The Saudi's have a special relationship with Arizona. They have irrigated alfalfa farms there.
They use the hay to feed their dairy's back home.( and the Royal horses ) Aquafers are drying up there for everybody.

NO non-US citizen should be allowed to own more than 5 acres in America.

The chicken farms in my area are being bought up by Vietnamese at an alarming rate.

Is the mineral rights worth anything?

Probably not since that wasn't even discussed when I bought my house.

The group from New Zealand that bought the dairy farm I worked at here continuously adds farms when they can. The farm here is a 3 year payoff deal they've had for almost 3 years. They purchased another dairy in Tillamook County
last year and to my knowledge own 8 or 9 farms in Missouri. All of the investor's own dairies in Kiwi land and some other Countries. They cut farm hands to a minimum and equipment as well. They pay out the ass for contract work/machinery
instead of just adding a few more tractors. They were hiring a farm boss here for around 100K annually a while back
