Yeah?

oh wow the glass-tower office buildings we constructed when we thought air conditioning and central heating would never have downsides...have downsides?

and we're still building them?

while the Victorian house museum where I work, with thick walls and small windows and big wooden shutters stays ~10 degrees above (winter) or below (summer) the outside temperature for days on end with no help at all?

uh. okay then

on nostalgia

You do not understand

Most modern Ag operations don’t even have a proper A-Horizon. They’re too busy turning the earth every time they replant. The A-horizon is the Black Gold that makes Soil Soil. It’s a structurally complex soil horizon that must be built in place by the interactions of Plants and Fungi and Insects. It is The Thing that soaks up rain and holds onto it for plants. The A-Horizon is The Thing that builds up when you let a field sit fallow. The act of tilling creates fecundity by breaking up the A-horizon. On a really good Organic no-till farm you might find an A-horizon between 3-6 inches.

His A-horizon was 4 feet deep. 50 inches.

I-

I have no context. His farm was covered in a living skin thick enough for a child to stand in.

Gives me hope for what we could accomplish if we got our collective heads on straight, you know? Like. This was one guy. A brilliant man, who knew what he was up to, but. The thing about brilliant ideas is they can be shared.

Humus, or Humic Compounds, are a cryptic and poorly understood set of organic substances. As the final metabolic result of once-living things being digested first by macroscopic organisms, and then by microorganisms, they resist most forms of analysis, and have cryptic structures. A few that we have managed to isolate and study are the Humic & Fulvic Acids.

Humus has a number of remarkable tendencies. It is capable of retaining water far better than any raw mineral clay; it also retains electrically charged clay granules, which themselves retain mineral ions, all of which is essential to make a soil a high-quality resource for Plants to grow in.

A composter is a box that contains an environment that is conducive to the production of Humus, but the best way to produce it is in-place, by laying layers of organic material down over an unbroken earth and growing things out of that. The interaction of the plants rooting, the fungus weaving itself through everything, the bacteria and archaea metabolizing as they do, and inorganic weathering forces all combine to gradually build up the microscopic equivalent of a complex megastructure capable of retaining far more water, and containing far more nutrients, than any inorganic substrate.

This stuff is black gold. This is the stuff that determines whether or not a plot of land is going to be “productive.” The knowledge of how to make it, how to care for it, is an essential piece of wisdom that our civilization needs to remember.

Fortunately, folks seem to have the right response:

Farmers are more important to the continuity of civilization than administrators, no matter what the elitists say. This knowledge is important.

* New student, very small. Grace said it was pebble. Pebble is small Earth rock. Pebble likes name.

* He found out Eridians have no gender rules.

* Students brought him mineral sample. After he stopped crying he said he loves show-and-tell game. Human naming conventions oddly literal.

* I told him Earthsun grew bright.

* I took him up atop atmosphere bypass elevator to look at stars.

* He woke up from nap and found me still with him. I did not wait on his chest; he says I am heavy like “elephant” and he “couldn’t breathe.” I laid my arm over him instead, kept him close, feeling safe. He said “cuddle” was warm.

* Before class he heard younglings singing.

* He has plants in house from sprouts on ship. Plant grew “bud.”

* Engineers got seawater temperature right. He took off shoes and stood in water, sighing. He didn’t care about pants getting damp. Cried until shirt was also damp. Humans very endlessly wet.

* He missed “Doritos.”

* Adrian helped food scientists make taumoeba dried paste. Made it crunchy after heating. We fused it into triangle form. Told him it was Tauritos. That made him laugh-cry. Laugh-cry is rare and precious.

* He remembered Eridians have no gender rules.

* We made him celebration outfit. Used metals he calls pretty. He can see frequencies named “colorful” and “shiny.” These make humans happiest.

* I gave him hug when he wasn’t expecting it. Easier to hug close now with exosuit. Hug when Grace sitting down so he does not fall over.
