I'd agree, if needing definitive legal response an attorney would be advised.
Generally, I'd say your good to go.
On a non-legal opinion, we've had our barns, cattle, livestock, machinery in action (planting / harvesting) and farmsteads photographed by multiple parties; including news sources, various nature magazines, and freelance photographers. Some were nice to ask the properties "owner name" to maybe include in credits although the majority didn't.
In casual, we discussed with a local "friend' Attorney and he basically indicated it's the same as essentially any privacy laws... comes down to "identification" of Subject in photograph & Intent. If you're not providing an address, precise location or signage that provides identification you're normally not required to obtain permission or rights to use photos in publication, internet, etc. If you indicate identification of subject, you "may" need to obtain permission. The "may" is loose.. Exp: Old Bridge, Barn or Water Stream on property and "identified" normally would not require permission; a rustic photo of aging Ft Porch with address on post of an active Farm Residence may be more likely to obtain permission... but likely not specific enough.
Similar to photographers on ground taking photos of action scenes, storm damage of homes and individuals within the photos, fire damage: close aerials of properties during or after fires, or more simply landscape photos of sunset/sunrise that include homes, barns, etc are not required to seek permission.
You may specify location as: photos from SW Dakota, or even stating "in a small town: Spearfish, SD", etc. You're not providing enough detail to identify the subject violating their privacy.
Other examples: The Amish Community attracts photographs, people often take photos of this society's homes, lifestyle, dress, buggy, etc. Some are used in publications, and doesn't require permission to exhibit,
If you've ever attended a State Fair or Photography Contest where hundreds of photos on are display, and categories: People, Places, etc. These don't have permission and are used in multiple publications.
All that said... if I take photos and I see parties on property... I normally take the effort to meet and ask if they'd mind. Normally if it's not a photo of them... they don't mind, often happy to have photos taken.
Applying consideration & thought... works best. Exp: I wouldn't photograph a KY Distilling Facility, especially aerial... might encounter a negative response.
