The U.S. Department of Agriculture says Iowa cropland value dropped the sharpest in the United States in the past year, falling 6.3 percent as low grain prices weakened the value in the nation’s leading corn producing state.

Cropland value fell to $8,200 an acre after climbing to $8,750 last year. Iowa cropland values shot up more than 56 percent from 2011 to 2014.

Cropland values declined in 10 states while the others remained static or grew.

Texas saw the biggest jump at 9.5 percent to $1,840 an acre.

Nationally, cropland grew an average of 0.7 percent.

New Jersey has the most valuable cropland at $13,500 an acre after a 3.8 percent increase. California is second at $10,690 and Arizona third at $8,320 an acre. Iowa is fourth.
