You don't profit from the 125$ cash rent ?
You can cost share the chem and labor also. But I know most pf groups have some chemicals on hand. My coop sells/gives them some roundup or other stuff each year.
There's areas here getting $300/ac.... sure they could get maybe 325 from some sucker but is that 325 gonna be locked in 10 or 15 years? Nope... year or two then they move on from not putting dry on and soil is depleted. You got to understand the average rent in your area isn't the big number u hear at the coffee shop
Anytime I have put land in CRP for 10 years the competing rental rate has gone up significantly by the time it came out. That is why I never put land in CRP for more than 10 years.
