BOYDEN, Iowa (AP) — Some farmland near Boyden in northwest Iowa’s Sioux County may have set a new sale record. The Sioux City Journal reports the 80.5-acre plot sold on Thursday for $21,900 an acre. The auction company, Vander Werff and Associates Incorporated, says the land has an estimated corn yield of 110 bushels and soybean yield of 43 bushes. Auction spokesman Todd Hattermann declined to name the buyer. The seller is Henry Boelsman, a longtime farmer.

In December, a 74-acre plot near Hull, also in Sioux County, sold for $20,000 an acre. A survey of real estate agents estimated the average farmland value in 2011 was $6,708 an acre. That’s up over 32 percent from 2010.
