Laws vary in different states. In Iowa you could do it on a hand shake but a legal contract would likely give you more control. Google "Land Rental Agreement Forms" and you will find many forms to work with.
Your control is in the agreement, written or verbal. I would suggest either be with a trusted witness.
This is my opinion. I am not a lawyer!
I never found cash rent as productive as CRP payments but you do have the Russian Olive problem to consider.
