Is Earth’s soil designed? Look what happened when we tried moon soil…

David Tyler writes to say,

Samples of dust collected in Apollo 11, 12 and 17 missions have been used to grow plants. After two days, the seeds sprouted. “I can’t tell you how astonished we were” said one of the scientists involved. By day 6, all the samples were stunted – the seedlings were suffering from ionic stresses. All this work is to “inform prospects for lunar exploration”.

I am puzzled by the astonishment expressed. Seeds can sprout without soil – all that is needed is moisture. Hydroponics replaces soil by providing water with the right minerals.

There are sites on Earth where plants experience ionic stresses: notably old mine workings. However, the processes of soil development eventually make these sites more productive. On the Moon, there is the additional factors of exposure to cosmic rays and solar wind.

It seems to me that the authors would frame their research in a more holistic way if they recognised that soil is an ecosystem:

The authors are setting out to design a fertile lunar soil, but it would help them if they recognised that soils on Earth have the marks of design.

He suggests:

    Soils are designed? Is there anything in this Universe that is not designed? If that is the case then any test for design is redundant. Even if it worked, there is no way to know since everywhere you were to try it would give a positive result.

    Earth soils are designed by plants. This can be seen every day if you look closely. Plants are always turning rock or asphalt or concrete into soil when they get a chance.

    Yes, Polistra! Change is an interaction, in this case between plants and their environment.

    And yes, Seversky, arguments over who designed what, where, when and how need to move on from the old Greek philosophy of causes.

    This is what is needed to sustain astronauts living at a Lunar outpost. That and readily accessible water. Whatever may be on the moon will need to be supplemented by at least 20 launches per day, every day, of additional water and other supplies. NASA was planning a moon base since at least 1960. More announcements regarding launches and new types of rockets – Lunar cargo rockets – should be coming soon.
