Effects of Late Spring Frost on Alfalfa

Forage research indicates that, although alfalfa is considered to have good cold temperature tolerance, minor frost damage may occur when plants are exposed to air temperatures slightly below freezing for several hours, and more severe damage will be seen when temperatures drop below 25°F for four or more hours.

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.

2020 Corn Growing Degree Days Update

Spring planting progress of corn in 2020 has been much ahead of a typical year in South Dakota. Crop development, however, seems slow.

Lessons From Alternative Calving Workshops

Recently, the South Dakota Grassland Coalition and SDSU Extension held workshops across the State focused on sharing information from experienced livestock producers who have switched to a calving date more in sync with nature.

Flooding and Sump Pumps

For many homes with a basement or crawl space, a sump pump and drainage system can help reduce the risk of a basement flooding from high water table situations. Here are a few tips for making sure your sump pump is working as it should, and you are not causing problems for your neighbors downstream.

Fall Frost and September Climate Outlook for 2019

September 2019 has been pleasantly warmer than usual, and our crops need every bit of that warmth to reach maturity before our first frost arrives. Fortunately, temperatures have cooled slightly this week but just to near average for this time of year.

Multiple Rounds of Severe Weather Bring Heavy Rainfall, High Winds, and Soil Erosion

A combination of tillage, no residue, and lack of crop canopy can lead to severe erosion and topsoil loss in the face of extreme weather patterns in the spring. The most effective strategy for producers to adapt to these extreme events is to improve soil health.
