Unless it has been changed recentlly that "Normal Agricultural Practice" was the way TN law read. Some years back a good many farmers around here were Drilling their wheat fields twice, once normally & then they would go around again with the drill set not to cover the seed. They were charging dove shooters to shoot over their fields. Many were caught, charged & fined, but the farmers weren't charged, they weren't shooting. The shooters of course were not given the opportunity to examine the field before they paid their fee to shoot. I don't know how this was eventually settled but haven't heard much about it lately. I think though that most shooter just got to the point they refused to pay to shoot over a field which had been planted in winter wheat, thus ending the unscrupulous profits.
