The increase in land values was mainly due to higher crop production values, driven by market price increases in 2007 and 2008. The change in crop revenue led to land value changes ranging from -1.6% to +21.8% by county. The capitalization rate change increased land valuations by 3.8% in all counties, while the cost of production index decreased land values by 5.3% in all counties.
