Dutch researchers have been trying to simulate the soil conditions on the Moon and Mars for crop cultivation experiments  They have made a preliminary analysis of the carrots, peas, rye and tomatoes planted in the experiment  The experimental results are positive  These products are not only safe, but also may be healthier than the crops planted in the soil on earth
British media said that the hope of colonizing Mars is a step forward by growing edible crops in Martian soil
In another similar experiment, potatoes grew badly.
