I will buy a small farm this year (if I'm lucky) and I do believe your general approach is very interesting.

Let see how it continues.

Regarding sprinkler etc. I saw a bigger drown spraying stuff. If the autonomy is very reliable you could refill it regularly.

Sprinkler I'm really not convinced but we don't have a lot of sprinklers in field in Germany.

Might be a little bit waist full from a water perspective
