Lunar soil, is it good for plants?
I been pondering what the grey moon soil is really like and whether
you can simply "just add water" to make it suitable for plants! Seriously, does the soil on the moon need to have organic nutrients to support plants or can you turn lunar soil into growing soil just by adding water? You could argue the same for soil on Mars and the asteroids. BC |

You would need to take some earth soil with you, have a controled temp
building and mix the two and start off with the low forms of plants and slowly move upward. Best thing to do would be to take one ship's worth of good soil and set up a good growing project and then start mixing in the moon dirt(??) in with it in small amounts. Use a green crop like soybean that helps and ads food and can be used as food too. Garden in the High Mojave Desert "Bill Carson " wrote in message om...

Steve Greenhouse in Manchester UK. Is "Japanese Knotweed" (Polygonium cuspidatum) edible? Could it be genetically modified to be edible? It's the only plant I know that would stand a chance being exposed to hard radiation, a near total vacuum, no water and astronauts in big boots jumping on it. I expect it's already thriving on the Moon from micro-contamination from the Apollo landings. The Moon will shortly turn green and develope an atmosphere. You just won't be able to move up there for the damned shrubbery! ;-) What about Rhododendron ponticum? :-) Chris.B Lean-to Solar Greenhouse/conservatory in rural Denmark (erected where the sun don't shine!) ;-) |

There is no such thng as lunar "soil". Technically, the powder on the
surface of the boon and the broken rocks eneath are called "regolith" which is a soil-like material without any biological content. The same goes for Mars and the asteroids; there is no "soil", only regolith.

The same goes for Mars and the asteroids; there is no "soil", only regolith. Matthew Ota I'm not sure that's a very helpful answer. ISTM that it rather depends on what water-soluble salts, if any, are present in that material. I honestly have no idea, and I'd like to hear from someone informed on this. Intuitively, I kind of suspect that there might not be much of interest that's water-soluble in it. Where would it come from; what would create it? I rather doubt that lunar "soil"/"regiolith" (whatever the etymology of that latter word be) would happen to be rich in all the nutrients that plants need, and free of toxins.

We await informed comment. Come on Martin, when has that ever stopped us ? ;-) Steve So, after a 10 minute quick tour of experimental geology.... Regolith is the name given to any ground up covering of big rocks with little bits of powdered rock - Earth, Moon, Mars wherever. So Regolith is not a specific name for that which we conveniently can call "lunar soil" - I think we can all agree that the soil is biologically sterile. Anyway, to quote from this webpage http://lunar.arc.nasa.gov/education/...r/teacher3.htm " The regolith consists of what you’d expect from an impact-generated pile of debris. It contains rock and mineral fragments derived from the original bedrock. It also contains glassy particles formed by the impacts. In many lunar regoliths, half of the particles are composed of mineral fragments that are bound together by impact glass; scientists call these objects agglutinates. The chemical composition of the regolith reflects the composition of the bedrock underneath. Regolith in the highlands is rich in aluminum, as are highland rocks. Regolith in the maria is rich in iron and magnesium, major constituents of basalt. A little bit of mixing from beneath basalt layers or from distant highland locales occurs, but not enough to obscure the basic difference between the highlands and the maria." I wonder if it would make a neat school type demonstration to utilise a model lunar soil to grow stuff ? Steve |

[regolith] Hmm, I just wondered what the etymology was. Gotta dash out now; I admit I haven't read your post properly yet. I'll mark it "unread" and come back to it later. Thanks. Martin -- M.A.Poyser Tel.: 07967 110890 Manchester, U.K. http://www.fleetie.demon.co.uk |
