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.

Fall Grain Storage Tips

As the temperature drops, don’t forget to check on your stored grain. Although most of the South Dakota grain harvest was sufficiently dry this year, we still need to watch grain storage temperatures and conditions.

Two rows of corn at V5 leaf growth stage looking down from above. Between the corn rows there are 3 separate cotton strips placed on the soil surface just before burial in a 2-inch-deep trench. The cotton strips are numbered for their identification after recovery at three different dates.

Cotton Strip Soil Test: Rapid Assessment of Soil Microbial Activity and Diversity in the Field

Soil has always been considered as a living system due to its biological components: fungi, bacteria and plant roots. Under several ongoing research projects, we started researching how we can use ‘cotton strip assay’ to compare different cover crop mixes to optimize field soil activity and build up better soil health.

Using Data for Better Seed Selection

As harvest wraps up across the region, winter preparation and planning for next year begins. Yield trial results are a key component when making sound seed selection decisions.
