>The Cosmic Companion<\/span><\/i><\/a> by <\/span><\/i>James Maynard<\/span><\/i><\/a>, founder and publisher of The Cosmic Companion. He is a New England native turned desert rat in Tucson, where he lives with his lovely wife, Nicole, and Max the Cat.
