SDSU Expands Free Nitrate Testing Across South Dakota

By Scout Nelson

South Dakota State University (SDSU) Extension is expanding its free nitrate testing program by adding more drop-off locations across the state. The additional sites make it easier for livestock owners and forage producers to test hay and forage as dry conditions continue across much of South Dakota.

Dry weather can cause nitrates to build up in forage crops such as oats, sorghum, sudan grass, and corn. High nitrate levels can create serious health risks for livestock, especially pregnant animals and ruminants like cattle.

Testing forage before feeding helps producers identify potential problems and make informed feeding decisions that protect animal health.

To improve access to testing, SDSU Extension has added new sample drop boxes at livestock auction locations in Worthing, Yankton, Mitchell, Kimball, Platte, Burke, Winner, Presho, Mobridge, Philip, Faith, Martin, St. Onge, Belle Fourche, and Newell.

Extension staff will collect samples from these sites each week, and producers will receive results after testing is completed.

Free nitrate testing also remains available at SDSU Extension regional centers in Aberdeen, Lemmon, Mitchell, Pierre, Rapid City, Sioux Falls, Watertown, and Winner. Additional drop-off locations include Berg Agricultural Hall and the Raven Precision Agriculture Center on the SDSU campus in Brookings, Sioux Nation in Fort Pierre, and the Bennett, Butte, Clay, Fall River, and Haakon County offices.

SDSU Extension encourages producers to collect forage samples in a gallon-sized plastic bag or a small paper bag. A completed submission form, available at each drop-off site, should be attached to the sample. Proper sampling methods improve testing accuracy and provide more reliable results.

The university also offers educational resources for producers who want to learn the correct way to collect forage samples. A free online guide explains how to use nitrate test strips at home, while additional drought resources are available through the SDSU Extension drought webpage.

Producers who have questions about nitrate testing or forage safety can contact SDSU Extension specialists, including Taylor Grussing, Jaelyn Whaley for additional guidance.
