Martian soil is poisonous, but there are many different methods to remove the chemical. But we are not going to talk about any of them.<br>Oh, really? I thought that the whole video is going to be dedicated on this major problem, instead of planting seeds in volcanic rocks.,(reply>), @Иван Снежков haha, I did talk about it a little more in another Martian food video I made. But it probably needs its own video! If I recall correctly the two main methods would simply be rinsing the soil and/or using bacteria that metabolise the toxic perchlorates!,(reply>), @Tommo Carroll, I hope you have a video to prove it. :P,(reply>), That could be a topic for another video for sure, but that's just not what this was about, as it is an issue that's already been solved!,(reply>), hmmm
