I too live smack dab in the middle of corn country. I own 147 acres of tillable ground. I use to farm it myself until it got to expensive. My tenant farms it for me now and it takes him about two hours with a 32 row planter and GPS. Last year it averaged 175 bu per acre, dry. Wet 192/bu/A.
This year look for corn and beans top go hog wild, price wise. Due to the Corps of Engineers flooding millions of acres along the Mississippi.
Have you seen any oxen out there?
