I guess it depends on the state. You can get 150 acres of pines planted for probably around $10K where I live. Regional universities will do it. I suspect it's cheaper in Iowa.

Also, depending on the state, the entire property doesn't need to be planted, just a portion that probably varies state to state.

Here's a Forbes article on it.
