"Where's my Shovel..." - Mars Has Ideal Conditions for Crop Farming.

Put down that Do-Nut and listen to this... According to a recent study, the planet Mars has environmental conditions that are ideal for crop farming. Okay, finish your Do-Nut fatty...
Bio-geo researchers Federico Maggia and CĂ©line Pallud have discovered that the red planet's gravity, being 1/3 of Earths's, has an affect with how water and nutrients flow through the soil...
Martian gravity is about one-third as strong as Earth’s, meaning water would flow at a slower rate. As Wired Science notes, they realized slower water transport is a good thing. Soil under Martian gravity is able to hold more water, so less of it leaches through and is lost, the authors say. This increased efficiency means you could use a whopping 90 percent less water for Martian irrigation than what you’d need on Earth. You could also use fewer fertilizers, the authors add. On the flip side, Martian soil allows for faster consumption of oxygen and dissolved organic carbon, which resulted in a 10 percent increase in CO2 emissions.
Although we are years away from even sending humans to Mars, I guess it's comforting to know we can grow some veggies up there. Science is cool...
