Multiple farm-field buildings around a single farm field?

[Lord Screamo The Giant Pacifier]

I know it's possible to have more than one farm-field building around the farm fields, but does this evenly spread out the production among those buildings?

Possibly a stupid question, but I want to make sure.

Yes. One farm without any bonuses can handle about 8 fields with max workers and storage close by. When I get more than 10 fields in an area I will place an additional farm with another worker to spread the load and to be able to till all fields during storm and harvest all before next storm hits.

I do it quit often and it definitly works.
There is one thing that bugs me though and that is that facing and position of the farm does not seem to influence how the plant. They seem to choose a starting point and then plant from there that can lead to one side cannibalizing the shared fields before planting on the fields that only they can reach and that leads to less efficency. So keep that in mind when you put them down.

I generally split the field so the building influence squares don't overlap, especially if they're of different types. So an herb on one side and a small farm on the other, splitting the available fields down the middle. I notice most of them get harvested and my people get back to the hearth in time for a little rest.

This definitely needs the farm buildings (or the fields) to have a priority option, like camps have, if you want to be perfect. I just got two batches of fields from two glades glued together and had to build 3 farms to use them all. One of the farms ends up having access to 15 fields and most of the time the workers there plant the shared fields first and screw the other two farms (10 and 9 fields).
Or at least make it possible for same farms to farm sown fields, even if another farm planted them.

For a full length storm (P15+) you might need 1 worker for ploughing, 2 workers for planting, and 3 workers for harvesting on a field. A second farm building makes sense.

Sometimes you can find yourself with essentially two adjacent sets of large fields. Let's say we put one farm at each end and another farm in the middle. The farmers in the middle may well not evenly spread out their work and may well concentrate on one set of fields rather than the other.
