Land rent, value, sales
Cash rent
Dollars per acre, USDA NASS county survey. A break in a line is a year with no published survey.
Every published Wisconsin county rate, side by side: Wisconsin cash rent by county.
Share of gross is a past year, all observed: that year's rent, that year's county corn yield of the same practice and the state price received, USDA NASS. Rent per bushel is withheld here: it needs the county trend, and the trend is withheld (see the corn yield section). The calculator below takes your own yield and price.
Land value
The census value is this county's, from 2022. The survey figures are the Wisconsin average for 2026, from the USDA NASS Land Values report. NASS publishes that survey by state, not by county, so this page does not scale one into the other.

Counties that share a stretch of boundary. A rent from an older survey year carries its year and stays out of the median; one more than three survey years old shows n/a. The corn median here needs 15 published years, so a county with fewer shows n/a even where its own page gives a median.
