Soybean is one of the major row crops in the United States. According to the USDA National Agricultural Statistics Service, the acreage of planted soybeans increased in the U.S. from about 64.2 million acres in 1996 to 77.5 million acres in 2009. The soybean production also increased from 2.38 to 3.36 billion bushels from 1996 to 2009 in the U.S. In 2007 and 2008, the soybean production was estimated at 2.7 and 2.9 billion bushels, respectively. In South Carolina, the acreage of planted soybean ranged from about 560 thousand acres in 1996 to 590 thousand acres in 2009. Table 1 shows the South Carolina soybean production by county in 2009.

The highest estimated acreage was for Florence, Darlington, Williamsburg, Horry, Dillon, and Lee Counties. The highest soybean yields were estimated for York, Oconee, and Dorchester Counties (34, 32, and 30 Bu/acre, respectively). The State average yield was estimated at 24.5 Bu/acre for 2009.
