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.

Farming is all about timing. Use our research-based resources for planting, growing and harvest.

Forecasted Cold Temperatures Can Be Used To Cool Down Stored Grain

If temperatures are forecasted as being well below freezing, it would probably be a good time to start thinking about cooling stored grain. Cooling grain reduces the activity of stored grain insect pests and suppresses any mold growth that may otherwise occur.

Creating Management Zones Using Electrical Conductivity

The first step to practicing zone management is to identify the variations that control yield. There are various methods for characterizing soil variations within a field, and among them, electrical conductivity measurement is one of the most-reliable.
