That was my first question also - mention in replies are 100-240 m rages which is useful to know.
FWiW here in W.Australia 4,000 acres is a mean size for farms (with a skew distribution) .. roughly 4 km a side for a square boundary.
I can see these being useful for occassional monitoring around a central solar powered collector - with stakes and flags on the sensors tags so they can be picked up again and recovered as wheat grows.
These are the practical issues of modern grain farming (and many farms are much much larger - the mean is skewed by many small plot farms while the bulk of the industry revolves around a few hundred much much larger concerns).
So Lora is probably more practical. We had to trigger a solenoid so needed a bit more power anyway, but could reliably run off a LiIon battery with a solar panel for recharging. Makes the whole package more complicated, but it worked well.
The extra range or Lora means I didn't have to implement a mesh protocol. I wasn't looking forward to having to test a mesh network, point to point is much easier.
