Hidden Dangers of Prussic Acid

Prussic acid is a herbivory defense mechanism used by numerous plant species, but is most-associated with sorghum and sudangrass hybrids. While the risk of prussic acid poisoning is greatest in sorghum species, several additional species present across South Dakota can produce prussic acid at varying levels of concern.

Does Water in Grass Change How Much Cattle Drink?

Ranchers know that cattle need clean drinking water every day. But the water already inside grass is easy to overlook. As grass grows older and dries out during summer, cattle may need more water from tanks or other sources.

Recent Rainfall Likely to Improve Fall Herbicide Applications for Noxious Weed Management

Under hot and dry conditions, weeds are stressed and herbicide activity decreases, leading to poor management. While recent rain events have impeded row crop harvest, the moisture is welcomed to improve the activity of fall herbicide performance for noxious weeds in pastures and rangelands.

Natural Resources & Conservation

South Dakota is home to many unique land, water and wildlife resources. Our experts and partners offer research-based information through to help people enjoy, preserve and profit from these natural resources.

Noxious Weeds Should Be Closely Monitored for Management

Pasture, rangelands and rights-of-way are starting to turn yellow, purple, or even a mix of both due to rapid growth of noxious weeds. Now is the time to implement management tactics to ensure the weeds do not outcompete desirable vegetation and invade adjacent land.

Red Fescue (Festuca rubra), A New Grass in the Black Hills: Friend or Foe?

Red fescue (Festuca rubra), a cool-season, dominate rhizomatous grass, has started showing up on disturbed ground near meadows and forests. While it is not a state noxious weed yet, its spread has raised questions from producers.

Keep Your Pastures Guessing: Why predictable grazing is costing you

Your cattle don't care which pasture they're in. Your pastures, on the other hand, care enormously. Give them something to work with, and keep them guessing.

Setting Stocking Rates With Flexibility in Mind: A decision framework for uncertain years

Setting stocking rates during years when moisture is unpredictable does not require perfect information. It requires a framework that protects both your land and your options.
