Heya, thanks for adding detail to the farmland here. From the aerial imagery, it looks like a lot of this is unimproved grazing land (and I’d expect that of the area) — if so, it could be more specifically tagged as landuse=meadow meadow=pasture.

See https://wiki.openstreetmap.org/wiki/User:Gurglypipe/landuse for the current consensus on farmland tagging in NW England.

Hope that helps, happy to answer questions about if it it’s not clear, or if you have improvements to recommend.
