let it be more general!

Is the red planet conducive to cultivating green spaces? At Wageningen University in the Netherlands, researchers artificially reconstituted the soil of Mars, using samples brought back by the Viking 1 probe, to grow flowers and vegetables there.
The results of the study are surprising to say the least: plants seem to grow better in the recomposed soils of Mars than from the soil of our dear planet Earth. To explain this phenomenon, Wieger Wamelinck, the research coordinator, recalls that “plants need phosphorus, calcium and potassium. We find it on Mars and in the soil of the Moon, but the concentration is much stronger on Mars and that's why it grows so well. ” On the other hand, "the earth used for the earth's soil looks like river soil, quite poor in minerals", which slows plant growth.
Once this postulate is stated, there remains a major problem. The soil of Mars is very rich in heavy metals, the plants produced are therefore very toxic. So that "we can grow tomatoes, but they would contain so much heavy metals that they would be toxic and inedible", says Wieger Wamelink
