Making the soil of Mars fertile

SmartGreen Space works on simulated Martian regolith: a ground with no organic matter, where a plant will not take on its own. We amend it at different doses, grow, measure, and use that data to train an algorithm that learns at what quantities the soil becomes fertile.

Why we study it

Whoever farms on Mars will not be able to bring soil with them. They will have to use what is there, and know exactly how much to add. The same question, how much a poor soil needs before it gives a harvest, holds down here too, on depleted land.
