The way I did there (see the changeset: https://www.openstreetmap.org/changeset/45664904#map=14/49.7397/5.5428 ) is to tag barrier=fence the ways delineating the meadow (so the polygon is tagged as landuse=meadow + meadow =agricultural + barrier=fence).
To me in your picture, the ditch also delineates the meadow so I would put it as a part of the polygon of the meadow (I mean, not drawing new nodes for the ditch). In some cases where there is a large hedge (> 1m), I would map it separately from the meadow limit.
