Land owner regulation vague?

Buster, I own property in Ripley County, but prior to purchasing it I already had a lifetime license. I have a couple of questions pertaining to being able to write land owner tags. Is there a minimum number of acreage, say 40, and do you have to farm it, grow trees, etc. to be able to write land owner tags. Do you have to show proof that it is being farmed? My land is mostly wooded with only a few acres that I would consider tillable, and it is not actively farmed. Prior to my purchase it was used to pasture cattle.
