I am not so religious about covering tracks in farmland. The point is
that huge polygons tend to break much more often and tend to be much
harder to modify/fix. I personally keep polygons small for that reason.

Also there are much more fine grained tags for agricultural land e.g.
meadow etc - Typically when you map farmland and do it right it does not 
grow that huge. You have small wooden strips, waterways with
scrub around, roads etc. I typically even break up at field boundaries
seen in differences in plant growths etc as thats typically the
boundary for changes in usage in the future.
