What's the best way of creating farming plots underground on stone?

Is there a way to tell dwarves to dump buckets of water onto stone?

You have to dump it from a level above using a pit/pond zone.

Since water evaporates, you won't get too far with the pond zone, but you can try and create a buffer reservoir above the farm before you flood the ground. You can reasonably fill a 3x3 chamber by using buckets, then release that with a floodgate depending on how easily you can access water, but aquifers and pumps can work well, too.

yes, but you have to do this from one layer above.
Channel a hole in the flore above the farm to be, and
create a pit/pond zone that covers the hole. In the options
you can tell it to fill it with water.

Blind made a quick tutorial about wells, which covers the same concept

I need to redo these with the new tiles, but this is a good efficient way to do bucket irrigation.

Farming was also nerfed in general, correct? If so how many dorfs would a simple 1x7 irrigation plot feed nowadays?

So. There is. What you do is. you mine out a room. Then inside the room, leaving a block wide passageway around the outside, you dig a 1 block smaller channel. so if you started with a 6x6, you want a channel dug out to 4x4. Doesn't have to be 4x4, can be 4x6. but you need a flat walkway around at least 2 edges of it because of how the dorfs do buckets before/after they get tasked to fill pond. Then on that ramp around the outside you put in at least 4 pit/ponds on the corners. The pit/ponds should be a single 1x1. If you do a longer pit, like 4x6 or whatever then you will need at least 6 pit/ponds. Then you set the pit/pond to fill with water. You only need 1/7 water depth or whatever because what you are looking for is the mud, wait until the fill/evaporation cycle gets mud into the entire channel, then remove the pit/ponds on the perimeter, then build the farm plot as normal. The way the dorfs do buckets for fill pond is a single dorf will get tasked to fill a single pit/pond. If you leave the entire channeled out room as a single pit/pond it won't get filled because of the evaporation cycle. After they fill they will usually just drop the bucket where they were standing with the pit/pond fill point in front of them. If this area isn't flat the bucket gets stuck on the ramp or whatever and it becomes "not findable" sometimes. So to avoid having to constantly make a bunch of buckets over and over, make sure there is a flat walkway to the fill points.
If you get little pyramids in the center of the channeled out bit just go one Z level down and remove the ramp. That will flatten that 1x1 out.
You want to keep the farm plots small in width but long in length so water splash can reach across the channeled pit. If you put multiple farm pits into a room make sure to leave support columns up or it will collapse.
