The impact of recent changes to the U.S. commodity program and efficac
y of environmental regulations designed to discourage continuous corn
rotations will depend upon the value farmers place on corn base acreag
e. This paper estimates this value by assuming that the benefits of ac
cess to the program are capitalized into farmland rents. Using Iowa re
ntal survey data and a hedonic pricing approach, the rent gradient for
base acreage is found to be on the order of $12 per acre. The discoun
ted stream of returns to base acreage suggests an asset value for corn
base of approximately $200 per acre.
