The U.S. Department of Agriculture’s National Agricultural Statistics Service (NASS) just released the final 2012 Census of Agriculture results sharing a wide-range of information about agriculture at the national, state, and county level. This census provides a wide range of demographic, economic, land, and crop and livestock production information. Much of the Iowa data is only collected and reported as part of this every-five-year census.

According to Iowa’s Secretary of Agriculture Bill Northey, “The results again show the tremendous economic impact of agriculture on our state’s economy and the importance of Iowa agriculture nationally. It also contains valuable information about the conservation practices used on farms, showing that farmers use no-till or conservation tillage on two-thirds of their crop acres.”

The overall number of U.S. farmers dropped 4.3% from 2007, to 2.1 million. The 2012 Census of Agriculture data show the following key trends for Iowa.

– In 2012, the value of agricultural products sold by Iowa farmers totaled $30.8 billion, up nearly 51 percent or $10.4 billion from 2007. Crop sales accounted for $17.4 billion of the total and livestock sales accounted for $13.4 billion, up 68 and 34 percent, respectively, from 2007.
