As others point out, it looks like a variable rate custom arrangement or a very restrictive c/s arrangement.

15% of the crop? Tenant is able to remove & do what he wants w/his 15%?

Tenant has to deliver landlord's crops....where?

Who manages? Landlord says 25,000 ppa corn & 100# N is enough. Cuts into your 15% pretty good.

Landlord says, "we're (= YOU!) going to grow white corn! $0.25/bu premium! So, you're along for the ride.

Landlord says you let the beans get weedy, no more money for rescues. Beans make 30 bu in weeds.

Landlord says "you farm xxxx acres, but this farm WILL be done first. My 85% allows me to dictate that.

Landlord says crop & hail ins is too expensive. Not sure how your 15% coverage would work.

Landlord says his beans need to be "rotary hoed" to save the crop. You don't own a hoe. ??

My answers contain some experience. So, is this all worth 15%? 200 bu/A corn @ $3.50 (dried/shrunk?) = $700/A x 15% = $105/A, 150 bu/A corn = $78/A
