I might as well add this. It's the farm plan I have for my golems.
The black square in the center is a chest set into the ground. I'm fixin to change that to an ender chest so I don't have to hassle with these guys. Two wood golems do the rounds. Since the straw golem has to be intelligent, the radius has to be no bigger than this. For that reason I went with speedy wood golems instead of perceptive ones, and I found some objects at the edge were never picked up, so I reduced it by a block all around. I might have been okay either changing them to perceptive wood golems, or building a wall all around to keep everything inside, but production was already enough that I didn't need that extra band. I'll have to try to research spectacles, then everything will be cool. The two blocks in the middle are jack-o-lanterns and the dark orange blocks are water with a j-o-l above them. Problem with that was the golem would jump on the block then trample the farm on the other side so I added a slab on top, but that did block the golems, so I raised the j-o-l up 2 blocks and covered the water with lillies. It's not enough room for me to pass under the j-o-l but the golems are fine. I made the dirt striped in this image because it's pretty.
I gotta warn against giving these guys a way out of their farm. I used to have a gate and occasionally the straw golem would get out and harvest a swath of my nearby cactus and cane. Took me forever to figure out why these plants over 20 blocks from the edge of the farm would suddenly be shortened. I blamed it on flux for a while, hehe. Also the wood golems will show up in the cave below trying to pick up items, even if they have to go 100 blocks away to get to an access point to the place they detected a loose item. So, block them in.
I tried using some Xychorium Soil and I love that stuff. It would be easy enough to make an entire farm out of it, but I prefer to use them 8-deep around the water pools with cane planted there. I only have 8 cane planted and I get as much of that stuff as I do of wheat; it's impressive.
Edit: I just remembered I moved some of the water plots out a little to ensure coverage, after I made this plan. So the 2 that are horizontal with the chest are fine, but the rest need to be moved out from the center by 1 block. That gets most of it.
