Yeah, we NEED to find a way to cheat, cheating is what will let us actually do any of this.
You need far less composting agents this way, you can add a little to a lot of moon soil to make it fertile enough for growth, and then once plants get started it will work towards making even more compost/soil.
[…] then once plants get started it will work towards making even more compost/soil.
Compost is biomaterial so it manly consists of carbon, hydrogen, nitrogen and oxygen. The only part of that you can find on the moon is oxygen, so you can’t expand beyond the amount of air and biomass (manly food) you ship from earth.
We use organic amendments all the time when reclaiming historically mined lands that did not salvage soils.
Soils take millennia to form, and you’re not going to get fertile soils without either kickstarting the process or waiting.
Another commentator points out that using arbuscular mychorrizhal fungi is also cheating. Again, how?
To have a functional soil and not regolith you need the following:
An organic matter source - regolith lacks this
A moisture retaining media - regolith usually has this but its ability varies widely
Enough rooting depth for your desired plants
A method to transform organic matter to nutrients - regolith generally lacks this
Organic matter is your pool of nutrients and microbes and fungi are what mineralize this pool into plant available forms, so saying they are cheating doesnt hold water (like a shitty regolith).
But I can grow plants in glass beads! Sure you can, but you’re supplying chemical fertilizer to do it and constantly replacing that - so in this case you’re the organic matter pool and the transformation vector.
Mixing vermicompost into the regolith seems a bit like cheating.

You can also find hydrogen in the water at the poles. Nitrogen, yep, that’s a big one.
What would you propose, then?
