Corn

Nearly one out of every three dollars generated by South Dakota agriculture starts in a corn field. Two of every three rows of corn become ethanol. It’s the most-planted crop in South Dakota, and a strong partner in the production of livestock. Best management practices for corn production, developed at SDSU, are your window to enhanced profitability.

Collaborating with South Dakota Agricultural Experiment Station at SDSU, throughout the growing season, our team showcases local data collected from test plots in a field near you.
