We have leased our 20 acres of hay ground on a five year lease. He pays the water assessment and the taxes. We also get 10 ton of hay per year. This ground has produced three ton to the acre some years.
In a nut shell he pays $1100 + 10 ton hay for the privilege of using our ground. Check with your local Extension Agent as well. He may be able to tell you what is normal for your area.
