Low Temperature Effects on Winter Wheat

Low temperatures during the early morning hours of May 9–11, 2020 may have had detrimental effects on winter wheat in some areas of South Dakota. However, cooler spring temperatures that have slowed the winter wheat development this year may have actually been beneficial to S.D. producers, as later-maturing wheat is not as susceptible to injury from freezing temperatures.

Strategic and Scenario Planning in Ranching: Conducting a Ranch Inventory

During times of belt-tightening, it’s imperative to make sure all the resources of the ranch are being utilized as efficiently as possible. Conducting a complete ranch inventory is a perfect time for ranch managers to take an in-depth look at their operation.

The Fusarium Head Blight Prediction Tool Indicates High Risk

Winter wheat is starting to flower. It is important to monitor weather conditions from when wheat is heading until flowering to decide the need for fungicide application to manage Fusarium head blight.

Understanding Hay Inoculants and Preservatives on ‘Dry’ Hay

As haying season approaches, producers across South Dakota will begin preparing to get out the baler. In recent years, it has been quite difficult for many producers to put up quality, dry hay. This often results in growers considering using inoculants and hay preservatives.

Range Improvements, Grazing Systems and Net Present Value, What is the Right Balance?

As farms and ranches across South Dakota continue to endure increasing costs of production while receiving less cash for grain and livestock marketed; ranch managers must be extra diligent when implementing new range improvements and grazing systems on their ranches.
