Higher market prices led to a big jump in the value of South Dakota's corn crop production in 2011.
The U.S. Department of Agricultural estimates the value of corn for grain was up 36 percent from 2010 to $3.95 billion.
Soybeans were valued at $1.72 billion, and hay was valued at 1 billion.
The wheat crop was valued at $799.5 million and alfalfa hay was valued at $793.1 million.
Crop values are determined by multiplying the average market price by total production.
