Silos in Sector 2 and 5

Here's a silo set-up that goes across the border of sector 2 and 5 on your island.

The squares servicing the field on the left I've given black writing, and the orange writing goes to the field on the right.

On the left there's 6 farms and 6 silos, with an average walk distance of 46.7 seconds for either side. You also get a 3x2 spot along the top where I'd place a watermill. You could do a friary, but I'd make a friary closer, less important for the watermill since water is rather plentiful.
On the right there's 7 farms and 7 silos, with an average walk on either side of 44 seconds.

Both sides nicely under 48 seconds average, so will feed your buildings nicely.


Here's an image of the same layout showing the walk times (note that the number in the watermill's space covers as if that space was a farm/silo, not a watermill.
