Timber farm!
Row of pines.
Row of mixed hardwoods.

Repeat.
The pines grow fast and like a pyrimid shape. It puts stress on the mixed hardwoods, which makes them grow tall and straight, perfect for veneer timber.
Basically, you plant them, mow between the rows twice a year to keep weed competition down, and after 5 or 6 years you don't have to mow anymore because the pines will fill in and keep the weeds down.
Its low maintenance, qualifies as AG, and can qualify for state reimbusement for errosion control programs, conservation reserve, classified forest, classified wildlife habitat, etc....
You won't see any profit from it, but your kids or grandkids might.
We planted ours around 1980. The tress are topping 40-50 feet and the hardwoods are finally topping out over the pines.
Fun to watch the passage of time with the growth of trees.
