Yes, I was unsure about the correct tagging and had consulted the Wiki. However I think you are right that I got it wrong. I have changed the tags as you suggest, but also added Meadow=Paddock
as per  
 https://wiki.openstreetmap.org/wiki/Tag:meadow=paddock?uselang=en

I have also added the stables which are there.
I take it that you spotted it due to an interest in Horses since you have one as your profile picture?
