Summary0004164: In mountain biome, clay cannot be farmed, and grass does not regrow
DescriptionClay cannot be farmed properly. A plot can be designated and built on the clay, but the resulting plot cannot be planted -- you get "No seeds available for this location" in all seasons.

Natural clay tiles on the surface can start out covered with grass, but if an animal grazes it all away, it does not grow back.
Steps To ReproduceEmbark somewhere with clay. Build a farm plot on it. Get some above-ground seeds. Attempt to mark the plot for seeding.

Embark somewhere with clay. Mark a pasture on it. Let your animals graze there. Wait for it to grow back (or not).

Does irrigation help with the farming part?

All right... the clay is above ground, albeit currently roofed over. So I guess the easiest way to get water on it is to build a staircase to nowhere, then designate ponds next to the staircase.

Did that, and the water hit the clay and froze (it's currently a bit chilly here). This gave me tiles that appear as "Muddy Ice / A dusting of mud / Inside Light Above Ground". One of the ponds got filled twice, and the resulting tile appeared as "Ice Wall / Inside Light Above Ground". I turned off the ponds at that point.

On one of the "Muddy Ice" tiles, I build a 1x1 farm plot. The result is "No seeds available for this location". Maybe when the ice melts something will change...?

Well, no surprises here. Come summer and the thawing of the ice, I had a bunch of water on the clay (the ice wall actually produced more water than went into it, I'm fairly sure).

The existing 1x1 plot, newly moistened, still shows "No seeds...".

I built a new 1x1 plot on another wet tile, and it also gave me "No seeds...".

It's quite possible that this clay is in a "mountain biome", if that matters.

If it's in a mountain biome, then it's perfectly normal - no surface plants are capable of growing in a mountain biome. Was the clay revealed by channeling through the surface or by just clearing away the grass (e.g. by building a dirt road)?

It was revealed by having the grass eaten off it by grazing animals. So maybe the bug is "clay in a mountain biome starts with grass on it"? And/or "farm plots can be built in biomes where you'll never be able to plant them"?

Well, there is mountain grass, so it should regrow when grazed. Maybe a test in a non-mountain biome should be conducted.

Perhaps there should be a new soil type for mountains (either hardcoded or having some special token in the raws) which is incapable of supporting any plant life other than grass (and which would be treated like stone for the purposes of trying to place farm plots).

If I can figure out exactly where the line between my biomes is, and if I can find some clay on the north side of that line (the side where shrubs and trees and farm plots and grass regrowth all seem to work -- although I'm only sure I've done so on sand, not clay), then I'll see about testing there.

Far as I can tell, that map doesn't have any clay in the non-mountain biome; it's sand there. So I can't conduct any tests on clay in non-mountain biomes there.

The lack of regrowth after grazing does seem like a real bug, though, given that the raws specify certain kinds of grass are supposed to exist in mountain biomes.

Having this problem too, with grass not growing back in mountain areas after grazing. Happens both with sandy clay and regular sand.

correct description is "clay in a mountain biome starts with grass on it"

I agree with Kogust on this. It seems mountain biomes don't support vegetation but start out covered in grass anyway.
