Vegetables on Mars within ten years? The soil on Mars may be suitable for cultivating food crops – this is the prognosis of a study by plant ecologist Wieger Wamelink of Wageningen UR. This would prove highly practical if we ever decide to send people on a one-way trip to the red planet. After all, if we are going to live anywhere in outer space in the future Mars stands a good chance of being the place. In a unique pilot experiment Wieger tested the growth of 14 plant varieties on artificial Mars soil over 50 days. NASA composed the soil based on the volcanic soil of Hawaii. To his surprise, the plants grew well; some even blossomed. "I had expected the germination process to work, but I thought the plants would die due to a lack of nutrients," Wieger explains. The soil analysis showed, however, that Mars soil contains more nutrients than expected. In addition to phosphorus and iron oxides, the scientist found nitrogen, an essential plant nutrient.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
