survey of Iowa land values placed the average at $7,863 per acre, compared with $7,183 last year, Successful Farming reported. The survey also asked participants about land values going forward and while the state average dips a little for 2018 at $7,849 per acre, it jumps up to an average estimate of $8,307 in 2020 and $9,632 per acre in the year 2025. ISU ag economist Wendong Zhang said the internal rate of change is more telling than the actual survey estimates. "We think the bleeding has stopped," he said. Cash rents, on the other hand, have declined.
