Grain and prices within 50 miles
Bids are posted elevator prices within 50 miles of the county middle, or of your own field or saved place in this county when this device has one (each row says which), best and nearest, never a buyer's name. Not a contract; call before you haul. Livestock lines show where the 2022 Census counts 1,000 head or more: milk for milk cows, feeder cattle for beef cows, live cattle for cattle on feed, hogs for hogs, hay for all cattle.

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 South Dakota county rate, side by side: South Dakota 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 uses this year's rent over the 14-yr trend. The calculator below starts from that trend and lets you put in your own yield and price.
Land value
The census value is this county's, from 2022. The survey figures are the South Dakota 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.
