...of where Iowa, Wisconsin and? Minnesota meet. (yes Illinois meets there too but that land is not realistically priced for farm ground)

What would be the average number of round bales per ton of alfalfa hay produced?

What is the average production for first year?
What is the average production for second year?
What is the average production for third year?
What is the average production for fourth year?

How much on average does it cost to hire someone to plant alfalfa ground (including the oat cover crop).

Thank you for your time and efforts.
